Scientists aim to establish a groundbreaking laser system in one of the moon’s coldest craters to significantly enhance the navigation capabilities of lunar landers and rovers.

Ultra-stable lasers are vital for highly precise timing and navigation systems. These lasers operate by reflecting a beam between two mirrors within a cavity, maintaining a consistent beam speed. This precision is largely due to the chamber’s size stability, which neither expands nor contracts. To achieve this, mirrors are typically maintained in a cryogenic vacuum, insulated from external vibrations.

The moon hosts numerous craters at its poles, which lack direct sunlight due to minimal axial tilt. Consequently, these permanently shadowed areas are extremely cold, with some craters projected to reach temperatures around -253°C (20 Kelvin) during the lunar winter.

Junye from JILA, along with a research team in Boulder, Colorado, has proposed that these icy conditions, combined with the moon’s absence of natural vibrations and an almost non-existent atmosphere, make these craters ideal for ultra-stable lasers. The potential stability of these lunar lasers could surpass that of any terrestrial counterparts.

“The entire environment is incredibly stable,” Ye emphasizes. “Despite variations between summer and winter on the Moon, temperature fluctuations range only from 20 to 50 Kelvin, contributing to a remarkably consistent environment.”

Ye and his research team envision a lunar laser device akin to an optical cavity already developed in JILA’s lab, featuring a silicon chamber equipped with dual mirrors.

Current optical cavity lasers on Earth can maintain coherence for just a few seconds, meaning their light waves can synchronize briefly. However, the moon-based laser is projected to sustain coherence for at least a minute, which will facilitate its role as a reference laser for a variety of lunar missions. This includes maintaining the lunar time zone and coordinating satellite formations using lasers for distance measurement. Given that light from the moon takes just over a second to reach Earth, it could also serve as a reliable reference for Earth-based activities, as highlighted by Ye.

Although implementing this idea poses challenges, the rationale is sound and could greatly benefit future lunar missions. According to Simeon Barber from the Open University, UK, “Recent lunar landers have experienced suboptimal landings due to varying lighting conditions, complicating vision-based systems. Leveraging stable lasers for positioning, navigation, and timing could enhance the reliability of landings in high-latitude areas.”

NASA Plans Nuclear Reactor on the Moon: What Would Happen During a Meltdown?

NASA’s Revolutionary Nuclear Reactor Plans for the Moon

NASA has revealed its groundbreaking plans to construct a nuclear reactor on the Moon. This ambitious project represents a significant leap forward, potentially providing power for future Moon bases and sustaining long-term missions. However, it also prompts several crucial questions.

What is the estimated cost? Will someone need to remain on-site to manage it? And for the pessimists, what if it malfunctions?

<

The History of Nuclear Power in Space

This isn’t the first instance of nuclear technology in space.

In the early 1950s, NASA pioneered the development of the uranium-fueled “SNAP” (Nuclear Auxiliary Power system), designed for space exploration.

In 1965, just four years prior to Neil Armstrong’s historic Moon landing, SNAP-10A became America’s inaugural nuclear-powered satellite, operating for 43 days in Earth orbit.

Nuclear devices have since powered various deep space missions, including Voyager and the Mars rover Curiosity.

Some, like the systems depicted in the movie The Martian, utilize low-power solutions known as radioisotope thermoelectric generators (RTGs), which convert heat from radioactive decay into electricity.

Additionally, two Russian lunar missions have carried radioactive heaters for power generation.

In a quest to supply increased energy for its lunar initiatives, NASA is exploring small-scale nuclear fission systems that focus on splitting atoms.

In 2018, NASA successfully completed a test for a compact uranium-fueled nuclear reactor called Kilopower, roughly the size of a toilet paper roll, affirming its capability to power a lunar outpost with just four units.

While the concept of “moon reactors” may raise safety concerns, these reactors are designed with extensive safety measures including passive cooling and low-enriched uranium, minimizing the risk of catastrophic failure.

Nevertheless, the possibilities of a reactor mishap are intriguing to consider.

What If There’s an Explosion?

The reality of a nuclear meltdown on the Moon remains largely speculative. Current reactor designs suggest they won’t grow large enough to even be classified as a meltdown.

(A single Kilopower reactor can generate sufficient energy to power a handful of Earth homes for around ten years.)

However, the scale of the reactor isn’t the only factor influencing the consequences of an explosion; the lunar environment plays a critical role.

A nuclear reactor failure on the Moon would unfold quite differently than it would on Earth.

With no atmosphere or weather and only one-sixth of Earth’s gravity, scenarios involving explosions, mushroom clouds, and seismic aftershocks (triggered by atmospheric reactions on Earth) are less likely.

Instead, overheating could lead to a glowing pool of molten metal quietly cooling and solidifying without dramatic fallout.

Yet, this does raise substantial risks for personnel nearby due to radiation exposure.

Even with localized fallout being primarily contained, intense radiation surges still pose significant dangers.

A Close Call in Nuclear Space History

Fortunately, we lack detailed answers to this question, but an American scientist proposed a solution in the 1950s.

Project A119 was a covert initiative to detonate a hydrogen bomb on the Moon amidst the space race between the United States and the Soviet Union.

Thankfully, this concept remained in the planning stages and never materialized.


This article addresses the question posed by Worle’s David Martin: “What would a nuclear meltdown on the Moon look like?”

NASA Delays Artemis II Moon Launch Due to Rehearsal Challenges

During the crucial refueling process, initiated at 12:30 PM ET on Monday, mission managers temporarily halted operations twice to investigate a hydrogen fuel leak emanating from the rear of the rocket.

Although testing of the Orion spacecraft atop the rocket resumed, the hydrogen leak reoccurred in the final moments of the mock launch countdown.

NASA reported that a built-in control system on the rocket, designed to manage the booster in the countdown’s critical final minutes, “automatically halted the countdown due to a sudden spike in liquid hydrogen leakage.”

Engineers are also looking into audio issues that affected communication channels for ground teams during the wet dress rehearsals.

The four astronauts set to embark on Artemis II — NASA’s Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen — were expected to arrive at Kennedy Space Center on Tuesday afternoon after being quarantined in Houston since January 21 to minimize exposure to bacteria before their mission.

However, NASA has confirmed that the astronauts will not proceed to Florida as anticipated and will be released from their quarantine.

Instead, they will undergo quarantine again approximately two weeks before the next targeted launch opportunity, according to agency officials.

Artemis II marks the second flight for NASA’s Space Launch System rocket and Orion capsule, and it will be the first mission with humans on board.

This much-anticipated launch is set to advance NASA’s objectives of returning astronauts to the lunar surface.

The previous unmanned Artemis I lunar orbit mission in 2022 faced a six-month delay due to a hydrogen leak detected during the initial wet dress rehearsal.

The Artemis II flight carries significant importance, being the inaugural crewed mission aboard the Space Launch System rocket and Orion capsule.

“Our highest priority remains the safety of our astronauts, personnel, systems, and the public,” Isaacman stated on X, emphasizing that NASA will “proceed with the launch only when we are confident in our readiness for this historic mission.”

NASA Gears Up for ‘Wet Dress Rehearsal’ in Preparation for Artemis II Moon Launch

As NASA gears up for the highly anticipated Artemis II mission, the space agency is preparing for a crucial test that will determine the readiness of its powerful Moon rocket, the Space Launch System (SLS).

This essential “wet dress rehearsal” simulates a full launch day, allowing engineers to fill the SLS rocket with fuel and perform all launch operations up to 30 seconds before liftoff, mimicking real mission conditions.

The results of this rehearsal will be instrumental for engineers and mission managers to evaluate the booster’s performance and overall readiness for the Artemis II mission.

Set to launch by Sunday, Artemis II will embark on a groundbreaking 10-day mission, taking four astronauts farther from Earth than any humans have ventured before.

However, the actual launch date will heavily rely on the outcomes from the wet dress rehearsal.

“We’ll take some time to review the data and prepare for launch,” stated Artemis launch director Charlie Blackwell Thompson during last month’s press conference.

If the rehearsal proceeds without issues, NASA could announce a targeted launch date in a matter of days. Conversely, any problems could lead to mission delays.

Engineers and mission managers will execute a countdown to the mock launch scheduled for 9 PM ET on Monday. Over 700,000 gallons of cryogenic propellant will be loaded into the SLS in the hours leading up to the test, with NASA planning to livestream this crucial process. For more information, check out the Artemis Rocket 24/7 Live Stream at the launch pad.

As part of the rehearsal, mission managers will simulate the countdown several times during the final 10 minutes, which will provide essential data on the rocket’s systems, including an automated control that engages 30 seconds prior to launch.

Artemis II marks NASA’s second mission using the Space Launch System rocket and Orion capsule, with this being the inaugural crewed flight—a pivotal step toward NASA’s goal of returning astronauts to the lunar surface.

The Artemis II crew consists of NASA astronauts Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen, who have been in isolation at NASA’s Johnson Space Center in Houston to ensure they remain healthy prior to the mission.

On January 17, NASA successfully positioned the Space Launch System rocket carrying the Orion capsule at Kennedy Space Center in Florida. The agency initially planned a wet dress rehearsal for Saturday but rescheduled due to unexpected cold weather across the Southeast and mid-Atlantic.

Due to the scheduling changes, NASA has eliminated the first two launch windows (Friday and Saturday) for this month, which ends on February 11th. If additional launch opportunities arise, slots may also be opened in March and April.

Ensuring a successful wet dress rehearsal is crucial for a smooth launch this month.

Should issues arise during testing, NASA may need to return the rocket to the vehicle assembly building, reminiscent of the six-month delay faced by Artemis I’s unmanned lunar orbit flight after a hydrogen leak was detected during its initial wet dress rehearsal.

Since the passing of his wife in 2020, Wiseman has taken on the challenging role of raising two children as a single parent. He acknowledges the stress that comes with being an astronaut, noting that the thrill of the mission is often tempered by the sacrifices it demands from their families.

“I’m a dedicated single father to two daughters,” he shared with NBC’s “TODAY” during a candid interview with fellow crew members. “While it might be easier to relax on the couch with a football game, the reality is that we have four individuals ready to undertake extraordinary and groundbreaking explorations in our civilization.”

Wiseman expressed hope that the outcomes of this monumental mission will validate the sacrifices made by the families of the crew.

“We often look toward the moon and proudly state, ‘We’ve been there.’ However, for this generation—both current and future, known as the Artemis generation—they will look at the moon and proudly declare, ‘We are there,'” he emphasized.

Each astronaut will carry personal tokens on their historic flights around the moon. Wiseman and Koch will carry letters from their families, while Grover plans to bring a Bible, wedding ring, and a cherished heirloom for his daughters. Hansen will carry a moon pendant featuring his family’s birthstone and the phrase “Moon and Back.” These items serve as meaningful mementos and ways for the astronauts to connect their families to the journey.

Koch, a veteran of profound space missions, holds the record for the longest single spaceflight by a woman, having spent a remarkable 328 days on the ISS in 2019. Alongside fellow astronaut Jessica Meir, she made history with NASA’s first all-female spacewalk.

In a similar vein, Grover previously participated in a historic flight, flying the SpaceX Crew Dragon capsule to the ISS in 2020. Glover, a former U.S. Navy captain and test pilot, was transitioned from his position in the U.S. Senate when he was selected for NASA’s astronaut program in 2013. Grover and his wife are parents to four children.

Hansen, marking his spaceflight debut, is set to become the first Canadian to explore lunar terrain. A graduate of the Canadian Space Agency’s astronaut program in 2009, he previously served as a fighter pilot and colonel in the Canadian Armed Forces.

With three children, Hansen highlighted the camaraderie that has developed among the crew, remarking that they’ve formed a familial bond through years of intense training together.

The upcoming Artemis II launch will be only the second deployment of NASA’s Space Launch System (SLS) rocket paired with the Orion capsule. The inaugural launch, Artemis I, conducted an unmanned mission that circled the moon over three years ago.

Wiseman, Koch, Grover, and Hansen view this mission as a crucial stepping stone towards the Artemis III ambition, which aims to land four astronauts near the moon’s polar regions in 2027. Throughout their mission, the crew will practice docking procedures in Earth orbit, conduct scientific experiments, and evaluate various systems inside the Orion capsule, serving as a trial run for a forthcoming lunar landing.

“To us, achieving success is synonymous with landing on the moon during Artemis III,” Koch stated. “Success is always Artemis 100. Everything we do is centered around that.”

How to Determine the X and V Coordinates of the Moon: A Comprehensive Guide

Discover the Moon’s X: Captured from Tokyo in February 2025

Credit: Yomiuri Shimbun/AP Images/Alamy

Nearly a decade ago, my excitement surged as I captured my first telescope photo of the Moon. With a makeshift setup, I clumsily held my phone camera up to the eyepiece. After a few shaky attempts, I got a clear snapshot of the lunar surface, and shared it online with pride.

Unbeknownst to me, I had clicked the picture during a brief 4-6 hour window each month when fascinating features known as Moon’s X and V could be visible.

These lunar marks are optical illusions, revealing themselves only when sunlight strikes the rims of specific craters during the Moon’s waxing phase, perfectly aligned along the terminator.

The Moon’s X forms a bright X shape, illuminated by sunlight on the edges of three craters: La Caillou, Blanquinus, and Pulbach. Similarly, the V shape comes to life as sunlight hits the Ukert crater and nearby smaller craters.

To witness the Moon’s X and V, a telescope is essential. However, timing is crucial. The visibility of these features varies globally and is influenced by your local time zone.

The next waxing moon occurs at 5 AM GMT on January 26th. However, residents in the UK may miss it as the Moon will be below the horizon then. The best viewing opportunity on the evening of January 25th will be in New York, where the first quarter appears around midnight, enabling visibility of X and V from about 10 PM to 2 AM. In places like Sydney, the daytime blocks visibility as the first quarter falls around 3 PM local time.

For the best chance to view the Moon’s captivating X’s and V’s, ensure you’re gazing at a waxing moon during optimal hours, preferably when it’s high in the night sky. Tools like Stellarium can help you track the Moon’s visibility on specific dates.

Mark your calendars for upcoming first quarter events on February 24th, March 25th, and April 24th-25th. If you’re in the UK, you might want to target March 25th as it aligns well with evening visibility around 7 PM local time.

Understanding the intricacies that must align for the Moon’s X and V to appear, I feel fortunate to have captured my first lunar photo during such a special moment.

NASA Moves Moon Rocket to Launch Pad for Upcoming Astronaut Mission

NASA is set to roll out a massive 322-foot-tall rocket towards its launch pad this Saturday, a crucial milestone in the preparation for its highly anticipated Artemis II mission, which aims to send four astronauts around the moon.

The Space Launch System (SLS) rocket will transport the Orion capsule containing the astronauts, beginning its slow four-mile trek from NASA’s Vehicle Assembly Building to the launch pad at Kennedy Space Center in Florida at 7 a.m. ET. Viewers can catch the event, known as the “rollout,” live on NASA’s YouTube channel.

This event marks the beginning of essential tests and rehearsals that will pave the way for the first manned flight to the moon in over 50 years. Artemis II is tentatively scheduled for launch between February 6 and 11, with additional windows available in March and April.

The rollout is a critical phase for mission managers as they assess the rocket’s health and safety prior to setting a formal launch date.

“These are the kind of days we are living in,” stated John Honeycutt, chairman of the Artemis II mission management team, during a recent press conference.

Artemis II will feature a crew of four, including NASA astronauts Reed Wiseman, Victor Glover, and Christina Koch, along with Canadian astronaut Jeremy Hansen. They are scheduled to spend 10 days in space, initially orbiting Earth before heading into lunar orbit.

The deployment process is expected to take up to 12 hours. The Crawler Transporter, a giant mobile platform, will carry the 11 million-pound Artemis II rocket to NASA’s historic launch pad 39B, previously used in the Apollo and Space Shuttle programs.

NASA has indicated that the stacked rocket will move forward at a cautious pace, approximately 1 mile per hour.

Upon reaching the launch pad, preparations will begin for the essential launch day walkthrough, known as a wet dress rehearsal. This procedure includes refueling the rocket and conducting all standard protocols leading up to the T-29 second mark on the countdown, as detailed by Artemis launch director Charlie Blackwell Thompson.

“Launch day will closely mirror a wet dress rehearsal,” she explained. “The two main differences are sending our team to the pads and proceeding past the 29-second mark.”

This wet dress rehearsal serves as an opportunity for mission managers to evaluate the rocket’s systems in a real-world context while allowing engineers to identify any potential fuel leaks or technical issues.

If any problems arise, the rocket will be returned to the Vehicle Assembly Building for necessary repairs. However, if everything proceeds smoothly, NASA may soon announce a target launch date.

The Artemis II mission will serve as the most rigorous test yet for the Space Launch System rocket and Orion spacecraft, marking the first time the system will carry a crew.

During their time in the Orion capsule, astronauts will test the spacecraft’s docking capabilities and life support systems while in orbit around both Earth and the Moon.

Success in this mission will establish a foundation for Artemis III, slated for 2027, aiming to land astronauts near the moon’s south pole.

Returning to the moon has emerged as a priority for the U.S. government, particularly amid a new space race with China, which aims to land its own astronauts on the Moon by 2030.

Probability of Asteroid 2024 YR4 Impacting the Moon May Increase to 30%

SEI 273826369

Asteroid 2024 YR4 might strike the moon

Mark Garlick/Science Photo Library

Astronomers have a limited timeframe to determine if they will intervene to stop asteroid 2024 YR4 from colliding with the moon in 2032. A brief observation period utilizing the James Webb Space Telescope is set to commence in February, as new findings indicate that the potential for impact is rising to over 30%, posing a significant threat to satellites and future lunar infrastructures.

Discovered late last year, 2024 YR4 quickly emerged as the most probable asteroid to strike Earth. The worst-case scenario initially estimated a collision probability of 1 in 32 for 2032. However, further observations have nearly eliminated the chance of an Earth impact, leaving a 4 percent possibility of a collision with the moon, which could endanger numerous vital satellites orbiting Earth due to debris.

Despite the considerable risk associated with this asteroid, space agencies have yet to take action, although NASA researchers are exploring potential deflection strategies, such as deploying a nuclear charge near the asteroid.

The asteroid has recently moved out of range for Earth’s telescopes, limiting astronomers’ ability to obtain further data on its orbit until it reappears in 2028, which may not allow enough time to execute a deflection mission.

Fortunately, the James Webb Space Telescope (JWST) anticipates a brief operational window to observe the asteroid in February 2026 and again in April 2024, offering a critical opportunity to plan a deflection mission. Andrew Rivkin from Johns Hopkins University in Maryland remarked, “By 2028, it will be in close proximity, so capturing data in early 2026 grants us additional time.”

This advantageous positioning will enable JWST to observe 2024 YR4, which follows a distinct orbit around Earth, undetectable by other ground-based telescopes, but the observation will still be challenging, as the asteroid is expected to be dim, even for JWST’s highly sensitive instruments. There will be two narrow windows for observation on February 18th and 26th.

Rivkin and his team computed how new data regarding the asteroid’s positions and velocities could alter the existing understanding based on these observations. Their findings indicate an 80% likelihood of reducing the probability of a lunar impact to under 1%, while there is a 5% chance that the risk could increase to 30% or higher. JWST should have a chance to repeat these observations in 2027, but this will provide less time for decision-making, according to Rivkin.

Nonetheless, it remains uncertain whether space agencies would opt to plan missions in the event of increased risks. “The question of whether planetary defense extends to the moon is entirely new, and different agencies may have varied responses,” Rivkin noted. “If a company operates many satellites, they might advocate for a particular course of action.”

Richard Moisle from the European Space Agency indicated that while the current budget does not allocate for deflection or reconnaissance missions regarding the asteroid, they will reevaluate if next year’s observations indicate a heightened risk of collision. “We chose to delay our decision until next year to allow for a thorough evaluation of our options,” Moisle stated.

Astronomers Unveil Moon Concealed in Earth’s Shadow

Astronomers have identified a peculiar “moon” that casts a shadow on Earth as it navigates through space. Dubbed quasi-moons, these entities don’t orbit our planet in a traditional manner, yet they maintain proximity as they travel around the sun.

According to a new study published in the American Astronomical Society Research Notes, this space rock may have been a companion to Earth for as long as 60 years.

The object, identified as 2025 PN7, is small enough that it might have evaded earlier detections. While its exact dimensions remain uncertain, researchers estimate it to be around 30 meters (98 feet) in diameter—approximately the wingspan of a typical short-haul airliner—making it the tiniest known quasi-moon associated with Earth.







“With rapid technological progress, we’re identifying near-Earth objects faster than ever,” said Dr. Darren Baskill, an astronomy lecturer at the University of Sussex, in BBC Science Focus. “The sensitivity of digital cameras has improved, allowing us to detect these faint objects, and computers can effectively process vast data sets.”

At its closest approach, this object comes within 300,000 km (186,400 miles) of Earth. Usually, it remains about 384,000 km (238,600 miles) away, but its horseshoe-shaped orbit can take it as far as 297 million km (185 million miles) from our planet.

Consequently, it’s only detectable when nearby, as occurred in August 2025, when researchers from Spain’s Complutense University of Madrid spotted it from the PanSTARRS Observatory in Hawaii.

Upon reviewing historical records, scientists identified it as a potential Earth companion for decades.

“The primary question is, where did 2025 PN7 originate?” Baskill noted. “At its closest, 2025 PN7 will be roughly the same distance from Earth as the Moon, providing insights into the Moon’s possible origin.

“Another clue can be observed on a clear night: the Moon is full of craters. Each impact casts debris into the atmosphere, and some material may escape the Moon’s gravity and be launched into space.”

Another hypothesis suggests that the space rock originated in the asteroid belt, but Baskill states, “It’s challenging to gather sufficient light from such a moving object to determine its chemical composition and origin.”

He further added, “Astronomers must be patient and wait to observe PN7 when it’s at its brightest, closest to Earth.”

2025 PN7 is just one of seven quasi-satellites currently orbiting near Earth. The other is the space rock Kamooarewa, which is the target of China’s Tianwen-2 mission. Launched in May 2025, Tianwen-2 aims to collect samples from asteroids to understand more about Earth’s origins and asteroid formation.

“These near-Earth objects, due to their occasional close passes, might become prime targets for the inaugural mining operations beyond Earth, or even enter Earth’s atmosphere,” Baskill remarked.

PN7 will remain in existence until 2085 when it will be pulled from orbit by gravitational forces.

Saturn’s Moon Titan Could Harbor an Unforeseen Blend of Hydrogen Cyanide and Hydrocarbons

Titan serves as an intriguing subject for in-depth investigations of organic chemistry under unusual conditions. This Saturnian moon is abundant in nonpolar hydrocarbons like ethane and methane, alongside hydrogen cyanide (HCN), a highly relevant small polar molecule in prebiotic chemistry. Recent studies show that these notably polar compounds can mix at low temperatures, creating structures that challenge traditional chemical theories.

Hydrogen cyanide is commonly found in the astrochemical landscape and has been detected in numerous celestial bodies, including the interstellar medium, comets, planets, moons, and dwarf planets.

This molecule ranks as the second most prevalent product anticipated from Titan’s atmospheric chemistry.

Dr. Martin Rahm, a researcher from Chalmers University of Technology, stated: “These remarkable discoveries enhance our understanding of something vast—a moon comparable in size to Mercury.”

In laboratory experiments, Rahm and his team combined hydrogen cyanide with methane and ethane at temperatures as low as 90 K (around -180 degrees Celsius).

At this temperature, hydrogen cyanide forms crystals, while methane and ethane exist as liquids.

Using laser spectroscopy to analyze these mixtures at an atomic level, researchers found that while the molecules remained intact, changes were still occurring.

To uncover what was happening, they conducted extensive computer simulations to explore thousands of potential molecular arrangements in the solid phase.

Ultimately, they discovered that the hydrocarbons infiltrated the hydrogen cyanide crystal lattice, leading to the formation of a stable new structure termed a cocrystal.

“The identification of unexpected interactions between these substances may influence our understanding of Titan’s geology and unique features such as lakes, oceans, and sand dunes,” Dr. Rahm explained.

“Moreover, hydrogen cyanide could be crucial in the abiotic synthesis of some life-building blocks, like amino acids for proteins and nucleobases for genetic material.”

“Consequently, our research offers valuable insights into the pre-emergent chemistry of life and the potential for life to evolve in extreme environments.”

Why NASA’s Moon Return Aspirations Hang on SpaceX Before China Beats Them There

Intricate and sophisticated sequences depend on several untested technologies. A crucial aspect is the refueling of starships in space. Dreyer noted that it remains uncertain how many launches will be required to supply the necessary fuel, but they must occur rapidly.

“It might take between 12 and 20 refueling missions within a month to replenish Starship’s tanks with enough fuel for a mission to the moon and back,” he stated. “Such a scenario has never been realized.”

Refueling only in space would necessitate a “significant advancement” from Starship’s current capabilities, he remarked.

“This poses a tremendous challenge,” Dreyer emphasized. “Without these advancements, our lunar aspirations won’t be achievable.”

The Starship lander is projected to stand approximately 150 feet taller than the rugged, spider-like lunar lander NASA utilized during the Apollo missions. Such a taller design could enable Starship to transport more passengers and cargo; however, it may also be less stable than the Apollo spacecraft.

Nevertheless, Dreyer argued that it wouldn’t have been practical for NASA to depend on outdated technology, especially considering financial constraints. A single Saturn V rocket launch from the Apollo era costs around $2 billion today. In contrast, SpaceX aims to develop Starship as fully reusable, which could lower costs and speed up launch times.

The next phase for the company involves revealing an upgraded Starship prototype. This model is approximately five feet taller and incorporates an enhanced docking mechanism, increased energy storage, and software improvements to facilitate long-duration flights.

This new version will be employed for Starship’s inaugural orbital flight, testing essential SpaceX procedures such as fuel transfer and payload transportation into space, as per SpaceX officials. I discussed this in my previous post following Monday’s test.

Future missions, like this week’s, will also be under scrutiny as China moves toward its 2030 objectives.

“Four years is a short time frame in space,” Dreyer remarked. “These endeavors are exceptionally complex and challenging because the universe is perpetually testing you.”

Apollo 17 Moon Samples Reveal Uncommon Sulfur, New Analysis Indicates

The prevailing theory regarding the origin of the Moon suggests it formed from a colossal impact event involving Earth and a body known as Theia. The degree to which materials from these two celestial objects mixed during this event is still debated. Poor mixing may leave traces of the original atomic and/or Theia composition. The sulfur isotopic makeup of the primordial materials that survived the impact can help establish parameters concerning the chemistry of the early solar nebula, the sulfur distribution in the early solar system, and the efficiency of mixing during this significant lunar impact event. In a recent study, researchers from Brown University and other institutions present intriguing sulfur isotope data derived from lunar rocks collected from the Taurus Littrow region during Apollo 17. Their analysis reveals that the volcanic material in the samples is significantly depleted in sulfur-33. This depletion sharply contrasts with sulfur isotope ratios found on Earth, suggesting the likelihood of:

Some elements possess distinct “fingerprints” through specific isotopic ratios, revealing slight variations in atomic weights.

If two rocks share the same isotopic fingerprint, it strongly indicates a common origin.

In terms of the Moon and Earth, researchers have identified general similarities in the oxygen isotopes of both bodies.

Dr. James Dottin, a researcher from Brown University, stated:

“Previously, it was assumed that the Moon’s mantle shared the same sulfur isotope composition as Earth.”

“This was the anticipated outcome when we examined these samples, yet we observed values markedly different from those found on Earth.”

The sample under investigation was sourced from a double-drive tube—a hollow metal cylinder driven approximately 60 cm into the lunar soil by Apollo 17 astronauts Gene Cernan and Harrison Schmidt.

Upon returning to Earth, NASA secured the tube in a helium chamber to preserve the sample for future studies under the Apollo Next Generation Sample Analysis (ANGSA) program.

In recent years, NASA has begun to make ANGSA samples accessible to academic researchers via a competitive application process.

Dr. Dottin and his team chose secondary ion mass spectrometry for sulfur isotopic analysis. This precise analytical method did not exist in 1972 when the samples were initially returned to Earth.

For their research, they targeted specific samples from drive tubes believed to originate from mantle-derived volcanic rocks.

“There are two possible explanations for the anomalous sulfur,” Dr. Dottin explained.

They may represent remnants of chemical processes that took place during the Moon’s early history.

When sulfur interacts with ultraviolet light in a thin atmosphere, a diminished sulfur-33 ratio can be observed.

It is theorized that the Moon had a transient atmosphere in its early history, which could have facilitated such photochemical reactions.

If this is indeed the case, it would have interesting implications for the Moon’s evolutionary history.

“This offers evidence of ancient material transfer from the lunar surface into the mantle,” Dr. Dottin said.

“On Earth, we rely on plate tectonics for this process, but the Moon lacks such tectonic activity.”

“Thus, the idea of some form of exchange mechanism on the early Moon is thrilling.”

Alternatively, the unusual sulfur signatures could be remnants from the Moon’s formation itself.

The prevailing theory states that a Mars-sized object named Theia collided with Earth early on, with debris from that impact eventually forming the Moon.

The sulfur signatures from Theia differ significantly from those of Earth, and these differences may be reflected in the Moon’s mantle.

This study does not definitively resolve which explanation is accurate.

“Investigating sulfur isotopes from Mars and other celestial bodies may someday provide insights,” Dr. Dottin remarked.

“Ultimately, a better understanding of isotopic distributions will enhance our comprehension of solar system formation.”

New Research Indicates the Far Side of the Moon is Colder than Its Near Side

The stark differences in proximity and width between the moon’s near and far sides, along with their topography, volcanism, and crustal structures, offer crucial insights into the moon’s formation and evolution. However, investigations into the mechanisms behind this hemispherical asymmetry have been constrained by the absence of far-side samples. A recent study revealed fragments of rock and soil collected by China’s Chang’e 6 spacecraft from a large crater on the moon last year. Researchers confirmed that these rock samples are approximately 2.8 billion years old, analyzed the chemical composition of the minerals, and estimated that they were formed from lava deep within the moon at temperatures around 1,100 degrees Celsius. Survey results were published in the journal Natural Earth Science.

“The near and far sides of the moon differ significantly, both on the surface and potentially in their internal structures,” said Professor Yang Lee, a researcher at the University of London.

“This is one of the moon’s great mysteries. We refer to it as the two-sided moon. While variations in temperature between the near and far sides have long been theorized, our research presents the first evidence derived from actual samples.”

“These discoveries bring us closer to understanding the moon’s dual nature,” stated PhD candidate Xuelin Zhu from Peking University.

“They indicate that the disparities between the two sides extend beyond the surface, reaching deep within the moon.”

In this research, the authors examined 300 grams of lunar soil assigned to the Beijing Institute of Uranium Geology.

“This sample represents the first collection by the Chang’e 6 mission from across the moon,” commented Dr. Sheng, a researcher at the same institute.

The researchers found the samples were primarily composed of basalt particles and utilized electron probes to map specific areas of the sample, determining their composition.

They analyzed variations in lead isotopes dating back 2.8 billion years.

Several techniques were employed to estimate the sample temperatures at different stages in the moon’s past.

The first method involved analyzing mineral composition and comparing it with computer simulations to estimate the formation temperatures of the rocks.

This was juxtaposed with similar estimates for rocks from the near side, revealing a temperature difference of approximately 100 degrees Celsius.

The second technique delved further into the sample’s history, inferring from its chemical composition to ascertain the heat of the “parent rock” and comparing it with estimates of lunar samples obtained during the Apollo missions.

Once again, a Celsius difference of about 100 degrees was identified.

Due to the limited samples returned, they estimated the parent rock temperature using satellite data from the Chang’e landing sites on both sides, comparing this with similar data from nearby areas, which revealed a difference of 70 degrees Celsius.

On the moon, thermogenic elements like uranium, thorium, and potassium are often found alongside phosphorus and rare earth elements within a material referred to as KREEP (an acronym for potassium (K), rare earth element (REE), and phosphorus (P)).

The leading theory regarding the moon’s origin posits that it formed from debris resulting from a large-scale collision between Earth and a Mars-sized protoplanet, developing from primarily molten rock.

This magma solidified as it cooled, but KREEP elements were compatible with the forming crystals and remained within the magma for extended periods.

Scientists anticipate that KREEP material would be evenly distributed across the moon. In reality, it appears to be concentrated in the near side’s mantle.

The distribution of these elements may explain why the near side exhibited more volcanic activity.

While the current mantle temperatures on the far and near sides of the moon remain unknown due to this study, the temperature imbalances are likely to persist for a considerable duration, as the moon cools very slowly since its formation from a catastrophic impact.

Scientists aim to provide definitive answers to these questions in ongoing research.

Should We Target the Asteroid Heading Toward the Moon as Our Core Initiative?

What action should humanity take if an asteroid is heading toward the moon? Why not attempt to divert these celestial bodies before they collide? Should we neutralize it with a nuclear explosion?

These queries are examined in a recent paper authored by more than a dozen researchers, including NASA scientists. These scenarios aren’t merely theoretical: the asteroid known as 2024 YR4 is estimated to have a 4% chance of impacting the moon in 2032.

Such collisions could “spike levels of background radiation up to 1,000 times higher in just a few days, posing threats to astronauts and spacecraft in low-Earth orbit,” the researchers noted in their paper. The preprint on arXiv was published on September 15th but has yet to undergo peer review.

To prevent a potentially hazardous debris field, one approach is to use nuclear energy to neutralize the asteroid or, as scientists term it, create a “robust mess” before it reaches the moon.

Cue references from the “Armageddon” movie.

However, this approach carries significant risks, as it has never been tested for asteroid destruction using nuclear forces.

Crucial information about asteroid 2024 YR4 remains unknown, including its mass, which is vital for determining the most effective way to “destroy” it without unintentionally creating greater problems.

“If an explosion isn’t sufficient, just create a debris field anyway,” remarked Julie Brissett, interim director of the Florida Space Institute.

Asteroid 2024 YR4 was first identified in December by Chile’s Asteroid Land Impact Trajectory Store Alt System Station. NASA estimates it could be up to 220 feet in diameter, large enough to be categorized as a “city killer,” since it could severely damage an urban area or region on Earth.

Experts initially estimated a slim chance of asteroids hitting Earth, with an impact probability of 3% predicted earlier this year. However, subsequent analyses ruled out collisions with our planet.

Given that Earth appears to be safe, asteroid 2024 YR4 is considered to have an estimated 4.3% chance of impacting the moon.

The authors of a recent paper suggested launching a reconnaissance mission to study the asteroid and then developing an explosive device before deploying it for a space lock.

Alternatively, if a nuclear detonation is deemed too extreme for destruction, researchers will provide detailed strategies for steering the asteroid off course.

NASA has relevant experience; in 2022, its DART probe successfully altered its orbit by crashing into a small asteroid called Dimorphos. This test occurred 6.8 million miles from Earth, successfully redirecting Dimorphos and reducing its orbital period by 33 minutes, according to NASA.

However, for deflection efforts to succeed, Brissett noted that it’s crucial to ascertain the mass of asteroid 2024 YR4.

In response to an NBC News inquiry regarding NASA’s recent paper, Kelly Fast, the agency’s Planetary Defense Officer, stated that there are currently no plans to deflect the asteroid or intervene in its course.

Nevertheless, she indicated that a study is planned for early next year using the James Webb Space Telescope, aiming to yield insights into its trajectory.

“If we observe it, additional data could enhance our understanding of the asteroid’s position in December 2032,” Fast mentioned, “possibly reducing the impact probability to 0%.”

Even if missions, such as those discussed in the paper, can be executed, there are political dynamics to consider.

Currently, no astronauts or long-term habitats exist on the moon, though this may change. China, for instance, intends to send astronauts to the moon by 2030 and has discussed establishing a nuclear power plant there to support lunar bases in partnership with Russia.

The U.S. plans to conduct regular missions to the moon before NASA eventually targets Mars, but future missions and objectives remain uncertain due to notable budget cuts exceeding $6 billion in the NASA budget plan proposed by President Trump.

The use of nuclear devices in space could escalate tensions among the U.S., China, and other space-faring nations, potentially leading to disputes over which countries and agencies would spearhead or contribute to such projects, noted Brissett.

“It’s likely a country with the technical capability to do that,” she said, “narrowing it down to three or four, but the question remains: do they want to collaborate?”

Moon Missions May Introduce Harmful Earth Microbes to the Lunar Surface

Satellite images of the moon’s Antarctic region and Schrödinger Basin

The moon might endure far longer than previously thought, raising the concern of contaminating its surface before future lunar missions take place.

Space missions are required to follow the “Planetary Protection” policy, ensuring that microorganisms from Earth do not contaminate other celestial bodies.

Unlike Earth, where protective measures such as the atmosphere and magnetic fields exist, the moon’s surface faces intense high-energy particles from space, extreme temperatures, and harmful ultraviolet rays from the sun, making it a harsh habitat for surviving organisms.

As a result, many astronomers classify the moon’s surface as inherently barren. The Space Research Committee ranks it in the second lowest category of planetary protection, alongside Venus and comets, indicating that “spacecraft-mediated contamination could compromise investigations.”

Nonetheless, new findings from Stefano Bertone of the NASA Goddard Space Flight Center and colleagues indicate that in certain areas near the moon’s poles, which are set to be visited by NASA’s upcoming Artemis Mission, life might survive for several days, possibly over a week. This heightens the risk of contaminating these zones and generating misleading results in the search for extraterrestrial life.

“We’re returning to the moon, leaving traces behind. We need to study what kinds of traces we’re leaving and how to minimize them,” Bertone remarked at the Europlanet Science Congress (EPSC) in Helsinki, Finland, on September 12th.

Bertone and his team discovered five microbial species that show resilience to harsh environments, including black mold (Aspergillus niger) and bacteria Staphylococcus aureus and Bacillus subtilis. They assessed how much ultraviolet radiation these organisms could withstand in their laboratory. They compiled data concerning UV levels on the moon’s surface, sunlight exposure, and temperature fluctuations, which allowed them to create a map indicating where these five organisms could survive for at least one day.

All living organisms can endure well-lit areas outside the permanently shadowed regions where sunlight and ultraviolet rays are absent, making these bright zones prime candidates for lunar exploration. The black mold exhibited the highest resilience, surviving in extensive areas for up to seven days.

“This is a significant study that clearly shows if there’s a risk of contamination, then certain actions need to be taken. However, we must also recognize that these actions have economic implications,” stated Stas Barabash from the Swedish Institute of Astrophysics. For instance, space agencies might decide that equipment requires more thorough sterilization, which could increase mission costs.

The Moon Could Soon Be the Site of Humanity’s Wildest Experiments

What would occur if a Super Collider encircled the moon? Surprisingly, scientists and engineers are intrigued by the concept of a Super Collider of the Moon.

This type of machine operates similarly to the Large Hadron Collider (LHC) at CERN near Geneva, which is the world’s most extensive and highest-energy particle accelerator. These “atomic smashers” generate two beams of particles that travel in opposing directions through ultra-high navigational rings.

A robust superconducting electromagnet propels the beams to nearly the speed of light. When these beams collide with detector instruments, they produce a cascade of additional particles that can be measured and analyzed.

The greater the energy of the particles involved, the more substantial the mass of the collider’s “products”.

Numerous inquiries in contemporary particle physics necessitate exploring this high mass parameter space. Consequently, physicists are eager to construct larger, more powerful colliders. The moon, in this case, serves as an ideal location.

One study from 2022 explored the concept of atomic smashers surrounding the moon, spanning approximately 11,000 km (6,835 miles). This collider could operate at 1,000 times the energy of the LHC, enabling physicists to search for new particles and phenomena.

While it is challenging to foresee the discoveries that such an enormous accelerator might yield, scientists hope it could provide insights into the evolution of the universe and its colossal structures.

But why construct these machines on the moon instead of Earth? Essentially, it boils down to real estate. Colliders exceeding 10,000 km (6,214 miles) in diameter present numerous geological, technical, and political challenges on our planet.

Conversely, the moon offers several advantages. Building a circular tunnel beneath its surface and maintaining the essential superconducting ring would be easier (and more cost-effective).

Additionally, the moon is more geologically stable than Earth and has a plentiful supply of solar energy.

Engineers estimate that establishing a Super Collider on the moon would take over 20 years, assuming human presence is established there. Thus, the prospect of a “Mega-Collider” materializing in this century appears slim.

Junho Analyzes the Ultraviolet Satellite Footprint of Jupiter’s Moon Callisto

Jupiter showcases the most brilliant and magnificent auroras in the solar system. Near its poles, these shimmering lights provide insight into how its moons and planets engage with the solar wind propelled by Jupiter’s magnetic field. In contrast to Earth’s auroras, the largest of Jupiter’s moons generates its own unique auroral signature within the planet’s atmosphere. The auroras linked to these moons, referred to as satellite footprints, illustrate the interactions of each moon with its immediate spatial environment.

Junho captures the mark on Jupiter in all four Galilean Moons. The aurora associated with each are labelled IO, EUR (europa), Gan (for Ganymede), and Cal (for Callisto). Image credits: NASA/JPL-CALTECH/SWRI/UVS TEAM/MSSS/GILL/Jónsson/Perry/Hue/Rabia.

Prior to NASA’s Juno Mission, three of Jupiter’s largest moons—Io, Europa, and Ganymede—were known to produce distinct auroral signatures.

However, the farthest moon, Callisto, remained an enigma.

Despite numerous attempts using the NASA/ESA Hubble Space Telescope, Callisto’s footprints were faint and difficult to detect, often overshadowed by the bright Main Auroral Oval, the region where auroras are prominently observed.

NASA’s Juno Mission has been in orbit around Jupiter since 2016, providing an unprecedented close-up view of these polar light displays.

To capture Callisto’s footprint, the main auroral oval needs to be bypassed while imaging the polar regions.

Additionally, to incorporate it into the suite of instruments analyzing the fields and particles within Juno’s payload, the spacecraft’s path must cross the magnetic field line linking Callisto to Jupiter.

These necessary conditions coincidentally occurred during Juno’s 22nd orbit of the giant planet in September 2019, leading to the discovery of Callisto’s Auroral Footprint and offering samples of the magnetic fields related to particle populations, electromagnetic waves, and interactions.

Jupiter’s magnetic field extends far beyond its largest moon, forming a vast area (magnetosphere) where solar wind flows from the sun.

Just like solar storms on Earth can push the Northern Lights to lower latitudes, Jupiter’s auroras are also influenced by solar activity.

In September 2019, a significant and dense solar stream impacted Jupiter’s magnetosphere, causing the auroral ellipse to shift towards the equator, revealing a faint yet distinct feature associated with Callisto.

This finding confirms that all four Galilean moons leave their imprint on Jupiter’s atmosphere, with Callisto’s footprints closely resembling those of its inner companions, thus completing the family portrait marked by Galilean Moon Auroras.

“Our observations substantiate the electrodynamic coupling between Callisto and Jupiter,” stated Dr. Jonas Lavia, a researcher at Astrophysics-Planetology and CNRS, along with colleagues.

“This combination will undergo further examination by NASA’s JUICE mission, which was successfully launched in April 2023. This mission will facilitate repeated explorations of Callisto and its local environment, enhancing our understanding of the magnetospheric interactions between Callisto and Jupiter.”

“Reported in situ and remote observations complete the family portrait of the footprints of Galilean Moon Auroras, addressing a long-standing question about whether Callisto’s electromagnetic interactions differ fundamentally from the inner three Galilean satellites.”

“The observed similarities in both the auroral structure and the in situ characteristics of electrons point to the universal physical mechanisms at play in the magnetospheric interaction of moons and stars, akin to other binary systems accessible within the solar system and beyond.”

The team’s paper was published this week in the journal Nature Communications.

Get Ready for the Stunning Harvest Blood Moon on September 7th!

3ABDR5N Total Lunar Eclipse, blood moon with tree silhouette in Pennsylvania, USA

“Find the moon and watch it darken and redden…”

JG Photo/Alamy

My perspective on the moon has changed in the past year, especially since I gave birth during the harvest month, coinciding with the full moon.

In those early months with my son, time felt peculiar. The boundary between day and night blurred. Yet, the lunar cycle marked the passage of time. Each full moon signified that another 29.5 days had gone by and reminded me that my son was growing month by month.

<p>The upcoming full moon will carry special significance, as it coincides with a total lunar eclipse on September 7th, 2025.</p>
<p>This spectacular event will be visible to many around the globe, including parts of Europe, Asia, Africa, Australia, and South America. In my location in the UK, the moon will emerge from below the horizon around 20 minutes later, at approximately 7:30 PM, and will remain visible until the eclipse concludes.</p>
<p>As I mentioned, the full moon occurs every 29.5 days. During this phase, our planet is positioned between the sun and the moon, allowing the moon to fully reflect sunlight towards us.</p>
<section></section>
<p>However, because the moon's orbit is slightly tilted relative to Earth's orbit around the sun, these celestial bodies don’t always align perfectly (a phenomenon known as Syzygy).</p>
<span class="js-content-prompt-opportunity"/>
<p>When syzygy happens during the new moon, a solar eclipse occurs. Conversely, if it happens during the full moon, we witness a total lunar eclipse.</p>
<p>During this event, the moon will enter Earth's shadow, which is why it appears dark and red. The only light that reaches the moon's surface and is reflected back to us has passed through Earth's atmosphere, scattering most wavelengths except for the reds.</p>
<p>To discover the best times to view the lunar eclipse and what you can see from your location, check out the <a href="https://www.timeanddate.com/eclipse/lunar/2025-september-7">Interactive Solar Eclipse Map</a>.</p>

<p>Unlike solar eclipses, no special equipment is necessary for viewing the lunar eclipse—just a clear sky. Once you know when to look, find the moon and watch it transition to a dark, red hue (as shown in the photo). If you're in the UK, you’ll find the moon positioned on the eastern horizon, so make sure to find a spot with a clear view to the east.</p>
<p>This full moon, occurring just before the autumn equinox, is often referred to as the harvest blood moon due to the reddish color it takes on during the eclipse.</p>
<p>I’m not certain how old he has to be to appreciate it, but I plan to take my son outside to witness this beautiful lunar sight that coincides with his birth in the harvest month.</p>

Is the Giant Moon Telescope Humanity’s Best Hope for Discovering Aliens?

“In 2050, the first 100m diameter telescope took shape in a crater on the moon.”

Vladimir Vasyansky/NASA

The Allsea eyes, operational since the 2070s, were the largest and most powerful optical systems ever constructed. Comprising eight telescopes dispersed across the lunar expanse, each equipped with a 100-meter mirror, the collective aperture of this composite telescope spanned the entire lunar surface, enabling exceptional imaging capabilities.

This marked the first occasion we could observe the “first light,” indicating the birth of the universe’s first star. We also captured details of distant exoplanet surfaces across great expanses of time.

In 2020, numerous proposals emerged for these ambitious, next-generation telescopes; however, the technological feasibility for large-scale space projects was limited at that time. By the 2050s, lunar transport became routine and economically viable, paving the way for lunar construction.

An earlier proposal from 2020 focused on what was termed Finally, a large telescope (ULT), with a mirror measuring 100 meters, came to fruition.

ULT utilized liquid mirrors instead of traditional glass. These liquids were more cost-effective to transport to the moon and could be molded into completely reflective surfaces. Given the moon’s gravity, constructing larger mirrors that exceed those on Earth became practical. For comparison, the James Webb Space Telescope, operational in the 2020s, features a 6.5-meter mirror.

While the lunar single telescope was powerful, it lacked the resolution to distinguish the detailed features of exoplanet bodies. Nonetheless, astronomers focused on expanding ULT’s capabilities.

A clever technique used in radio telescopes to enhance their range, Very Long Baseline Interferometry (VLBI), proved suitable for optical systems as well. In 2017, the Event Horizon Telescope Collaboration employed VLBI to capture the first image of a supermassive black hole at the center of our galaxy by merging inputs from eight Earth-based telescopes to amplify the effective telescope size.

In 2025, scientists spearheaded by Zixin Huang at the Engineering Quantum Systems Center at Macquarie University, Australia, proposed using VLBI for optical telescopes. Although technical, political, and financial barriers prolonged development, the advent of the first 100-meter diameter telescope in lunar craters by 2050 led to serious initiatives for constructing a lunar-sized optical telescope.


The telescope on the moon dates back 13 billion years and photographs the first generation of high-mass stars.

By 2075, an additional seven telescopes were established on the lunar surface, linking to form an effective aperture equivalent to a 3000 km mirror.

In the mid-2020s, the James Webb Telescope revisited the past to observe the formation of the universe’s first galaxy. Now, through the combined observations, the enigmatic Population III stars have been unveiled. Stars are categorized into different groups; Population I contains recent stars abundant in heavy elements, Population II includes older stars with lower metal content, while Population III consists of the universe’s earliest stars formed post-Big Bang, characterized by minimal metallic content. The Big Bang primarily produced hydrogen and helium, with mere traces of lithium and beryllium. All heavier elements had to be synthesized in stars. The combined observations have looked back 13 billion years and documented the high-mass first-generation stars, including one blue giant star, 100,000 times the mass of the sun, dubbed Zixin-1 in honor of the astronomer who significantly contributed to the development of optical VLBI.

The moon-sized telescope concept has been referred to by various names over the years. Initially proposed in 2008 by a team from the University of Arizona, the lunar liquid spraying telescope eventually evolved into a larger project in 2020. To escape the possibly uninspired public names like Moony McMoonface, the term “Allsea Eyes” was officially adopted. The project is now affectionately dubbed Sauron: Super-Accessible Ultra-Resolution Optical Network.

The facility has enabled unprecedented imaging of black holes, but its primary objective was to determine if humanity is alone in the universe. The observations made of the exoplanet Gliese 667cc indicated the potential for alien civilizations to have developed in our cosmic neighborhood, particularly within the Trappist-1 system, about 22 light-years away. Despite debates surrounding the costs of constructing Sauron, they never gained significant traction.

Psyche Embodies the Essence of Earth and Moon

On July 20th and July 23rd, 2025, NASA’s Psyche spacecraft captured images of Earth and the Moon from a distance of approximately 290 million km (180 million miles). The spacecraft’s twin cameras took several long exposure photographs, showcasing the two celestial bodies as glimmering dots in the sunlight against the backdrop of the Aries constellation.

Psyche is NASA’s mission aimed at studying metal-rich asteroids located in the main asteroid belt between Mars and Jupiter.

This mission marks NASA’s first endeavor to examine asteroids composed primarily of metal rather than rock and ice.

Psyche launched on October 13, 2023, at 10:19 AM aboard a SpaceX Falcon Heavy rocket from the Kennedy Space Center.

By August 2029, the spacecraft will begin its exploration of asteroids that scientists believe are remnants of planetary cores due to their high metal content.

“The multispectral imager equipment features a pair of identical cameras equipped with filters and telescope lenses designed to capture the asteroid’s surface using light across various wavelengths,” stated a member of the mission’s science team.

“The color and shape of the asteroid’s spectrum can provide insights into its composition.”

“For instance, the Moon and the large asteroid Vesta exhibit similar spectral ‘bumps and wiggles’ that scientists could potentially identify in Psyche.”

Researchers are interested in Psyche as it may enhance our understanding of how rocky planets with metallic cores, including Earth, were formed.

When selecting targets for imaging tests and calibration, they seek bodies that reflect sunlight similarly to Psyche.

This allows for comparisons with previous data obtained from telescopes or spacecraft observing these familiar spectral objects.

Earlier this year, Psyche pointed its cameras toward Jupiter and Mars for calibration purposes, and the results were successful.

To monitor changes in imager performance, researchers are also comparing data from various tests.

This ensures that when the spacecraft enters orbit around Psyche, the equipment will function as anticipated.

“We’re thrilled about the opportunity to further our understanding through our efforts,” remarked Dr. Jim Bell, Psyche Imager Instrument Lead at Arizona State University.

“We gather ‘trading cards’ from these distinct celestial bodies and run them through the calibration pipeline to ensure data accuracy.”

Psyche wasn’t the only instrument that underwent successful checkouts in July 2025.

The mission team also tested the spacecraft’s magnetometer and gamma-ray and neutron spectrometer, a routine procedure conducted every six months.

“Everything is operational and functioning well,” stated Dr. Bob Mas, the mission project manager at NASA’s Jet Propulsion Laboratory.

“We aim to fly by Mars in May 2026, having accomplished all planned activities for the cruise phase.”

“This flyby represents the next significant milestone for the spacecraft, utilizing the gravitational pull of Mars to assist in reaching Psyche.”

“This will be the first of two planned loops around the solar system, marking the initial 1.6 billion km (1 billion miles) journey since its launch from NASA’s Kennedy Space Center in October 2023.”

Webb Uncovers a New Moon Orbiting Uranus

Astronomers utilizing the NASA/ESA/CSA James Webb Space Telescope have identified a previously uncharted small moon, provisionally named S/2025 U 1. This discovery, made from a series of images taken on February 2, 2025, brings Uranus’s total number of moons to 29.



This Webb/nircam image illustrates S/2025 U1 along with 13 of the other 28 identified moons. Image credits: NASA/ESA/CSA/STSCI/M. El Moutamid, SWRI/M. Hedman, University of Idaho.

Situated in the outer solar system, Uranus is the seventh planet from the Sun.

This cyan ice giant, often referred to as a “lateral planet” due to its extreme axial tilt, has a thick atmosphere composed of hydrogen, helium, and methane.

The 28 moons of Uranus include five major ones: Titania, Oberon, Ambriel, Ariel, and Miranda, discovered between 1787 and 1948.

Known as “The Literary Moons,” the moons of Uranus are named after characters from the works of Shakespeare and Alexander Pope.

Astronomers estimate that Uranus’s larger moons are approximately equal parts water ice and silicate rock.

“As part of Webb’s Guest Observer program, we discovered a previously unknown satellite of the ice giant,” explained Dr. Maryame El Moutamid, a researcher at the Southwest Research Institute.

“This object is the smallest ever detected and was observed during a set of 10 long exposures captured by Webb’s near-infrared camera (NIRCAM).”

The moon, provisionally designated S/2025 U1, resides at the end of Uranus’s inner ring.

Estimated to have a diameter of only 10 km (6 miles), its reflectance (albedo) is presumed to be similar to that of other small Uranian satellites.

It is located approximately 56,250 km (35,000 miles) away from the Earth’s equatorial plane, positioned between the orbits of Ophelia and Bianca.

Ophelia has a diameter of about 43 km (13 miles), while Bianca is elongated, measuring 64 x 46 km (40 x 29 miles).

“While it’s a small moon, its discovery is significant. This is something that even NASA’s Voyager 2 spacecraft missed during its flybys nearly 40 years ago,” Dr. El Moutamid remarked.

S/2025 U1 becomes the 14th member of a complex system of small moons, circling inward among the larger moons, including Miranda, Ariel, Umbriel, Titania, and Oberon.

“Unlike other planets, Uranus possesses a remarkable number of small inner moons. The intricate interactions with its ring system indicate a chaotic history that merges the ring and lunar systems,” Dr. El Moutamid noted.

“Furthermore, this new moon’s small size and unexpected nature may lead to the discovery of even more complexities.”

Uranus: Explore Its Tiny New Moon in Just Two Hours of Walking!

Introducing the Cosmic Welcome Mat, the newest addition to our solar system.

On Tuesday, astronomers discovered a new satellite approximately the size of 90 soccer fields. This new moon was found orbiting the seventh planet from the sun, Uranus, and was initially spotted by NASA’s James Webb Space Telescope on February 2nd. It joins 28 other known moons in the busy orbit of Uranus.

The observations of Uranus made by the Webb telescope provide researchers with enhanced understanding of this enigmatic planet.

“Uranus has more small inner moons than any other planet,” stated Matthew Tiscareno, a member of the research team and senior research scientist at the SETI Institute in California. He mentioned in a statement.

Tiscareno added that the “complex interaction” between Uranus’s moons and its faint ring system hints at a tumultuous evolutionary history for the planet.

Moreover, this new moon is smaller and more surprising than the smallest previously known inner satellites, indicating there may be further complexities to uncover,” he stated in a report.

Researchers note that the new satellite is situated about 35,000 miles from the center of Uranus and maintains a nearly circular orbit.

With a diameter of just 6 miles, it can be traversed in roughly two hours at an active walking pace; however, follow-up observations are necessary to verify the moon’s size and additional characteristics.

These findings are still pending peer review.

Uranus is home to five major moons known as Miranda, Ariel, Umbriel, Titania, and Oberon. The recently discovered moon orbits among these five primary satellites, according to researchers.

All moons of Uranus are named after characters from the works of Shakespeare and Alexander Pope, as per NASA’s guidelines. The new moon is yet to be named and will require approval from the International Astronomical Union for its official designation.

“While small, this moon is a notable discovery. I didn’t even catch sight of it during the Voyager 2 mission nearly 40 years ago,” he remarked in a statement.

In 1986, the Voyager 2 spacecraft made history as the first human-made object to fly by Uranus, providing humanity’s first detailed observations of this distant planet. This encounter yielded over 7,000 images and led to the discovery of two new rings and 11 new moons around Uranus.

While the latest moon’s size might have been too small for the Voyager 2 camera to detect, the advanced instruments aboard the Webb telescope are expected to reveal more about Uranus and its system.

“Looking ahead, the discovery of this moon exemplifies how modern astronomy builds upon the legacy of missions like Voyager 2,” El Moutamid stated. “Now, almost 40 years later, the James Webb Space Telescope is pushing those boundaries even further.”

Newly Discovered Moon Reveals Uranus Has the Smallest Orbit of Its Kind

Astronomers have identified a new moon nestled among the 28 others near Uranus.

NASA, ESA, CSA, STSCI, M. ELMOU

A recently discovered, faint moon orbits Uranus, bringing its total count to 29. Several of the other moons of this gas giant bear names from the works of William Shakespeare, and there are discussions among scientists about which character will inspire the new moon’s name.

The moon was uncovered by a team led by Maryame El Moutamid from the Southwest Research Institute in Colorado, utilizing 10 long-exposure infrared images captured by NASA’s James Webb Space Telescope (JWST) on February 2 this year.

For now, the moon is temporarily designated as S/2025 U 1. However, it is likely to receive a name aligned with the tradition of naming Uranus’ moons after characters from Shakespeare’s plays, a convention established since the discovery of Titania and Oberon, the planet’s first two moons, in 1787.

All proposed names for newly discovered moons must receive approval from the International Astronomical Union (IAU), the authoritative body responsible for assigning names and designations to celestial objects. Mark Showalter from the Seti Institute, who is part of the research team and an avid theater enthusiast, mentioned that while there hasn’t been any discussion on candidates yet, it’s certainly an intriguing proposition.

Showalter described the challenge of detecting such a small, dim moon, comparing it to “trying to see a fly while staring directly at the headlights of a car.” He expressed admiration for the James Webb telescope’s sensitivity, which far exceeds that of any telescope that has come before it.

There is optimism for more moons to be discovered around Uranus, as Showalter remarked, “We certainly haven’t completed our observations.” He believes it’s reasonable to propose that additional satellites exist, particularly those that may influence the ring system.

El Moutamid pointed out that the clarity of Uranus’ rings suggests there could be more undiscovered moons associated with their formation. “Perhaps there are more waiting to be identified,” she added. Some could be uncovered by the JWST, while others may be detected by a proposed Uranus orbiter and probe mission targeted for 2044. “There likely are many very small moons that remain invisible due to the limitations of current observational methods,” she said.

The S/2025 U1 is estimated to measure around 10 km in diameter, rendering it too small to be captured by cameras on the Voyager 2 probe, which launched in 1977 and passed Uranus in 1986, coming within around 81,500 kilometers. To date, it remains the closest encounter with Uranus by any spacecraft from Earth.

The new moon resides at the inner edge of Uranus’ rings, situated approximately 56,250 kilometers from the center of the planet’s equatorial plane, fitting between the orbits of the moons Ophelia and Bianca.

NASA oversees the JWST’s “General Observer” program, which allows researchers worldwide to propose observation targets that require one of the telescope’s advanced sensors. El Moutamid dedicated time to studying Uranus’ rings using the JWST’s Nircam Instrument (a high-resolution infrared sensor), which ultimately led to the discovery of this new moon.

Ganymede, Jupiter’s Moon, May Function as a Massive Dark Matter Detector

View of Ganymede from NASA’s Juno spacecraft

junocam/nasa/jpl-caltech/swri/msss/kalleheikki kannisto

Ganymede, one of Jupiter’s moons, has the potential to act as a significant dark matter detector, with upcoming space missions possibly unveiling unique dark matter craters on its ancient terrain.

Researchers typically seek dark matter by looking for lightweight particles that seldom interact with normal matter, employing large, insulated underground detectors. Alternatively, another category of dark matter particles could grow from the size of a basketball to that of an asteroid, but these are infrequent and interact rarely with conventional matter. To detect these hefty dark matter particles, a detector of lunar or planetary scale is necessary to account for their scarcity.

William Derocco from the University of Maryland has proposed that Ganymede, the solar system’s largest moon, may hold clues to these large dark matter particles. His research indicates that they could create a unique crater on the moon’s icy surface, preserved for millions of years due to its stable geology.

Derocco estimates the extent to which these giant dark matter particles penetrate Ganymede’s thick ice layers, finding that they reach the subterranean oceans, fostering unique minerals deeper than a standard asteroid might.

Future missions, such as NASA’s Europa Clipper and ESA’s JUICE, might be able to identify these dark material craters from orbit. Derocco believes these features will be relatively small and distinct, separated from other geological formations. He suggests that “if an underground intrusion radar is used, it may reveal this melted ice column extending down through the ice.”

Utilizing a moon-sized dark matter detector could help identify particles that elude detection on Earth, according to Zachary Picker from UCLA. He states, “Experiments on Earth struggle to find dark matter particles the size of a bowling ball. Particles the size of a refrigerator or car have interactions that are too infrequent.”

The proposal is thorough and well-reasoned, as noted by Bradley Cabana from the University of Cantabria in Spain. “There’s no compelling physical rationale to assume the existence of such massive dark matter particles,” he states. “It’s about exploring all possibilities.” He describes these as extraordinary objects, incredibly dense and held together by formidable forces from obscure sectors.

We Might Have Discovered a Simple Method for Producing Water on the Moon

Researchers have created innovative technologies to extract water from lunar soil, potentially offering vital support for future lunar explorers.

Findings published in the journal Joule highlight how this could significantly lower the astronomical cost of transporting water from Earth, which stands at $22,000 per liter ($83,000 per gallon).

If successfully scaled, this technology may play a crucial role in supporting long-term missions on the moon.

Utilizing samples brought back by China’s Chang’e-5 mission in 2020, scientists showed that water can be extracted from lunar materials and used alongside carbon dioxide to produce essential resources. These resources include oxygen for astronauts to breathe and hydrogen-based chemicals that can be transformed into rocket fuel.

“We never fully imagined the ‘magic’ contained in lunar soil,” said Professor Lou Wang, one of the study’s authors from Shenzhen University and Hong Kong’s China University, in a statement.

“The most surprising aspect of our work was the real success achieved through this integrated approach. One stage of lunar 2O extraction and photothermal CO2 catalysts enhances energy efficiency and simplifies infrastructure development.”

This technique employs a photothermal method (which converts sunlight into heat) to facilitate water extraction and the chemical conversion process.

In laboratory tests, the team employed actual lunar soils from Chang’e-5, along with simulated samples, exposing them to CO2 while concentrating light into a batch reactor. The CO2 used in the conversion process can be easily obtained from astronaut exhalations on the moon.

Previous methods for extracting water from lunar regolith lacked direct links to generating other vital resources. This integrated approach indicates a more efficient advancement; however, researchers recognize that significant challenges persist.

The moon’s extreme temperatures, high radiation levels, and inconsistent soil composition complicate efforts to scale this technology. The amount of CO2 produced by an astronaut’s exhalation may not meet the requirements for complete resource recycling, and the catalytic process still lacks the efficiency needed for sustained life.

Nevertheless, this advancement represents a promising leap towards making life on the moon more viable. There is increasing global interest in establishing a long-term human presence on the moon, and leveraging local water resources could be instrumental for deeper space missions.

Ancient Moon Metstone, 23.5 Billion Years Old, Bridges 100 Million-Year Gap in Lunar History

The examination of North West Africa (NWA) 16286 reveals a lunar metstone with a distinctive chemical profile, offering new perspectives on the evolution of the moon’s interior and emphasizing the enduring nature of its volcanic activity.

Discovered in Africa in 2023, NWA 16286 is one of only 31 moon basalts officially identified on Earth.

The distinct composition of the 311-gram metstone, featuring melted glassy pockets and veins, indicates it was likely impacted by an asteroid or metstone on the lunar surface before being ejected and eventually landing on Earth.

A recent study by researchers at the University of Manchester supports the theory that the moon has maintained internal heat production processes responsible for lunar volcanic activity across various stages.

Lead isotopic analyses suggest that these rock formations are the youngest basalt lunar metstones identified on Earth, dating back approximately 2.35 billion years, a time when lunar samples are scarce.

The sample’s unique geochemical profile distinguishes it from those brought back by previous lunar missions, indicating that its chemical characteristics likely result from lava flows that solidified after ascending from the moon’s depths.

“While the moon rocks returned from sample return missions provide valuable insights, they are limited to the immediate areas around those landing sites,” stated Dr. Joshua Snape from the University of Manchester.

“In contrast, this sample could originate from impact craters located anywhere on the moon’s surface.”

“Thus, there is a unique coincidence with this sample. It fortuitously landed on Earth, unveiling secrets about lunar geology without the need for an extensive space mission.”

The sample contains notably large crystals of olivine and is classified as olivine basalt, characterized by medium titanium levels and high potassium content.

Alongside the atypical age of the samples, researchers found that the lead isotopic composition of the rocks—geochemical signatures preserved when the rocks formed—originates from internal lunar sources with unusually high ratios of uranium and lead.

These chemical markers can assist in identifying the mechanisms behind the moon’s prolonged internal heat production.

“The sample’s age is particularly intriguing as it fills a billion-year gap in the history of lunar volcanism,” Dr. Snape noted.

“It is younger than the basalts collected during the Apollo, Luna, and Chang-E 6 missions, yet significantly older than the more recent rocks retrieved by the Chang-E 5 missions in China.”

“Its age and composition indicate that volcanic activity persisted throughout this entire timeframe, and our analysis suggests a potentially continuous process of heat generation from radioactive elements that generates heat over extended periods.

“Moon rocks are a rarity, making it always exciting to acquire samples that stand out from the norm.”

“This specific rock presents new constraints on the timing and nature of volcanic activity on the moon.”

“We still have much to learn about the lunar geological history. Further analyses to trace surface origins will inform where future sample return missions might be directed.”

The researchers presented their results today at the Goldschmidt Conference 2025 in Prague, Czech Republic.

Asteroid 2024 YR4: On a Collision Course with the Moon, Possible Effects on Earth

Asteroid 2024 YR4 may create the largest lunar impact in the past 5,000 years

Mark Garlic/Science Photo Library/Getty Images

Originally believed to be on a collision path with Earth, asteroid 2024 YR4 still poses some level of threat to our planet. There remains a chance that such celestial bodies could impact the moon, potentially resulting in a catastrophic explosion that could flood Earth with debris capable of damaging satellites.

Astronomers have been monitoring this building-sized asteroid since its detection in December 2024. Initial forecasts heightened the risk of a collision with Earth in 2032, suggesting the impact could unleash enough energy to obliterate a city; fortunately, it now appears 2024 YR4 will likely miss us.

Nonetheless, the likelihood of a lunar impact is gradually increasing, currently estimated at 4.3% based on observations made before the asteroid moved out of our telescopes’ view until 2028. Paul Wiegelt from the University of Western Ontario and his team suggest that such a collision could inflict significant damage on Earth’s satellites.

“We were somewhat taken aback by the amount of debris that could potentially reach Earth,” Wiegert remarked. “In reality, Earth is a surprisingly small target from the moon’s vantage point. Thus, while impacts on Earth are infrequent, gravitational forces can draw in that material under certain conditions.”

Wiegert and his colleagues calculated that 2024 YR4 could create a crater over a kilometer wide on the moon, marking the largest lunar impact in at least the last 5,000 years, albeit still small compared to typical craters. By ejecting debris into space and simulating their trajectories tens of thousands of times, they concluded that this event could lead to collision rates for Earth’s satellites comparable to those observed over years or even days.

While these collisions may not entirely disable a satellite, they could cause significant anomalies due to electrical disruptions. Accurately modeling their potential damage proves challenging, Wiegert noted.

If luck is not on our side, the impact of fragmented materials could be particularly severe, according to Mark Burchell at the University of Kent in the UK. “If they impact a spacecraft’s coolant pipe or an exposed sensor, the loss of critical functions occurs suddenly,” he explained. “Once damaged, satellites cannot be repaired. Even minor issues can lead to serious problems.”

Wiegert emphasized that this scenario should provoke global space agencies to consider deflecting asteroids on a collision course with the moon, similar to efforts aimed at protecting Earth. A NASA Planetary Defense Coordination Agency representative stated that while it is crucial to identify Near-Earth Objects (NEOs) posing potential risks, it is “premature to speculate on possible response options” for a potential 2024 collision.

Depending on how events unfold, swift action could be necessary. When 2024 YR4 reappears in Earth’s telescopic view in 2028, we should be able to refine the precision of its orbital path, Wiegert commented. As chances for a lunar impact rise, it offers a four-year window for decision-making on any necessary actions.

Japan’s Sturdy Lunar Lander Successfully Touches Down on the Moon

The surface of the moon as captured from orbit prior to the crash

ISPACE SMBC X Hakuto-R Venture Moon

On June 5th at 7:13 PM, a Japanese space endeavor aiming to be the third private lunar landing failed as ISPACE’s Resilience lander succumbed on the moon’s surface.

The lander began its descent from around 20 km above the moon, but ISPACE’s mission control quickly lost communication after the probe activated its main engine for final descent, receiving no further signals.

The company announced that the laser tool used to gauge the distance to the surface seemed to malfunction, leading to inadequate slowing of the lander and likely resulting in a collision.

“Given the absence of a successful lunar landing at this time, our top priority is to analyze the telemetry data collected so far and diligently investigate the cause,” stated ISPACE CEO Mr. Takeshi.

Had it succeeded, Resilience would have marked the second private moon landing of the year and the third overall, making it the first non-U.S. company to land on the moon after ISPACE’s prior attempt, the Hakuto-R mission, failed in 2023.

The Resilience Lander embarked on its lunar journey aboard a SpaceX rocket on January 15th, alongside Firefly Aerospace’s Blue Ghost lander. While the Blue Ghost successfully landed on March 2, Resilience took a more circuitous route, moving into deeper space before returning on May 6 to enter lunar orbit. This complex trajectory was essential for targeting the challenging northern plain called Male Frigolis, which had not been surveyed by previous lunar missions.

Equipped with six experiments, the lander included a device for splitting water into hydrogen and oxygen, a module for algae-based food production, and a radiation monitor for deep space. Additionally, it housed a five-kilogram rover named Tenesial, designed to explore and capture images of the moon during the two weeks that Resilience was set to operate.

Private Ispace Resilience Probes Set to Land on the Moon This Week

Artist’s depiction of the Resilience lunar lander

ispace

The private spacecraft is set to attempt a landing this week. Should the Japanese company ISPACE succeed on this attempt, it would mark a historic achievement as the first non-US enterprise to land on the moon, following a failed attempt in 2023.

ISPACE’s Resilience Lander embarked on its journey towards the moon on January 15th. It launched with the assistance of a SpaceX rocket and Firefly Aerospace’s Blue Ghost Lander. While Blue Ghost made a successful landing on March 2nd, Resilience traveled a longer path, traversing deeper into space before entering lunar orbit on May 6th. This intricate route was essential for landing in the hard-to-reach northern plains of Mare Frigoris, which had been uncharted by previous lunar missions.

If the probe executes its landing operations successfully, it will commence its landing sequence on June 5th at approximately 7:20 PM BST, with a landing in Mare Frigoris scheduled an hour later. The landing attempt will be broadcast live on ISPACE’s YouTube channel.

The lander is outfitted with six diverse experiments, including a device capable of splitting moisture into hydrogen and oxygen for usable resources, a module for producing food from algae, and a radiation monitor for deep space studies. Additionally, it will deploy a 5-kilogram rover named Tenalious, tasked with exploring the lunar surface and capturing images during its anticipated two-week mission.

This marks ISPACE’s second attempt at a lunar landing, following the initial Hakuto-R spacecraft, which lost communication and crash-landed on the moon. The company asserts that it has enhanced Resilience with improved sensors leveraging data gathered from the initial mission, yet challenges remain, particularly in slowing the spacecraft from several hundred kilometers per hour to a complete stop in just three minutes. Should ISPACE choose to abort the landing on June 5th, there are three alternate landing sites and dates prepared as contingencies.

Planetary Researchers Discover Wobble-like Atmosphere Similar to Saturn’s Hazy Moon Titan

Titan is the sole moon in our solar system with a significant atmosphere, captivating planetary scientists for years. Recent analysis of archival infrared data from the composite infrared spectrometer (CIRS) onboard the NASA/ESA Cassini-Huygens mission reveals that Titan’s hazy atmosphere does not rotate uniformly with its surface but instead exhibits a wobbly motion akin to that of a seasonally shifting gyroscope.

This view of Titan is among the final images received from NASA’s Cassini spacecraft. Image credit: NASA/JPL-Caltech/Space Science Institute.

“The dynamics of Titan’s atmospheric tilt are quite peculiar,” remarked Dr. Lucy Wright, a postdoctoral researcher at the University of Bristol.

“Titan’s atmosphere acts similarly to a gyroscope and seems to maintain stability in space.”

“We suspect that certain historical events may have displaced the atmosphere from its spin axis, resulting in its wobbling motion.”

“More intriguing is the observation that the degree of this tilt varies with Titan’s seasons.”

Dr. Wright and her team analyzed the symmetry within Titan’s atmospheric temperature field, confirming their hypothesis that it is centrally located at the poles.

However, this symmetry alters over time, corresponding with Titan’s extensive seasonal cycles that span nearly 30 years.

“What complicates matters is that this phenomenon is unaffected by the Sun or Saturn; it remains stationary in space, while the slope direction is fixed,” noted Professor Nick Teenby from the University of Bristol.

“This presents us with a riddle instead of a solution.”

This discovery will impact NASA’s upcoming Dragonfly Mission, a rotorcraft set to reach Titan in the 2030s.

Dragonflies will descend into the atmosphere, subject to the rapid winds of Titan, which are approximately 20 times faster than the surface rotation.

Understanding how the atmosphere wobbles seasonally is crucial for accurately determining the landing trajectory of the Dragonfly.

The tilt influences the payload’s aerial trajectory, making this study vital for engineers in predicting landing sites.

“The Goddard Space Flight Center noted: ‘NASA’s Goddard Space Flight Center plays a significant role globally.”

“This instrument travels across the solar system, continuing to yield valuable scientific insights.”

“The behavior of Titan’s atmosphere as a rotating top detaches from the surface prompts fascinating inquiries that enhance our understanding of atmospheric physics, applicable to both Titan and Earth.”

Survey results were published this week in the Journal of Planetary Science.

Unusual Events on the Moon: Our Team is Left Scratching Their Heads

A recent study by NASA has uncovered an unexpected and curious fact about the moon’s deep interior.

Utilizing data from the Grail Spacecraft, researchers found that the side of the moon facing Earth is “bending” more than the far side, indicating a remarkably unstable internal structure between the two hemispheres.

“We have long believed the moon to be spherically symmetrical deep down, so encountering clear evidence to the contrary was both surprising and challenging,” said Dr. Ryan Park, the study’s lead author and head of the Solar System Dynamics Group at NASA’s Jet Propulsion Laboratory, as reported by BBC Science Focus.

Published in Nature, the study reveals that the moon visible from Earth deforms more significantly under the gravitational influence of Earth than on its far side, measured using ultra-precision gravity techniques.

This finding relies on a metric known as the “Love number,” which quantifies the extent to which a celestial body deforms due to tidal forces. After nearly a decade of intricate calculations involving millions of parameters, the team found that the Love number was approximately 72% greater than what would be expected for a symmetrically spherical moon.

“When we first calculated higher Love numbers than anticipated, our team was genuinely perplexed,” Park noted. However, the calculations confirmed it: the moon exhibits instability both internally and externally.

These views of the near and far side of the moon are compiled from observations by NASA’s Lunar Reconnaissance Orbiter. -NASA/JPL-Caltech

The cause? The mantle on the near side is warmer and less rigid compared to the far side, attributed to radioactive heating early in the moon’s history.

This phenomenon is likely due to ancient geological activities. The near side contains a significantly higher concentration of radioactive materials, including up to 10 times more thorium. These elements emit heat as they decay.

Billion years ago, this heat led to the formation of pockets of partially melted rock, sparking massive volcanic eruptions. These eruptions resurfaced the near side with dark plains known as “Mare,” while the far side remained rugged and cratered.

This study generates the most comprehensive gravity map of the moon to date. Future missions, such as NASA’s Artemis program, aim to enhance navigation on the lunar surface and aid in developing lunar navigation systems.

Looking to other regions of the solar system, Park plans to apply a similar methodology to investigate the metal-rich asteroid Psyche and the icy moons of Jupiter, particularly Europa.

“The most astonishing aspect was how pronounced the asymmetry was,” Park added. “This compelled us to examine the intricacies of the moon’s thermal and structural evolution, ultimately yielding new insights into how the moon—and potentially other celestial bodies—develop internal disparities over billions of years.”

Weather Update from Titan, Saturn’s Moon: Partly Cloudy with Intermittent Methane Rain

With data from the NASA/ESA/CSA James Webb Space Telescope and the Keck II telescope, astronomers have found signs of cloud convection in Titan’s northern hemisphere. The majority of Titan’s lakes and oceans are situated in this region, replenished by sporadic rains of methane and ethane. Webb has also identified essential carbon-containing molecules that offer insight into Titan’s intricate atmospheric chemical processes.



These Titan images taken by Webb on July 11, 2023 show the Keck II telescope on July 14, 2023 (lower row), showing methane clouds (white arrows) appearing at various altitudes in Titan’s northern hemisphere. Image credit: NASA/ESA/CSA/STSCI/KECK Observatory.

Titan is a fascinating world enveloped in a yellowish smog haze. Its atmosphere, primarily composed of nitrogen, experiences weather patterns similar to those on Earth, such as clouds and rain.

In contrast to Earth, where weather is influenced by the evaporation and condensation of water, Titan’s chilly environment features a methane cycle.

Methane evaporates from the surface, rising into the atmosphere to condense into clouds.

Occasionally, icy particles fall to solid surfaces as a form of cold, oily rain.

“The Goddard Space Flight Center involves astronomers,” stated Dr. Connn Nixon, an astronomer at NASA’s Goddard Space Flight Center.

Utilizing both Webb and Keck II telescopes, Dr. Nixon and his team observed Titan in November 2022 and July 2023.

These observations revealed cloud formations in the northern and high northern latitudes of Titan, coinciding with its current summer, and indicated that these clouds were gradually rising to higher altitudes.

Previous research identified cloud convection in southern latitudes, marking the first evidence of similar convection in the northern hemisphere.

This finding is crucial, as most of Titan’s lakes and oceans are located in the northern hemisphere, making evaporation from these bodies of water a primary source for methane.

On Earth, the troposphere, the lowest atmospheric layer, extends to about 12 km in altitude.

However, due to Titan’s low gravity, its troposphere stretches to approximately 45 km.

By utilizing various infrared filters, Webb and Keck explored different atmospheric depths on Titan, enabling astronomers to estimate cloud altitudes.

Researchers noted that clouds seemed to migrate to higher altitudes over a few days, although direct observation of precipitation remains elusive.

“Webb’s observation occurred at the end of Titan’s summer, a season we couldn’t monitor during the NASA/ESA Cassini-Huygens mission,” remarked ESA researcher Dr. Thomas Cornet.

“Combined with ground-based observations, Webb is providing us with valuable new insights into Titan’s atmosphere. This ESA mission could explore the Saturn system in greater detail in the future.”

Titan is of significant astrobiological interest due to its intricate organic (carbon-containing) chemistry, despite its frigid temperatures of minus 180 degrees Celsius.

Organic molecules are the building blocks of life on Earth, and studying them in an environment like Titan may help scientists uncover the processes that contributed to the emergence of life on our planet.

Methane serves as a fundamental component driving much of Titan’s chemistry.

In Titan’s atmosphere, methane is broken down by sunlight or energetic electrons from Saturn’s magnetosphere, leading to the synthesis of ethane-like substances alongside more complex carbon-containing molecules.

The data from Webb provided a crucial missing piece for comprehending these chemical processes: the definitive detection of methyl radicals (CH)3, which form when methane breaks apart.

Identifying this compound signifies that scientists can now observe chemical reactions occurring on Titan for the first time, not just the initial ingredients or the end products.

“We are very enthusiastic about this world,” said Dr. Stephanie Millam, a researcher at NASA’s Goddard Space Flight Center.

This hydrocarbon chemistry will have lasting implications for Titan’s future.

As methane decomposes in the upper atmosphere, some of it recombines to form other molecules, eventually reaching Titan’s surface in one chemical form or another, while some hydrogen escapes into space.

As a result, methane reserves will diminish over time unless there is a source to replenish them.

A similar phenomenon has occurred on Mars, where water molecules were broken down, and the resulting hydrogen was lost to space, culminating in the arid desert planet we observe today.

“In Titan, methane is continuously consumable,” Dr. Nixon explained.

“It could be constantly replenished from the crust and interior for billions of years.”

“If not, eventually it will all disappear, leaving Titan as a desolate landscape of dust and dunes.”

These findings were published in the journal Natural Astronomy.

Chinese Researchers Discover That Moon Rocks Indicate the Possibility of Water on the Moon

The other side of the moon – the part that is always far from the earth – is strangely different from close. It is pockmarked with more craters, with a thicker crust and less Maria, where lava was once formed, or with fewer plains.

Now, scientists say the difference can be more than the depth of the skin.

Using samples from the moon obtained last year, Chinese researchers believe the inside of the moon is potentially drier than its near it. Their discovery, Published Wednesday’s Nature Journal will provide a clearer picture of how pearly orbs we admire in the night sky have formed and evolved over billions of years.

The difference in moisture in the distant side of the moon and its nearby appears to be “accidentally consistent” with variations in the surface features of the two hemispheres of the moon, said Senfu, a researcher at the Chinese Academy of Sciences in Beijing and author of the new results. “It’s very interesting,” he said.

Until the 1990s, when scientists began to discover tips on water on its surface, the moon was believed to be “dry bones.” These tips were confirmed in 2009 when NASA denounced the rocket stage to the moon’s Antarctic.

One of the goals, including this mission, was to estimate the amount of water that lies deep within the moon. The interior of the moon is not changed much by the process of weathering the surface.

Returning to Earth with a Chang’e-6 sample in hand, researchers looked for hardened particles of lava erupted from the female entrance or within the lunar mantle. Some of these basalts were 2.8 billion years old, and contained olivine, a crystal that had ancient magma cooled in the moon and stored information about the composition of the mantle early in the history of the moon.

The amount of hydrogen trapped in olivine allowed scientists to estimate the amount of water present in the mantle at the time. 1-1.5 grams of water for every million grams of the moon rock.

Previous measurements from samples collected near the moon – the US, the Soviet Union, and most recently 200 times wet.

The harsh difference between the range of nearby lunar ranges between nearby and far side samples could suggest that the parts of the moon that we don’t see on Earth are generally much drier, Dr. Hu said.

Shuai Li, a planetary geologist at the University of Hawaii, Manoa, who studies water on the moon, described the results as “very interesting.” However, he pointed out that limited information can be extracted from a single sample.

“It’s hard to say if the far side is definitely dryer than the nearest side,” said Dr. Lee, who was not involved in the job.

One scenario the Chang’e-6 team proposed to explain the internal differences is that the impact of creating the Antarctic-Aitken basin is strong enough to throw water and other elements near the moon, depleting the amount of water beyond.

Another idea is that the basalt in the Chang’e-6 sample comes from a much deeper, dry part of the lunar mantle.

“For me, that’s a little more realistic,” said Mahesh Anand, a planetary scientist at the UK Open University. Estimate the moisture content inside the moon From near-side samples from China collected by the Chang’e-5 mission in 2020.

Dr. Anand also praised the researchers’ careful selection of hundreds of particles from Chang’e-6 samples, less than 16 inches in size, to estimate water abundance.

“The ability to do that is extremely laborious and requires a lot of sophisticated and careful work,” he said.

More samples from various locations collected by future moon missions will help scientists determine whether the inner interior of the width is uniformly dry, and whether it changes throughout the hemisphere.

Melting moon dust to create solar panels on the moon

The base of future moons could be powered by solar cells made on-site from the melted moon dust.

Building items on the moon using materials already there is more practical than shipping them from the Earth. when Felix Lang He heard about this idea at the University of Potsdam in Germany and knew what to do right away. “We have to make solar cells like this, we have to make them right away,” he says.

Two years later, Lang’s team built and tested several solar cells that featured lunar dust as an ingredient. Another important component is a crystal called halide perovskite, which contains elements such as lead, bromine, and iodine, as well as long molecules of carbon, hydrogen and nitrogen.

The team melted a synthetic version of the lunar regolith, a layer of loose rock and dust that covers the moon, into “Moonglass.” Because they did not refine the regolith, the mungrass was less transparent than traditional solar cells. However, Lang says the team’s best prototype still reached around 12% efficiency. More traditional perovskite solar cells typically reach an efficiency close to 26%. Lang said the computer simulation suggests that his team could reach that number in the future.

In general, researchers agree that perovskite solar cells are superior to more traditional silicon-based devices in both space and Earth. From a lunar perspective, the use of perovskite materials is also attractive. This is because it can be kept very thin and reduces the weight of the material transported on the moon. Team estimates that a solar cell with an area of ​​400 square meters requires only about a kilogram of perovskite. This is an impressive claim, I say Ian Crawford at Birkbeck, University of London.

It is equally important that the regolith does not need to be purified. This means that no special reactor is needed. In fact, Lang says that the large curved mirror and sunlight can create a beam of light that is warm enough to make the mungrass. One of his colleagues has already tested the technology on their university roofs and saw signs of legolith melting, he says.

Nicholas Bennett At the University of Technology, Sydney says that while past research has tried to process the lunar regolith into clear glass, this is the first time that solar cells have been shown to work with fine moonglass instead. The challenge now, he says, is to make a lot of mungrass outside the lab. If successful, such melting techniques could help create other items that the moon base needs, such as tiles, Crawford says.

Michael Duke The Lunar and Planetary Institute states that manufacturing moongrass-based solar cells will require many technological advances, from excavating the legend to connecting individual cells. Still, if a solar plant is established on the moon, there could be a positive knock-on effect. In this future, space-based systems like satellites will need less energy to fire payloads from the moon, allowing solar cells covered in the moon rather than what was created on Earth.

Lang and his colleagues are currently working on increasing the efficiency of solar cells. For example, we know whether choosing iron before using magnets to melt Regolith can improve the quality of mungrass.

Ultimately, they want to expand the process to other dusty residents. “We’re already thinking, ‘Can we make this work on Mars Regolith?”,” says Lang.

NASA’s luck turns around with success of Blue Ghost Moon Lander after month of disappointment

NASA took a chance some years back that commercial companies could conduct scientific experiments on the moon at a lower cost than institutions.

Unfortunately, last year, NASA’s initial attempt missed its mark, and the second attempt ended in a crash. However, this month saw success with the robot lander, Blue Ghost, built by Firefly Aerospace in Texas.

On March 16th, as Blue Ghost completed its mission on the moon, the mood at Firefly’s mission operation in Austin was a mix of happiness and bittersweet anticipation for the spacecraft’s demise.

The sun had already set on the lunar surface where Blue Ghost had been working for two weeks, 15 million miles away from Earth.

For solar-powered spacecraft like Blue Ghost, time was running out, and the end was near.

Ray Allensworth, the director of the spaceship program at Firefly, described the atmosphere as light and enthusiastic as they reflected on the successful mission of Blue Ghost.

While other commercial moon missions have faced challenges, Blue Ghost’s success has provided NASA with valuable data for future collaborations.

Scientists like Robert Grimm at the Southwest Institute in Colorado, who led one of the scientific payloads, expressed gratitude for the successful mission, noting that it was better than ending up as a crater.


One of the NASA experiments on Blue Ghost captured images of the lunar surface, providing valuable insights for future missions and research.

The data collected by the cameras will help scientists understand the dynamics of lunar surfaces and potential hazards for future spacecraft landings.

Private Moonlander to go silent two weeks into moon mission

The Light out The first private Lunar Lander A completely successful moon mission.

Firefly Air Space Blue Ghost Lander We were silent over the weekend to close out NASA’s two-week science experiment. The end came when the moon sets, but no longer provides energy Lander’s solar panels.

“The mission is complete,” Firefly CEO Jason Kim said late Sunday night via X. “But the ghosts still live in our hearts and minds.

Lander was open for five hours on a moonlit night, as planned before his death on Sunday evening. Photos of the moon sunset and glow will be released on Tuesday, Kim said.

Blue Ghost was launched by Cape Canaveral in January as part of NASA’s commercial monthly distribution program. It landed on March 2nd at the northeastern edge of the moon. Carrying drills, vacuums and other scientific and technical equipment for NASA. Firefly confirmed on Monday that all 10 experiments worked.

Later last week, Blue Ghost observed a solar eclipse of the total sun from the moon. This is a total lunar eclipse, as seen from the Earth.

Texas-based Firefly has become the first private company to land on the moon without falling or crashing after a series of failed missions by other companies over the past few years. Only five countries in the US, Russia, China, India and Japan have successfully landed.

The lunar lander of the Japanese company shared the SpaceX Rocket Ride, but took an even longer route to reach the moon. That Lander from Ispace is targeting a touchdown in early June.

Another Texas company, an intuitive machine, lay down in a crater near the moon’s Antarctic earlier this month, dooming the mission. This was the second imperfect mission for the intuitive machine. That first Lander brought the US back to the moon for the first time since the Apollo era after a perfect landing that hindered communication last year.

Firefly is already working on the next moon lander, and is striving to land one lunar a year.

Images of Mars and Deimos captured by Hera from a moon

On March 12, 2025, Spatula – ESA’s first space safety mission – reached Deimos, coming within 5,000 km of the surface of Mars and 1,000 km from Deimos. During flybys, the spacecraft deployed scientific payloads for studying Earth and the Moon. Activating the instruments onboard Hera, scientists were able to visualize the surface of Mars and the features of Deimos.

Mars appears bright blue in this near-infrared image of the Hyperscout H Hyperspectral Imager, which was acquired on the Mission’s March 12th Gravity Assisted Flyby. The spacecraft was about 1,000 km from Deimos, 12.4 km in diameter when this image was acquired. In the background, you can observe various Mars features. At the top of the image is the bright Terra Sabaaa area near the equator of Mars, which is outlined in a dark area, with the huygen crater at a distance of 450 km to the left of the Terra Aaa at Sabaaa and the 460 km diameter Shea Parelli Crater. To the bottom right of the Mars disc is one of the largest known impact craters in the solar system, 2,300 km in diameter and over 7 km deep. Image credit: ESA.

Launched on October 7th, 2024, Hera is now en route to visit Dimorphos. Dimorphos was the first asteroid to have its orbit altered by human intervention.

By gathering detailed data on this asteroid, which was affected by NASA’s DART spacecraft in 2022, Hera aims to advance asteroid deflection into a well-understood and potentially replicable technology.

Hera’s Flyby of Mars was a crucial step in the journey through Deep Space, meticulously planned by ESA’s Flight Dynamics team.

Approaching within 5,000 km of Mars, the planet’s gravity assisted in adjusting the spacecraft’s path towards its target.

Traveling at 9 km/s relative to Mars, Hera was able to capture images of Deimos from 1,000 km away, exploring the far side of the tiny moon opposite to the red planet.

“The mission analysis and flight dynamics team at ESOC in Germany did an exceptional job in planning the gravity assist,” said Caglayan Guerbuez, ESA’s Hera Spacecraft Operations Manager.

“In particular, they had to fine-tune the operations to bring Hera closer to Deimos, which added quite a bit of extra work for them!”

Three instruments onboard HERA were utilized during the flyby.

– The asteroid framing camera of the Spara, used for navigation and scientific purposes, captured images in visible light.

– HERA’s Hyperscout H Hyperspectral Imager observed in multiple colors beyond human perception, aiding in characterizing mineral compositions with its 25 visible and near-infrared spectral bands.

– HERA’s thermal infrared imager, provided by the Japan Aerospace Exploration Agency (JAXA), revealed physical properties such as roughness, particle size distribution, and porosity, mapping surface temperatures in mid-red wavelengths.

“These instruments were previously tested before leaving Earth, but this is the first time they were utilized on a distant moon like Deimos where knowledge is limited,” said the Research Director of CNRS, Observatoire de la Côte d’Azur.

“Upon reaching Deimos, one of the HERA instruments remained idle as the others were in use. This is due to the limitation of the Cubesats, which are only activated at slower speeds when at a considerable distance from the target,” added the Research Director.

Hera Asteroid Mission Captures Breathtaking Image of Deimos, Moon of Mars

Mars appears bright blue in this near-infrared image taken by Hera's spacecraft. The month's deimos is a dark mark towards the center of the image

ESA

Space exploration mission to study asteroids that NASA deliberately crashed a spacecraft three years ago takes stunning bonus images of Mars and its moon Deimos is on the way to his final destination.

NASA's 2022 Double Planet Redirect Test (DART) was an attempt to show that bodies on a collision course with the planet could be deliberately redirected to avoid catastrophic effects. Observations from Earth showed that NASA successfully alters the orbit of the asteroid by crushing the 610-kilogram ship into distant asteroid shaped leaves at 6.6 km/sec. Dimorphos did not present any risk to the Earth, and simply acted as a subject.

Hera is a subsequent European Space Agency mission designed to explore the effects of crashes in detail. The craft is the size of a small car weighing 1081 kilograms when fully fueled. It was released on October 7, 2024 from Cape Canaveral, Florida, aboard the SpaceX Falcon 9 Rocket, and on March 12, 2025 I made a flyby to Mars on my way to the asteroid.

Hera came close to 5,000 kilometers to the surface of Mars, received a gravity boost and cast it at Dimorphos. The operation reduced travel time by months and saved fuel.

It was very close to Mars, but I was able to turn on the trio of sensors to take detailed photos of some of the planets. Demos in the same frame. We captured images, infrared cameras and hyperspectral imagers that can sense different colors beyond the limits of the human eye using a 1020 x 1020 pixel resolution.

Hera moved at 9 km/sec compared to Mars, allowing him to image Deimos, a distance of just 1000 kilometers, ranging from 12.4 kilometers long. You can also photograph the side of the moon, which is attractively trapped from Mars, but that's not very common.

Deimos shines much brighter than Mars in this shot taken by Hera's thermal infrared imager

ESA/JAXA

The first concept behind the Hera mission was that it existed when Dart collided with Dimorphos, but delays in funding made it impossible. It will arrive a few years after the impact.

The mission also features two miniature satellites, called Juventus and Milani, or Cubesat. Rather than rotating the traits, these will fly before them and make a drastic pass at smaller, risky distances to collect data. Both are expected to look better if they eventually land on an asteroid and do everything they can in the distance.

Intuitive Machine: Athena Lander Reaches Moon, but Deems to Have Collapsed

IM-2 missions in low lunar orbits

An intuitive machine

The intuitive machine Athena Lander has reached the moon, but appears to have fallen. The Lander is still working, but it is not yet clear which part of the mission will still be able to achieve.

The spacecraft was mounted on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center (KSC) in Cape Canaveral, Florida on February 27th. It landed on March 6th, but the landing was not completely successful, and the exact location or orientation of the lunar surface is still unknown.

“I don’t think we’re in the right attitude on the surface of the moon,” the CEO of the intuitive machine said. Stephen Altmus At a press conference just after landing. This is similar to the company’s last attempt at landing on the moon, the Odysseus spacecraft. It was the first time a private company had landed a spacecraft on the moon, but it turned over to its side and was unable to send much of the data back.

There are a variety of scientific instruments in Athena, but perhaps the most important of these are the regoliths and ice drills to explore new terrain (Trident), a NASA experiment designed to drill up to a maximum metre to a meter through the lunar soil. The purpose is to take samples from underground, analyze their contents, and search for water ice and other compounds.

“This experiment marks an important milestone as it will mark the first robotic drilling activity to be carried out in the Antarctic region of the lunar.” Jacqueline Quinn At KSC at a press conference on February 25th. If Trident is still working, “This is an important step in understanding and leveraging the moon’s resources to support future exploration,” she said.

As part of the IM-2 mission, Athena carried several rovers to the moon. One of them is called Grace after Grace Hopper, a computer scientist and mathematician, and unlike the rover that came before him, he is designed to fly around the surface, firing small boosters to dive into the air up to 100 meters, travelling about 200 meters. Grace aims to explore the strange, permanently shadowed craters of the moon.

Athena operators were able to send craft commands to turn it on and off and downlink some of their data to Earth. The solar panels also function to charge Lander electronics. That seems good news, but the team is still working to figure out which instruments can achieve some of their scientific goals, Altemus said.

This is part of a broader push to increase lunar exploration in preparation for planned human missions over the next decade. The Blue Ghost Lander at Firefly Aerospace arrived in the moon on March 2nd. Resilience Lander, a Japanese company Ispace, is on the way.
