NASA astronauts Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen are set to return to Earth Friday night following a 10-day mission in space.

Their Orion capsule is scheduled to re-enter the atmosphere around 7:53 p.m. ET, embarking on a critical journey expected to take under 15 minutes. If everything goes as planned, the mission will conclude with a splashdown in the Pacific Ocean off San Diego’s coast at 8:07 p.m. ET.

“There’s a 13-minute window where everything must go right,” stated Jeff Radigan, NASA’s Artemis II flight director, at a recent press conference.

Reentry poses significant risks during spaceflight, exposing the craft to temperatures near 5,000 degrees Fahrenheit as it plunges through the atmosphere. This risk is heightened for Artemis II due to a known design flaw in the Orion spacecraft’s heat shield, crucial for shielding astronauts from extreme heat.

This marks the first crewed mission for the Orion capsule.

After the uncrewed Artemis I mission in 2022, NASA detected unexpected damage to the spacecraft’s heat shield.

NASA’s Orion spacecraft was recovered post-Artemis I test flight and transported to Kennedy Space Center in Florida, where its heat shield underwent inspection.

NASA’s research revealed that certain materials in the heat shield cracked upon atmospheric reentry, leading to “charred material flaking off” in various areas. An investigation found that improper gas venting within the heat shield’s outer layers created pressure buildup, resulting in the damage.

As a result of these findings, NASA intends to revise the heat shield design for subsequent Artemis missions. The Orion spacecraft for future flights will feature a more permeable outer material layer. Unfortunately, by the time NASA identified the damage from Artemis I, the Artemis II capsule was already built and assembled.

Rather than redesign the heat shield, NASA adjusted the capsule’s reentry trajectory to mitigate risks for the astronauts. The Orion spacecraft typically descends into the atmosphere, “skipping” like a stone on water to lessen thermal stress and gravitational forces before its final descent. NASA Deputy Administrator Amit Kshatriya explained that this “skip” will be brief, allowing the capsule to descend more rapidly and at a steeper angle, thereby reducing exposure to extreme temperatures.

“All systems demonstrated over the past nine days, including life support, navigation, propulsion, and communications, hinge on the flight’s final moments,” stated Kshatriya during a Thursday media briefing.

He further expressed “high confidence” in the spacecraft’s heat shield with the optimized flight path.

Nonetheless, substantial risks remain, with the lives of four astronauts at stake.

Former NASA astronaut Charlie Camarda voiced concerns regarding the heat shield, suggesting NASA should have delayed the Artemis II launch pending further assessment of the existing design.

“History shows that incidents occur when organizations misjudge the complexities of problems. This issue mirrors patterns seen prior to previous tragedies,” he articulated in an open letter to NASA Administrator Jared Isaacman in January.

Conversely, Isaacman declared earlier this month that he holds “full confidence” in the performance of Orion’s heat shield.

Wiseman conveyed satisfaction with the current plan.

“If we adhere to the newly-established atmospheric entry path, this heat shield is safe for flight,” he affirmed during a pre-flight media event in July.

Radigan noted that precise orbital positioning is essential for the atmospheric reentry protocol. Mission control has dedicated significant effort over the past day and a half to maintain the Orion spacecraft’s orbital path, executing necessary engine burns.

“Avoid actions that are impossible,” Radigan emphasized. “Hitting the required angle is crucial for successful atmospheric reentry.”

During reentry, the Orion capsule is projected to achieve speeds nearing 24,000 miles per hour, with astronauts experiencing gravitational forces approximately 3.9 times that of Earth.

As the capsule penetrates the atmosphere, communication blackouts are anticipated due to plasma buildup surrounding the craft. Flight director Rick Henfling announced that this disruption is expected to last around six minutes.

“Post-blackout, Orion will be at approximately 150,000 feet, still descending rapidly,” he noted.

On Saturday, Artemis II commander Reed Wiseman gazed back at Earth from the Orion spacecraft’s main cabin.

At approximately 6,000 feet altitude, the capsule will deploy three main parachutes to decelerate to about 20 miles per hour before making contact with the ocean.

The U.S. Navy is set to assist with recovery operations in the Pacific. Following confirmation of a safe landing area, NASA plans to extract Koch from the capsule first, followed in order by Glover, Hansen, and Wiseman.

At a press conference on Thursday, Kshatriya commended the crew, emphasizing it was time for flight officials, engineers, and recovery teams to bring them home.

“The crew has performed their duties,” he stated. “Now it’s our turn to execute our part.”

Artemis II Astronauts Gear Up for Moon Mission After Overcoming Toilet and Email Challenges

“The aircraft itself had no issues,” stated NASA Administrator Jared Isaacman during a post-launch press conference on Wednesday. “We have re-established communications with the crew and are actively addressing this challenge.”

Crew members noted that a fault light was triggered while testing the ship’s toilets on Wednesday.

The Orion capsule features the Universal Waste Management System for its toilets, designed to drain urine into space while storing feces for crew return. A privacy door enhances comfort during use. A similar system has been tested aboard the International Space Station.

Mission managers collaborated with the astronauts overnight to troubleshoot this problem, and early Thursday, NASA confirmed that the crew successfully resolved the issue. You can read more about the toilet’s restoration.

If the issue hadn’t been resolved, the backup plan involved the use of a “collapsible emergency urinal” for urine collection in bags, while toilets would still be operational for fecal storage.

Another relatable issue for many on Earth arose when the astronauts asked for technical assistance with their computers. The culprit? Microsoft Outlook.

“I also have two versions of Microsoft Outlook, and neither one was functioning,” remarked mission commander Wiseman, who transmitted this discovery via radio to ground control.

Ultimately, mission controllers managed to access the computers remotely, successfully restoring Outlook functionality for the astronauts.

These initial glitches were swiftly adjusted, leading to an important milestone for the Artemis II astronauts on the mission’s second day.

After replenishing their energy, the astronauts received a wake-up call on Thursday at 2:35 p.m. ET. They were greeted by John Legend’s “Green Light” and encouraging messages from NASA team members who supported their journey. Glover expressed gratitude for their uplifting words.

Less than two hours post-wakeup, mission managers in Houston convened to discuss the feasibility of executing a critical engine burn to position the Orion capsule into lunar orbit.

The decision was a resounding “go.”

This pivotal maneuver, known as the “lunar insertion burn,” is scheduled for 7:49 p.m. ET and will last just under six minutes. The main engine of Orion will ignite, propelling the capsule out of Earth’s orbit.

The Artemis II mission’s spaceflight heavily depends on gravitational forces from both the Earth and the Moon, making this upcoming engine burn crucial. This will be the last major maneuver of this nature during the mission; once executed, the astronauts will embark on a one-way journey around the Moon.

“Flight controllers will monitor engine performance, guidance, and navigation data closely throughout this maneuver to ensure Orion is precisely targeted for its outbound journey,” NASA officials mentioned in a blog update.

If all goes smoothly, the Artemis II astronauts will make history as the first crew to journey to the Moon since Apollo 17 in 1972.

The highly anticipated Artemis II mission is set to launch as early as April 1, 2024. This groundbreaking NASA mission will mark the first crewed journey to orbit the Moon since 1972, allowing astronauts to capture stunning images of the Moon’s far side, a region yet to be seen by human eyes.

Originally scheduled for 2019, Artemis II faced numerous delays stemming from the earlier uncrewed Artemis I mission, launched successfully in 2022. Artemis I tested the capabilities of the Space Launch System (SLS) rocket and Orion crew capsule.

This time, Artemis II will carry a crew of four astronauts: NASA’s Reed Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency’s Jeremy Hansen.

After a “wet dress rehearsal” in February revealed a minor fuel leak, NASA successfully resolved the issue, returning the vehicle to the launch pad for final preparations. The astronauts are now in quarantine, eagerly awaiting their mission.

At a press conference held on March 29, Commander Wiseman stressed the significance of this mission as a crucial test for both the SLS rocket and Orion capsule. “This is the first time we’re trying this. We’re ready to go, but we won’t launch until we’re absolutely certain the vehicle is ready,” he stated.

If the launch does not take place by April 6, the next available opportunity will be April 30, with subsequent windows opening in May.

Once launched, the SLS rocket will spend two days orbiting Earth, during which the crew will test life support systems and maneuver the Orion capsule for docking with older spacecraft. Following this preparatory phase, the crew will embark on an eight-day journey around the Moon.

This journey will provide the first views of regions on the Moon’s far side, including the Mare Orientale crater, which has only been previously photographed by satellites. “We all think we’ve been to the moon, but approximately 60 percent of the far side is still unexplored,” Wiseman noted during the conference.

Artemis II represents a significant milestone in NASA’s long-term Artemis program. While initial plans included lunar landings by Artemis III, this has now been postponed to Artemis IV, focusing instead on preparing for future lunar operations. Artemis III is slated for 2027, followed by Artemis IV and potentially V in 2028.

These missions aim to establish a permanent human presence on the Moon, paving the way for future explorations. “We’re excited to play our part in this monumental journey, and upon our return, we hope to inspire the next generation,” Hansen said at the conference.

How NASA’s Artemis II Achieved a Successful Moon Mission

NASA officials have announced that future heat shields will be optimized with a more transparent outer material to enhance performance. However, for the Artemis II mission, the heat shield design will remain unchanged.

To mitigate risks to astronauts, mission managers are altering the Orion spacecraft’s reentry trajectory. Instead of the usual atmospheric reentry that simulates a “bouncing stone” effect to reduce thermal stress, this mission will feature a faster, steeper descent to minimize exposure to extreme temperatures.

NASA has confirmed that this revised plan is the result of extensive testing. Isaacman expressed his “complete confidence” in the heat shield during a January update.

During a media event in July, Wiseman echoed this sentiment, stating: “If we adhere to NASA’s new atmospheric entry path, this heat shield will be safe for flight.”

Countdown to the Moon Landing: Two Years Remaining

A significant critique of the Artemis program focuses on its timeline. Nearly four years have passed since Artemis I took flight, and until recently, the next launch, Artemis II, was slated for another two-year wait.

Critics argue that compared to agile private companies like SpaceX, NASA’s slower improvement cycles lead to longer wait times, jeopardizing program security.

Dryer emphasized that “the infrequent launches of space systems pose major structural and safety risks that have been acknowledged for years,” asserting, “We have a limited window to identify potential failure modes.”

To address these challenges, Isaacman has initiated vital improvements to the Artemis program, including the addition of more missions and an accelerated launch schedule.

The Artemis III mission, which was originally set to land astronauts on the moon in 2028, is now scheduled to launch into low Earth orbit in mid-2027 for essential technology tests and demonstrations. NASA’s detailed strategy for landing on the lunar surface also includes a second spacecraft—a lander developed by SpaceX or Blue Origin. This lander will rendezvous with Orion in lunar orbit to transport astronauts to the moon. Artemis III is positioned to conduct these critical maneuvers. However, challenges persist in the commercial sector, as reported in a recent report, revealing that SpaceX’s Starship lander is “at least two years behind schedule, with expectations for additional delays.”

Under the revamped strategy, NASA aims to achieve a lunar landing by the Artemis IV mission in 2028.

Key changes include the target of launching Space Launch System rockets approximately every 10 months, compared to the previous three-year intervals, according to Isaacman.

The overall progress hinges on the success of the Artemis II mission, which could provide a much-needed boost for NASA and the American public.

“Whenever the White House seeks positive news, they turn to NASA,” Melroy remarked.

NASA Moves Artemis II Moon Rocket Back to Launch Pad for Upcoming Mission

NASA is set to return its colossal moon rocket to the launch pad at Kennedy Space Center in Florida on Thursday night, gearing up for the much-anticipated lunar journey with four astronauts aboard.

The impressive 322-foot-tall Space Launch System (SLS) rocket, carrying the Orion capsule, is on track for a launch that could initiate a 10-day mission as early as April 1. Before this, the rocket and spacecraft must conduct a meticulous four-mile trek from the hangar to the launch pad.

This journey is expected to commence at 8:00 PM ET and wrap up approximately 12 hours later.

This marks the second rollout for the 11-million-pound rocket. Initially rolled out to the launch pad in mid-January, it returned to the vehicle assembly building for necessary repairs after engineers identified a helium flow blockage a few weeks ago.

Utilizing a mobile platform known as a crawler transporter, the rocket will be moved back to its launch pad, progressing at a steady pace of about 1 mile per hour.

The upcoming mission, titled Artemis II, will mark the first time humans are launched aboard NASA’s Space Launch System and Orion spacecraft. This mission follows the 2022 unmanned Artemis I mission, which orbited the moon. The crew, including NASA astronauts Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen, could achieve unprecedented distances from Earth as they navigate around the moon.

NASA successfully resolved the helium flow issue while the rocket was in the hangar by replacing a crucial seal in the helium supply line. Engineers also changed batteries on both the rocket and Orion spacecraft, conducting rigorous tests to ensure readiness.

The helium issue came to light during extensive refueling tests and a launch-day rehearsal known as a wet dress rehearsal. This was the second rehearsal for the SLS, as the first had to be halted due to a hydrogen leak detected at the rocket’s rear end.

Last week, NASA officials conducted a comprehensive two-day Flight Readiness Review, bringing together mission managers, four astronauts, and key representatives to evaluate the upcoming flight, assess risks, and outline the necessary steps ahead. The agency confirmed its decision in April to proceed with launch preparations, officially certifying the rocket and spacecraft for their historic mission.

NASA Plans Astronaut Moon Mission Launch for April 1st

NASA has exciting news! On Thursday, the space agency announced its plans to launch four astronauts on a long-anticipated mission around the moon, aiming for a launch date as early as April 1.

Lori Glaze, the acting deputy administrator for NASA’s Exploration Systems Development Mission Directorate, stated that the team is on schedule to return the Space Launch System (SLS) rocket and Orion spacecraft to the launch pad at Kennedy Space Center in Florida on March 19.

“Everything is progressing well,” Glaze declared during a news conference.

The mission, named Artemis II, marks a significant milestone, as it will be the first time NASA’s SLS rocket and Orion capsule will carry astronauts. It’s the first crewed lunar journey in over 50 years.

This 10-day mission will have a crew of NASA astronauts Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen, who will orbit the moon farther from Earth than any humans have ever ventured.

The launch is targeted for April 1 at 6:24 p.m. ET; however, this date hinges on the completion of the rocket’s checkout in its hangar and further work on the launch pad.

NASA made the decision to proceed with the launch attempt shortly after mission managers and top officials gathered for a two-day flight readiness review, where they formally certify rockets and spacecraft for flight.

Glaze noted that Wiseman, Koch, Glover, and Hansen took part in the flight readiness review virtually, sharing their vital insights.

“Their participation reaffirmed the importance of having transparent discussions about our future steps and the risks involved,” she explained.

The astronauts are currently training at NASA’s Johnson Space Center in Houston and will enter quarantine on-site starting Wednesday to minimize germ exposure before launch. If everything goes smoothly, they will travel to Kennedy Space Center on March 27, as noted by Sean Quinn, NASA’s Exploration Ground Systems Program Manager.

The impressive 322-foot-tall Space Launch System rocket has been undergoing repairs since its relocation from the launch pad on February 25.

This action followed a crucial refueling test on February 19, known as a “wet dress rehearsal,” where NASA simulated nearly every step of a launch countdown. Despite a successful rehearsal, engineers later identified a blockage in the helium flow to a section of the rocket’s upper stage, prompting the cancellation of the launch to make necessary repairs and missing out on a March launch window.

Quinn mentioned that engineers have recently replaced a faulty seal that was obstructing the helium flow. The team is also adding new batteries and conducting tests on the systems of the rocket and Orion spacecraft.

The February 19 wet dress rehearsal was NASA’s second attempt to fill a Space Launch System rocket with over 700,000 gallons of cryogenic propellant. The earlier attempt that month was cut short due to a hydrogen fuel leak discovered at the rear of the rocket, eliminating the opportunity for a February launch.

NASA is exploring a launch opportunity that includes April 2, which wasn’t initially considered, but was added after further analysis. If needed, there is also an opportunity on April 30.

The agency has opted not to speculate on any potential launch dates beyond April due to possible delays.

Thus far, the SLS rocket and Orion capsule’s only spaceflight was the unmanned lunar orbit during the 2022 Artemis I mission, which faced a six-month delay due to a hydrogen leak.

Recently, NASA announced significant revisions to its Artemis moon program. Following Artemis II, the agency has rescheduled the Artemis III mission to land astronauts on the moon to mid-2027 and will instead operate in low-Earth orbit to test technologies. These tests will involve rendezvous and docking with SpaceX’s and Blue Origin’s commercially developed lunar landers.

After that, Artemis IV is slated for a 2028 launch to safely land astronauts on the moon.

NASA Administrator Jared Isaacman stated these changes aim to enhance safety and minimize delays in fulfilling President Donald Trump’s objective of returning astronauts to the lunar surface and establishing a sustainable human presence there.

Juice Spy: Exploring the 3I/ATLAS Interstellar Comet Mission

ESA’s Jupiter Icy Satellite Explorer (JUICE) has unveiled new images of the interstellar object 3I/ATLAS captured by the JANUS scientific camera.



This striking image of interstellar comet 3I/ATLAS was taken by the JANUS camera aboard ESA’s JUICE spacecraft on November 6, 2025, just seven days post the comet’s closest approach to the Sun. At this juncture, JUICE was approximately 66 million kilometers (41 million miles) from the comet. The inset image enhances the coma structure, with the arrow indicating the comet’s movement direction (blue) and its trajectory relative to the Sun (yellow). Image credit: ESA / Juice / JANUS.

The interstellar comet 3I/ATLAS was first identified on July 1, 2025, by the NASA-funded ATLAS survey telescope located in Rio Hurtado, Chile.

This remarkable comet, also known as C/2025 N1 (ATLAS) and A11pl3Z, appears to have entered our solar system from the constellation Sagittarius.

3I/ATLAS boasts the most dynamically extreme orbit ever recorded in the solar system, underscoring its interstellar origin and exceptional speed.

On October 30, 2025, the comet achieved its closest perihelion to the Sun, reaching within 1.4 astronomical units (210 million kilometers, or 130.5 million miles)—just inside Mars’ orbital path.

Throughout November 2025, the JUICE spacecraft meticulously observed 3I/ATLAS utilizing five scientific instruments: JANUS, MAJIS, SWI, PEP, and UVS.

These instruments collectively gathered crucial information on the comet’s behavior and composition.

“For several months post observation, JUICE was positioned on the opposite side of the Sun from Earth,” noted members of the JUICE team.

“We utilized the main high-gain antenna as a heat shield, while the smaller medium-gain antenna transmitted data back to Earth at a reduced rate.”

“Consequently, we had to wait until last week to receive the data,” they elaborated.

“Currently, we are diligently analyzing these findings.”

The JANUS camera successfully captured over 120 images of 3I/ATLAS across a broad range of wavelengths.

Researchers are actively studying these images to enhance their understanding of the comet.

Additionally, they are examining spectroscopic data as well as information regarding the comet’s composition and particle characteristics.

“[The latest JANUS image] reveals a jet emerging from the core of 3I/ATLAS, directed away from the Sun,” stated Professor Avi Loeb of Harvard University in his analysis.

“This observation is intriguing because jets are typically formed from pockets of ice on the surface that get heated by sunlight on the day side, creating jets that originally travel toward the Sun.”

“It’s comparable to images captured by amateur astronomers globally during the same period.”

NASA Plans Lunar Orbit Mission to Launch Astronauts by March 6th

NASA is set to launch four astronauts on the highly anticipated Artemis II mission, scheduled for March 6. This groundbreaking flight will take astronauts around the moon, marking a historic return to lunar exploration.

The launch date was confirmed after NASA successfully filled the Space Launch System (SLS) rocket with over 700,000 gallons of cryogenic propellant and completed a comprehensive refueling test. This test simulated nearly every countdown step and launch-day procedures.

A successful wet dress rehearsal indicates that astronauts could be just two weeks away from visiting the moon for the first time in over half a century.

The Artemis II mission will be historic, as it will be the first time NASA’s Space Launch System rocket and Orion capsule carry humans. The mission is set to last 10 days, during which astronauts will journey farther from Earth than any humans have ever traveled.

Thursday’s extensive refueling test signaled significant progress for NASA. This was the second attempt at a wet dress rehearsal; the first was halted on February 2 due to a hydrogen fuel leak detected in the rocket’s rear. This issue led mission managers to abandon all launch windows for February.

Lori Glaze, acting deputy administrator for NASA’s Exploration Systems Development Mission Directorate, emphasized that the March 6 launch depends on completing necessary work on the launch pad and the thorough evaluation of the wet dress rehearsal results.

The mission team plans to hold a flight readiness review next week, where NASA managers and executives will officially certify the rocket and spacecraft for flight.

“Everything is set in front of us,” Glaze stated at a press conference on Friday. “If we can get through these final preparations, we are in a strong position to target March 6.”

In the interim between the first and second wet dress rehearsals, engineers addressed earlier leaks by replacing two seals in the fuel supply line and conducting repairs and tests on the launch pad. Artemis launch director Charlie Blackwell-Thompson reported that the seals are now “rock solid” after the recent repairs.

“Overcoming this wet dress rehearsal milestone was crucial for our progress,” she noted.

The Artemis II crew consists of NASA astronauts Reed Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen. While they did not participate in the wet dress rehearsal, several crew members were present at Kennedy Space Center, Florida, during the test.

“I had the opportunity to speak with Reid Wiseman, Christina Koch, and Jeremy Hansen,” Glaze shared. “They are extremely enthusiastic about the possibility of a March launch.”

To ensure their health ahead of the mission, the astronauts will undergo quarantine in Houston starting Friday afternoon. They will arrive in Florida about five days before the launch and continue their pre-flight quarantine at Kennedy Space Center.

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.

Koch expressed her contentment about not participating in another significant milestone, stating her excitement for her colleagues who are set to leave footprints on the lunar surface.

“I’m genuinely thrilled to see familiar faces taking steps toward walking on the moon. However, if that is not my destiny, I am completely at peace with it,” Koch mentioned, noting NASA has yet to assign a crew for the Artemis III mission.

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.”

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.

BepiColombo Mission Launches in 2026: Unveiling the Secrets of Mercury

Artist’s Impression of BepiColombo Spacecraft Near Mercury

In 2026, the highly anticipated BepiColombo spacecraft is set to orbit Mercury, promising to unlock the planet’s long-standing mysteries.

BepiColombo is a collaborative mission involving the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA). This intricate mission includes the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (Mio), tethered to the Mercury Transport Module (MTM).

Since its launch in 2018, the MTM has made six flybys of Mercury, skillfully utilizing the planet’s gravity to facilitate its descent into orbit, a method pioneered by Giuseppe “Bepi” Colombo.

This mission has already gathered crucial scientific insights, including data about the solar wind and high-resolution imagery of Mercury’s surface. However, the MPO’s advanced instruments, including X-ray spectrometers, remain inactive due to obstructions by the MTM.

In September 2026, the MPO and Mio will detach from the MTM, embarking on their final descent into orbit, completing this phase by November when their focus will shift to detailed studies of Mercury.

According to Charlie Feldman, a researcher at the University of Leicester who contributed to the MPO’s instruments, “We’re hopeful that our equipment will function as intended. With the extensive time invested in building it, the excitement comes with a degree of anxiety.”

Alongside capturing intricate details of Mercury’s magnetosphere, the MPO will extensively map and analyze the planet’s surface using its spectrometer and other tools. “This represents the first X-ray imagery of an extraterrestrial surface,” Feldman noted.

Such observations may unravel enigmas surrounding the significant X-ray emissions detected from Mercury’s night side in prior missions. Additionally, the spacecraft will assess X-rays emitted from the sun-facing side, unearthing new insights into Mercury’s geological composition and evolution. “Deciphering how planets formed gives us a broader understanding of solar system dynamics,” Feldman stated.

MMX spacecraft visiting Mars moon

MMX Spacecraft to Explore Mars Moons

The mystery surrounding the origins of Mars’s moons, Phobos and Deimos, may soon be unraveled with the launch of the MMX spacecraft, set to return samples from Phobos to Earth in 2026.

“While we understand the origin of Earth’s moon, the origins of Phobos and Deimos remain unclear,” says Emelia Brannagan-Harris from the Natural History Museum in London. “By exploring the origins of these moons, we aim to gain insights into Mars’s evolutionary history.”

There are two leading theories regarding how these moons came to orbit Mars. The first theory suggests that they are remnants of asteroids that either merged and then separated or closely orbit each other. The second theory posits that they may have formed from an asteroid impact on Mars, similar to the formation of Earth’s moon.

Currently, evidence supports neither scenario definitively. However, the Japan Aerospace Exploration Agency’s Mars Moon Explorer (MMX), scheduled for launch in 2026, is equipped to clarify which theory holds true. This spacecraft will observe both moons and send a rover to gather samples from Phobos’s surface and subsurface.

If the observations reveal a prevalence of carbon-rich materials and water, it could support the theory of asteroid capture. Conversely, if such materials are absent, we may need to await the analysis of the collected samples, expected to return to Earth by 2031.

The Phobos samples will include both surface material and samples from beneath the surface. Testing this material will allow scientists to investigate signs of past dissolution, potentially indicating interactions with Mars’s atmosphere or surface.

Regardless of the origins of Phobos, its close orbit around Mars suggests it may hold well-preserved samples from early Mars. “Phobos might also contain ancient debris from Mars’s period of liquid water, offering significant insights into the planet’s history,” Brannagan-Harris emphasizes.

What Does Russia’s Failure to Launch a Crewed Mission Mean for the ISS?

Soyuz spacecraft launched on November 27th

Roscosmos Space Agency, via AP/Alamy

The International Space Station (ISS) might be facing a significant shift towards reduced international collaboration. A critical launch site in Russia, the only one capable of sending humans into orbit, has been heavily damaged and could remain non-operational for up to two years. This situation presents a challenging dilemma for NASA: either shoulder increased expenses and duties or consider decommissioning the ISS.

The Soyuz spacecraft took off from the Baikonur Cosmodrome in Kazakhstan on November 27, transporting two cosmonauts alongside an American astronaut. While all three arrived at the ISS safely, subsequent evaluations of the launch pads revealed that a crucial multi-layered support structure, which is typically retracted during the initial launch phases, had collapsed into the flame trench, sustaining significant damage.

According to reports, repairs might take as long as two years. The Russian space agency, Roscosmos, stated that damage repairs will begin “soon.” The actual extent of the issues remains uncertain.

While the Baikonur Cosmodrome has several launch pads, the damaged one, Site 31, Launch Pad 6, has been operational since 1958 and is the only pad configured for manned missions. David Amato from Imperial College London notes that alternative Russian launch facilities face similar complications that eliminate their viability. The Plesetsk Cosmodrome, located 650 kilometers northeast of St. Petersburg, is positioned too far north for efficient ISS launches, while Vostochny Cosmodrome, near the Chinese border, lacks sufficient infrastructure.

“Many space missions hinge on critical vulnerabilities like this, particularly those that are winding down, such as the ISS,” Amato indicated.

Certainly, the ISS’s operational lifespan has exceeded expectations, having initially been planned for decommissioning in 2020, with several delays thereafter. Current intentions forecast a gradual descent to lower orbits beginning next year, potentially lasting until 2030, after which the crew will dismantle its functional and historic equipment before its final descent toward Earth, expected to fully disintegrate by 2031. Details regarding this process can be found here: “A 400-ton mass of flame is hurtling through the upper atmosphere at orbital velocity.”

Should Russia withdraw, NASA would likely need to further invest in resources and funds to maintain ISS operations—a daunting prospect, especially since the program is nearing its conclusion.

However, Amato casts doubt on whether the U.S. aims to fully terminate the ISS. Without it, both the U.S. and Europe would lack a venue for astronauts, leading to minimal incentives to launch personnel into orbit until longer-term projects like a commercial space station or lunar habitats are established. In contrast, China, America’s principal economic competitor, operates a flourishing space station.

“The optics are not favorable,” Amato noted, “and losing the ISS would be substantial since invaluable research facilitated by this platform would cease to exist.”

The ISS’s inception in the 1990s emerged from a different geopolitical context. Following the Soviet Union’s collapse, there was a mutual interest in launching a collaborative initiative between the former superpowers. The ISS was meticulously crafted to foster not only cooperation but to necessitate it. The Russian orbital segment (ROS), managed by Roscosmos, plays a critical role in trajectory control, while the US orbital segment (USOS), overseen by NASA and collaborated on with European, Japanese, and Canadian space agencies, is solar-powered. Cooperation is essential for both components to function effectively.

However, relationships have soured, and current tensions between the United States and Russia parallel geopolitical strains on Earth, a reality worsened by Russia’s annexation of Crimea in 2014 and the full-scale invasion of Ukraine in 2022.

Should Russia entirely pull out from the ISS partnership, NASA and its counterparts would face the daunting task of transporting not only astronauts but also crucial supplies like fuel and food—a responsibility previously managed by Russia. NASA would have to address these adjustments. There are more complex inquiries to address, notably regarding the formal management and operation of the Russian section of the ISS. Given recent budget reductions, NASA must scrutinize the feasibility of such an undertaking.

As of this writing, many of Roscosmos’ websites are down, and inquiries regarding the condition of Site 31 have gone unanswered. The European and Canadian space agencies have also not replied to media requests for commentary on the situation with Roscosmos. New Scientist reports.

Nadie Russell, a NASA Public Relations Officer, told New Scientist that the agency would “collaborate closely with our international partners, including Roscosmos, to ensure the safe operation of the ISS and its crew.” Nonetheless, Russell refrained from addressing specific queries about Russia’s ongoing involvement or whether contingency measures are in place should Russia choose to disengage.

Russia has time to evaluate these matters before its next crewed flight to the ISS, slated for July, although it must quickly formulate a strategy to rectify the issues at Baikonur.

Lia Nani Alconcel, a professor at the University of Birmingham in the UK, points out that there are alternatives for crewed travel to the ISS, such as SpaceX’s Dragon capsule, which has successfully transported American astronauts to orbit. Should U.S.-based SpaceX become the sole option for reaching the ISS, it would represent a stark reversal from the early 2000s, when the U.S. was dependent on Russia for crew transport after the retirement of the Space Shuttle.

“Contractual issues may arise regarding launch agreements, but those are legal matters, not engineering challenges,” Alconcel remarked.

This alternative approach could ease some burdens on NASA and alleviate the pressure of urgently needing to establish a new program to compensate for the loss of Russian expertise and capabilities.

“Roscosmos specifically trains astronauts for essential tasks related to the Russian orbital segment, making it a formidable challenge for NASA to independently operate the ISS,” Alconcel explained, highlighting that NASA is pursuing a similar approach on the American segment.

Planetary Scientists Suggest Mission to Investigate Upcoming Interstellar Comet

Researchers at the Southwest Research Institute have completed a study outlining how the proposed spacecraft could fly by interstellar comets, offering valuable insights into properties of these bodies throughout the solar system. Leveraging recent findings from interstellar comet 3i/Atlas, they explored mission concepts and concluded that the proposed spacecraft could potentially intercept and observe 3i/Atlas.



Hubble captured this image of 3i/Atlas when it was 446 million km (277 million miles) from Earth on July 21, 2025. Image credits: NASA/ESA/David Jewitt, UCLA/Joseph Depasquale, Stsci.

In 2017, interstellar object 1i/’oumuamua became the first interstellar comet identified within the solar system.

Following that, the second interstellar comet, 2i/Borisov, was discovered in 2019, and recently, 3i/Atlas was identified this year.

“These novel types of objects present the first true opportunity for humanity to closely examine bodies formed in other star systems,” said Dr. Alan Stern, a planetary scientist at the Southwest Research Institute.

“Flybys of interstellar comets could yield unparalleled insight into their composition, structure, and characteristics, significantly enhancing our understanding of the solid body formation process in diverse star systems.”

Scientists estimate that numerous interstellar objects from distant origins cross Earth’s orbit each year, with up to 10,000 potentially entering Neptune’s orbit in certain seasons.

Dr. Stern and colleagues tackled unique design challenges while defining the costs and payload requirements for interstellar comet missions.

The hyperbolic trajectories and high velocities of these bodies present challenges for current avoidance methods, but this study indicated that Flybee reconnaissance is both feasible and cost-effective.

“The trajectory of 3i/Atlas falls within the intermittent range of missions we designed, and the scientific observations taken during such flybys would be groundbreaking,” stated Dr. Matthew Freeman from the Southwest Institute.

“The proposed mission would involve a rapid, frontal flyby, allowing us to gather substantial valuable data while also serving as a blueprint for future missions to other interstellar comets.”

The research establishes a significant scientific objective for its mission targeting interstellar comets.

Understanding the physical characteristics of a body sheds light on its formation and evolution.

Investigating the composition of interstellar comets may aid in explaining their origins and how evolutionary forces have shaped them since their inception.

Another objective is to thoroughly examine the coma of an object, the escaping atmosphere emanating from its center.

To devise mission orbital options, researchers created software to generate representative synthetic populations of interstellar comets, calculating the minimum energy trajectories from Earth to each comet’s pathway.

Software analyses have indicated that low-energy rendezvous trajectories are achievable, often requiring fewer resources during launch and flight compared to other solar system missions.

Scientists utilized the software to determine the trajectory the proposed spacecraft may have taken from Earth to intercept 3i/Atlas.

They found that the mission could potentially have reached 3i/Atlas.

“It’s incredibly promising regarding the emergence of 3i/Atlas,” noted Dr. Mark Tapley, an orbital mechanics expert at the Southwest Research Institute.

“We have demonstrated that there’s no need to launch any existing technology or mission frameworks that NASA has already employed to engage these interstellar comets.”

Women’s Mission to Mars: An Opera on Acquiring the Red Planet’s Toxic Technical Resources

Writing an opera centered around Mars? Mars represents more than just a celestial body; it embodies philosophy and ideology. Humanity’s perception of it evolves over time, mirroring the complex blend of beliefs, aspirations, dreams, and fears that characterize each era.

In 1965, NASA’s Mariner 4 flew by Mars, delivering the first detailed images of the red planet back to Earth. Before this mission, our knowledge of Mars was limited to telescope observations, where the planet was imagined as a lush environment that might harbor life. Mariner 4 unveiled a starkly different reality: a barren, cratered landscape devoid of life. President Lyndon B. Johnson declared, “It may just be that, as we know, it’s more unique than many people think, along with its humanity. We need to remember this.” The New York Times went even further.

Imagine life in the summer of 1965 if you hadn’t yet been born. In June, Ed White became the first American astronaut to walk in space. His experience was so profound that Soviet astronaut Alexei Leonov referred to it as “the saddest moment of my life” upon re-entering the capsule. Life Magazine celebrated White with a dedicated issue titled “A Glorious Walk in the Universe.” Shortly thereafter, images from Mariner 4 were broadcast, revealing Mars’s desolation. We had just entered a summer filled with dreams of the cosmos, a time of belief that we might not be alone; those dreams, however, were soon overshadowed.

Fast forward 60 years later, space and technology continue to captivate our attention. Spring was bustling with events. In April, the first all-female spaceflight led by then-fiance billionaire Jeff Bezos, Lauren Sanchez, launched using a rocket developed by Bezos’ Blue Origin. In May, another billionaire, Elon Musk, resigned amidst controversies surrounding Doge, all while sporting a “Occupied Mars” T-shirt.

In June, billionaire venture capitalist Peter Thiel shared in an interview with the New York Times, “Mars appears to be more than a science project. It’s a political undertaking.” By July, scientists presented findings at the National Astronomical Conference showing ancient riverbeds on Mars, challenging earlier beliefs regarding water on the planet. Sotheby’s auctioned a large piece of Martian meteorite for around $5.3 million (£4 million). Meanwhile, President Trump signed an executive order aimed at “preventing the federal government from overstepping.”

So, why create an opera about Mars? Because discussing Mars means exploring our own identities, aspirations for the future, and the mechanisms of current power dynamics.

To write the opera about Mars, how do we proceed? First, we select a script. The choice of author Mark O’Connell was natural; we are both intrigued by AI, Silicon Valley, and the ideological currents that permeate everyday life, from transhumanism and futurism to rising concerns around fertility rates in Western nations.

Our research dives deep, adopting a Hard Science Fiction perspective. We begin with everyday logistics. How do astronauts exercise, eat, shower, and use the restroom? Can a pregnancy be carried to term in zero gravity or under Mars’ weaker gravitational pull, which is 38% of Earth’s? The answers vary, ranging from the benign (using advanced resistance exercise equipment) to the concerning (one option involves tying a woman to an underground centrifuge during pregnancy).




“I turned to AI,” remarked Walche and her co-director Tom Creed during rehearsals. Photo: Ste Murray

The vast distance from Earth to Mars (about 140 million miles) complicates real-time communication. I pondered the dynamics of relationships in a scenario where conversations could only happen through audio notes. Each line of inquiry led to more questions: If we find life on another planet, how will it alter our understanding of ourselves and the cosmos? Is there a legal framework in place? Does the 1967 Outer Space Treaty hold? Are we humans destined to repeat the harrowing patterns of colonization, or can we carve a different path?

Our opera centers around an all-female mission. Four astronauts—Svetlana, Sally, Judith, and Valentina—named after the first four women in space, board the spacecraft Buckminster en route to Mars. Their quest is to find water to support existing colonies.

Their journey is arduous, further complicated by the scant entertainment options and reruns of *The Real Housewives of Beverly Hills*. Upon nearing Mars, they learn that their mission has become the target of a hostile takeover by Shadowfax Ventures, helmed by libertarian billionaire Axel Parchment. They now face isolation, the looming specter of corporate authoritarianism, and the existential question of alien life.

As we dived into the plot, the next challenge was to creatively encompass this expansive narrative acoustically. I envisioned the actual sounds astronauts would experience in different space environments: the roar of rocket propulsion, the hum of life support systems, and mechanical sounds. We meticulously analyzed audio recordings from the International Space Station, crafting ways to replicate these auditory experiences.

I immersed myself in hours of space audio—whistles, auroras, interstellar recordings from Voyager 1, and even humorous moments like Chris Hadfield’s lighthearted accounts of using the ISS restroom, alongside studies of various exoplanets. The community at Space Exploration Stack Exchange assisted with inquiries about musical instruments functioning in 38% gravity and the sound quality of trumpets and violins on Mars.

Interestingly, astronauts seem drawn to synth music. A playlist shared by Dutch astronaut Andre Kuipers revealed a taste for Vangelis, Mike Oldfield, and Brian Eno, leading me to incorporate synthesizers into both the orchestra and the spacecraft. For our antagonists, I leaned into AI to define their musical character, which was humorously labeled as “bad EDM.” They demonstrated a propensity for chaotic sounds, driving me to explore genres like “Bro Step” and “Fashwave.”

In our opera, the astronauts confront the challenges of a troubling future, resilient against the odds. Our vision, shaped by Mark’s and my imagination, captures not only resistance and hope but also moments of rebellion and joy. Throughout the summer, our team remained aware of the stark human challenges and anxieties outside the rehearsal space. This awareness drove us to explore the significance of our own world, amidst a perceived power dynamic favoring a select few wealthy individuals imposing their will on the greater populace.

This Year’s Weed Warrior: A Man’s Mission to Protect the Sonoran Desert

As Don Pike embarks on his daily stroll, he laces up his brown hiking boots, takes hold of his walking stick and bucket hat, and steps outside. A mere ten feet later, he skillfully navigates around barbed wire to enter the Tonto National Forest. Unlike the typical Tonto scenery, where the ground is strewn with dry grass between native plants and trees, this area feels stark, unfriendly, and barren.

The reason for this desolation is that Mr. Pike is engaged in weed removal.

“I’ve eliminated them so effectively that I can’t find any in this region,” remarked Pike, 84, a retired resident of Maine who has found great joy in his cherished desert and installed floor-to-ceiling windows in his living room.

Mr. Pike is in a battle against buffel grass and fountain grass, two invasive species that are spreading throughout the Sonoran desert. These plants suffocate native flora, elevate the risk and intensity of wildfires, and jeopardize a vibrant ecosystem.

His fight against this encroaching vegetation began nearly 15 years ago. Since then, he estimates he and his team of volunteers have cleared 550 acres of the approximately 14,000 acres they manage. In 2024, his efforts earned him the title of Arizona Weed Manager of the Year.

The work of volunteers like Pike has long been essential in supplementing federal land management, as government officials note that funding for their programs has been lacking for years. However, volunteers like Pike are becoming more crucial than ever given the reductions in federal workforce instigated by the Trump administration and its push for government efficiency.

“It will be vital for federal agencies to find innovative ways to attract individuals,” Pike stated from his back porch in March. “There are many who are eager to get involved, especially those with considerable skills.”

Soviet-era Spacecraft Poised to Re-enter Earth After Half a Century of Failed Venus Mission

A Soviet-era spaceship aims to land on Venus, with plans for it to return to Earth in the near future.

Currently, it is uncertain where the mass of half-ton metal will descend and how much will survive the journey. Experts are monitoring space debris.

Dutch scientist Marco Langbroek estimates that the spacecraft may re-enter Earth’s atmosphere around May 10th.

“There are risks involved, but there’s no need for excessive concern,” Langbroek stated in an email.

The object is relatively small, and even if it remains intact, the likelihood of it causing damage is similar to that of encountering a random meteorite fall, which occurs annually. “The chance of being struck by lightning in your lifetime is far greater,” he added.

He also mentioned that the spacecraft could potentially impact someone or something; however, this scenario cannot be entirely dismissed.

The Soviet Union sent the spacecraft, known as Cosmos 482, into orbit in 1972 as part of its Venus mission series. It never successfully launched from Earth orbit due to a rocket malfunction.

Most of its counterparts fell back within a decade, yet Langbroek and others believe the landing capsule, a spherical object about three feet (1 meter) in diameter, has been in a highly elliptical orbit for the past 53 years, gradually descending.

There is a substantial possibility that the over 1,000-pound (approximately 500 kilograms) spacecraft could endure re-entry. It was designed to withstand the harsh conditions of Venus’ atmosphere, which is thick with carbon dioxide, according to Langbroek from Delft University of Technology in the Netherlands.

Experts are skeptical about the longevity of its parachute system. Additionally, heat shields might have deteriorated over extended periods in orbit.

Jonathan McDowell of the Harvard Smithsonian Astrophysical Observatory mentioned in an email that while the spacecraft would benefit from an intact heat shield, if it manages to re-enter successfully, “a half-ton metal object will be falling from the sky.”

The spacecraft is projected to re-enter around 51.7°N and 51.7°S, passing near London, Edmonton, Alberta, and Cape Horn, South America. However, given that much of the Earth is covered by water, “the chances are favorable.”

Inside the Mission Where He Captured His First Video of a Giant Squid

As it emerged, it was yet another journey into the abyss, cloaked in darkness: mid-water, a delicate, ethereal shape transitioning into another realm.

A remotely operated vehicle, Subathian, recorded the first footage of a giant squid stable in its natural habitat in the southern ocean near Antarctica. The giant squid can grow up to 10 meters (33 feet) in length, making it the heaviest invertebrate on the planet, yet until now, it remained elusive.

This remarkable discovery occurred during a 35-day expedition to the Southern Sandwich Islands, a secluded volcanic arc in the Southern Ocean, aboard the Folcole (too).

The expedition aimed to expedite the discovery of deep-sea species, but nobody anticipated encountering one of the ocean’s most elusive giants.

“We were operating Subathian at a depth of about 2,000 meters that day for trench work,” stated Dr. Michelle Taylor, Chief Scientist of the Expedition and Senior Lecturer at Essex University, as reported by BBC Science Focus.

While Subathian navigated through the cerulean waters, we remained in the control room, surrounded by high-resolution cameras and screens displaying sensor data from the vehicle. A group of scientists observed intently as we monitored the water column.

https://www.youtube.com/watch?v=lzpog9h8hlo

On March 9th, at a depth of approximately 600 meters (nearly 2,000 feet), the pilot spotted something and began to hover.

“None of us aboard were squid specialists, but we quickly recognized it as a stunning glass squid,” Taylor recounted. “We documented it for about three minutes before resuming our mission to explore the ocean floor.”

The giant squid is among the planet’s most enigmatic creatures. Until now, they had only been seen as dead specimens—either accidentally caught by fishing boats or found in a whale’s stomach. Documenting a living specimen is akin to discovering a unicorn in marine biology.

Furthermore, the squid was not yet fully grown. “It was a juvenile,” Taylor explained. “It lacked some physical features of adult squid, but it was definitely not fully developed. Its size was quite modest for a giant squid.”

The footage streamed live on YouTube during the dive was initially flagged by audience members.

Taylor consulted with Dr. Kat Bolstad, a cephalopod expert at Auckland Institute of Technology, along with other colleagues, who confirmed their identification with the aid of the 4K video footage captured during the dive.

Telltale clues included a distinctive hook along the squid’s arm.

“[Knowing it’s a colossal squid], I find it both beautiful and extraordinary,” Taylor remarked.

While the giant squid garnered headlines, it was not the singular highlight of the Folcole (too) expedition. About a month ago, researchers also captured the first in situ footage of a glacial glass squid.

Both sightings resulted from lengthy, meticulous dives conducted by Subathian, which can descend up to 4,500 meters (3 miles), enhancing the role of “telepresence” in scientific exploration.

This is the first confirmed footage of a glacier glass squid captured in January – Rov Subathian/Schmidt Ocean Institute

“It’s a new milestone, bringing the world into the deep sea in ways that were once impossible,” Taylor states. “Science enthusiasts and the general public can engage directly with our findings, often possessing extensive knowledge about what we observe.”

Taylor emphasizes that the mission’s deeper purpose transcends mere discovery; it aims to enhance the understanding and protection of deep-sea life.

“This is the last frontier,” she emphasizes. “It’s perplexing why we pursue other planets when we barely comprehend our own oceans.”

The Ocean Census seeks to expedite the discovery of new species, yet this process remains painstakingly slow. Often, it takes over a decade from specimen collection to formal recognition.

In its initial years, the project has already documented more than 800 new species, focusing on uncharted areas and fostering collaboration with a global network of taxonomists.

The sighting of the giant squid may have been serendipitous, but for Taylor, it marks merely the beginning.

“There is still much left to discover,” she asserts.

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.

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.

Deimos looks dark surrounded by Mars

ESA

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.

NASA’s Spherex set to launch after delays, will map 450 million galaxies on mission

The new NASA Observatory was launched into space on Tuesday with a mission that would help scientists unravel what happened in the first fraction one second after the Big Bang.

The Spherex mission (short for Universe History, Reionization Epoch, Ice Explorer’s Spectroscopic Optical Meter) is designed to map the entire sky, study millions of galaxies, and stitch together how the universe has formed and evolved.

According to NASA, it has been postponed several times since late February to help engineers evaluate the rocket and its components recently due to bad weather at launch sites.

The cone-shaped spacecraft ended Tuesday at approximately 8:10pm above the Space Sex Falcon 9 rocket from Van Denburg Space Force Base in California. Also, to get into orbit there were four suitcase-sized satellites deployed on another mission by NASA to study the sun.

The $488 million Spherex Observatory will investigate the entire sky four times over a two-year mission. Spacecraft instruments observe the universe in 102 different colors or wavelengths.

The Spherex Observatory, located horizontally, allows you to see all three layers of photon shields and telescopes.
BAE System / NASA

Colors in the infrared range have longer wavelengths than what the eye sees, so they are essentially invisible to humans. However, in the universe, infrared light from stars, galaxies and other celestial bodies contains important information about composition, density, temperature and chemical composition.

A technique known as spectroscopy allows scientists to analyze infrared light and divide it into different colors, just like the way prisms divide sunlight into colorful rainbows. Therefore, data collected by the Spherex Observatory gives researchers insight into the chemistry and other properties of hundreds of millions of galaxies in the universe.

NASA said these observations would help scientists study how galaxies are formed, trace the origins of Milky Way waters, and connect what happened later. The Big Bang that Created the Universe Approximately 13.8 billion years ago.

NASA to launch Spherex Space Telescope for Sky Scanning Mission

Impressions of the artists of Spherex Space Telescope

NASA/JPL-Caltech

The latest addition to NASA's Space Telescope Fleet will be launched this weekend and will soon scan the entire sky in near-infrared wavelength ranges, collecting a wealth of data on more than 450 million galaxies.

The history of the universe, the reionization epoch, and the spectrophotometer for Ice Explorer (Spherex) will be released on March 2nd on a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California at 10:09 pm local time.

It carries a camera with filters that divide the light that enters like a prism and beams different parts of the spectrum into 102 separate color sensors. As the telescope pans around the sky, it slowly tightens the full image pixels pixel by pixel. This strategy allows you to use a relatively small and simple camera to do what you need to have a heavy, expensive suite of sensors, even without moving parts.

“If you slowly scan the sky slowly by moving the telescope, after a sufficient amount of time, every pixel in the sky is observed over a very wide wavelength range, giving you a coarse spectrum of every bit of the sky that has never been done before.” Richard Ellis University College London. “It's a very small space telescope, but it has some very unique features.”

Ellis says this rich dataset allows for accidental discoveries. “There's a high chance that you'll find something unexpected,” he says.

Infrared data is outside the human vision range, allowing scientists to determine the distance of objects and learn how to form galaxies. It can also be used to determine the chemical composition of an object, potentially revealing the presence of water and other important components.

The interesting stuff thrown by Spherex can be investigated in a more focused way using NASA's existing space telescope fleet.

Christopher Conseris At the University of Manchester in the UK, Spherex says it doesn't match the JWST solution or create similarly adoring images, but it says it will become a “maintainer” for scientific discovery.

“JWST can point to a part of the sky and take some big photos [and reveal] Something completely new. And Spherex really can't do the same thing,” he says. “It's going to be an analysis that takes years, and it's going to cover the sky many times.”

Spherex orbits the Earth 14.5 times a day away from the Earth's surface, completing 11,000 orbits over a two-year lifespan. Three cone-shaped shields protect the instrument from the Earth's radiant heat and interference from the sun.

The same rocket will be released on the polarimeter, another NASA mission to unify the Corona and Heliosphere Fair (punch), which will study the solar winds of the sun.

Athena, the intuitive moon lander machine, poised for explosive mission on the lunar surface

Artist's impression of the moon's Athena spaceship

NASA

This week, a private space mission was launched on the moon, aiming to reach the southernmost point we've ever visited on the moon. The Athena spacecraft, built by an intuitive US-based machine, will be released from NASA's Kennedy Space Center in Cape Canaveral, Florida at 12:17am on February 27th (7:17pm on February 26th). It will be installed on the SpaceX Falcon 9 rocket. Also, several other missions hitch on the same rocket, including expeditions that mine asteroids.

The intuitive machine became the first private company to succeed on the moon last year when Odysseus' spacecraft landed near the moon's Antarctica. The spacecraft's instruments remained in operation, but Odysseus made a troublesome landing, flipped over, limiting the amount of data the equipment could collect, and shortening the mission.

The company hopes for a cleaner landing as Athena begins its descent towards the end of March. The planned landing site is near the highest mountain on the moon, the lunar mewton, about 60 kilometers from Antarctica, and Athena's attempts have become the most southern approach to date. If the ship is successful, it will start a moon night and operate for several weeks on par with the moon in a day before it loses power.

Athena carries over 10 musical instruments and missions from both NASA and other private companies. That's not all. The Falcon 9, the same one that fires Athena at the moon, also carries three unrelated spacecraft. These are asteroid-controlled spacecraft from space company Astroforge, and the first mission of this kind will investigate potential minable metal space rocks later this year. You can also map water to the moon along with NASA's lunar satellite aboard, looking for future landing sites. The third spacecraft, built by epic aerospace, is designed to help other satellites move between orbits.

Once Athena lands, NASA instruments will excavate up to 1 meter into the lunar soil to sample it, then look at water sediments and other chemicals. NASA would like to know if these will be present in sufficient quantities for future astronauts to be used as part of the Artemis Moon Landing, which is planned for the agency to be released in 2027. It's there.

Several small rovers will also be released near the landing site, including the plant pot-sized Yaokirovers of Japanese company Dimon. The heavier 10kg mobile autonomous exploration platform (MAPP), built by Space Company Lunar Outspost, explores and creates 3D maps of landing sites, testing how the 4G phone network built by Nokia works in a Lunar environment. Masu. Sitting on a mapp will be a much smaller, ant-sized robot built by researchers at the Massachusetts Institute of Technology.

The intuitive machine deploys a suitcase-sized hopping robot called Grace. Grace runs a series of four hops, jumping into the air up to 100 meters, travelling a distance of about 200 meters until it lands in a deep, permanently shaded crater. Scientists have seen evidence that these areas do not get warmer than -170°C (-274°F), but have never been visited in person. Grace scans the bottom of this crater. This crater is scanned for about 45 minutes, about 20 meters below, before popping out again.

Gaia Announces Most Detailed Map of Milky Way to Date, Achieves Skyscan Milestone in Mission

Released on December 19, 2013, ESA's star mapping satellite “Gaia” We are now nearing the sky, but this does not mean the mission is complete. Technical tests are scheduled in the weeks before Gaia moves into its “retirement” orbit, with two major data releases scheduled for around 2026 and the end of the century, respectively.

ESA Director of Science Carol Mandel said: “Today, as the science observations conclude, we celebrate this amazing mission that has exceeded all our expectations, extending almost twice its original predicted lifetime.” said.

“The treasure trove of data collected by Gaia has given us unique insight into the origin and evolution of the Milky Way galaxy, and has also provided insight into astrophysics and the solar system in ways we still don't fully understand. It transformed science.”

“Gaia is built on Europe’s unique excellence in astronomical measurements and will leave a lasting legacy for future generations.”

“After 11 years in space, surviving micrometeorite impacts and solar storms along the way, Gaia has completed collecting scientific data,” said Gaia project scientist Johannes Sahlmann.

“All eyes are now on preparing for the next data release.”

“We are excited to carry out this incredible mission and are excited about the discoveries that await us.”

Gaia has used the three instruments many times over the course of its mission to observe and chart the stars' positions, distances, movements, changes in brightness, compositions, and numerous other characteristics.

This will allow Gaia to achieve its primary goal of building the largest and most accurate map of the Milky Way, displaying our home galaxy like no other mission has been able to achieve to date. is completed.

“Gaia has changed our impression of the Milky Way, so it contains major changes from previous models,” said Stefan Payne Waldenaar, a science visualizer at the House of Astronomy and the IAU Directorate of Astronomy Education. said.

“Even basic ideas such as the rotation of the galaxy's central bar, the distortion of the disk, the detailed structure of the spiral arms, and the interstellar dust near the sun have been revised.”

“Still, we are still speculating about the distant parts of the Milky Way based on incomplete data.”

“As more Gaia data is released, our view of the Milky Way will become even more accurate.”

Gaia's science and engineering teams are already hard at work preparing for Gaia Data Release 4 (DR4), scheduled for 2026.

The amount and quality of data is increasing with each release, and Gaia DR4, with an expected 500 TB data product, is no exception.

Additionally, it will cover the first 5.5 years of the mission, which is the length of the mission as originally planned.

“This is the release of Gaia that the community has been waiting for, but it's exciting considering it only covers half of the data collected,” said Dr. Antonella Valenari, an astronomer at the National Institute of Astronomical Sciences. Ta.

“Although the mission is currently suspending data collection, it will be business as usual for many years to come as we continue to make these impressive datasets available.”

Over the past decade, Gaia has accumulated more than 3 trillion observations of nearly 2 billion stars and other astronomical objects, revolutionizing the way we see our home galaxy and neighboring universe, and advancing its mission. You have completed the empty scan stage. Image credit: ESA / Gaia / DPAC / Stefan Payne-Wardenaar.

After several weeks of testing, Gaia will leave its current orbit around Lagrangian Point 2, 1.5 million km from Earth, away from the Sun and be placed into a final heliocentric orbit far from Earth's sphere of influence. .

The spacecraft is scheduled to be passivated on March 27, 2025 to avoid harm or interference with other spacecraft.

During the technical test, Gaia's orientation is changed, temporarily making it several orders of magnitude brighter and making it much easier to observe with small telescopes.

Gaia mission manager Uwe Lammers said: “Gaia will shine among the stars before her sad retirement and will treat us with this final gift to bid her farewell.”

“This is a moment to celebrate this transformative mission and to thank all the teams who have worked hard for more than a decade to operate Gaia, plan observations, and ensure the smooth return of valuable data to Earth.”

European Clipper mission to Jupiter’s icy moons launched by NASA

For decades, Jupiter’s icy moons have been considered one of the most promising places in the solar system to search for extraterrestrial life. Europa, thought to have an underground ocean and a potentially habitable environment, has long been considered an attractive target in our cosmic backyard.

Now humans are ready to take a closer look at Jupiter’s fourth largest moon.

NASA is scheduled to launch a new robotic mission to Jupiter as soon as noon Monday. The probe, named Europa Clipper, is the largest spacecraft the company has ever built for a planetary science mission.

Assuming no further launch delays, Europa Clipper is scheduled to lift off Monday at 12:06 pm ET aboard a SpaceX Falcon Heavy rocket from NASA’s Kennedy Space Center in Florida.

The launch was originally scheduled for Thursday, but NASA was forced to cancel due to Hurricane Milton, which made landfall late Wednesday near Siesta Key along Florida’s west coast. Kennedy Space Center was closed as the storm battered the state, bringing high winds and heavy rain to much of the Florida peninsula.

The delay was a minor setback in a mission that took more than a decade to plan and develop.

“It feels surreal,” said Jordan Evans, mission project manager at NASA’s Jet Propulsion Laboratory. “There were battles at every level, from the early stages of the initial concept of the mission, to getting approval, passing each milestone and overcoming various problems along the way. At this point, the team was ready. It’s incredible to watch.”

Europa Clipper is not embarking on a life-detecting mission. Rather, they will study the composition of the icy moon, as well as its internal structure and geology. This information could help scientists determine whether Europa currently has the right ingredients to support life, or whether they existed at some point.

“We’re looking for a habitable environment,” said Bonnie Blatty, mission deputy project scientist at the Jet Propulsion Laboratory. “We believe that liquid water is a necessity for life, and that it exists. Whether through active geology or something else, we need the right chemistry to act like a battery to propel life. It’s energy.”Parallel.”

Blatty said there is strong scientific evidence that a vast ocean lurks beneath the moon’s icy surface. In fact, Europa’s interior ocean is estimated to be twice the volume of all of Earth’s oceans combined, according to NASA.

A mosaic image of Jupiter’s moon Europa acquired by a camera aboard NASA’s Galileo spacecraft on November 25, 1999.
NASA

Europa Clipper is scheduled to enter Jupiter’s orbit in 2030 after a six-year, 1.8 billion mile journey.

The 49 flybys of the moon over four years will provide researchers with new insights.

“We’ll definitely be able to tell how thick the ice crust is and whether there are small ponds there,” Blatty said. “As for the ocean, I think we will someday find out how deep it is.”

To make these observations, the spacecraft will fly through a harsh radiation environment created by Jupiter’s massive magnetic field, which NASA says is about 20,000 times stronger than Earth’s.

“If we were to go into orbit around Europe and do research, even the most radiation-resistant electronic equipment would likely be destroyed by radiation within a month or two,” Evans said. said.

Instead, mission managers developed a way for the probe to orbit Jupiter in harmony with the icy moon. This is a kind of cosmic duet that could help protect equipment from prolonged exposure to harsh radiation.

“So every six times Europa orbits Jupiter, or every 21 days, we’ll be at a precise position in space, right next to Europa,” Evans said. “And because each flyby will be different, we will be able to cover almost the entire world’s moon.”

However, the team will need to exercise patience. Before reaching Jupiter, the spacecraft will first pass Mars and then circle Earth again, using the gravity of both planets to blast it deep into space.

Europa was discovered in 1610 by Italian astronomer Galileo Galilei. This icy object is the fourth largest of Jupiter’s 95 known moons.

Several space probes have previously observed Europa, including NASA’s Voyager 1, Voyager 2, and Galileo missions, but this will be NASA’s first dedicated mission to the Moon, and will be the first mission for NASA to go beyond Earth. This will be my first time researching the ocean world.

This milestone has been a long time coming for Blatty, who wrote a paper on Europa as a graduate student at Cornell University in the 1980s.

“I’ve actually only been in this role for two and a half years. I didn’t start it,” she said. “But I’m so happy to be back to something so near and dear to my heart. It’s truly a dream.”

SpaceX Crew Makes History with First ‘Stand-Up’ Private Spacewalk During Polaris Dawn Mission

Jared Isaacman looks out the hatch of the Dragon capsule.

SpaceX

SpaceX made history today when its private astronauts conducted the first-ever private spacewalk as part of the Polaris Dawn mission.

As SpaceX's Crew Dragon spacecraft orbited Earth at an altitude of about 740 km at a speed of more than 25,000 km per hour, the two astronauts partially ejected from the spacecraft, one at a time.

The four-man crew began evacuating the cabin at 10:31 GMT, eventually manually opening the hatch at approximately 10:50 GMT. All crew members were wearing new SpaceX spacesuits that have been thoroughly tested on Earth but not in orbit.

Jared Isaacman, the mission commander, head of SpaceX's Polaris program and billionaire co-financier, was the first person to step out of the spacecraft and look down at Earth. “It certainly is a perfect world from up here,” Isaacman said, lifting his head and torso from the capsule.

Isaacman then went through a series of suit mobility and safety checks before returning to his seat in the spacecraft a few minutes later, after which Crew Dragon fired its thrusters to maintain an optimal orbit and SpaceX engineer Sarah Gillis performed a spacewalk.

Neither Isaacman nor Gillis fully exited the spacecraft, making the event technically a stand-up extravehicular activity (SEVA) rather than a full spacewalk. Previous SpaceX promotional materials for the mission stated: Astronauts completely exit the capsule.

While all previous spacewalks to date have been conducted by government-trained astronauts, the Polaris Dawn crew will be all civilians: along with Isaacman and Gillis are retired U.S. Air Force test pilot Scott Poteet and SpaceX engineer Anna Menon.

Isaacman also took part in SpaceX's groundbreaking flight in 2021, which was the first orbital spaceflight with only private citizens on board. That flight used the exact same Crew Dragon spacecraft as the latest mission.

SpaceX's Polaris Dawn mission is reminiscent of earlier space programs of the 1960s and 1970s because the Crew Dragon capsule does not have an airlock, making it one of the most dangerous spacewalks ever attempted.

Once SEVA is complete, the remainder of the mission will see the crew spend up to two more days in orbit before returning to Earth.

First private spacewalk launched by SpaceX’s Polaris Dawn mission

Polaris Dawn launch

SpaceX

SpaceX launched the Polaris Dawn mission to attempt the first-ever private spacewalk, and one of the most dangerous spacewalks ever attempted.

The four-person crew will spend up to five days in Earth orbit, with two crew members performing an extravehicular activity (EVA) on the third day. During this EVA, the spacecraft will be depressurized for about two hours. The two remaining crew members will also need to wear space suits.

This is different from other modern spacewalks, which typically use an airlock to seal the craft off the vacuum of space while the astronauts are outside. The Crew Dragon capsule used in this mission has no airlock, making it more similar to the early days of spaceflight in the 1960s and 1970s. Additionally, all previous spacewalks have been conducted by government-trained astronauts, while the Polaris Dawn crew is civilian.

Although the spacesuits have been thoroughly tested on Earth, they are a new design, and the risks are compounded by the fact that the flight will be farther from Earth than any other human spaceflight since the end of the Apollo program in 1972.

The flight’s mission commander is SpaceX’s Polaris program chief and billionaire co-founder Jared Isaacman. The rest of the crew is retired Air Force test pilot Scott Poteat and SpaceX engineers Sarah Gillis and Anna Menon.

The Crew Dragon capsule used on this flight was named “Resilience” and was its third launch aboard a Falcon 9 rocket. The reusable Falcon 9 first stage returned to Earth and landed on SpaceX’s Just Read the Instructions drone over the Atlantic Ocean.

SpaceX’s Crew Dragon capsules are also used to transport astronauts and supplies to and from the International Space Station, and one of them is scheduled to return NASA astronauts Butch Wilmore and Sunita Williams to Earth in early 2025 after they were stranded when their launch vehicle, the Boeing Starliner, encountered problems.

For the First Time, NASA’s Endurance Mission Measures Earth’s Bipolar Electric Field

First hypothesized over 60 years ago Bipolar electric field Polar winds are the primary driver of a constant outflow of charged particles into space above the Earth’s poles. These electric fields lift charged particles in the upper atmosphere to higher altitudes than usual, and may have shaped the evolution of Earth in ways that are still unknown.



Collinson othersThey report that a potential drop of +0.55 ± 0.09 V exists between 250 km and 768 km due to the planetary electrostatic field, generated solely by the outward pressure of ionospheric electrons. They experimentally demonstrate that the Earth’s ambipolar field controls the structure of the polar ionosphere, increasing its scale height by 271%. Image courtesy of NASA.

Since the 1960s, spacecraft flying over Earth’s poles have detected streams of particles streaming from Earth’s atmosphere into space.

Theorists predicted these outflows, named them polar winds, and stimulated research to understand their causes.

Some outflow from the atmosphere was expected — intense, unobstructed sunlight should send some atmospheric particles escaping into space, like water vapor evaporating from a pot of water — but the observed polar winds were more puzzling.

Many of the particles inside were cold and showed no signs of heating, but they were moving at supersonic speeds.

“Something must be attracting these particles to the outer reaches of the atmosphere,” said Dr. Glynn Collinson, Endurance mission principal investigator and a researcher at NASA’s Goddard Space Flight Center.

The electric fields, hypothesized to be generated at subatomic levels, would be incredibly weak and their effects would be expected to be felt only for distances of hundreds of miles.

For decades, detecting it has been beyond the limits of existing technology.

In 2016, Dr Collinson and his colleagues began inventing a new instrument that they thought would be suitable for measuring Earth’s bipolar magnetic field.

The team’s equipment and ideas were perfectly suited for a suborbital rocket flight launched from the Arctic.

The researchers named the mission “Antarctic Expedition,” in honor of the ship that carried Ernest Shackleton on his famous 1914 Antarctic voyage. Endurance.

They set course for Svalbard, a Norwegian island just a few hundred miles from the North Pole and home to the world’s northernmost rocket launch site.

“Svalbard is the only rocket launch site in the world that can fly through the polar winds and make the measurements we need,” said Dr Susie Ingber, an astrophysicist at the University of Leicester.

Endurance was launched on May 11, 2022, reaching an altitude of 768.03 kilometers (477.23 miles) and splashing down in the Greenland Sea 19 minutes later.

Over the 518.2 kilometres (322 miles) altitude where Endurance collected data, it measured a change in electrical potential of just 0.55 volts (V).

“Half a volt is almost meaningless – it’s about the strength of a watch battery – but it’s just right for describing polar winds,” Dr Collinson said.

Hydrogen ions, the most abundant type of particle in the polar wind, experience an outward force from this field that is 10.6 times stronger than gravity.

“That’s more than enough to counter gravity, in fact to launch you into space at supersonic speeds,” said Dr. Alex Grosser, a research scientist at NASA’s Goddard Space Flight Center and Endurance project scientist.

Heavier particles are also accelerated: an oxygen ion at the same altitude, immersed in this 0.5 volt electric field, loses half its mass.

In general, scientists have found that bipolar magnetic fields increase what’s called the scale height of the ionosphere by 271%, meaning the ionosphere remains denser up to higher altitudes than it would be without the bipolar magnetic field.

“It’s like a conveyor belt that lifts the atmosphere up into space,” Dr Collinson said.

The Endurance discovery has opened up many new avenues of exploration.

The polarity field, as a fundamental energy field of the Earth alongside gravity and magnetism, may have continually shaped the evolution of the atmosphere in ways that we are only now beginning to explore.

Because it is generated by the internal dynamics of the atmosphere, similar electric fields are expected to exist on other planets, including Venus and Mars.

“Any planet with an atmosphere should have a bipolar magnetic field, and now that we’ve finally measured it we can start to learn how it has shaped our planet and other planets over time,” Dr Collinson said.

SpaceX delays launch of private Polaris mission for second time

SpaceX has once again delayed the launch of its Polaris Dawn mission, which was supposed to take four private citizens into space, this time citing bad weather forecasts.

The company attributed the postponement to adverse weather conditions off the Florida coast, without specifying whether their main concern was the potential impact on the spacecraft’s water landing in case of an emergency or the safety of the crew during their return home after the five-day journey.

Billionaire entrepreneur Jared Isaacman, retired Air Force Lt. Col. Scott Kidd, and SpaceX engineers Sarah Gillis and Anna Menon are set to launch early on Wednesday for what will be the first all-civilian crew spacewalk.

Isaacman noted in a post on X that the Polaris Dawn mission will face significant limitations due to the expected splashdown conditions as the capsule will not dock with the International Space Station, and astronauts might have to wait for improved weather conditions.

“With no ISS rendezvous and limited life support supplies, it’s crucial for us to verify re-entry weather conditions before the launch,” he stated.

Alternate launch dates were initially set for Thursday, but SpaceX canceled both launches due to the weather outlook. The company has yet to announce new launch dates.

“The team will continue monitoring the weather for favorable launch and return conditions,” SpaceX shared on X.

An earlier launch attempt on Tuesday was called off after a helium leak was detected on the launch pad.

In addition to attempting the first all-civilian spacewalk, Polaris Dawn aims to reach the highest orbital altitude humans have reached since the final Apollo moon mission in 1972. The mission will also test new spacesuits and other technologies for future long-duration expeditions, potentially providing valuable research to support SpaceX’s long-term goal of launching missions to the Moon and eventually Mars.

First private spacewalk to be featured in SpaceX’s Polaris Dawn mission

A groundbreaking space mission known as Polaris Dawn is set to take off next week with four private citizens on board. The mission is expected to feature the first ever spacewalk conducted entirely by a civilian crew.

The commander of the mission is billionaire entrepreneur Jared Isaacman, who is also the founder and CEO of Shift4, a payment processing company. Polaris Dawn is the first of three spaceflights funded and organized by Isaacman in collaboration with SpaceX, collectively known as the Polaris Program. This will be the first private SpaceX mission to reach orbit in 2021.

The crew of three includes pilot Scott Kidd-Poteet, a retired Air Force Lt. Col., and SpaceX engineers Sarah Gillis and Anna Menon. They will be venturing into space aboard SpaceX’s Crew Dragon capsule on a Falcon 9 rocket for a planned five-day mission.

One of the highlights of the mission will be a spacewalk on the third day, where two crew members will exit the capsule via cables and spend up to 20 minutes in space. This is a historic moment as until now, spacewalks have been carried out exclusively by astronauts from government space agencies.

During the spacewalk, the Crew Dragon capsule will be fully exposed to the vacuum of space at an altitude of 435 miles above Earth. To prepare for this event, all four astronauts will don SpaceX-designed spacesuits for testing and future long-duration missions.

The mission aims to inspire people to dream big and push the boundaries of human exploration beyond Earth. The crew, including Isaacman, have undergone extensive training over the past two years in preparation for this momentous journey.

In addition to conducting science experiments and testing technology during the mission, the crew will also raise funds for St. Jude Children’s Research Hospital, continuing Isaacman’s philanthropic efforts in space.

Details regarding the cost, objectives, and timeline of future Polaris flights have not been disclosed by Isaacman at this time.

Plans explained by Polaris mission commander

summary

  • SpaceX is gearing up for its next private mission scheduled for August 26, which will mark the company’s inaugural spacewalk endeavor.
  • The crew of four includes billionaire Shift4 founder Jared Isaacman, his colleague Scott Poteat, and SpaceX employees Anna Menon and Sara Gillis.
  • The Polaris Dawn mission is the first of three flights purchased by Isaacman from SpaceX.

SpaceX is getting ready to launch its next private mission by the end of this month, which will be its first attempt to send astronauts into space.

Polaris Dawn Mission — Billionaires and Shift 4 Founder Jared Isaacman Purchased from SpaceX in 2022 The spacecraft, the final mission of the human spaceflight program known as Project Polaris, is scheduled to lift off from Florida in the early hours of August 26th.

“We don’t have the freedom to launch whenever we want,” Isaacman said. “It was pretty close to dawn, which is very appropriate given the mission.” CNBC’s Space Investments In an interview last month.

Isaacman said, Historic Inspiration 4 Flights in 2021 He will again lead a four-person crew, with longtime colleague Scott Poteat joining as pilot, and SpaceX employees Anna Menon and Sara Gillis serving as the flight’s medical director and mission specialist, respectively.

The multi-day journey won’t be a destination-specific one, but rather a free-flight mission on an orbit that will hopefully take the crew far from Earth.

“We will be reaching much higher altitudes than any human has reached in over 50 years,” Isaacman said.

But the highlight of Polaris Dawn will be its planned spacewalks.

Extravehicular activities (EVAs) have been a routine part of NASA astronaut missions for years, such as when the space agency needs to perform maintenance outside the International Space Station, but no private company has ever attempted an EVA until now.

Isaacman said he understood that the spacewalk would mean he and his crew would be “surrounded by death,” and he was ready to embrace the moment. I have been thoroughly trained.

“The only thing that comes close to that is a vacuum chamber. It almost feels like being in a vacuum or in space. … You can actually feel the pressure changes, the temperature changes and the psychological stress of being in a very hostile environment,” Isaacman said.

Five-day mission planning

Isaacman also detailed Polaris Dawn’s daily schedule, which will remain in space for up to five days.

The first day will be all about finding the time when the risk from micrometeorite orbital debris is minimal, which will determine the exact time for Polaris Dawn to launch. After reaching the 190-kilometer by 1,200-kilometer orbit, the crew will conduct a thorough checkout of SpaceX’s Dragon spacecraft Resilience, Isaacman said.

“It’s really important to make sure there are no defects in the aircraft before we go up to an altitude of 1,400 kilometers,” Isaacman said.

The spacecraft also traveled through what are known as high radiation zones. South Atlantic Anomaly.

“Ideally we want to get as low as possible because even at 200 kilometres the radiation levels are quite high,” Isaacman said. “Two or three high-altitude passes through the South Atlantic Anomaly will account for nearly the entire radiation load of the mission, equivalent to three months on the International Space Station.”

The second day will focus on some of the scientific research Polaris Dawn plans to accomplish, with a total of about 40 experiments. The crew will also prepare for the spacewalk and test their spacewalk suits.

“That way we can make sure there’s nothing unexpected happening in microgravity compared to what we could test on Earth,” Isaacman said.

Day 3 is the big day – spacewalk.

Spacewalk

So who on the crew will be doing the spacewalk?

“It’s fair to say that all four of us are working together. There’s no airlock, there’s a vacuum inside the spacecraft,” Isaacman said.

Two of the crew members (Isaacman and Gillis) will travel outside of Dragon, while Poteet and Menon will remain on board as support.

The spacewalk is expected to take two hours from start to finish, and Isaacman stressed that it is “really a test and development” process.

“We want to learn as much as we can about the spacesuit and its operation, but there is a finite amount of oxygen and nitrogen available,” Isaacman said.

Polaris Dawn will livestream the spacewalk, and mission commanders stressed that there will be “multiple cameras” inside and outside the capsule.

Brand new space suit

A key piece of equipment that makes EVA possible is SpaceX’s spacesuit.

For the past few years, the company has been using its minimalist, black-and-white IVA suits (Internal Vehicle Activity suits, or IVA suits worn by astronauts in emergencies) to develop its EVA suits, which Isaacman said are the result of hundreds of hours of testing different materials over the years.

“So our main goal is to learn as much as we can about the suit,” Isaacman said.

“It’s all about building the next generation of spacesuits. We continue to refine the design of this suit so that SpaceX can manufacture hundreds and thousands of suits in the future for operations on the Moon, Mars and in space. [low Earth orbit]”, and many other things. Building a new spacewalk suit is no easy task,” he added.

Polaris Dawn aims to push the boundaries of private spaceflight, and Isaacman hopes the mission will be inspiring, just like his first orbital flight.

“That’s the inspiration aspect. Anything that’s different from what we’ve seen in the last 20 or 30 years excites people and makes them think, ‘If this is what I’m seeing today, what will it be like tomorrow or a year from now?'”

352 new binary asteroid candidates discovered by ESA’s Gaia mission

Binary asteroid systems have attracted the attention of the scientific community due to their intriguing properties and significant impact on our understanding of the Solar System. Unlike single asteroids, binary systems provide unique insights into many fundamental processes, including planetary formation and evolution, collision dynamics, and gravitational interactions.

Asteroids are fascinating celestial objects that hold unique insights into the formation and evolution of our solar system.

Binary stars are even more fascinating because they allow astronomers to study how different objects in the universe form, collide, and interact.

With our unique all-sky scanning function, ESA's Gaia satellite Since its launch in 2013, it has made a number of important asteroid discoveries.

In Data Release 3, Gaia pinpointed the positions and movements of more than 150,000 asteroids. That precision has allowed scientists to probe deeper, looking for asteroids that exhibit a characteristic “wobble” caused by the gravitational pull of their orbiting companion stars.

Gaia has also collected data on the asteroid's chemistry, compiling the largest ever collection of asteroid reflectance spectra – light curves that reveal an object's color and composition.

More than 150,000 orbits determined in Gaia's Data Release 3 were refined as part of the mission's Focused Product Release last year, making them 20 times more accurate.

Gaia's upcoming Data Release 4 (due after mid-2026) is expected to reveal the orbits of even more asteroids.

“Binary asteroids are difficult to find because most are very small and far away from Earth,” said Dr Luana Liberato, an astronomer at the Observatory of the Côte d'Azur.

“Although just under one in six asteroids are predicted to have companion stars, only half a billion of the one million known asteroids have been found to be in binary systems.”

“But this discovery shows that there are many more asteroid moons still waiting to be discovered.”

“If confirmed, this new discovery adds 352 potential binary systems, nearly doubling the known number of moon-bearing asteroids.”

“Gaia is proving to be an excellent asteroid explorer, working hard to unlock the secrets of the universe, both within our solar system and beyond,” said Dr Timo Prusti, ESA's Gaia project scientist.

“This discovery highlights the Gaia data release as a major improvement in data quality and demonstrates the incredible new science made possible by this mission.”

An Ambitious New Space Mission on a Collision Course with an Approaching Asteroid

To prevent a fate similar to the dinosaurs, The European Space Agency (ESA) has initiated work on a groundbreaking planetary defense mission known as the Rapid Apophis Mission for Space Security (RAMSES).

RAMSES is designed to rendezvous with 99942 Apophis, an asteroid the size of a cruise ship, and accompany it as it approaches Earth in April 2029.

Apophis, with a diameter of about 375 meters, will pass within 32,000 kilometers of Earth’s surface on April 13, 2029. This rare event will be visible to the naked eye in parts of Europe, Africa, and Asia, attracting global attention. An asteroid of this size only comes this close once every 5,000 to 10,000 years.


undefined


Astronomers believe that Apophis is unlikely to collide with Earth in the next 100 years, but the 2029 flyby will provide scientists with a unique opportunity to observe a close encounter.

The ESA’s Ramses spacecraft is set to reach Apophis two months before the closest approach, allowing monitoring of any physical changes to the asteroid caused by Earth’s gravity.

Ramses is scheduled to launch in April 2028 and arrive at Apophis by February 2029. The mission aims to observe and study how Earth’s gravity affects Apophis, potential landslides, and any new material beneath the asteroid’s surface.

Patrick MichelGerry McClellan, CNRS Director of Research at the Observatory of the Côte d’Azur, emphasized the significance of the mission, stating: “There is much we still don’t know about asteroids, but now, nature is bringing one to us to conduct the experiment itself. All we need to do is watch as Apophis is stretched and compressed by powerful tidal forces.”

Ramses will utilize a variety of scientific instruments to comprehensively study Apophis, analyzing its shape, surface, orbit, rotation, and more.

The collected data will be closely examined by scientists to understand the asteroid’s composition, structure, and how to deflect potentially hazardous asteroids in the future.

Experts predict that Earth’s tidal forces could alter the asteroid’s rotation, potentially causing earthquakes and landslides. They hope that Ramses’ flyby will offer detailed observations of how Apophis is affected by the close encounter.

Additionally, NASA is redirecting its OSIRIS-REx spacecraft (now renamed OSIRIS-APEX) towards Apophis, set to arrive about a month after the 2029 flyby.

OSIRIS-REx was the first US mission to collect samples from an asteroid, returning material from Bennu to Earth in September 2023. After successfully delivering the sample, the spacecraft was renamed OSIRIS-APEX for its new mission to explore Apophis.

“Ramses will demonstrate humanity’s capability to deploy a reconnaissance mission to rendezvous with an approaching asteroid in just a few years,” said Richard Moisle, head of ESA’s Planetary Defence Division.

A decision on the full implementation of Ramses will be made at ESA’s Ministerial Council meeting in November 2025. If approved, Ramses will not only enhance knowledge of asteroid deflection but also provide valuable scientific insights into the solar system’s formation and evolution.

NASA Successfully Completes First Mission Simulating Astronaut Life on Mars

NASA is working on developing the technology to send astronauts to Mars. Early 2030s The mock journey was the first of three planned journeys to the habitat as part of NASA’s Crew Health and Performance Exploration Analog (CHAPEA) mission.

Upon emerging from the habitat, the volunteers were welcomed by a cheering crowd.

“Hello. It’s really great to be able to say hello to you all,” CHAPEA Commander Haston said with a laugh.

The mission aimed to test how the group would handle the challenges humans would encounter on Mars. The crew faced environmental stress, communication delays, and limited resources. They consumed preserved foods as well as vegetables they cultivated during their quarantine.

Brockwell, who also serves as an aeronautical engineer, structural engineer, and public works manager at CHAPEA, noted that the mission provided valuable insights on sustainability.

“I’m thankful for the opportunity to implement the concept that resources should be used at a sustainable rate and waste should be managed effectively,” he said.

The crew of the first CHAPEA mission arrived at the Johnson Space Center in Houston, Texas on July 6 after completing a one-year mission.

“Without following these principles we cannot live, dream, create, or explore for long periods of time. But if we do follow them we can achieve and sustain amazing and inspiring things, like exploring other worlds,” Brockwell added.

Mars Dune Alpha is located at NASA’s Johnson Space Center in Houston. The habitat is A sandbox full of red sand There, participants will simulate a “Mars walk.” The habitat will have private rooms, a kitchen, and two bathrooms. There will also be areas for medical, recreational, fitness, and work activities, according to NASA.
