New Webb Telescope photos show off the Exposed Cranium Nebula

It's always a fun day for the space nerds when a NASA team has new images to share from the James Webb Space Telescope. Today's pair has brains on the brain, with a look at the fittingly named Exposed Cranium Nebula. More officially, this cloud of space dust and debris is known as Nebula PMR 1. The images shared today may capture a moment in the final stages of a star, as well as giving hints as to how the nebula got its brain-like shape.  

"The nebula appears to have distinct regions that capture different phases of its evolution — an outer shell of gas that was blown off first and consists mostly of hydrogen, and an inner cloud with more structure that contains a mix of different gases," NASA's blog post reads. The dark line that runs vertically through the nebula, giving it the cranial appearance, could be the result of "an outburst or outflow from the central star, which typically occurs as twin jets burst out in opposite directions." Both Webb's Near-Infrared Camera (NIRCam) and its Mid-Infrared Instrument (MIRI) were used to document the nebula.

Orbital AI data centers could work, but they might ruin Earth in the process

At the start of the month, Elon Musk announced that two of his companies — SpaceX and xAI  — were merging, and would jointly launch a constellation of 1 million satellites to operate as orbital data centers. Musk's reputation might suggest otherwise, but according to experts, such a plan isn't a complete fantasy. However, if executed at the scale suggested, some of them believe it would have devastating effects on the environment and the sustainability of low Earth Earth orbit.     

Musk and others argue that putting data centers in space is practical given how much more efficient solar panels are away from Earth's atmosphere. In space, there are no clouds or weather events to obscure the sun, and in the correct orbit, solar panels can collect sunlight through much of the day. In combination with declining rocket launch costs and the price of powering AI data centers on Earth, Musk has said that within three years space will be the cheapest way to generate AI compute power. 

Ahead of the billionaire's announcement, SpaceX filed an eight-page application with the Federal Communications Commission detailing his plan. The company hopes to deposit the satellites in this massive cluster in altitudes ranging between 500km and 2000km. They would communicate with one another and SpaceX's Starlink constellation using laser "optical links." Those Starlink satellites would then transmit inference requests to and from Earth. To power the entire effort, SpaceX has proposed putting the new constellation in sun-synchronous orbit, meaning the spacecraft would fly along the dividing line that separates the day and night sides of the planet. 

What a data center would endure in orbit

Almost immediately the plan was greeted with skepticism. How would SpaceX, for instance, cool millions of GPUs in space? At first glance, that might seem like a weird point to get hung up on — much of space being around -450 Fahrenheit — but the reality is more complicated. In the near vacuum of space, the only way to dissipate heat is to slowly radiate it out, and in direct sunlight, objects can easily overheat. As one commenter on Hacker News succinctly put it, "a satellite is, if nothing else, a fantastic thermos."

Scott Manley, who, before he created one of the most popular space-focused channels on YouTube, was a software engineer and studied computational physics and astronomy, argues SpaceX has already solved that problem at a smaller scale with Starlink. He points to the company's latest V3 model, which has about 30 square meters of solar panels. "They have a bunch of electronics in the middle, which are taking that power and doing stuff with it. Now, some of that power is being beamed away as radio waves, but there's a lot of thermal power that's being generated and then having to be dissipated. So they already have a platform that's running electronics off of power, and so it's not a massive leap to turn into something doing compute."

The larger V3 @Starlink satellites that will deploy from Starship will bring gigabit connectivity to users and are designed to add 60 Tera-bits-per-second of downlink capacity to the Starlink network.

Kevin Hicks, a former NASA systems engineer who worked on the Curiosity rover mission, is more skeptical. "Satellites with the primary goal of processing large amounts of compute requests would generate more heat than pretty much any other type of satellite," he said. "Cooling them is another aspect of the design which is theoretically possible but would require a ton of extra work and complexity, and I have doubts about the durability of such a cooling system."  

What about radiation then? There's a reason NASA relies on ancient hardware like the PowerPC 750 CPU found inside the Perseverance rover: Older chips feature larger transistors, making them more resilient to bit flips — errors in processing caused most often by cosmic radiation — that might scramble a computation. "Binary ones and zeroes are about the presence or absence of electrons, and the amount of charge required to represent a 'one' goes down as the transistors get smaller and smaller," explains Benjamin Lee, professor of computer and information science at the University of Pennsylvania. Space is full of energized particles traveling at incredible velocities, and the latest GPUs are built on the smallest, most advanced processing nodes to create transistor-dense silicon. Not a great combination.

"My concern about radiation is that we don't know how many bit flips will occur when you deploy the most advanced chips and hundreds of gigabytes of memory up there," said Professor Lee, pointing to preliminary research by Google on the subject. As part of Project Suncatcher, its own effort to explore the viability of space-based data centers, the company put one of its Trillium TPUs in front of a proton beam to bombard it with radiation. It found the silicon was "surprisingly radiation-hard for space applications." 

While those results were promising, Professor Lee points out we just don't know how resilient GPUs are to radiation at this scale. "Even though modern computer architectures can detect and sometimes correct for those errors, having to do that again and again will slow down or add overhead to space-based computation," he said.   

Space engineer Andrew McCalip, who's done a deep dive on the economics of orbital data centers, is more optimistic, pointing to the natural resilience of AI models. "They don't require 100 percent perfect error-free runs. They're inherently very noisy, very stochastic," he explains, adding that part of the training for modern AI systems involves "injecting random noise into different layers."   

Even if SpaceX could harden its GPUs against radiation, the company would still lose satellites to GPUs that break down. If you know anything about data centers here on Earth, it's that they require constant maintenance. Components like SSDs and GPUs die all the time. Musk has claimed SpaceX's AI satellites would require "little" in the way of operating or maintenance costs. That's only true if you accept the narrowest possible interpretation of what maintaining a fleet of AI satellites would entail.

"I think that there's no case in which repair makes sense. It's a fly till you die scenario," says McCalip. From an economic perspective, McCalip argues the projected death rate of GPUs in space represents "one of the biggest uncertainties" of the orbital data center model. McCalip's put that number at nine percent on the basis of a study Meta published following the release of its Llama 3 model (which, incidentally, measured hardware failures on Earth.) But the reality is no one knows what the attrition rate of those chips will be until they're in space. 

Orbital data centers also likely wouldn't be a direct replacement for their terrestrial counterparts. SpaceX's application specifically mentions inference as the primary use case for its new constellation. Inference is the practical side of running an AI system. It sees a model apply its learning to data it hasn't seen before, like a prompt you write in ChatGPT, to make predictions and generate content. In other words, AI models would still need to be trained on Earth, and it's not clear that the process could be offloaded to a constellation of satellites. "My initial thinking is that computations that require a lot of coordination, like AI training, may end up being tricky to get right at scale up there," says Professor Lee.     

Kessler syndrome

In 1978, a pair of NASA scientists proposed a scenario where low Earth orbit could become so dense with space junk that collisions between those objects would begin to cascade. That scenario is known as Kessler syndrome. 

One estimate from satellite tracking website Orbiting Now puts the number of objects in orbit around the planet at approximately 15,600. Another estimate from NASA suggests there are 45,000 human-made objects orbiting Earth. No matter the number, what's currently in orbit represents a fraction of the 1 million additional satellites Musk wants to launch.  

According to Aaron Boley, professor of physics and astronomy at the University of British Columbia and co-director of the Outer Space Institute, forward-looking modeling of Earth's orbit above 700 kilometers — where part of SpaceX's proposed cluster would live — suggests that area of space is already showing signs of Kessler syndrome. 

While it takes less time for debris to clear in low Earth orbit, Professor Boley says there's already enough material in that region of space where there could be a cascading effect from a major collision. Debris could, in a worst case scenario, take a decade to clear up. In turn, that could lead to disruptions in global communications, climate monitoring missions and more.     

"You could get to the point where you're just launching material in, and you could ask yourself how many satellites can I afford to lose? Can you reconstitute your constellation faster than you're losing parts of it because of debris?" says Boley. "That's a horrible future in terms of the environmental perspective" In particular, it would limit opportunities for humans to fly into low Earth orbit. "Could you operate in it? Yeah, but it would come with higher and higher costs," adds Boley. 

"The entire world is struggling with the problem of how we safely fly multiple mega constellations," says Richard DalBello, who previously ran the Traffic Coordination System for Space (TraCSS) at the US Department of Commerce. Right now, there is no common global space situational awareness (SSA) system, and government and satellite operators are using uncoordinated national and commercial systems that are likely producing different results. At the start of the year, SpaceX lowered the orbit of thousands of Starlink satellites after one of them nearly collided with a Chinese satellite. 

SpaceX has its own in-house SSA system called Stargaze, which it uses to fly its more than 7,000 Starlink satellites. According to DalBello, competing operators can receive SSA data from SpaceX, but to do so they must share their satellite position information. “Assuming data sharing, it is likely Stargaze can make an important contribution to spaceflight safety" says DalBello. “SpaceX is likely to have success with US and other commercial operators, but without the assistance of the federal government, other governments — particularly China — will likely be unwilling to share their satellite and SSA data." 

According to DalBello, the Biden administration was unable to make meaningful progress on the next-generation TraCSS system, in part because Congress was initially reluctant to fund the program. Meanwhile, the current Trump administration hasn't shown interest in advancing the work that began during the president's first term.  

Even if the regulatory situation suddenly changes and the world's governments agree on an international SSA system, SpaceX launching 1 million satellites along the day-night terminator would see the company effectively monopolize one of the Earth's most valuable and important orbits. Professor Boley argues we should view our planet's orbits as a resource that belongs to everyone. "Every time you put a satellite up, you use part of that resource. Now someone else can't use it." 

And as Hicks points out, even a single cascade of colliding satellites would prevent that space from being used for scientific endeavors. "You would have to wait years for that debris to slowly come back into the atmosphere and burn up. In the meantime, that debris is taking up space that could be used for climate monitoring missions or any other types of missions that governments want to launch."   

A blow to the atmosphere

Separately, the constant churn of Starship launches and re-entry of dead satellites would have a potentially dire impact on our planet's atmosphere. "We're not prepared for it," Boley flatly says of the latter. "We're not prepared for what's happening now, and what's happening now is already potentially bad." 

According to Musk's "basic math," SpaceX could add 100 gigawatts of AI compute capacity annually by launching a million tons of satellite per year. McCalip estimates a 100-gigawatt buildout alone would necessitate about 25,000 Starship flights.  

Many of the metals found in satellites, including aluminum, magnesium and lithium, in combination with the exhaust rockets release into the atmosphere, can have complicated effects on the health of the planet. For instance, they can affect polar cloud formations, which in turn can facilitate ozone layer destruction through the chemical reactions that occur on their surfaces. According to Boley, the problem is we just don't know how severe those environmental factors could become at the scale Musk has proposed, and SpaceX has provided us with precious few details on its mitigation plans. All it has said is that its plan would "achieve transformative cost and energy efficiency while significantly reducing the environmental impact associated with terrestrial data centers."   

Even if SpaceX could and does go out its way to mitigate the atmospheric effects of constant rocket flights, those spacecraft still need to be manufactured here on Earth. At one of his previous roles, Hicks studied rocket emissions and found the supply chains needed to build them produce an "order of magnitude" more carbon emissions than the rockets themselves.   

SpaceX plans to fly its new satellites in a sun-synchronous orbit, meaning for much of the year, they'll be sunlit. Each new Starlink generation has been larger and heavier than the one before it, with SpaceX stating in a recent filing that its upcoming V3 model could weigh up to 2,000 kilograms, up from the 575 kilograms of the V2 Mini Optimized. While we don't know the exact dimensions of the company's still-hypothetical AI satellites, they will almost certainly be bigger than their Starlink counterparts. 

SpaceX has done more than most space operators to reduce the brightness of its satellites, but Professor Boley says he expects that this new constellation will be "strikingly bright" when moving through the night sky. In aggregate, he estimates they will almost certainly be harmful to scientific research here on Earth, limiting what terrestrial observatories can see.  

"You're going to see them with the naked eye. You're going to see them with cameras. It's going to be like living near an airport where you see all these things flying over just after sunset and the next couple of hours after sunset," says Manley. "I don't know if I want to have my entire sunset be just a band of satellites constantly shooting overhead."

There are good reasons to make some spacecraft capable of doing AI inference. For instance, Professor Lee suggests it would make orbital imaging satellites more useful, as those spacecraft could do on-site analysis, instead of sending high-resolution files over long distances, saving time in the process. But the dose, as they say, makes the poison.

"There's a lot of excitement about the many possibilities that can be brought to society and humanity through continued access to space, but the promise of prosperity is not permission to be reckless," he says. "At this moment, we're allowing that excitement to overtake that more measured progression [...] those impacts don't just impact outer space but Earth as well."

Watch the NASA SpaceX Crew-12 mission dock with the ISS

The Crew-12 mission, SpaceX’s 20th human spaceflight, launched at 5:15 AM Eastern on February 13 from Cape Canaveral in Florida. It’s expected to dock with the International Space Station today, February 14, at 3:15 PM, and you can watch the event below as it happens. By the time the mission’s Dragon capsule docks with the ISS, it will have traveled approximately 34 hours since lift off. Inside are NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency’s Sophie Adenot and Roscosmos cosmonaut Andrey Fedyaev.

The four spacefarers are joining the three remaining passengers onboard the ISS after Crew-11 flew back to Earth a month earlier than planned. If you’ll recall, NASA made the decision to cut their mission short after one of the crew members had a medical issue that instruments on the ISS aren’t capable of diagnosing. While the crew member was stable, the agency decided to bring the whole mission home out of an abundance of caution.

Crew-12 will be staying on the ISS for eight months and will conduct a number of scientific experiments, including ones related to human health and ones meant to advance technologies for future missions to the moon and Mars. They will study how pneumonia-causing bacteria can lead to long-term heart damage, for instance, and will also look into how a person’s physical characteristics can affect blood flow during spaceflight. NASA’s live coverage for the docking starts at 1:15 PM.

NASA is sending Crew-12 astronauts to the ISS on February 11

The Crew-12 astronauts will soon make their way to the ISS, joining the three remaining spacefarers on board after the previous mission was cut short due to a medical concern. NASA was originally planning a February 15 launch date for the mission, but it has moved it up to February 11. It’s now targeting a liftoff of no earlier than 6:01 AM Eastern that day from Cape Canaveral in Florida. The crew members are already in quarantine, and if everything goes well on launch day, the Dragon capsule they’re on will dock with the orbiting lab at approximately 10:30 AM on February 12.

If you’ll recall, NASA decided to bring Crew-11 members back home on January 15, a month earlier than planned, citing a medical concern with one of the members. While the affected astronaut was stable, the ISS didn’t have the equipment necessary to be able to diagnose them properly. All four members of Crew-11 flew home, leaving the whole space station in the hands of three people, namely NASA astronaut Chris Williams and two cosmonauts for the Russian side. They will be joined by Crew-12’s NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency’s Sophie Adenot and Roscosmos cosmonaut Andrey Fedyaev.

SpaceX recently had to ground its Falcon 9 rocket after an issue with its upper stage for a few days, leaving the Crew-12’s flight schedule in question. But on February 6, the Federal Aviation Administration cleared it for its next flight. NASA will livestream the mission’s prelaunch, launch and docking activities on NASA+, Amazon Prime and on its YouTube channel, with its launch coverage starting at 4AM Eastern time on February 11. You can also bookmark or pin this page to watch the launch below.

NASA will now allow astronauts to take their smartphones to space

Most people wouldn't leave their phones behind when they so much as go for a drive, but NASA astronauts have had to leave their phones on Earth while they went to work 250 miles away at the International Space Station. That is, until now.

In a post on X, NASA Administrator Jared Isaacman shared that the Crew-12 and Artemis II astronauts will be allowed to bring smartphones along for the journey to the ISS and beyond. "We are giving our crews the tools to capture special moments for their families and share inspiring images and video with the world," Isaacman said.

While these won't be the first smartphone images captured in space — that distinction belongs to a trio of miniature phone-based satellites sent into Earth orbit in 2013 which succeeded where the earlier British STRaND-1 project failed. But thanks to the upcoming Artemis II mission, we can look forward to the first smartphone images from the moon's orbit. The March (for now) launch will be the agency's first crewed moon mission since Apollo 17 in 1972.

The crews' personal devices will be far less cumbersome to use than the old Nikon DSLRs they were previously limited to for high-quality still images. Ideally, this means more spontaneous pictures that can be shared with friends and family back on Earth.

NASA moves Artemis 2 launch to March after hydrogen leak during testing

NASA started making the final preparations for the Artemis 2 mission in early January, with the hopes of opening its launch window as soon as February 6. After issues showed up during the mission’s wet dress rehearsal in the early hours of February 3, however, the agency had to push back its earliest launch opportunity to March.

“With more than three years between SLS launches, we fully anticipated encountering challenges. That is precisely why we conduct a wet dress rehearsal. These tests are designed to surface issues before flight and set up launch day with the highest probability of success,” NASA administrator Jared Isaacman said on X.

During a wet dress rehearsal, the spacecraft to be used for a mission is loaded with propellants to simulate the actual preparations and countdown to liftoff. NASA explained that Artemis 2’s Space Launch System, which was already on the launch pad, suffered from a liquid hydrogen leak that its engineers spent hours troubleshooting. They were ultimately able to fill all the rocket’s tanks and started the countdown to launch. But with approximately five minutes left in the countdown, the ground launch sequencer automatically stopped due to a spike in the spacecraft’s liquid hydrogen leak rate.

The agency admits that it has other issues to fix, based on what happened during the rehearsal. It has to make sure that the cold weather doesn’t affect the mission’s equipment during the actual launch in the same way it did in testing . The Orion crew module’s hatch pressurization process took longer than expected, and that should must not happen on launch day. NASA also has to troubleshoot the audio communication channels for its ground teams after they dropped several times during the rehearsal. Artemis’ ground crew will review data from the wet dress rehearsal and address the aforementioned problems. NASA then has to conduct another test to confirm that they were taken care of before announcing the mission’s launch window.

NASA completed a wet dress rehearsal for the Artemis II mission in the early morning hours on Feb. 3. To allow teams to review data and conduct a second wet dress rehearsal, NASA will now target March as the the earliest possible launch opportunity for the Artemis II mission.… pic.twitter.com/jSnCUPLQb6

SpaceX wants to launch a constellation of a million satellites to power AI needs

Elon Musk and his aerospace company have requested to build a network that's 100 times the number of satellites that are currently in orbit. On Friday, SpaceX filed an application with the Federal Communications Commission (FCC) to launch a million satellites meant to create an "orbital data center." This isn't the first time we're hearing of Musk's plans to build an orbital data center, as it was mentioned by company insiders following the news that the CEO was reportedly preparing to take SpaceX public.

According to the filing spotted by PCMag, this data center would run off solar power and deliver computing capacity for artificial intelligence needs. SpaceX is requesting to "deploy a system of up to one million satellites to operate within narrow orbital shells spanning up to 50 km each," as detailed in the filing. According to SpaceX's filing, "orbital data centers are the most efficient way to meet the accelerating demand for AI computing power" since they use "solar power with little operating and maintenance costs."

To give some scale of the astronomical number of satellites SpaceX is asking for, the company recently hit a milestone of the 11,000th Starlink satellite launched. There aren't as many in orbit since the satellites can run into issues, but an unofficial website that tracks Starlink stats claims there are more than 9,600 satellites in orbit as of January 30, 2026. The FCC is likely to whittle down the amount that SpaceX is asking for in its filing, as the federal agency has done in the past. Earlier this month, the FCC approved SpaceX's request to deploy 7,500 more Starlink satellites, following another 7,500 launched in 2022. However, it's much less than the nearly 30,000 amount that SpaceX first asked for in 2020.

Astronomers share new insights about the early universe via the Webb Space Telescope

Researchers using the James Webb Space Telescope have found a galaxy that is offering new data about the early stages of the universe's existence. The latest discovery shared by astronomers is about a bright galaxy dubbed MoM-z14. According to the team, this galaxy existed 280 million years after the Big Bang. 

The sounds like a long time, but in the context of the universe's estimated 13.8 billion years of existence, that's actually one of the closest examples astronomers have found to the Big Bang's occurrence. As a result, MoM-z14 can offer some insights and some surprises about what the early stages of the universe entailed.

"With Webb, we are able to see farther than humans ever have before, and it looks nothing like what we predicted, which is both challenging and exciting," lead author Rohan Naidu of Massachusetts Institute of Technology said. The findings about this galaxy were published in the Open Journal of Astrophysics.

The scientists were able to date MoM-z14 with Webb's Near-Infrared Spectrograph instrument, analyzing how light from the galaxy changed wavelengths as it traveled to reach the telescope. One of the initial questions sparked by this bright galaxy centers on the presence of nitrogen. Some early galaxies, including MoM-z14, have revealed higher nitrogen concentrations than scientists had projected was possible. Another topic of interest is about reionization, or the process of stars producing enough light or energy to permeate the dense hydrogen fog that existed in the early universe. 

“It’s an incredibly exciting time, with Webb revealing the early Universe like never before and showing us how much there still is to discover” said Pennsylvania State University graduate student and team member Yijia Li.

Astronomers discover over 800 cosmic anomalies using a new AI tool

Here's a use of AI that appears to do more good than harm. A pair of astronomers at the European Space Agency (ESA) developed a neural network that searches through space images for anomalies. The results were far beyond what human experts could have done. In two and a half days, it sifted through nearly 100 million image cutouts, discovering 1,400 anomalous objects.

The creators of the AI model, David O'Ryan and Pablo Gómez, call it AnomalyMatch. The pair trained it on (and applied it to) the Hubble Legacy Archive, which houses tens of thousands of datasets from Hubble's 35-year history. "While trained scientists excel at spotting cosmic anomalies, there's simply too much Hubble data for experts to sort through at the necessary level of fine detail by hand," the ESA wrote in its press release.

After less than three days of scanning, AnomalyMatch returned a list of likely anomalies. It still requires human eyes at the end: Gómez and O'Ryan reviewed the candidates to confirm which were truly abnormal. Among the 1,400 anomalous objects the pair confirmed, more than 800 were previously undocumented.

Most of the results showed galaxies merging or interacting, which can lead to odd shapes or long tails of stars and gas. Others were gravitational lenses. (That's where the gravity of a foreground galaxy bends spacetime so that the light from a background galaxy is warped into a circle or arc.) Other discoveries included planet-forming disks viewed edge-on, galaxies with huge clumps of stars and jellyfish galaxies. Adding a bit of mystery, there were even "several dozen objects that defied classification altogether."

"This is a fantastic use of AI to maximize the scientific output of the Hubble archive," Gómez is quoted as saying in the ESA's announcement. "Finding so many anomalous objects in Hubble data, where you might expect many to have already been found, is a great result. It also shows how useful this tool will be for other large datasets."

Earth is having some issues, so let's enjoy the Webb telescope's new nebula image

Sometimes, you just need to give your mind a little vacation. And these days, outer space sounds like as good a destination as any. Thankfully, the James Webb Space Telescope (JWST) is here to give us a dazzling new image of the Helix Nebula.

Discovered in the early 19th century, the Helix Nebula resides in the constellation Aquarius. (Cue The 5th Dimension.) At about 655 light-years away, it's one of Earth's closest planetary nebulae. When zoomed farther out, it's easy to see why it's been nicknamed the Eye of God or Eye of Sauron. This 2004 image from the Hubble telescope illustrates that.

What we're seeing in the nebula is, in a sense, a moment of death that lays the groundwork for a new birth. The dying star (out of frame in the closer new image) sheds its outer layers. As expelled gas and dust cool, they provide raw material that could someday form new stars and perhaps planetary systems.

The new image from Webb's NIRCam (Near-Infrared Camera) provides a much closer, higher-resolution view.

Those pillars you see are called cometary knots, and this image is our best view of those to date. "Here, blistering winds of hot gas from the dying star are crashing into colder shells of dust and gas that were shed earlier in its life, sculpting the nebula's remarkable structure," the ESA wrote in its press release.

The knots' colors represent temperature and chemistry. Hints of blue indicate the hottest gas (energized by ultraviolet light). The yellow regions, where hydrogen atoms form molecules, are farther from the nebula's nucleus (and therefore cooler). On the edges, reddish-orange regions depict the coolest material, where gas thins and dust begins to form.

Senate passes minibus bill funding NASA, rejecting Trump's proposed cuts

After a tumultuous 2025 that saw it lose around 4,000 employees, NASA finally has an operating budget for 2026, and one that largely preserves its scientific capabilities. On Thursday, the Senate passed an appropriations bill funding NASA, alongside the National Science Foundation and a handful of other federal agencies. 

Going into the appropriations process, the president called for a 24 percent year over year reduction to NASA's total operating budget. As part of that plan, the White House wanted to reduce the Science Mission Directorate's funding by nearly half, a move that would have forced NASA to cancel 55 ongoing and planned missions, including efforts like OSIRIS-APEX. The bill effectively rejects President Trump's plan, reducing NASA's total operating budget by just 1.6 percent year over year to $24.4 billion. 

Per the new appropriations, NASA's science budget will stand at $7.25 billion, 1.1 percent less relative to fiscal 2024, while shuffling the remaining funds to focus on different priorities. For instance, the House and Senate allocated $874 million (+8.7 percent) for the agency's heliophysics work; planetary sciences, which oversees missions like New Horizons, was cut to $2.5 billion (-6.5 percent) compared to 2024. At the same time, NASA's STEM engagement office, which the president proposed eliminating, escaped unscathed with its funding maintained at parity.

"It's almost everything we had been asking for, and it's very encouraging to see a House and Senate run by the president's own party agreeing that we need to keep investing in things like NASA science," says Casey Dreier, chief of policy at the Planetary Society, a nonprofit founded by Carl Sagan that advocates for the exploration and study of space. "It contains very clear and direct language that not only is this funding made available to these projects, but that it will be spent on the initiatives that Congress states."

Lawmakers also rejected Trump's effort to scuttle the Space Launch System after its third flight. NASA's heavy-lift rocket is billions of dollars over budget, but remains — as of now — the only spacecraft ready to ferry astronauts to the Moon. Compared to the rest of NASA, the fate of the SLS was never really in doubt. Senator Ted Cruz (R-TX) secured funding for the rocket as part of Trump's Big Beautiful Bill. "I've been saying for a long time you should never underestimate the political coalition behind the SLS, and I think that was very much validated this year," says Dreier. 

More importantly, it appears the Goddard Space Flight Center will be safe from further damage. Over the summer, the future of the facility, known for its work on projects like the James Webb Space Telescope, was put in jeopardy. By some estimates, the campus has lost a third of its staff due to workforce cuts, and dozens of buildings, including some 100 laboratories, have been shut down by management. One of the casualties was NASA's largest library, which houses irreplaceable documents chronicling the history of the space race. As part of a "consolidation" effort, many of those documents will be thrown out.

Under the appropriations bill, the Senate has directed NASA to “preserve all the technical and scientific world-class capabilities at Goddard.” It has also instructed the agency to ensure employees of the Goddard Institute for Space Studies are able to continue their work with "minimal disruption." The New York-based office, one of America's leading climate labs, was sent into limbo last spring after the Trump administration moved to shut it down. 

The bill also provides a lifeline for NASA's to bring back samples of Martian dirt collected by the Perseverance rover. Congress has effectively cancelled the official program tied to that ambition, the Mars Sample Return (MSR), but has set aside $110 million for the agency to continue developing technologies for future science missions to the Red Planet. MSR advocates have argued the mission could lead to significant scientific discoveries, but Dreier notes the program was "ripe for cancellation" after it became mired in mismanagement. 

"I worry MSR now has this stink of bloat, excess cost and threat of overruns that are really going to make it challenging to restart this without having a dramatically different approach," says Dreier, adding that deciding what to do with mission will likely be top of mind for the agency's new administrator, Jared Isaacman. 

The 2026 budget leaves NASA with fewer resources. Even in areas where Congress allocated the same amount of funds as it did in 2024, the agency will need to do more with less due to inflation. Compared to the absolute blood bath that would have been Trump's proposed budget, a marginal funding cut is the best case scenario given the circumstances, but the circumstances remain less than ideal. 

"There will be another presidential budget request coming out in the next couple of months," Dreier said. "They could do this all over again if they wanted to."

In the immediate future, NASA and its employees are at least protected from the potential fallout of another impending government shutdown. Congress has until January 30 to fully fund the federal government, and as of earlier this week, it has yet to find a way forward on appropriations for agencies like the Department of Labor.  

Correction 9:05PM ET: A previous version of this article incorrectly stated Casey Dreier’s surename as Drier. We regret the error.

NASA makes final preparations for its first crewed moon mission in over 50 years

Back in 2024, NASA announced that the Artemis 2 mission was going to be pushed back to April 2026. Now, the agency says it could launch as early as February, with the first flight opportunity being on February 6. NASA is currently making the final preparations for the mission and will soon roll out the Space Launch System (SLS) rocket and the Orion spacecraft to their launch pad at the Kennedy Space Center in Florida. The spacecraft system’s four-mile journey from the assembly building to Launch Pad 39B will take up to 12 hours. NASA is targeting a date no earlier than January 17, with the exact day depending on the weather and on the possible need for additional time to address technical issues.

Artemis 2 is the first crewed mission to the moon since the Apollo program’s final flight in 1972. The 10-day mission will have four astronauts on board who’ll be testing if Orion’s critical life support systems can sustain human passengers on future longer duration missions. They will first orbit the Earth twice before making their way 4,700 miles beyond the far side of the moon. If the SLS and Orion system is rolled out as planned, NASA intends to conduct a wet dress rehearsal at the end of January. The agency will load cryogenic propellants into the rocket and will do a full launch countdown during the rehearsal to prepare for the real event.

NASA delays spacewalk due to a 'medical concern' with a crew member

NASA has postponed an International Space Station (ISS) spacewalk that was scheduled for Thursday. "The agency is monitoring a medical concern with a crew member that arose Wednesday afternoon aboard the orbital complex," the agency wrote. On Thursday, NASA added that ending Crew-11's mission early was on the table.

The unnamed crew member is stable, according to NASA. Space News notes that Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) was heard on an open comms channel on Wednesday requesting a private medical conference with a flight surgeon. However, those requests are routine on the ISS, so we can’t assume the events were related.

"The matter involved a single crew member who is stable," NASA wrote. "Safely conducting our missions is our highest priority, and we are actively evaluating all options, including the possibility of an earlier end to Crew-11's mission."

Crew-11 was scheduled to remain on board the ISS until at least the second half of February. Its replacement, Crew-12, isn't slated to blast off until February 15 at the earliest.

NASA astronauts Mike Fincke and Zena Cardman had planned to exit the airlock on Thursday for the six-and-a-half-hour spacewalk. The short trip’s mission was to install a kit and cables in preparation for a new roll-out solar array that will arrive on a future mission.

The agency said it will provide further updates within 24 hours.
