Soyuz MS Rocket from Baikonur Cosmodrome in Kazakhstan
Rhiannon Adam
This ghostly image of Soyuz Ms Rocket in Baikonur Cosmodrome, Kazakhstan, was taken the night before it took off to the International Space Station in December 2021, and has a particularly moving resonance for the photographer. Rhiannon Adam.
About a month ago, she was said to be one of the eight-person crew members of the Dearmoon Project. It was set to become the first civilian mission to the moon, and was scheduled to be released in 2023 using a rocket developed by SpaceX, but was later cancelled.
Adam was part of a large crowd that was taken that night to see the Soyuz rocket. When the others began to leave, she strolled around to get a shot of her before being escorted by security. “Before I fired the shutter, I didn’t have a cable release so I held my breath and closed my eyes,” she says. “It was a creepy alien green light, and the flood lights mixed with the fog, so I thought it was a sight I might never see again.”
Adam had to take two frames and cross the fingers that came from the photo before being guided to the waiting bus. “Fortunately, I did. This image is a bit bittersweet for what’s symbolic to me now, but when I can separate it from my life, I still think it’s a beautiful monument to human achievement,” she says.

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.
The NASA/ESA Hubble Space Telescope produced excellent images of a small portion of the Veil Nebula, part of the remnants of a supernova called the Cygnus loop.

Cygnus loop It is a large donut-shaped nebula located approximately 2,400 light years from Earth.
Also known as the W78 and Sharpless 103, it is actually an explosive blast from a supernova explosion that occurred 10,000 to 20,000 years ago.
Its name comes from the position of the northern constellations of Cygnus and covers an area 36 times the full moon.
The visual part of the supernova remains is known as the veil nebula, also known as the caterpillar or filamentous nebula.
“This nebula is about 20 times more star remnants than the sun that exploded 10,000 to 20,000 years ago,” said Hubble astronomers.
This new image consists of observations from Hubble Wide Field Camera 3 (WFC3) Optical part of the spectrum.
“This view combines images taken with three different filters to highlight the release from hydrogen, sulfur and oxygen atoms,” the astronomer said.
“The image shows just a small part of the Veil Nebula. If we could see the entire nebula without the help of a telescope, it would be as wide as six full moons were placed side by side.”
“The image captures the Veil Nebula at just one point, but it helps researchers understand how the remnants of the supernova have evolved over the decades.”
“Combining this snapshot with Hubble observations from 1994 reveals the movement of individual knots and gas filaments over that time, improving our understanding of this stunning nebula.”
The new NASA Space Observatory is set to launch into orbit on Thursday with a crucial mission to map over 450 million galaxies.
The Spherex mission, short for the spectrophoton meter of space history, reionization epoch, and Ice Explorer history, will map the entire sky four times over two years, giving scientists the chance to study galaxy formation and uncover insights into the universe’s evolution.
“That’s going to answer the fundamental question: how did we get here?” Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA headquarters, stated in a recent news briefing.
Spherex is scheduled to be launched from the Vandenberg Space Force Base in California at 10:09 pm on Thursday.

The $488 million Spherex mission has been in development for approximately 10 years. According to NASA, it aims to map objects using 102 infrared colors and light.
Infrared technology allows scientists to see through dust and gas, observing some of the oldest stars and galaxies in the universe. By utilizing spectroscopy, scientists can analyze the composition, density, temperature, and movement of celestial objects.
The Spherex Observatory employs spectrometers to explore the sky in three dimensions and study hundreds of millions of galaxies’ properties, as stated by Jamie Bock, a lead investigator at the Spherex mission and a physics professor at the California Institute of Technology.
Bock mentioned that these observations could provide insights into galaxy formation and allow researchers to examine the origins of water and other organic materials in the Milky Way galaxy.
“When you dissect light, you can determine the galaxy’s distance, construct a three-dimensional map, and identify the water fingerprint,” Bock explained.
Unraveling the origins of water can enhance scientific understanding of life’s evolution on Earth and possibly reveal clues about vital life components elsewhere in the galaxy.
“This new capability can lead to discoveries or surprises,” Bock added.
By mapping the celestial sky, the Spherex mission addresses one of astronomy’s enduring mysteries: The Big Bang that Created the Universe approximately 13.8 billion years ago.
One theory proposed in the late 1970s and early 1980s suggests the universe experienced a staggering trillion-fold expansion in the first fraction of a second post-big bang. Known as cosmic inflation, this theory aims to explain the universe’s curved geometry, structure formation, and rapid expansion.
However, astronomers have grappled with connecting the driving force behind this cosmic inflation and why it occurred. By meticulously mapping hundreds of millions of galaxies, the Spherex mission can test theories in new ways, aiding scientists in refining the physics underlying the universe’s inflation and rapid expansion.
“What Spherex does is test specific inflation models by tracking hundreds of millions of galaxies in three dimensions,” Brock noted.
Domagal-Goldman expressed that the Spherex Mission’s exploration of galaxies, cosmic inflation, and the universe’s origins could deepen human comprehension of basic physics.
“We are fortunate to live in an era where we can uncover answers about the universe’s long narrative of human existence on this planet,” he remarked.
Musk referred to Mogensen as an “idiot” and used a light pejorative term that escalated quickly.
“SpaceX could have brought them back a few months ago.” The tweet was posted. “I presented this directly to the Biden administration, and they rejected it. The return was delayed for political reasons. Idiot.”
Mogensen, who shuttled between the space station on a SpaceX rocket and capsule, replied 13 minutes later, acknowledging Musk’s earlier praise for his work with SpaceX.
“Like me, you know that Butch and Suni are back with Crew-9, just like me, as planned since September last year.” He mentioned in another tweet about NASA’s plan to bring Willmore and Williams back to Earth alongside two current space station crews. “Even now, you haven’t sent a rescue ship to bring them back. They’ve returned to the Dragon Capsules they’ve been working on with the ISS since September last year.”
Mogensen was the commander of the Space Station from September 2023 to March 2024, continuing to be stationed at his recent orbital post.
Neither the White House nor NASA immediately responded to requests for comment.
Former Canadian astronaut Chris Hadfield, who led the space station in 2013, also reiterated his initial comment on X on February 14th.
“Suni and Butch have never been ‘stuck’ in space,” Hadfield stated. “They are well-prepared and dedicated to their missions, like all professional astronauts. Leading the Space Station Commander is Suni, and they are onboard spacecraft working diligently on behalf of NASA and all their partners. I commend their dedication.”
Spatt’s role as one of Trump’s top political advisers has raised new questions about his tendency to disseminate false and misleading information. Musk has also recently spread several misleading claims regarding fraud and spending within the US government.
Wilmore and Williams were launched on Boeing’s Starliner spacecraft in June 2024 to the International Space Station, intending to spend about a week as part of their test flight.
However, the capsule encountered several issues and was forced to prolong its stay at the space station. Ultimately, NASA decided to return the Starliner to Earth in September.

Under the Biden administration, NASA has requested SpaceX to bring Willmore and Williams back to Earth. Their return, initially set for this month, was postponed to late March. NASA cited the need to “finalize” the new SpaceX spacecraft that will transport four new crews to the space station.
This flight, called Crew-10, is scheduled to carry NASA astronauts Anne McClain and Nicole Ayers, Russian astronaut Kiril Peskov, and Japanese astronaut Onishi to the space station.
Upon their arrival, Wilmore and Williams will depart the station in another Dragon capsule, alongside NASA astronaut Nick Hague and Russian astronaut Alexander Golbunov.
Typically, incoming crews overlap with outgoing ones during handover periods, allowing astronauts to exchange information about ongoing experiments, maintenance tasks, and other protocols.
Musk also reiterated on Thursday. He suggested that the space station should be deorbited, proposing a timeline of two years instead of NASA’s plan to deorbit the facility by 2030.
“It has served its purpose. There are limited further utilities,” he stated. “Let’s aim for Mars.”
Using Gemini South Telescope, NSF's Noirlab astronomers imaged a beautiful nebula around the young open cluster NGC 2040.

Miller & M. Rodriguez, International Gemini Observatory & NSF No Arab/TA Rector, University of Alaska Anchorage & NSF No Arab/NSF No Arab/NSF No Arab, NSF No Arab.
NGC 2040 It is about 160,000 light years away from Earth, the constellation of Dorado.
This cluster, also known as the Cal 60 or ESO 56-164, resides within the large Magellan cloud, a satellite d-star galaxy of the Milky Way.
NGC 2040 is a so-called OB association, usually a stellar group containing stars between 10 and 100 stars O and B.
“O- and B-spectral types of stars live a short life of just millions of years, burning very hot before they explode like supernovae during that time,” Noirlab astronomers said in a statement.
“The energy released by these massive star explosions will be fed into the formation of NGC structures in the 2040s, while the material emitted sowing the growth of the next generation of stars.”
Most of our galaxy stars are thought to have been born in the OB Association, as well as NGC 2040.
“NGC 2040 is part of a large structure of interstellar gas known as LH 88, one of the largest active star-forming regions within the large Magellan cloud,” the astronomer said. Ta.
“Thousands of new stars will be born in the region over the millions of years to come.”
“When stars O and B end their supernovae life, they enrich the clusters with elements like carbon, oxygen and iron,” they said.
“Along with the rich hydrogen in the cluster, these elements provide the components necessary for the formation of new stars, planets, and perhaps life.”
“The bright stars seen in the image are widely separated, but their movements through space are similar, indicating that they have a common origin.”
“The layered ambiguous structure of LH 88 is the remains of an already dead star.”
“The delicate leaves of the rose were formed by both the shock waves of the supernova and the stellar winds of the stars of O and B.”
The 11 -year survey of particles near our sun and anti -particles has emerged the history of our solar system and causes a new mystery about the particles itself.
“It seems like I stepped into a dark room and saw a lot of new things.” Samuel Tin At Massachusetts Institute of Technology.
Energy particles are filled in the space, which is moved by burst called cosmic rays. When the cosmic ray enters the Alpha Magnetic Difference (AMS) detector of the International Space Station (ISS), the magnetic field separates particles based on the charge, and the detector measures mass and energy. This separation is important because it helps to identify the differences between particles and their anti -particles.
AMS collaboration, and his colleagues, analyzed more than 11 years of AMS data, and found that we didn’t know much about the particle behavior as we thought. For example, this survey reveals how the number of particles tends to be over time and how different types of particles interact with each other. Ting says that there are more than 600 theoretical models that can explain each of these trends, but there is nothing to explain both surveys at the same time.
And the results of the survey may be important for more than a single particle. Researchers say that the changing characteristics may be useful as a record of the history of the solar system, so they are shooting cosmic rays with different detectors for more than a century. Jamie Lankin At Princeton University. However, she says that we have never understood how the solar cycle affects the light rays.
This is because 11 years is the length of one solar cycle, so collecting data during that period captures all repeated fluctuations in the sun magnetic field, and the behavior of cosmic rays changes. She says that such a detailed investigation can be a key to solving a method of using cosmic rays in “solar system archeology”.
However, he says that the cosmic ray itself is still mysterious. Gavin Lowell At Adelaide University in Australia. “The measured value of the particle AMS is essentially from outside the solar system,” he says. Detailed amounts of new analysis, including how different particle nuclei on the cosmic ray acts, may help researchers focus on more decisive theories of cosmic rays.
There is also a question of other unexplored universe. “It’s a big mystery for me that AMS can observe antiproton because we don’t see antimatters in our world.” Ian Low At Northwestern University, Illinois. He says that the origin of these anti -particles is connected to a mysterious dark substance, and otherwise it may be better than our current universe.
Ting and his colleagues are currently working on upgrading the AMS detector, can detect more particles, and are adjusted as astronauts who support the installation.
The melodious high-pitched sound of birdsong is not something typically associated with the vastness of space, usually serving as a delightful indication of the arrival of spring. However, to the surprise of many, scientists at China’s Beijing Aviation University have recently stumbled upon a similar occurrence over 100,000 kilometers away from Earth.
Through the analysis of data collected from NASA’s Magnetospheric Multiscale (MMS) satellite, researchers have pinpointed a phenomenon referred to as “chorus waves,” which consist of bursts of electromagnetic radiation traveling along Earth’s magnetic field lines.
If one were to venture into space, this sound would remain unheard due to the absence of air for sound waves to propagate. Interestingly, upon conversion into an audio signal for examination, this “chirp” is actually the auditory representation of these waves.
So, what exactly causes these electromagnetic chirps? Contrary to expectations, it is not a celestial songbird. In reality, chorus waveforms are relatively common. However, the peculiarity lies in their location, as highlighted by their distance from Earth.
The energy transfer induced by chorus waves prompts electron acceleration to speeds nearing that of light, crucial for the formation of Earth’s radiation belts which shield against the sun’s energetic particles.
While these accelerated particles contribute to the magnificent aurora borealis, they are also dubbed “killer electrons” due to the hazards they pose to satellites, astronauts, and crucial communication systems.
Typically, these waves are found around 51,000 km (32,000 miles) away, in a region influenced by the “magnetic dipole effect,” defining the Earth’s magnetic field with north and south poles.
However, a 2016 study published in nature unveiled that for the first time, these chorus waves have been observed at distances up to 165,000 km (103,000 miles) from Earth, in regions where the magnetic field is distorted and dipole effects are absent.
Furthermore, these waves exhibit similar properties to those closer to Earth, lasting around 0.1 seconds with frequencies reaching nearly 100Hz (akin to the noise of a revving car engine).

Why is this discovery significant? It indicates that Earth’s environmental conditions are not prerequisites for wave generation as previously assumed by scientists.
“Though this finding does not refute existing theories… it certainly prompts a deeper investigation,” remarked Professor Richard Horne, head of space weather at the British Antarctic Survey, not involved in the study.
“The unexpected presence of chorus waves in this region calls for further exploration in areas where the Earth’s magnetic field displays substantial deviations from the dipole.”
Chorus waves play a vital role in shielding Earth from solar storms, yet they also pose potential dangers. Enhanced understanding of these waves can lead to better protective measures.
Horne expressed that this breakthrough “will significantly enhance our comprehension of these waves and refine our capacity to forecast them.”

They say you shouldn’t start a story by waking up, but when you’ve been in a deep sleep for 30 years, you don’t know where else to start.
It may begin with awakening and end with awakening.
I’ve heard that hard sleep is a technical term. It’s hard because you’re shut down, dry, and frozen for your journey from star to star. They make it into art – it takes 11 minutes like clockwork. The whole ship is full of villains and they are dry to the point of being able to do anything. . . Well, I was going to say that you can survive indefinitely, but of course that’s not the case. you don’t survive. You die, but you’re flash-frozen in a very specific way, allowing you to more or less pick up where you left off on the other side. After all, a detour about it would kill any body that is not withered – a permanent and irreparable kind of killing.
They are full of things that re-expand you to more or less previous dimensions – you will notice that there are many more or less In this process. It’s an exact science, but it doesn’t bother you exactly. The thought process does not pick up where it left off. Short-term memory is not stored. The mental path these days doesn’t work. Therefore, start by waking up. Because until you can establish a connection with an old memory, that’s all you have at that moment. I know who I am, but I don’t know where I am or how I got there. It sounds scary, but let me tell you, when you wake up, you’ll find yourself in a real hell. The roar of massive structural damage echoes as ships are destroyed around you. The jostling impact when the little translucent plastic bubble you’re riding on loosens and starts rolling. A cacophony of vibrations that travels through the curved surface to you. The death knell of the vessel that carried you here, carried you out into the void, and is now fragmenting. At that time, there is a world below that is not in your head and that you know nothing about. And above you there is only a cosmic murder field. The fact that there is a bottom and a top indicates that the earth has already won a certain battle for your soul and you are falling. The oldest fear of apes is the fear of involuntarily clenching a baby’s rubbery hand. It is a fall from grace that neither mankind nor apes ever imagined.
You can also see other people around you, through the celluloid walls of the prison. Because there can be no hell without fellow sinners to suffer. Each in its own bubble, torn from the collapsing ship. His face was contorted with fear, he screamed and banged on the wall, his eyes were like wells and his mouth was like the gate of a tomb. Please excuse the excessive explanation. I’m an ecologist, not a poet, but mere biology isn’t enough to appreciate the horrific spectacle of 500 humans being brought back to life at once and no one understanding why. you For reasons unknown, the ship falls apart in the cracks, and the world below is the hungry mouth of a gravity well. oh my god! When I remember that, my stomach hurts. And above all, in the midst of that confusion, I remember that I’m an ecologist. A universe without even an ecosystem. Has any self-knowledge ever been so useless?
Some of us have not yet woken up. I see at least two bubbles flying past me. Inside, the crew was left as desiccated corpses, and the systems malfunctioned. “Acceptable waste” is a technical term, but it’s also a concept you don’t want to suddenly remember. Because there will always be people at the end who will not wake up. They say this is an inevitable violation of entropy on a very long journey. Maybe so. Or maybe those who don’t wake up are the worst troublemakers. It’s hard to tell who it is when the skin clings to the skull without any familiar flesh intervening, but I notice my old colleague Markein El whirling past. I think I saw it. She was transported all the way from Earth here at minimal cost with a boiled-down process, but it might have been better to throw her in an incinerator to achieve the same effect.
Another piece of knowledge comes from remembering minimal costs. Another couple of my neurons resume a severed acquaintance, bringing with it a related but unwelcome understanding. This is intentional. Not the traumatic wreck of the Hesperus. It’s a feature, not a bug. Sending people into space used to be expensive, and it’s still expensive for anyone interested in space. It is recommended to provide practical medical care and life support, waking up from time to time to check on your very sensitive physical and mental health to ensure you stay alive while on the move. And, noticeably, it is recommended to arrange means of bringing them. return After completing the mission, return home. Large, expensive ships capable of complex maneuvers such as refueling, decelerating, accelerating, and turning.
But if you just want to send felons to a labor camp on a remote planet, it’s literally cheaper and easier than having a machine do the same job, so you don’t have to worry about them coming back. Because they don’t. It’s a life sentence, a one-way trip. Even as my head falls into the temptation of Imno 27g along with the rest of me, further unwelcome revelations fall upon my head.
I should have smashed my newly revived fist into the inside of the bubble, but it was falling from the collapsing ship and swirling around, the world below growing larger and larger. The void became a yellow-blue sky. Do you have yellow and blue? This is not the earth, but this is the sky of Immuno. Blue represents the oxygen that the planet’s biosphere pumps into the atmosphere as a byproduct of metabolic pathways, just like on Earth. Yellow is a diffuse cloud of aerial plankton. Alternatively, it is actually yellow-black due to its dark photosynthetic surface. Blue, yellow, and black should not be colors, and above all, should not be the color of the sky.
we fall At some point the chute will open. It is a film-like transparent plastic that is biodegradable the moment it comes into contact with the atmosphere. Like a ship, it is designed to last for the minimum amount of time possible to accomplish its mission. The ship is just a nameless piece of plastic junk printed as a single piece in Earth’s orbit, with a single engine and a pod to hold us all like peas. Probably an egg case. It is designed to carry a cargo of corpses across space to one of what the Mandate’s expansion division calls one of its current “active planets.” It carries us up to Immuno 27g and then breaks us apart in the upper atmosphere. Single-shot medical units reanimate their cargo from the dead, crushing lost souls as they scream and tumble to our doom. Some people don’t wake up, and even if they wake up, others don’t survive the descent. Destruction is certainly something we all face, but for some it lasts less than for others. Every time the chute unfolds, the bones tremble, and while I see others similarly torn from the teeth of the ground, I also watch a handful of bones fall as the chute fails. They’re still screaming because they remember just knowing that they’re going to die all over again.
You won’t die by not waking up, and you won’t die by falling off the edge of the atmosphere. I am not recorded in the ledger as acceptable waste. They will have to calculate very carefully the exact level of expense required and the exact proportion of delivery failures, or deaths, that this will entail. After all, who would want to spend a penny more than necessary to send a death row inmate to a concentration camp in a faraway world? People who rebelled against the system and now have to pay their dues for the rest of their lives. Some people are like me. You’ll hear the numbers later, but acceptable waste is 20 percent. If that sounds like an absurd loss of investment, you don’t know the history of people transporting others from place to place against their will.
They loaded the pods with maneuver jets. small plastic thing. One shot. It seems like it will take a lot of time to fall! – I see them firing. Each injects a bottle of gas, destroying itself in the process. If you can land where you need to land, that’s fine. Even if I end up far away from the work camp, they aren’t going to waste the labor time it takes to retrieve me. I would die trapped in a bubble or trapped outside a bubble because Immuno 27g is full of things that will kill you. Especially when you’re alone and only half your brain is with you. There was nothing in my head that would help me survive in this other world.
But that doesn’t happen to me either. I land at the same spot with everyone else who is not subject to waste regulations and they are waiting for us there. The camp commander sent a large crowd in case we managed to form a revolutionary subcommittee during our descent. When I saw riot control armor and guns – the “minimally lethal” security equipment I (now) remembered from Earth, that only killed an acceptable percentage of the time – I I remembered it there. had I was on a revolutionary subcommittee. Of course not on the ship. Because we were all flash-frozen corpses. And it wasn’t on the way down. Because we were too busy shouting. But back on Earth, before they invade our networks, track our contacts, and arrest everyone we know for betraying our friends and family, I actually I got this because it was part of the problem. When I returned to Earth, I was stubbornly proud of that fact. In the cramped orbital quarters of a prison attached to a spaceport, yes, I knew I would be deported to a concentration camp, but even a junior scholar like me could at least do what I could. I’ve been trying to do that. .
Now, after plummeting to this fate and then watching the Death Slash Welcome Committee, I regret everything. If a political official magically appeared and offered me a pardon if I signed a confession, I would reach for a pen. Quite unlike this song, I regret every single choice in my life that led me to this point. This is a moment of weakness.
Bubbles deflate around me. I struggled to fight it off for a minute to avoid choking on the sticky plastic before it cut me off. They have special tools, such as heated knives, to do this. I got a shallow glowing cut along my thigh, which attests to their general carelessness in handling it. One more person will be wasted when the last one is released and by then it will be too late. Everything is within tolerance, you understand. That’s it. I’m depressed. Look up at the foreign sky.

IThis was one of the most impressive technology events of the year. On October 13, Starship, the world’s largest and most powerful rocket, blasted into space from a launch pad in Texas. The main booster reached an altitude of more than 65 km and then began returning to Earth at speeds exceeding the speed of sound.
A crash was averted when the rocket, developed by Elon Musk’s SpaceX company, reignited its engines, slowed, and came to a grinding halt above the tower from which it had launched just seven minutes earlier. The scissor’s claws grabbed the massive launcher, gripping it tightly, ready to refurbish and fire again.
“Today is textbook day in engineering history,” said SpaceX engineer Kate Tice.
prestigious research journal science “This feat heralds a new era of affordable heavy-lift rockets that can reduce the cost of doing science in space,” the company said last month in awarding Starship’s October flight. Announced. This year’s breakthroughs.

Musk’s company has already cut the cost of putting cargo into Earth orbit by one-tenth, the magazine said. Further reductions of similar magnitude can be expected when Starship, the most powerful launcher ever built and designed to be completely and rapidly reusable, becomes fully operational later this year, it added.
This view is shared by many space engineers, who believe Starship is poised to take a major leap forward with a schedule of launches every two to three weeks. SpaceX engineers have learned how to salvage and reuse the main booster stage and plan to do the same with the upper stage this year.
With a total of 25 flights planned over the next year, this is an incredibly ambitious program. “You don’t have to be a rocket scientist to understand that their research schedule is unprecedented,” astrophysicist Ehud Behar, a Technion professor at the Israel Institute of Technology, told the website Space.com.
For scientists, the benefits of Starship are clear. The cost of missions on reusable launch vehicles could drop significantly from current levels, making it possible to conduct research in space that was previously unaffordable. This point is important, he said. science In an editorial about Starship’s achievements, he said:
Until now, access to space was too precious to risk failure, the magazine said, and NASA missions tested components over and over again, driving up costs. “But regular Starship flights will give scientists more opportunities, allowing them to build instruments using inexpensive off-the-shelf parts and launch them more frequently.”
In addition to single vehicles, fleets of robotic probes could be sent to Mars, and fleets of mirror segments could be flown in formation to create giant self-assembling telescopes in space. While such a vision is exciting, there are downsides to Musk’s rocket success.

First, Starship could destroy NASA’s own rocket system, the troubled and extremely expensive Space Launch System (SLS), which the agency has been planning for decades. Unlike the reusable Starship, its rocket is expendable, while launching SLS will cost billions of dollars compared to the $10 million goal Musk has planned for the system. It is expected that it will cost. Many scientists predict that Starship will eliminate the need for SLS within a few years.
Another major problem for many scientists involved with SpaceX is that they have difficulty accepting Musk’s right-wing politics and close ties to Donald Trump. He is a vocal critic of U.S. immigration policy, has disdain for many Democratic politicians, and was recently given permission by President Trump to cut $500 billion from the U.S. federal budget.
In any case, Musk’s hopes for Starship have less to do with scientific aspirations and much more to do with his desire to eventually begin colonizing Mars using giant rockets. Last September, he promised that SpaceX would launch its first unmanned Starship mission to Mars in two years. If successful, manned flights would follow within four years. Ultimately, Musk said he envisions a potential colony of up to 1 million people on Mars within 30 years.
The controversial billionaire’s plans brought him a lot of attention and ridicule. Indeed, we have sent humans on a 140-meter-mile journey to the Red Planet, survived blasts of dangerous cosmic radiation, and figured out how to grow food in an atmosphere where water is scarce and the average pressure is less than 1% that of Earth’s oceans. Finding the level – challenging to say the least.

Leaving Earth for Mars is “like leaving a cluttered room to live in a toxic waste dump,” Kelly and Zach Weinersmith write in their book. Cities on Mars: Can and should we settle in space? And have we really thought about this?, which one Winner of the 2024 Royal Society Trivedi Scientific Book Award.
This is a view echoed by Astronomer Royal’s Martin Rees, who has also attacked Musk’s Mars proposal. “We should never expect mass immigration from Earth,” he says. “It’s a dangerous delusion to think that space can escape Earth’s problems. We have to solve them here. Dealing with climate change may seem daunting, but Mars Nowhere in our solar system are environments as harsh as Antarctica, the ocean floor, or the top of Mount Everest.
“For ordinary risk-averse people, ‘Planet B’ does not exist.”
From this perspective, Starships may have some impact on space science, but they are unlikely to change the course of human history.
The coming year is expected to be filled with ambitious space missions.
Multiple robotic landers are expected to be launched to the moon in the coming weeks or months.
China and India also each hope to achieve new milestones in space later this year.
From robotic expeditions to the moon to new observatories in space and rendezvous with asteroids, 2025 promises to be full of ambitious space exploration.
NASA and U.S. commercial space companies aren’t the only ones busy. Launch plans planned for this year include potential milestones in China, Japan and India.
Here are some of the biggest upcoming space missions.
Moon fever continues
In 2025, the moon will once again be in the spotlight.
Later this month, SpaceX rockets are scheduled to launch two new missions to the moon. One, a lander called Blue Ghost developed by Texas-based company Firefly Aerospace, is intended to spend about two weeks collecting scientific data on the moon. The second is a privately built Japanese lunar lander with an attached small rover.
The Blue Ghost attempts to land on a region of the moon known as the Moon.Mare Crisium is thought to be the site of an ancient asteroid impact.
The mission is part of NASA’s Commercial Lunar Payload Services Initiative. The space agency has signed contracts with three private companies, including Firefly Aerospace, to transport scientific experiments, technology and other cargo to the moon’s surface. The effort is part of NASA’s larger Artemis mission, which aims to eventually return humans to the moon. The Blue Ghost mission will carry out 10 NASA science and technology experiments.
Riding into orbit on the same rocket booster will be a resilient lander developed by a Japanese company called ispace and the Tenacious “micro rover.” It aims to take a longer route to the moon, consuming less energy than the Blue Ghost, and land on the lunar surface approximately four to five months after launch.
The touchdown target is located in the far north of the moon, in an area called Mare Frigoris.
iSpace’s bid to become the first private company to land a spacecraft on the moon ended in disappointment last year. The company’s lander, Hakuto, accelerated unexpectedly during its descent and crashed onto the lunar surface.
A third lunar launch by the company, which was the first to land a privately built ship on the moon, could also take place this month.
Texas-based Intuitive Machines also won a contract under NASA’s Commercial Lunar Payload Services program. Last year, the company’s lander became the first American vehicle to land on the moon in more than 50 years. The company aims to send its next-generation lander to the moon’s south pole on another SpaceX rocket in the coming weeks.
The mission will include a drill to extract lunar soil and a robot that will hop into nearby craters to take images and perform scientific experiments.
Exploring the origin of the universe
NASA aims to launch the SPHEREx mission, a space observatory designed to map the entire sky in optical and near-infrared light, in late February.

The spacecraft will observe more than 100 million stars in the Milky Way and collect data on more than 450 million other galaxies.
As part of its planned two-year mission, the observatory will also search for signs of life as we know it, such as water and organic molecules, in the Milky Way. Experts hope the expedition will provide insight into how galaxies form and how the universe came into being.
Two NASA astronauts finally return home
Two NASA astronauts stranded on the International Space Station since a problem aboard their Boeing spacecraft in June are finally scheduled to return home in March.

Astronauts Suni Williams and Butch Wilmore were launched to the ISS on the first manned flight of Boeing’s Starliner spacecraft. The original plan was for the two to spend about a week on the space station, then return to Earth on the Starliner. However, the capsule encountered fuel leaks and thruster problems, so NASA opted to leave Williams and Wilmore in orbit and return the spacecraft unmanned.
They will have spent more than nine months in space before returning to Earth in a SpaceX capsule with two other space station crew members.
India’s spaceflight ambitions
India is poised to make major strides in its human spaceflight program this year.
Indian Space Research Organization (ISRO) astronaut Shubhansh Shukla will fly to the International Space Station on a commercial mission run by Texas-based startup Axiom Space.
The launch, expected by spring at the earliest, will include government-backed crew members from Poland and Hungary. The crew will spend up to 14 days on the ISS.
Meanwhile, India is also working on developing its own manned spacecraft, aiming to launch its first one in 2026.
A new private space station?
California-based startup Vast plans to launch its first commercial space station into orbit this year. The civilian outpost, called Haven-1, is scheduled to launch by August on a SpaceX rocket.
Haven-1 is designed to accommodate four astronauts on missions of up to 30 days. The space station will initially function as an independent outpost, but Vasto plans to eventually connect it to a larger module in development.
In partnership with SpaceX, Vast intends to someday launch a crewed mission to the Haven-1 outpost, but the company has not yet announced a target date for that launch.
China encounters an asteroid
China’s space exploration shows no signs of slowing down even in 2025.
This spring, the country plans to launch a mission to collect asteroid samples, the first such expedition.
The plan calls for a spacecraft called Tenbun-2 to rendezvous with a near-Earth asteroid called Kamoorewa, which some scientists have suggested. maybe part of the moon It was ejected during an ancient collision.
The mission aims to collect debris from the asteroid, release a capsule containing samples, and return to Earth in 2026. After that, the Tenbun-2 probe is expected to orbit around the Earth and fly using the Earth’s gravity as a slingshot. Heading toward the comet known as 311P/Panstars. The spacecraft is expected to arrive at the comet in the mid-2030s.
If China’s asteroid sampling mission is successful, it would be a major accomplishment for the country’s space agency. This would be an achievement that follows several recent milestones. China has already become the first company to collect and return samples from the far side of the moon, landed a rover on Mars and completed construction of its own Tiangong space station.
NASA announced on Tuesday that two astronauts have been stranded on the International Space Station since a problem with their Boeing spacecraft in June. Due to delays, they will have to remain there even longer.
The next astronaut launch to the ISS, originally scheduled for February, has been postponed to late March. This is to allow the new SpaceX spacecraft used for the mission more time to complete processing.
The four crew members currently on board the station must wait for the next crew member to arrive before departing in another SpaceX Dragon capsule. Among them are NASA astronauts Suni Williams and Butch Wilmore, who are set to embark on the first test flight of Boeing’s Starliner spacecraft.
Originally planned to spend about a week on the space station, Williams and Wilmore have now been living and working in orbit for over nine months, including additional time due to the recent delay.
Typically, new crew members overlap with departing crew members for a short period on the ISS, known as the handover period. During this time, astronauts exchange information about ongoing experiments, maintenance projects, and other protocols.
When Williams and Wilmore finally depart, NASA astronaut Nick Haig and Russian cosmonaut Alexander Gorbunov will also return home with them.

According to officials, the new Dragon capsule scheduled for launch in late March should arrive at NASA’s processing facility in Florida in early January. Steve Stich, NASA’s commercial crew program manager, emphasized the meticulous attention to detail required in manufacturing, assembling, testing, and integrating a new spacecraft.
The capsule, known as Crew 10, will be launched by NASA astronauts Anne McClain and Nicole Ayers, Russian cosmonaut Kirill Peskov, and Japanese cosmonaut Takuya Onishi. Until then, the quartet will continue training for the mission at NASA’s Johnson Space Center in Houston.
The Hubble team has released a striking new image of the center of NGC 5643, a spectacularly designed spiral galaxy in the constellation Lupus.
This Hubble image shows NGC 5643, the Grand Design Spiral in the constellation Lupus, about 55 million light-years away. Image credits: NASA / ESA / Hubble / A. Riess / D. Thilker / D. De Martin, ESA & Hubble / M. Zamani, ESA & Hubble.
NGC5643 It is located approximately 55 million light years away in the constellation Lupus.
The planet, also known as ESO 272-16 and LEDA 51969, was discovered by James Dunlop on May 10, 1826.
NGC 5643 is classified as a Grand Design Spiral due to its prominent and graceful spiral arm.
It is approximately 100,000 light-years in diameter and contains an active galactic nucleus of type Seyfert 2.
“NGC 5643 is what is known as a Grand Design Spiral, which refers to how the galaxy's two large, sinuous spiral arms are clearly visible,” Hubble astronomers said in a statement.
“The spiral arms are defined by bright blue stars, lacy reddish-brown dust clouds, and pink star-forming regions.”
“As fascinating as the galaxy is at visible wavelengths, some of NGC 5643's most interesting features are invisible to the human eye.”
New images of NGC 5643 consist of observations from. Hubble's Wide Field Camera 3 Found in the ultraviolet, infrared, and optical portions of the spectrum.
Nine filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.
“The ultraviolet images, X-ray images, and spectra of NGC 5643 show that this galaxy has an active galactic nucleus, a particularly bright galactic nucleus driven by a feast of supermassive black holes,” the astronomers said. said.
“When a supermassive black hole takes in gas from its surroundings, it collects in a disk and heats it up to hundreds of thousands of degrees.”
“Superheated gases glow brightly across the electromagnetic spectrum, but especially at X-ray wavelengths.”
“However, NGC 5643's active galactic nucleus is not the brightest X-ray source in the galaxy,” the researchers added.
“Researchers using ESA's XMM Newton discovered an even brighter X-ray emitting object called NGC 5643 X-1 on the outskirts of the galaxy.”
“What source of X-rays is more powerful than a supermassive black hole? Surprisingly, the answer appears to be a much smaller black hole.”
“The exact identity of NGC 5643 X-1 is not yet known, but evidence points to it being a black hole with about 30 times the mass of the Sun.”
“A black hole trapped in an orbital dance with a companion star captures gas from the companion star, creating a superheated disk above the center of the galaxy.”
Hubble astronomers previously released images of NGC 5643 in 2020.
Astronomers using the NASA/ESA Hubble Space Telescope have provided an unparalleled snapshot of intermediate spiral galaxy NGC 1637.
This Hubble image shows NGC 1637, an intermediate spiral galaxy located about 38 million light-years away in the constellation Eridanus. Image credit: NASA / ESA / Hubble / D. Tilker.
NGC1637 It is located in the constellation Eridanus, about 38 million light years from Earth.
This galaxy, also known as LEDA 15821 or UGCA 93, is located around this galaxy. 30,000 light years Across.
it was discovered It was discovered on February 1, 1786 by German-British astronomer William Herschel.
At first glance it looks like NGC1637 will be displayed Despite being a fairly symmetrical galaxy, it has some interesting features that have led astronomers to classify it as a biased spiral galaxy.
“The new images of NGC 1637 come from an observational program dedicated to studying star formation in nearby galaxies,” Hubble astronomers said.
“Stars form in cold, dusty gas clouds that collapse under their own gravity.”
“As young stars grow, they heat the nursery with starlight, wind, and strong outflow.”
“Together, these factors play a role in controlling the rate of star formation in future generations.”
“Evidence of star formation is scattered around NGC 1637, if you know where to look.”
“The spiral arms of the galaxy are dotted with what look like pink clouds, many with bright blue stars.”
“The pinkish color comes from hydrogen atoms excited by ultraviolet radiation from young, massive stars.”
“This contrasts with the warm yellow glow at the galactic center, where older, redder stars are densely clustered.”
“The stars that sparkle their birthplaces are relatively short-lived, and many of these stars explode as supernovae just a few million years after their birth.”
In 1999, Lick Observatory's supernova search discovered a type II supernova in NGC 1637.
named SN 1999emThis supernova was hailed as the brightest supernova observed that year.
It has been closely tracked by astronomers and has been shown to have dimmed relatively slowly over the years.
“When a massive star annihilates as a supernova, its explosion outstrips its entire home galaxy for a short period of time,” the astronomers said.
“Supernovae mark the end of a star's life, but by compressing nearby gas clouds, they can also jump-start the formation of new stars, starting a star's life anew.”
Astronauts aboard the International Space Station are ready to break Thanksgiving bread in orbit.
NASA astronaut Suni Williams said she and her fellow crew members will be taking the day off to celebrate.
“I’m packing a lot of Thanksgiving-y food,” Williams said Wednesday in an interview with NBC News. “Smoked turkey, cranberries, apple cobbler, green beans and mushrooms, and mashed potatoes.”
She added that she plans to attend the Macy’s Thanksgiving Day Parade before dining with American and Russian colleagues.
Williams has been living and working on the International Space Station for almost six months. She and fellow NASA astronaut Butch Wilmore arrived at the orbiting outpost in early June as test pilots for the first manned flight of Boeing’s Starliner space capsule.
The two were scheduled to stay on the ISS for only about a week, then return to Earth on the Starliner. However, problems with the spacecraft kept them in orbit for months longer than expected. Wilmore and Williams are scheduled to return home in February in a SpaceX Crew Dragon capsule.
Starliner’s difficult mission was a dramatic, months-long story for NASA and Boeing. But Williams said she doesn’t feel like she’s “stranded” in space.
“Our control team and management always had the option of us returning home,” she said. “Yes, we came here on the Starliner. We’re coming back on the Dragon, but there was always a plan for how we were going to get home.”
In the last few weeks, NASA dodged the rumors Williams reportedly suffered from health problems while in space. Although some news articles suggested that the astronauts had lost significant weight, the agency’s medical director said on Nov. 14 that the health of Williams and others on board the space station was He said the condition was good.
Williams told NBC News that he is enjoying his time in orbit and is in good spirits.
“We feel good, we exercise and we eat properly,” she said. “We’re having a lot of fun here, too. So people are worried about us. Really, don’t worry about us.”

Despite problems that occurred during Starliner’s voyage (mainly thruster and helium leaks), the capsule returned to Earth without a crew on September 7th. Williams said he wished he had been able to see Starliner’s mission to completion.
She added that Boeing and NASA would not hesitate to send Starliner into space again if they ironed out the problems that arose during the test flight.
“It might not be tomorrow because we need to incorporate some of the lessons we learned,” she said. “But once we knew we were on the right path, we fixed some of the issues we had — absolutely.”
Astronomers using the NASA/ESA Hubble Space Telescope have taken surprising new photos of spiral galaxy NGC 2090.
This Hubble image shows NGC 2090, a spiral galaxy located south of the constellation Columba, about 40 million light-years away. Color images were created from separate exposures taken in the ultraviolet, visible, and near-infrared regions of the spectrum using Hubble's Wide Field Camera 3 (WFC3). This is based on data obtained through six filters. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / D. Tilker.
NGC2090 It is a spiral galaxy located south of the constellation Columba.
Also known as ESO 363-23, IRAS 05452-3416, LEDA 17819. discovered It was announced by Scottish astronomer James Dunlop on October 29, 1826.
“NGC 2090 is notable as part of a group of galaxies being studied. Hubble's Extragalactic Distance Scale Key Project“This study aimed to determine a new, state-of-the-art value for the Hubble constant, one of the main scientific goals of the then-new telescope,” Hubble astronomers said in a statement.
“NGC 2090's contribution was to calibrate the Tully-Fisher (TF) distance method by observing Cepheid variable stars in the galaxy.”
“Cepheid-based measurements from a 1998 study estimated the distance of NGC 2090 to be 37 million light-years.”
“Latest measurements in 2020 using the TF method place NGC 2090 slightly further away, at 40 million light-years.”
Before and after that project, NGC 2090 has been well studied as a very prominent nearby example of star formation.
It has been described as a cotton-like spiral, meaning a spiral galaxy with a speckled, dusty disk and flaky or no visible arms.
“This Hubble image gives a good indication of why NGC 2090 received such a description, with its spiral arms looking like lanes of light winding through the dust,” the astronomers said. said.
“NGC 2090 remains an active galaxy, with clusters of star formation in various stages of evolution spread throughout the disk.”
“Investigating star formation and the movement of matter within galaxies was the motivation for these Hubble observations taken in October of this year.”
“Likewise, Hubble's partner in space astronomy, NASA/ESA/CSA's James Webb Space Telescope, also scouted this galaxy to add infrared data to the picture of galaxy evolution.”
There's a lot to keep in mind when working in space
NASA (from Getty Images)
Astronauts aboard the International Space Station (ISS) have shown declines in memory, attention, and processing speed after six months, raising concerns about the impact of cognitive impairment on future space missions to Mars.
The extreme environment of space, including reduced gravity, harsh radiation, and lack of regular sunrises and sunsets, can have dramatic effects on astronauts' health, from muscle loss to increased risk of heart disease. There is a gender. However, the cognitive effects of long-term space travel are less well documented.
now, Sheena Dev Researchers from NASA's Johnson Space Center in Houston, Texas, examined the cognitive abilities of 25 astronauts while on the ISS.
The team conducted 10 tests on the astronauts, some on Earth once before and after the mission, and others on the ISS early and late in the mission. These tests measure specific cognitive abilities, such as finding patterns on a grid to test abstract reasoning, or choosing when to stop an inflated balloon before it bursts to test risk-taking. I did.
The researchers found that on the ISS, astronauts took longer to complete tests measuring processing speed, working memory, and attention than on Earth, but the accuracy was the same. Although there were no overall cognitive impairments or lasting effects on the astronauts' abilities, some measures, such as processing speed, took longer to return to normal after returning to Earth.
Having clear data on the cognitive effects of space travel is critical for future human spaceflight. Elisa Raffaella Ferre But before we know the full story, it's important to collect more data both on Earth and in space.
“Mission to Mars is not only long in terms of time, but also in terms of autonomy,” Ferre says. “Human performance is key as people on the ground will have a completely different interaction with ground control due to distance and communication delays and will need to be fully autonomous in making decisions. You wouldn't want an astronaut on Mars who has slow reaction times in terms of attention, memory, and processing speed. ”
Given the unusual environment of space, it's not surprising that there was a certain decline in cognitive performance, he said. Joe Bower at the University of East Anglia, Norwich, UK. “It's not necessarily a huge cause for alarm, but it's useful to know, especially to know your limits when you're in such an extreme environment,” she says.
That awareness could be especially helpful for astronauts on long-duration missions, Bower added. “It’s not just about how well you do on a test, it’s also about how you perceive your abilities,” she says. “For example, when you're sleep deprived, your performance often suffers, but you don't even realize it's happening.”
IThis was one of history’s monumental moments, but if John Glenn had not stopped at a supermarket on his way aboard Friendship 7 to pick up a Contax camera and 35mm film, the visual record may not have existed. A photograph taken by an American astronaut through the window of a capsule while in Earth orbit on February 20, 1962, provided unprecedented evidence of Project Mercury’s first orbital mission. The Soviet Union may have beaten the Americans in the race to human spaceflight, but the Americans were also taking the first color photographs of the galaxy.
German gallerist Daniel Blau points out that these photos are also “the most expensive photographs ever taken.” Billions of dollars were spent to obtain them. Blau has an original print of Glenn’s first photograph taken in space. Photos from Paris this yearalong with NASA’s cache of rare photographic prints, many of which have never been publicly displayed before, most of them by unknown scientists and astronauts.
“At that time, NASA didn’t provide cameras to astronauts,” Blau says. “In a way, this was Glenn’s private photograph.” Despite their scientific motivations, Glenn’s images convey the inescapable mystery of the universe. A warm, glowing ball of light spreads out from the center of the frame. Luminescent flashes blaze into the deep darkness of the void, dancing like the “fireflies” described by Glenn. It must have been terrifying to watch. In fact, the spark turned out to be condensation.
Traveling at 28,000 km/h, humans managed to reach space, but they had not yet designed a photographic machine powerful enough to keep up with the journey. Lacking much visual information or detail, Glenn’s photographs probably reveal less about the universe and have become totems of human ambition. Glenn later added a personal caption, warning, “I guarantee you a photo will never be able to recreate the brilliance of a real scene.”
Blau began carrying vintage NASA prints in the 1990s. “The Space Race and the Cold War were the defining forces of the second half of the 20th century. Of course, my generation remembers all the important moments.” Some of the photos were published at the time, but original prints It is difficult to obtain. “These scientists and the people who worked on the missions passed down their personal archives to their children, and now their grandchildren, so there is still a lot of material on the market. It was natural for me to start searching and working with these photographs.”
At Paris Photo, a crowd gathered around a series of six silver gelatin photographs from 1948 overlooking the Rio Grande from a V-2 rocket at 73,000 feet. Also on display were humanity’s first close-up photo of Mars, taken in 1965, and the first panoramic photo of Earth seen from the moon. The latter was not photographed by humans, but was sent by radio signal from an unmanned mission in August 1966. They were then stitched together pixel by pixel into a single image at NASA’s Jet Propulsion Laboratory.
By 1979, the interstellar probe Voyager was able to take better pictures of the planet, and its images of Jupiter and its four moons suspended like marble in an onyx atmosphere were particularly startling.
The impressive large-scale mosaic of Mercury’s pockmarked surface, created in 1974, is “the only mosaic of this size I’ve ever seen,” Blau says. “It was probably produced for a NASA presentation, similar to Voyager’s photo of Mars.” This photo only shows part of the solar system’s smallest planet, but it doesn’t fit our understanding and You get another glimpse of what lies beyond your control.
By the late ’70s, photography had taken on a more central role in missions and the advancement of space science. “NASA was and still is dependent on public funding, but Glenn’s color photographs taken in Earth orbit showed that the best and most positive way for NASA to demonstrate its accomplishments was through photography.” It became clear that there was one thing,” Blau said. “Of course, the scientific side of things is the driving force, but photography tells a first-hand story.”
Blau’s footage was released the day after the US presidential election. He said he wanted to remind visitors of the “positive common efforts of many countries.” They are certainly humble. “Perhaps no photograph embodies more than this photograph the combination of mystical awe and mastery of nature that constitutes the human condition,” Blau muses. “Humans escape from the confines of the earth to see and record things that have never been seen or recorded before – the impossible.”
The first cosmonaut to cast a vote from space was actually a cosmonaut (individuals trained by the Russian Space Agency for space travel) who flew from the Salyut-1 space station to the 24th Congress of the Communist Party of the Soviet Union in 1971. I voted.
Subsequently, three more cosmonauts voted in the 1989 Soviet parliamentary elections from the Mir space station, which operated in low Earth orbit from 1986 to 2001. Their votes were not confidential, and they communicated their choices to ground controllers instead of using regular communications. This public vote could have been great publicity for those seeking support from space.
However, when it came to democratic voting with secure ballots, there was a challenge. In November 1996, during the United States presidential election featuring candidates Bill Clinton, Bob Dole, and Ross Perot, astronaut John Blaha, a U.S. citizen residing in Texas, wanted to vote. As he was on the Mir space station, NASA facilitated secure communications for his voting process. Yet, the Texas Secretary of State intervened due to the lack of provisions in Texas election law for electronic voting, preventing Mr. Blaha from casting his vote.
This situation led to the signing of a new bill in 1997 by Governor George W. Bush, explicitly allowing voting from space. Astronaut David Wolfe’s first vote took place in a local election in Texas.
Since then, astronauts have been able to vote from space, with most opting to do so. The majority of astronauts relocated to Texas for training, enabling them to vote legally under the new law. There are also provisions for residents of other states to vote through collaboration with NASA.

So, how do astronauts actually vote from space? Before their launch, all military personnel overseas must register for a federal postcard application. When it’s time to vote, NASA’s Johnson Space Center sends test ballots provided by the relevant county clerk to the astronauts. The astronauts use a training computer to complete the ballot, ensuring it is correctly received on Earth. The authentic ballot, along with credentials from the county clerk, is securely transmitted to the astronaut’s computer for electronic completion, then sent to NASA.
The ballot transmission occurs through NASA’s Tracking Data Relay Satellite (TDRS) to the White Sands Complex in New Mexico, and then via landline to Mission Control at Johnson Space Center. The completed ballot is emailed as a password-protected secure file to the county clerk for formalization.

With the upcoming US presidential election in November 2024, stranded astronauts Sunita Williams and Butch Wilmore may still be in space, necessitating the need for them to vote from space. Originally scheduled to return in June 2024, delays have extended their stay, with their planned return now set for February 2025 by SpaceX.
The crucial question remains: did they submit the federal postcard application for voting prior to launch? Failure to do so may still prevent them from voting.

Our planet’s new small satellite, 2024 PT5, arrived in Earth’s orbit on September 29, 2024.
2024 PT5 is scheduled to capture a temporary flyby from September 29th to November 25th in 2024. Image credit: University of Colorado.
2024 PT5 was discovered by the Asteroid Earth Impact Final Warning System in Sutherland, South Africa on August 7, 2024.
This near-Earth asteroid is about 10 meters (33 feet) in diameter and follows an orbit similar to that of 2022 NX1.
2024 PT5 will become a mini-Earth satellite on September 29 and return to heliocentric orbit 56.6 days later on November 25.
“Near-Earth objects like this offer a glimpse into the formation process of the solar system,” said astrophysicist Dr. Nico Cappellutti. University of Miami.
“Most asteroids in our solar system are rocky remnants left over from the formation of our solar system.”
2024 PT5 is part of Arjuna, an asteroid belt made up of space rocks that follow an orbit around the sun very similar to Earth’s orbit.
“So sometimes they can remain temporarily trapped in our gravitational field,” Dr. Cappellutti said.
“Bringing them this close is a fascinating opportunity.”
“The asteroid, the size of a school bus, is too faint and small to be seen with the naked eye or with amateur telescopes, but its two-month stay around Earth has reinforced our intense interest in space rocks. It helps maintain.”
Two years ago, in what was called the first test of the planetary defense system, NASA crashed a spacecraft into the giant space rock Dimorphos, which could change direction if the asteroid was on a collision course with Earth. proved something.
Private companies also want to send spacecraft to asteroids in hopes of mining the precious metals they contain.
“Asteroids are classified based on their orbits and their contents,” said Dr. Bertrand Dano, also from the University of Miami.
“Some are made entirely of stone, while others contain high concentrations of rare metals, such as platinum and gold for electronics, nickel and cobalt for catalysts and fuel cell technology, and, of course, iron.”
“Mining asteroids is not far off. There are currently millions of asteroids in our solar system, about 2 million of which are larger than 1 km.”
“The resources it contains are a new dream for El Dorado, and there are several companies currently betting on it.”
“Recent missions to rendezvous with, orbit and land on asteroids have proven that space mining may be only a matter of time.”
“However, proceeding with asteroid mining will require huge investments, from the mining equipment that needs to operate in a vacuum to the technology needed to transport the extracted minerals to Earth.”
“And then there’s the spacecraft itself. A dedicated ship that would travel to an asteroid for the purpose of extracting minerals from the asteroid would probably be a robotic ship.”
“A trip to Mars would take about eight months under the best conditions. The space and equipment needed to support life would be put to good use as storage for backup equipment and resources.”

In a new study, astronomers compared high-resolution images of Uranus from the NASA/ESA Hubble Space Telescope with more distant views from NASA’s New Horizons spacecraft. Their results could serve as “ground truth” observations to use as a baseline for interpreting exoplanet direct imaging data from future observatories.

Direct imaging of exoplanets is an important technique for understanding their potential habitability and provides new clues to the origin and formation of our own solar system.
Astronomers use both direct imaging and spectroscopy to collect light from observed planets and compare their brightness at different wavelengths.
However, exoplanets are notoriously difficult to image because they are so far away.
Their images are just pinpoints, so they aren’t as detailed as our close-up view of the world around the sun.
Astronomers can also directly image exoplanets only in “partial phase,” when only part of the planet is illuminated by its star as seen from Earth.
Uranus was an ideal target as a test to understand future long-range observations of exoplanets by other telescopes for several reasons.
First, many known exoplanets are gas giants with similar properties. Also, at the time of the observation, New Horizons was on the far side of Uranus, 10.5 billion kilometers (6.5 billion miles) away, and was able to study the twilight crescent moon. This is not possible from Earth.
At that distance, New Horizons’ view of the planet was just a few pixels wide of its color camera (Multispectral Visible Imaging Camera).
Meanwhile, Hubble’s high resolution allowed it to see atmospheric features such as clouds and storms on the dayside of the gas world from its low orbit, 2.7 billion kilometers (1.7 billion miles) from Uranus. .
Samantha Hassler, an astronomer at the Massachusetts Institute of Technology, said: “We expected Uranus to look different depending on the observation filter, but New Horizons data taken from different perspectives actually show that Uranus looks different than expected.'' It turned out to be much darker than that.”
The gas giant planets in our solar system have dynamic and variable atmospheres with changing cloud cover. How common is this in exoplanets?
Knowing the details of what Uranus’ clouds looked like from Hubble will allow researchers to test what they can interpret from New Horizons’ data.
In the case of Uranus, both Hubble and New Horizons observed that the brightness does not change as the planet rotates. This indicates that the cloud characteristics are not changing due to the rotation of the planet.
But the significance of New Horizons’ detection has to do with how the planet reflects light at a different phase than what Hubble and other observatories on or near Earth can see.
New Horizons showed that exoplanets can be dimmer than predicted at partial and high phase angles, and that their atmospheres reflect light differently at partial phase.
“The groundbreaking New Horizons study of Uranus from a vantage point that cannot be observed by any other means adds to the mission’s treasure trove of new scientific knowledge and, like many other data sets obtained on the mission, will Dr. Alan Stern, Principal Investigator of New Horizons and Research Scientist at the Southwest Research Institute, said:
“NASA’s next Nancy Grace Roman Space Telescope, scheduled to launch by 2027, will use a coronagraph to block out starlight and directly observe gas giant exoplanets,” Hassler said. Ta.
“NASA’s Habitable World Observatory, in its early planning stages, will be the first telescope specifically designed to search for biosignatures in the atmospheres of rocky Earth-sized planets orbiting other stars. .”
“Studying how known benchmarks like Uranus appear in distant images will help us have more solid expectations as we prepare for these future missions. And it will help our It’s critical to success.”

Hubble's Wide Field Camera 3 (WFC3) has captured a striking new image of the grand design spiral galaxy NGC 5248.
This Hubble image shows the Grand Design spiral galaxy NGC 5248, located approximately 42 million light-years away in the constellation Bootes. The color images were created from separate exposures taken in the visible, ultraviolet, and near-infrared regions of the spectrum using Hubble's WFC3 instrument. Six filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

NGC5248 It is located in the constellation Bootes, about 42 million light years away.
This spiral galaxy, also known as Caldwell 45, LEDA 48130, UGC 8616, IRAS 13353+0908, and TC 830, has a diameter of 95,000 light years.
beginning discovered It was discovered on April 15, 1784 by German-born British astronomer William Herschel and is a member of the NGC 5248 galaxy group.
NGC 5248 has an apparent magnitude of 10, so it doesn't appear very bright, but it can be spotted with a small telescope.
The galaxy is noteworthy Because of the nuclear ring, which has “hot spots” of starburst activity.
“NGC 5248 is one of the so-called 'grand design' spirals, with prominent spiral arms extending from near the center through the disk,” Hubble astronomers said in a statement.
“There is also a faint bar structure in the center between the inner edges of the spiral arms, which is less obvious in this visible-light portrait from Hubble.”
“Features like this that break a galaxy's rotational symmetry have profound effects on how matter moves through it and ultimately on its evolution over time.”
“They can supply gas from the outer reaches of the galaxy to the inner star-forming regions and even to the black hole at the center of the galaxy, where it can start an active galactic nucleus.”
“These gas flows have significantly shaped NGC 5248, with many bright regions of intense star formation spread throughout the disk and dominated by populations of young stars.”
“This galaxy has two very active ring-like starburst regions filled with young star clusters around its core.”
“While these 'nuclear rings' are noteworthy enough, nuclear rings usually tend to prevent gas from penetrating further into the center of the galaxy.”
“The fact that NGC 5248 has a second ring inside the first shows how powerful its flow of matter and energy is.”
“Due to its relatively close proximity and highly visible starburst region, this galaxy is a target for professional and amateur astronomers alike.”
TThe first expansion story for Bethesda’s space RPG comes after a year of updates that have fixed the game’s flaws. Quest-breaking bugs are gone, there are vehicles for easier planetside travel, city maps are improved, and a 60fps mode is added for Xbox Series X players. However, NPCs still feel stiff and there are many loading screens. Despite this, the Shattered Space expansion aims to build upon the game’s progress.
Bethesda realized that traveling through space via cutscenes was lackluster, so Shattered Space mostly takes place on a single map. The story revolves around the Varoon family, a cult of space serpent worshippers. Players embark on a mission to save a civilization hit by a catastrophe, encountering various tasks and challenges along the way.
Tasks range from interstellar travel to defeating phantoms and mundane chores. While reminiscent of classic Bethesda RPGs, many tasks lack excitement and are hindered by clunky movement mechanics.
Exploring the planet’s landscape can be frustrating due to impassable rocks and lack of interesting discoveries. The gameplay lacks the depth and immersion found in Bethesda’s previous titles.
The attempt to introduce cosmic horror elements falls short, reverting to typical gunfights and loot collection. Unreliable quest markers make the game frustrating, overshadowing the engaging main story and visual appeal of the game.
Shattered Space offers more of the same experience as Starfield, lacking the variety of spaceflight. Despite its flaws, there is potential for improvement in future updates, but a full sequel may be needed to address fundamental issues. The core brilliance of Starfield remains unfulfilled, leaving room for growth.
According to some researchers, the moon may have been captured during a close encounter between young Earth and the Earth binary (a system consisting of the moon and other rocks). new paper Published in Planetary Science Journal.
Darren Williams and Michael Zugger explored the concept of collisionless binary exchange for capturing large satellites (comparable to or larger than the Moon) around Earth-mass objects inside and outside the solar system.
During six missions to the Moon from 1969 to 1972, Apollo astronauts collected more than 360 kg (800 pounds) of lunar rocks and soil.
Chemical and isotopic analysis of the material showed it to be similar to rocks and soils on Earth. It was found to be calcium-rich, basaltic, and dated to about 60 million years after the formation of the solar system.
Using that data, planetary scientists gathered at the Kona conference in Hawaii in 1984 reached a consensus that the moon formed from debris after it collided with a young Earth.
“The Kona conference set the story for 40 years,” said Darren Williams, a professor at Penn State University.
“But questions still remained. For example, a moon formed by a collision of planets, with the debris clumped together in a ring, should orbit above the planet's equator. Earth's moon should orbit above the planet's equator. It's circling around.
“The moon is more in line with the sun than the Earth's equator.”
“In an alternative binary exchange capture theory. Earth's gravity separated the binary star and latched onto one of the objects, the moon, which became a satellite orbiting its current plane.”
“There is evidence that this is happening elsewhere in the solar system.”
“The leading hypothesis in this field is that Triton, the largest of Neptune's moons, was drawn into orbit from the Kuiper belt, where one in 10 is thought to be a binary star. There is.”
“Triton orbits Neptune in a retrograde orbit, moving in the opposite direction of the planet's rotation.”
“Its orbit is also highly tilted, making an angle of 67 degrees from Neptune's equator.”
Professor Williams and Professor Michael Zager of Pennsylvania State University argue that Earth could have captured an even larger satellite than the moon, an object the size of Mercury or Mars, but the resulting orbit would not be stable. It was determined that there was a possibility that the
The problem is that the Moon's “capture” orbit started out as an elongated ellipse, not a circle.
Over time, the shape of the orbit changed under the influence of extreme tides.
“Today Earth's tides are more advanced than the Moon's,” Professor Williams said.
“The high tide accelerates the orbit. It gives it a pulsation and gives it a little bit of a boost. Over time, the moon moves away a little bit.”
When the Moon approaches the Earth, the effect is reversed, as it was immediately after capture.
By calculating tidal changes and the size and shape of the orbit, the researchers determined that the moon's initial elliptical orbit had shrunk over a timescale of several thousand years.
The orbit also became more circular, until the moon's rotation became fixed in its orbit around the Earth, as it is now.
“At that point, the tides likely reversed and the moon began to gradually move away,” Professor Williams said.
“Each year, the Moon moves 3 centimeters away from Earth. At its current distance from Earth – 385,000 km (239,000 miles) – the Moon feels a significant pull from the Sun's gravity.”
“The moon is so far away right now that both the sun and Earth are competing for your attention. They're both being pulled by it.”
Mathematically, the researchers calculated, a satellite captured in a binary exchange could behave similarly to Earth's moon. However, it is not certain whether this is the origin of the moon.
“No one knows how the moon formed,” Professor Williams says.
“For the past 40 years, we've had one possibility as to how it got there.”
“Now we have two. This opens up a treasure trove of new questions and opportunities for further research.”

of NASA/ESA Hubble Space Telescope It has provided astronomers with a detailed new image of the barred spiral galaxy NGC 5668.
In this image of the barred spiral galaxy NGC 5668, the Hubble Space Telescope was used to survey the area surrounding a Type II supernova event called SN 2004G to study the types of stars that end their lives as supernovae. The color image is composed of near-infrared and visible light observations by the Hubble Space Telescope's Advanced Camera for Surveys (ACS). Two filters were used to sample different wavelengths. The colors are obtained by assigning a different color to each monochromatic image associated with an individual filter. Image courtesy of NASA / ESA / Hubble / C. Kilpatrick.
NGC 5668 It is located in the constellation Virgo and is about 90 million light years away from Earth.
This galaxy, also known as IRAS 14309+0440, LEDA 52018, and UGC 9363, Found It was discovered on April 29, 1786 by German-born British astronomer William Herschel.
NGC 5668 belongs to two galaxy groups: the NGC 5638 group and the NGC 5746 group.
“At first glance, NGC 5668 does not appear to be a remarkable galaxy,” the Hubble astronomers said.
“It has a diameter of about 90,000 light-years and is roughly the same size and mass as our own Milky Way galaxy. It faces almost head-on, revealing open spiral arms made up of irregular, cloud-like patches.”
“One striking difference between the Milky Way and NGC 5668 is that new stars are forming 60 percent faster in this galaxy.”
“This confirms a galaxy with swirling clouds and gas flows, and bad weather that creates the perfect conditions for new star formation.”
Astronomers have identified two main drivers of star formation in NGC 5668.
“First, this high-quality Hubble Space Telescope snapshot reveals a central bar,” the researchers said.
“Although it may appear slightly elliptical rather than truly bar-shaped, it is likely to influence the galaxy's star formation rate, similar to the bar-like structure at the centers of many spiral galaxies.”
“Second, a high-velocity hydrogen gas cloud has been tracked moving perpendicularly between the galaxy's disk and the faint, spherical halo that surrounds it.”
“They are produced by the powerful stellar winds of hot, massive stars, which feed gas into new star-forming regions.”
“The elevated star formation rate in NGC 5668 is accompanied by a corresponding abundance of supernova explosions,” the researchers said.
“It has been discovered three times in our galaxy, in 1952, 1954, and 2004.”
The Hubble team has released a striking new photo taken with the NASA/ESA Hubble Space Telescope of NGC 346, an open star cluster in one of our Milky Way galaxy’s closest neighbors.
This Hubble Space Telescope image shows the open star cluster NGC 346, located about 210,000 light-years away in the constellation Sigurd. Image courtesy of NASA/ESA/C. Murray, Space Telescope Science Institute/Gladys Kober, NASA, and The Catholic University of America.
NGC 346 is located in the constellation Tucana and is about 210,000 light-years away.
Also known as ESO 51-10, Kron 39, and Lindsay 60, the star cluster was discovered on August 1, 1826, by Scottish astronomer James Dunlop.
NGC 346 is part of the Small Magellanic Cloud, a dwarf galaxy that is a satellite of the Milky Way galaxy.
The cluster was formed approximately 3 million years ago, has a diameter of 150 light years, and a mass 50,000 times that of the Sun.
“NGC 346’s hot stars are unleashing torrents of radiation and energy outflows that are eating away at the dense gas and dust of the surrounding nebula N66,” Hubble astronomers said in a statement.
“Dozens of hot, blue, high-mass stars shine within NGC 346, and the cluster is thought to contain more than half of the known high-mass stars in the entire Small Magellanic Cloud.”
The Hubble Space Telescope has previously observed NGC 346, but this new image shows the cluster in ultraviolet light, along with visible light data.
“Ultraviolet light helps us understand star formation and evolution, and Hubble is the only telescope capable of sensitive ultraviolet observations thanks to its sharp resolution and its location above the ultraviolet-blocking atmosphere,” the astronomers write.
“These particular observations were collected to learn more about how star formation shapes the interstellar medium – the gas distributed throughout seemingly empty space – in metal-poor galaxies like the Small Magellanic Cloud.”
“Elements heavier than hydrogen and helium are called ‘metals’, and the Small Magellanic Cloud has a lower metal content than most of the Milky Way.”
“This situation serves as an excellent example of a galaxy similar to those that existed in the early universe when there were few heavy elements to take up.”
yesIn front of your ears Star WarsVideo game designers began exploring intergalactic dogfights in 1962. spacewar!The first proper computer game, , was a rudimentary but influential attempt: two skinny triangles spiraling around a star's gravity well and firing torpedoes at each other. After establishing the medium's basic principles, hundreds of developers attempted to refine and perfect the genre, which has gone in and out of fashion but never completely disappeared. Cygnus It's probably the best production attempt to date. A small studio in Scotland Answering the Impossible Question: What if Steven Spielberg had directed it? Space Invaders?
As a lone warrior, you'll race across an alien planet, attacking UFOs and swirling swarms of purple space jellyfish that fly across the screen, in a style reminiscent of polarity-swapping arcade classics. Ikaruga, Cygnus is a master class in technology: a spaceship hurtles through a remote robot battlefield, rocked by the blasts of thousands of fireworks. The orchestra, frantic one moment, melancholic the next, complementarily backs up the action, which ebbs and flows, with moments of rest between the activity.
Enemies fly through the air or glide along the ground far below, forcing you to switch weapons to focus your attacks on either target. Every few minutes you'll be facing off against a much larger enemy, and you'll need to adjust your angle of attack while dodging their attacks and lunges. Enemies drop chunks of power-ups (you lose one every time you take damage), which can be swapped between a shield system or a weapon system, a slightly tedious complexity that adds an extra layer of strategy.
The game is a formidable challenge, and most players should start on the easiest difficulty level. Laser bullets fall like showers rather than hail, and lives are replenished at reasonable intervals between the seven long levels. It can get repetitive at times, Cygnus's innovative mechanics will no doubt be polarizing among the genre's most dedicated and old-school fans, but for those who approach it with an open mind and deft fingers, it remains a thrilling vision.
NGC 261 is located within the Small Magellanic Cloud, one of the Milky Way's closest neighbors.
This Hubble Space Telescope image shows the diffuse nebula NGC 261, about 200,000 light-years from Earth in the constellation Sivir. Image courtesy of NASA/ESA/LC Johnson, Northwestern University/Gladys Kober, NASA and The Catholic University of America.
NGC 261 It is a diffuse nebula located about 200,000 light years away in the constellation Tetranychus.
The object, also known as Brook 42, ESO 29-12, and IRAS 00447-7322, Found It was discovered on September 5, 1826 by Scottish astronomer James Dunlop.
“The ionized gas burning up from within this diffuse region characterizes NGC 261 as an emission nebula,” the Hubble astronomers said.
“The stars are so hot that they irradiate the surrounding hydrogen gas, giving the clouds a pinkish-red glow.”
The Hubble Space Telescope has turned its keen eye to NGC 261 to study how efficiently stars form within molecular clouds, extremely dense regions of gas and dust.
“These clouds are often composed of large amounts of molecular hydrogen and are the cold regions where most stars form,” the researchers explained.
“But molecular hydrogen is poorly radiative, making it difficult to measure this fuel for star formation in stellar nurseries.”
“Because they're difficult to detect, scientists instead track other molecules present within the molecular cloud.”
“The Small Magellanic Cloud contains a gas-rich environment of young stars, as well as traces of carbon monoxide, which correlates with hydrogen and is a chemical often used to confirm the presence of such clouds.”
“The combined powers of the ACS and WFC3 instruments allowed us to probe the star formation properties of the nebula through its carbon monoxide content at visible and near-infrared wavelengths,” the scientists said.
“This work helps us better understand how stars form in our host galaxy and in our Galactic neighbours.”
Boeing’s Starliner spacecraft is not scheduled to return astronauts from space this year
National Aeronautics and Space Administration (NASA)
It’s official: Butch Wilmore and Sunita Williams will remain aboard the International Space Station until at least February. While it’s a major setback for Boeing’s Starliner, the plane that carried them there, it doesn’t spell doom for the U.S. space program. Rather, it highlights the success of the transition from the government providing the sole rocket to space to a proliferation of commercial spaceflight options.
This is exactly the contingency that NASA’s Commercial Crew Program, which transports astronauts to the ISS using spacecraft built by private companies, was designed to handle. “The Commercial Crew Program deliberately selected two providers for redundancy in preparation for exactly this situation,” he said. Laura Forzigan independent space industry consultant. The two NASA astronauts were originally scheduled to arrive at the ISS aboard Boeing’s Starliner spacecraft on June 5 and return to Earth about a week later. However, issues with the spacecraft resulted in them staying for an extended mission before returning home aboard SpaceX’s Crew Dragon spacecraft instead of the Starliner.
“If they had only picked one provider, it would have been Boeing because SpaceX was a riskier proposition at the time,” Forczyk said, “so in some sense, this is a win for the Commercial Crew program.”
The mission was Starliner’s first manned test flight, and it was rocky from the start: valve leaks and thruster failures on the journey into space forced NASA and Boeing to reconsider whether the spacecraft could safely return astronauts to Earth. Tests of the thrusters on the ground were inconclusive, and there was still a risk of the thrusters failing during the return journey.
The safest alternative would be for astronauts to remain on the ISS until SpaceX’s proven Crew Dragon spacecraft has room to return, which could happen in early 2025. In the meantime, Starliner will autonomously detach from the ISS in September and return to Earth without a crew member while Boeing engineers continue to troubleshoot.
“This was a test mission, but sometimes testing gives you answers that tell you there are things that need to be fixed,” said former NASA astronaut Michael Fossum. statement“Testing doesn’t necessarily prove that everything worked perfectly.”
At a press conference on August 24, NASA Administrator Bill Nelson Though Boeing has been adamant that Starliner will get another chance to carry crew to the ISS, some aren’t so convinced. Boeing’s contract requires that the vehicle isn’t certified for use in real missions until it completes a successful test flight, which it didn’t this time. If NASA requires Starliner to undergo another test flight, Forchik says, the first operational flight could be delayed until 2026 at the earliest. With the ISS scheduled to close around 2030, keeping Starliner ready for active duty may not be worth it.
Without redundancy in the commercial crew program, the failure of Starliner could have left the U.S. without a launch provider entirely. As it stands, SpaceX will continue to shuttle astronauts to and from the ISS. Although Wilmore and Williams will need to stay aboard the ISS for a little longer, they are veteran astronauts with the experience and equipment to quickly jump into daily life in space before returning safely to Earth.
For Wilmore and Williams, the challenges and inconveniences of a long-term stay may not outweigh the excitement of life in orbit. “I know them really well, and I think in some ways they were a little disappointed to be up there in such a short amount of time,” Fossum said. “They both have been on long-term missions aboard the space station before… and they both enjoyed it.”
The NASA/ESA Hubble Space Telescope captured this stunning image of the Pegasus dwarf elliptical galaxy, a moon of the Andromeda galaxy.
The Pegasus dwarf elliptical galaxy is located about 959,000 light-years away from the Andromeda galaxy. Image credit: NASA / ESA / D. Weisz, University of California, Berkeley / Gladys Kober, NASA and The Catholic University of California.
“The Andromeda Galaxy, also known as Messier 31, is the closest large spiral galaxy to the Milky Way and is orbited by at least 13 dwarf moons,” Hubble astronomers said in a statement.
“The Pegasus dwarf spheroidal galaxy is one of these compact galaxies.”
“Dwarf spheroidal galaxies are the faintest and most massive galaxies known,” they explained.
“They tend to have an elliptical shape and a relatively smooth distribution of stars.”
“Dwarf spheroidal galaxies are typically devoid of gas and contain mostly old and intermediate-stage stars, although some have recently undergone a small amount of star formation.”
The Pegasus dwarf spheroidal galaxy, also known as Andromeda VI, was discovered in 1996 in images from the Second Palomar Observatory Sky Survey (POSS II).
“The galaxy is characterised by a low abundance of heavy elements, leaving very little gas needed to form the next generation of stars, although it still has more than many of the dwarf spheroidal galaxies in our Local Group,” the astronomers said.
“Researchers suspect that Andromeda's gravitational field is stripping away star-forming gas, leaving it with insufficient material to form more than a few generations of stars.”
“By comparison, some of the Milky Way's comparable distant dwarf spheroidal companions contain intermediate-age stars, which may be because the Andromeda Galaxy is so massive and extended that its gravitational influence reaches farther.”
“The jury is still out on how dwarf elliptical galaxies form,” they noted.
“Theories include collisions between galaxies that break off smaller pieces, the gravitational influence of larger galaxies on small, disk-like dwarf galaxies, and processes related to the birth of small systems among dark matter aggregates.”
“Andromeda and the Milky Way are the only galaxies close enough for astronomers to observe these faint satellite galaxies, so clues to their formation come from nearby galaxies like this one.”
“Hubble studied this galaxy as part of a survey of the entire Andromeda moon system to investigate important topics such as dark matter, reionization, and the growth of galactic ecosystems through the ages of the universe.”
Stunning new images taken by the NASA/ESA Hubble Space Telescope show spiral galaxy UGC 3478 in great detail.

3478 posts It is located in the constellation Camelopardalis and is approximately 128 million light years away from Earth.
Also known as LEDA 19228, INTREF 304, IRAS 06280+6342, Seyfert galaxyA type of galaxy centered around an active galactic nucleus (AGN).
“If you look at the long, star-filled spiral arms and the dark threads of dust that crisscross them, your eye may be drawn to a bright spot at the center of UGC 3478,” the Hubble astronomers said.
“This spot is the core of a galaxy, and there's something very special about it: it's a growing massive black hole, what astronomers call an AGN.”
“As with other active galaxies, the brightness seen here hides a supermassive black hole at the galaxy's centre,” the researchers added.
“A disk of gas spirals into this black hole, and as the material collides and heats up, it emits extremely intense radiation.”
“The spectrum of this radiation includes hard X-ray emission, which makes it clearly distinguishable from stars in the galaxy.”
“Despite the strong brightness of the compact central region, the surrounding galactic disk is still clearly visible, making it a Seyfert galaxy.”
“Astronomers know that many active galaxies are far away from Earth because their nuclei are so bright that they stand out next to other fainter galaxies.”
“Located 128 million light-years away, UGC 3478 is Earth's very own neighbour,” the astronomers said.
Two filters were used to sample different wavelengths, and color was generated by assigning a different hue to each monochromatic image associated with an individual filter.
“The data used to create this image come from Hubble Space Telescope surveys of nearby powerful AGNs discovered in such relatively high-energy X-rays and are expected to help us understand how galaxies interact with their central supermassive black holes,” the researchers said.
NASA announced on Saturday that SpaceX will bring home the two astronauts who have been stranded on the International Space Station since early June due to issues with Boeing’s spacecraft. Astronauts Butch Wilmore and Suni Williams will return to Earth aboard SpaceX’s Crew Dragon spacecraft instead of the Boeing Starliner spacecraft. This decision follows months of uncertainty within the space agency regarding the safe return of the crew members on a mission initially planned to last eight days.
The problems with the Starliner spacecraft have posed a significant setback for Boeing’s space program, which has been struggling to keep up with SpaceX. The Starliner program was already over budget and behind schedule before the launch of Wilmore and Williams in June.
Top NASA officials, led by Administrator Bill Nelson, held a formal review in Houston and based their decision on the results of tests conducted in orbit and on the ground. The announcement to choose SpaceX for the astronauts’ return was made during a press conference at NASA’s Johnson Space Center.
Although the return plans have been finalized, Wilmore and Williams will remain on the space station for approximately six more months before coming back in February. NASA revealed that two seats on SpaceX’s next launch, Crew 9, will be left empty to accommodate the astronauts on their return journey.
The Crew 9 mission is scheduled to launch on September 24 from NASA’s Kennedy Space Center in Florida. Meanwhile, the troubled Starliner spacecraft will return to Earth without its crew.
On July 23, 1999, just a few months before I enrolled in college, NASA’s Space Shuttle Columbia launched with a precious cargo. Not only was it carrying a crew led by the first woman, Eileen Collins, its primary purpose was to launch the Chandra X-ray Observatory, a new flagship space telescope. Chandra This was the heaviest payload ever carried by a NASA space shuttle and turned out to be one of the last two missions completed by Columbia before it tragically exploded after launch on February 1, 2003.
Chandra is the first, and so far only, NASA mission named after a person of color. The late theoretical astrophysicist and Nobel Prize winner Subramanian Chandrasekhar was called Chandra by his friends and family. Chandrasekhar, whose last name means “crown of the moon,” made many important contributions to astrophysics. His most important work was discovering the Chandrasekhar limit, the maximum mass a white dwarf remnant can have before it collapses into a black hole.
It's fitting that an X-ray telescope mission should be named after a scientist who has spent his life thinking about the physics of black holes, as X-ray telescopes play a key role in black hole research. X-rays are high-energy light waves, which means they are produced in extremely energetic environments, such as those around black holes, where extreme distortions of space-time cause strong gravitational forces to accelerate particles to extremely high speeds. In other words, when we look at the universe through the lens of X-ray astronomy, rather than the visible wavelengths of traditional telescopes, we see an entirely different universe.
Importantly, X-ray astronomy can't be done from the Earth's surface, because it's blocked by the Earth's atmosphere. That's good for human health, but not so good for astronomers. Chandra is therefore a reminder of just how important it is to keep low Earth orbit debris-free, so we can safely launch space telescopes that perform tasks that are simply beyond the control of the Earth.
I feel like I have grown up with Chandra. And not just because I attended college at Chandra headquarters, now known as the Center for Astrophysics (CfA) in Massachusetts, and was often mistakenly called “Chandra”. One of my lab projects as an undergraduate was to adjust the light-gathering part of Chandra's backup camera. The following year, I wrote my undergraduate thesis under the guidance of Martin Elvis, an expert in X-ray astronomy. My research focused on the particle winds that fly out of galaxies that contain supermassive black holes. I used Chandra data to analyze what structures these galaxies take. It is true that Martin's letter helped me secure admission to at least one PhD program. In other words, without Chandra, my career may never have begun.
I am one of thousands of scientists in the fields of physics and astronomy who can tell similar stories of how Chandra data was the foundation of the early stages of their careers, or how they have dedicated their lives to using Chandra to explore the mysteries of the universe. Laura Lopez Ohio State University has used Chandra for many years to study supernovae. Daniel Castronow a staff scientist at CfA, is doing the same thing. The three of us were postdoctoral fellows at MIT and are from a generation that grew up on the power of the Chandra X-ray Observatory.
Now, after 25 years in orbit, Chandra is under threat – not the reality of space debris and aging equipment, but the political climate. US President Joe Biden's appointees to head NASA recently tried to scale back the project, but the scientific community worked with Congress to save the mission. But things will never be the same. A compromise proposal, which has not yet been signed into law, would drastically cut Chandra's funding and limit its scientific scope. Notably, there is no scientific basis for opposing the plan. Recommendations They have an army of expert advisers, but NASA has cut funding it had already promised to scientists, leaving PhD students and postdocs without enough money to cover living expenses.
Chandra deserves better. And so does its global audience. Thanks to Chandra, we have discovered new neutron stars and learned about their interiors. Our knowledge of black holes has blossomed. We have gained a deeper understanding of stellar life cycles and the history of our galaxy. We have been able to study galaxy clusters and learn how dark matter is distributed within them, putting the Milky Way in context. There is still time to save Chandra, a monument to human ingenuity. The fact that it is still going strong after 25 years should be celebrated and it should be honoured by the continuation of the mission.

UGC 4879 is an irregular dwarf galaxy in the constellation Ursa Major.
Also known as VV124 and LEDA 26142, this galaxy is quite isolated.
It lies 3.6 million light years from our Milky Way galaxy and 3.9 million light years from the Andromeda galaxy.
Dwarf galaxy Leo A, located about 1.6 million light-years away, is UGC 4879's closest neighbor.
This isolation makes UGC 4879 an ideal laboratory to study primordial star formation, without the complications of interactions with other galaxies.
There are only two other galaxies in the Local Group that have a similar, though slightly lower, isolation to UGC 4879: DDO 210 and SgrDIG, which are located in the opposite direction from UGC 4879.
“UGC 4879 is an isolated dwarf galaxy that lies just outside our Local Group of galaxies,” Hubble astronomers said in a statement.
“Because of its isolation, we are studying UGC 4879 to determine whether it is an old, relatively undisturbed galaxy.”
“Theories suggest that the least massive dwarf galaxies may have formed first.”
“If UGC 4879 is a relic from the early universe, it may offer clues about the hierarchy and evolution of galaxies, galaxy clusters, and even the universe itself.”
This image of UGC 4879 combines data from two Hubble observing programs focused on learning more about how dwarf galaxies form and evolve.
Astronomers have created a beautiful image of the barred spiral galaxy UGC 11861 using the NASA/ESA Hubble Space Telescope.

11861 posts It is located in the northern constellation Cepheus and is about 69 million light years away from Earth.
The galaxy, also known as LEDA 67671, IRAS 21557+7301, or TC 609, is classified as a barred spiral galaxy and a candidate active galactic nucleus.
UGC 11861 is Composed It consists of an exponential disk, a central box-shaped structure, and two broad spiral arms.
“The galaxy is actively forming new stars amidst clouds of gas and dark dust grains, visible as glowing blue spots in the outer arms,” Hubble astronomers said in a statement.
“As a result of this activity, three supernova explosions have been observed in and near UGC 11861, in 1995, 1997, and 2011.”
“The first two were both Type II supernovae, the kind that result from the collapse of a massive star at the end of its life.”
“This Hubble image was made from data collected to study a Type II supernova and its environment.”
The color image of UGC 11861 was created from images taken separately in the visible and near-infrared regions of the spectrum. Hubble’s Advanced Camera for Surveys (ACS).
Two filters were used to sample different wavelengths, and color was generated by assigning a different hue to each monochromatic image associated with an individual filter.
“UGC 11861 is located 69 million light-years from Earth, which may seem a very long distance, but it was just the right distance for the Hubble Space Telescope to capture this spectacular photo of the galaxy’s spiral arms and the short, bright bar at its center,” the astronomers wrote.
This overlooked mechanism could allow lightning energy to reach the top of the atmosphere, threatening the safety of satellites and astronauts.
When lightning strikes, the energy it carries can create special electromagnetic waves called whistlers, so named because they can be converted into sound signals. For decades, researchers thought that the whistlers produced by lightning remained confined to altitudes relatively close to the Earth's surface, below about 1,000 kilometers.
now Vikas Sonwalkar and Amani Lady Researchers at the University of Alaska Fairbanks discovered that some whistlers bounce off a layer of the atmosphere filled with charged particles called the ionosphere, which allows whistler waves and the energy they carry to travel up to 20,000 kilometers above Earth's surface—all the way into the magnetosphere, the region of space governed by Earth's magnetic field.
Researchers found evidence of these reflective whistlers in data from the Van Allen Probes, twin robotic spacecraft that measured the magnetosphere between 2012 and 2019. They also found hints of the phenomenon in studies published in the 1960s. Both the old and new data indicate that the phenomenon is very frequent and happens all the time, Reddy said.
In fact, the lightning may be depositing twice as much energy into this region as previously estimated, the researchers say, and this energy charges and accelerates nearby particles, creating electromagnetic radiation that can damage satellites and endanger the health of astronauts.
“Lightning has always been considered a bit of a smaller player. Until 10 years ago, this data wasn't available and we'd never looked at it at this level of detail.” Jacob Bortnick researcher at the University of California, Los Angeles. He says the new study is a call for others to develop a more accurate picture of the magnetosphere.
Establishing the connection between lightning and the magnetosphere is also important because changes in Earth's climate could make lightning storms more frequent, Sonwalker said.
The research team now hopes to analyze data from more satellites to learn more about how lightning-based whistlers are distributed in the magnetosphere and how they are affected by space weather.
Astronomers have used the NASA/ESA Hubble Space Telescope to capture striking new photos of LEDA 12535, a barred spiral galaxy located in the famous Perseus Cluster of galaxies.
This Hubble Space Telescope image shows LEDA 12535, a barred spiral galaxy about 320 million light-years away in the constellation Perseus. The color composite was created from images taken with the Hubble Space Telescope's Wide Field Camera 3 (WFC3) in ultraviolet, visible, and near-infrared light. It is based on data obtained through three filters. The colors are obtained by assigning a different hue to each monochromatic image associated with an individual filter.

LEDA12535 It is located about 320 million light years away in the constellation Perseus.
Also known as MCG+07-07-072 or SDSS J032041.39+424814.8, it is classified as a barred spiral galaxy.
“LEDA 12535 has a highly unusual shape for a spiral galaxy, with thin arms extending from the ends of its barred nucleus and tracing a nearly circular path around the disk,” the Hubble astronomers said.
“Using a common extension of Hubble's basis system, it is classified as an SBc(r) galaxy. The c indicates that the two spiral arms are loosely wound, each completing only a half revolution around the galaxy, and the (r) refers to the ring-like structure they produce.”
“Galactic rings come in a variety of shapes, from merely unusual to rare and astrophysically important.”
“Lenticular galaxies are a type of galaxy that lies intermediate between elliptical and spiral galaxies,” the astronomers added.
“Unlike elliptical galaxies, they feature large disks but lack spiral arms.”
“Lenticular means lens-shaped, and these galaxies often feature a ring-like shape in their disks.”
“The classification of ring galaxies, on the other hand, is only applied to unusual galaxies with a round ring of gas and star formation that closely resembles spiral arms but is either completely detached from the galactic core or lacks a visible core at all.”
“They are thought to have formed from the collision of galaxies.”
“Finally, there is the famous gravitational lensing, where the ring is actually a distorted image of a distant background galaxy, formed by the 'lensing' galaxy bending the light around it.”
“The ring-shaped images, called Einstein rings, can only form if the lensed galaxy and the photographed galaxy are perfectly aligned.”
The International Space Station (ISS) is nearing the end of its lifespan, with agencies around the world planning to decommission it around 2030. After nearly 24 years of continuous use by astronauts from the U.S., Russia, Europe, Japan, Canada, and many other regions, the giant orbiting spacecraft is showing its age, and it’s nearly time to bring it down before its aging parts are destroyed in far more dangerous ways (see Inside NASA’s Ambitious Plan to Crash the ISS to Earth).
The effort to keep such a huge research facility in orbit has been controversial, with some saying it’s a waste of money and that it should have been taken off orbit long ago. Critics claim that the facility hasn’t lived up to all expectations and that the scientific results from research on the space station don’t contribute enough to problems on Earth. These criticisms may or may not be true, but they miss the point.
The ISS has always symbolized the possibility of a better world of peace and cooperation as a global collaboration in a very challenging adventure in space. Its two major stakeholders, the United States and Russia, have long been at odds on the ground, yet their astronauts continue to work together on the space station to increase global knowledge and reach into the solar system. The ISS is a symbol of humanity working towards a common goal.
With the ISS gone, it will be nearly impossible to see the same view again. NASA and other space agencies have their eye on the Moon, where the possibility of building an international astronaut village there, while promising, remains a pipe dream for now. The ISS, a prime example of international cooperation, will burn up in the atmosphere and sink into the ocean. Its loss will have ripples that go beyond space science. It would represent a decline in the global cooperation needed to address the big challenges the world currently faces, such as climate change, and is a loss we should all mourn.
NASA is considering keeping its two astronauts there until February as they make their way to the International Space Station after the Boeing spacecraft encountered problems during the flight.
NASA said Wednesday it was still considering options for how to return astronauts Butch Wilmore and Suni Williams safely to Earth and that no plans had been made yet, but officials acknowledged more openly than before that it may decide to use a SpaceX capsule instead.
“Our first option is to return Butch and Suni aboard Starliner,” Steve Stich, NASA’s commercial crew program manager, said at a press conference Wednesday. “But we are making the necessary plans to ensure we have other options and are working with SpaceX to ensure we are prepared to respond.”
Wilmore and Williams arrived at the space station on June 6 on the first crewed test flight of Boeing’s Starliner spacecraft. The original plan was to stay in space for about a week. But a problem with five of Starliner’s thrusters caused the spacecraft’s propulsion system to leak helium, leaving the astronauts stranded in space for more than two months while engineers on the ground gather data on the problem and attempt to troubleshoot it.
The mission was planned as the final step before Boeing is approved to launch regular crewed flights to the ISS, a process whose fate is now up in the air.
NASA gave no indication of when astronauts might return in the Boeing capsule, but Stich said a final decision would need to be made by mid-August.

Meanwhile, the launch of one of SpaceX’s Dragon spacecraft, which was scheduled to deliver a new crew of four to the space station later this month, has been postponed to give NASA and Boeing more time to address issues with the Starliner.
SpaceX mission (Crew 9) NASA officials said they could change plans to send just two crew members into space on the spacecraft instead of four, and use the capsule to bring Wilmore and Williams home.
Ken Bowersox, associate administrator for NASA’s Space Operations Mission Directorate, said there had been disagreements over how to bring the astronauts home safely.
“We have to admit that when we have disagreements, it’s not fun,” Bowersox said. “Those discussions can be painful, but that’s what makes us a good organization, and it helps us make good decisions in the future when we get to that point, and I don’t think we’re that far away.”
If Wilmore and Williams were to return to Earth in a separate spacecraft, mission managers could adjust Starliner’s software to detach it from the space station and return to Earth without a crew member, Stich said.
Boeing officials did not attend the briefing, but a company representative said in a statement that “we remain confident in Starliner’s capabilities and flight principles.”
“Should NASA decide to modify the mission, we will take the necessary steps to prepare Starliner for an uncrewed return,” the statement said.
The thruster problem occurred as Starliner approached the space station in June, forcing a delay in the docking process. Meanwhile, the helium leak was already on mission managers’ radar before launch, who said at the time that the leak was unlikely to affect the mission or the safety of astronauts.
NASA and Boeing engineers have been trying to replicate on-orbit conditions with a test engine at NASA’s White Sands Test Facility in New Mexico, and mission managers have also conducted two “hot-fire” tests in space, in which the capsule’s thrusters were briefly fired while docked to the space station.
Stich said Wednesday that tests showed that small Teflon seals expand under high temperatures, possibly contributing to the thruster failure. When the seals expand, they likely block the flow of propellant to the thrusters, he said.
Further testing is needed to understand the cause of the potential blockage and why it went undetected during the recent hot-fire test. Last week, NASA reported that the thrusters used to steer the spacecraft in orbit and guide it into position before re-entering Earth’s atmosphere appeared to be stable.
“This gives us a lot of confidence in the thruster, but we can’t prove with complete certainty that what we’re seeing in orbit is exactly what we’re replicating on the ground,” Stich said.
The recent Starliner debacle has been a blow to Boeing, especially since the program was already years behind schedule and more than $1.5 billion over budget before astronauts even launched.
Boeing and SpaceX developed the space capsule as part of NASA’s Commercial Crew Program, an effort launched more than a decade ago to help private companies build new spacecraft to carry astronauts to low Earth orbit. The program began after NASA retired the Space Shuttle.
SpaceX has been ferrying astronauts to the International Space Station since 2020.
