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.

NASA finally has a leader, but its future is no more certain

After a rudderless year and an exodus of around 4,000 employees due to Trump administration cuts, NASA got what may be its first piece of good news recently. On December 17, the Senate confirmed billionaire Jared Isaacman as the agency's new administrator. He now holds the power to rehabilitate a battered engine of scientific research, or steer it towards even more disruption. 

Considering the caliber of President Trump's other appointees, Isaacman is probably the best candidate for the job. Outside of being a successful entrepreneur, he has flown fighter jets and been to space twice as part of the Inspiration4 and Polaris Dawn private missions. One of those flights saw him complete the first commercial space walk, and travel farther from Earth than any human since the end of the Apollo program.   

"Perfect is the enemy of the good. Isaacman checks a lot of boxes," says Keith Cowing, a former NASA employee and the founder of NASA Watch, a blog dedicated to the agency. "He's passed every requirement to fly in a spacecraft that American astronauts at NASA are required to pass. He also went out of his way to have a diverse crew, and shove as much science as he could in those missions." 

And yet if you're a NASA employee or just someone who cares about the agency's work, there are still plenty of reasons to be concerned for its future. When Trump first nominated Isaacman in the spring, the billionaire wrote a 62-page document detailing his vision for NASA. In November, Politico obtained a copy of that plan, titled Project Athena.

To some insiders, Project Athena painted a picture of someone who, at least at the time when it was written, fundamentally misunderstood how NASA works and how scientific discovery is funded in the US and elsewhere. It also suggests Isaacman may be more open to Trump's NASA agenda than would appear at first glance.   

When asked about the plan by Politico, one former NASA official characterized it as "bizarre and careless." Another called it “presumptuous," given many of the proposed changes to the agency's structure would require Congressional approval. In one section, Isaacman recommended taking “NASA out of the taxpayer funded climate science business and [leaving] it for academia to determine.” In another section, he promised to evaluate the “relevance and ongoing necessity” of every agency center, particularly NASA's iconic Jet Propulsion Laboratory, saying the facility and others must increase the “output and time to science KPI.” 

A lot has changed since Isaacman first wrote that document. It came before the workforce cuts, before the future of Goddard Space Flight Center became uncertain and before Trump surprised everyone by renominating Isaacman. But during his Senate testimony earlier this month, the billionaire said “I do stand behind everything in the document, even though it was written seven months ago. I think it was all directionally correct.”  

He did appear to distance himself from some viewpoints expressed in or inferred by Project Athena, however. Isaacman stated that “anything suggesting that I am anti-science or want to outsource that responsibility is simply untrue.” He also came out against the administration's plan to cut NASA's science budget nearly in half, claiming the proposals would not lead to "an optimal outcome."

One thing is clear, Isaacman is not your typical bureaucrat. "One of the pitfalls of some prior NASA administrators has been that they've shown too much reverence for the internal processes and bureaucratic structure of the agency to the detriment of decision-making and performance," said Casey Drier, chief of space policy at The Planetary Society, a nonprofit that advocates for the exploration and study of space. "Isaacman has positioned himself as the opposite of that. Clearly, that's something that could lead to a lot of political and congressional challenges if taken too far."   

Even if Isaacman doesn't follow through on any of the proposals made in Project Athena, there's only so much a NASA administrator — even one sympathetic to civil servants working under them — can do. 

"Once a budget request goes out publicly, everyone in the administration has to defend it. Anything he does will have to be internal and private," Drier explains. "He never explicitly criticized the administration during his hearing. He's also coming relatively late in the budget process."    

A lot of NASA's future will depend on the White House Office of Management and Budget (OMB), which is responsible for implementing the president's agenda across the executive branch. As a direct result of guidance the OMB issued over the summer, NASA awarded 25 percent fewer new grants in 2025 than it did on average between 2020 and 2024.   

"The OMB has added layers of requirements that scientists now have to go through to spend the money they've already been allocated. The administration has worked against its own stated goals of efficiency," Drier said. "Isaacman can't solve that himself. He can't tell the OMB what to do. That's going to be a serious challenge." 

Looming over everything is the fact NASA still does not have a full-year budget for 2026. Congress has until January 30 to fund NASA and the rest of the federal government before the short-term funding bill it passed on November 12 runs out. "On paper, the official policy of the administration is still to terminate a third of NASA's scientific capability," Drier points out.

There are reasons to be cautiously optimistic. Publicly, both the House and Senate have come out against Trump's funding cuts. And some science missions that were slated to be cancelled, such as OSIRIS-APEX, have been approved for another full year of operations.   

What NASA needs now is someone who will, as Drier puts it, "vigorously advocate" for the agency in whatever way they can. It remains to be seen if that's Jared Isaacman.

Astronomers find mysterious lemon-shaped exoplanet with NASA’s Webb telescope

Space is full of unsolved mysteries, and a team using NASA’s James Webb Space Telescope have recently turned up a doozy. "I remember after we got the data down, our collective reaction was 'What the heck is this?' It's extremely different from what we expected," said Peter Gao of the Carnegie Earth and Planets Laboratory in Washington, a co-author on the study.

The researchers found an exoplanet dubbed PSR J2322-2650b that orbits a small, dense star emitting electromagnetic radiation known as a pulsar. They are an example of a black widow system, where a rapidly spinning pulsar is paired with a smaller astronomical body. A black widow duo isn’t unusual, but this pair has sparked questions about how the exoplanet originally formed.

The exoplanet's proximity to the pulsar and its intense gravitational pull have distorted it into an oblong lemon shape. More unusually, PSR J2322-2650b also has a unique atmosphere comprised mostly of helium and carbon. "Instead of finding the normal molecules we expect to see on an exoplanet — like water, methane, and carbon dioxide — we saw molecular carbon," principal investigator Michael Zhang of University of Chicago said. Given its strange atmosphere, the team isn't certain how the exoplanet formed. "It's very hard to imagine how you get this extremely carbon-enriched composition. It seems to rule out every known formation mechanism," Zhang said. For now, we’ll chalk this up as another mystery of the universe.

The booster for SpaceX’s Starship V3 suffered a gas system failure during testing

SpaceX has confirmed that its third-gen Super Heavy Booster, the first stage of the two-stage Starship system, suffered an explosive gas failure of sorts during testing on Thursday morning. In a post on X, the aerospace company said, "Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing."

There was no propellant inside the booster as the engines were not installed at that point. No injuries were reported and the company shared that personnel are always kept at a safe distance during these types of tests. The company said it will "need time to investigate before we are confident of the cause."

The explosive release of gas, or whatever it was, seems to have blown out the side of the bottom half of the booster. Pictures taken by SpaceX content creators show this in detail. Clips of the livestream show the incident in question at around 4AM on Friday.

The booster is part of the third generation of Starship, SpaceX's enormous and fully reusable rocket designed for high payload capacity. The ship weighs 5,000 tons and towers over 400 feet in height (taller than a 30-story building).

So far, Starship has had 11 successful launches at a cost of over $100 million per launch, and five explosions during testing. While this most recent explosion was fairly benign, previous incidents have seen fiery debris rain down from the sky. SpaceX's ultimate plan for Starship is delivering payloads to the moon and Mars. Most recently, the last iteration of the second-gen Starship had a successful test flight in October. This came after its first ever payload deployment in August.

86 percent of global payload mass sent to space has been carried by SpaceX since 2024, though companies like Blue Origin are investing heavily to compete. According to NASA, the cost per kilogram to launch into space has seen a 95 percent reduction from its shuttle days. The SpaceX Falcon 9 costs 20 times less per kilogram to launch than NASA's space shuttle.

Webb telescope images an aging binary star system in the center of a four-layered cosmic dust shell

NASA’s James Webb Space Telescope has shown us images of space we’d never see otherwise, and one of the latest wonders it has captured is of an unusual star system in our galaxy with what the agency describes as “four serpentine spirals of dust.” Previous observations of the Apep system, named after the Egyptian god of chaos and located around 8,000 light-years away from Eath, showed only one shell. But as you can see in the mid-infrared image captured by Webb above, it actually has four shells, with the most outer one at the very edges of the image. These shells are made out of dense carbon dust emitted by the system’s two Wolf-Rayet stars over the last 700 years.

Wolf-Rayets are massive stars nearing the end of their lives. They’re very rare, and scientists believe there are only a thousand in our galaxy. Apep happens to have two of them. Yinuo Han from Caltech and Ryan White from the Macquarie University in Sydney, Australia have recently published their own papers about the system. They combined measurements from Webb’s observations with years of data from the European Southern Observatory’s Very Large Telescope (VLT) in Chile to determine that the two stars “swing by one another” once very 190 years. The stars then pass close to each other for 25 years, causing their strong stellar winds to collide and cast out huge amounts of carbon-rich dust within that timeframe.

Thanks to the Webb telescope’s observations, they were also able to confirm the presence of a third star in the system that’s gravitationally bound to the two Wolf-Rayets. The third star is a massive supergiant 40 to 50 times bigger than our sun, and it carved a cavity, which looks like a funnel, into the shells. You can see the cavity in the shells in the video below.

Apep’s Wolf-Rayet stars used to be bigger than the supergiant, but they’ve since shed most of their masses and are now only 10 to 20 times the mass of our sun. In time, the two stars will explode into a supernova and possibly turn into a black hole.

Blue Origin’s New Glenn rocket safely made it to space a second time

Blue Origin's New Glenn rocket has completed its second flight, The Washington Post reports. The rocket launched from Florida's Cape Canaveral Space Force Station on Thursday, and successfully separated from its first-stage booster, which later landed on a sea platform Blue Origin calls "Jacklyn."

The launch marks the first time the space startup has been able to catch a New Glenn booster for later reuse. The maiden flight of the rocket in January was successful in the sense that it got New Glenn into space, but Blue Origin wasn't able to save the booster from a watery grave. The company hoped to launch its second New Glenn mission on November 9, but cancelled it last minute due to weather.

New Glenn's second mission is also notable because of its payload: The rocket ferried NASA satellites to space that are destined for Mars as part of the agency's ESCAPADE mission. Considering SpaceX's close relationship with NASA, Blue Origin working with the agency could be an important vote of confidence. 

It could also mean New Glenn is in a good position to help another company founded by Jeff Bezos accelerate its satellite plans. The Post writes that Blue Origin has an existing agreement with Amazon to launch its recently rebranded Amazon Leo satellites into space. Leo is positioned as a competitor to Starlink, SpaceX's satellite internet service.

While SpaceX has completed many more launches with its Starship rocket than Blue Origin has, it's also had more than a few explosive failures along the way. Blue Origin still needs more missions under its belt, but if it can repeat its success with New Glenn, it could prove to be a threat to SpaceX.

Blue Origin scrubs New Glenn’s second flight due to bad weather

Blue Origin has postponed the second flight of its New Glenn rocket, which was slated to send a pair of NASA spacecraft on the first step of their journey to Mars on Sunday afternoon. The heavy-lift launch vehicle was scheduled to take off from Cape Canaveral Space Force Station in Florida at 2:45PM ET., but multiple holds were issued during the under-two-hour launch window due to inclement weather. Blue Origin called off the launch attempt around 4:13PM.

The next launch opportunity is as yet unclear. Blue Origin was previously given a backup opportunity set for Monday afternoon, but the FAA has since issued an emergency order restricting commercial launches for the time being due to the government shutdown. As of November 10, commercial space launches can only take place between 10:00PM and 6:00AM. Blue Origin said on Sunday that it’s reviewing opportunities based on the weather, and did not mention the FAA’s order.

New Glenn's development has faced significant delays over the last decade since it was first announced, and finally took its maiden flight at the beginning of this year. Its first stage booster is intended to be reusable, and the company plans to recover the booster from the upcoming launch by landing it on an autonomous landing platform vessel dubbed Jacklyn, also known as the barge. Blue Origin attempted the same during its first flight, but failed. 

The spacecraft on board New Glenn are twin satellites built by Rocket Lab and operated by UC Berkeley for NASA's Escapade mission to study the effects of space weather. They'll be following a new trajectory to the red planet, lingering in "a lazy, 12-month kidney bean-shaped orbit" around Earth until Mars is in alignment, according to UC Berkeley. Escapade should reach Mars in 2027.

Blue Origin’s second New Glenn launch will carry real NASA satellites

Blue Origin has announced a target date for New Glenn’s second launch: November 9. This time, the mission will deploy real payloads, not just carry a technological demo for the company. Specifically, the spacecraft will be carrying the NASA Escapade mission’s twin satellites, which are headed to Mars. New Glenn, Blue Origin’s heavy-lift launch vehicle that was designed to be reused for a minimum of 25 flights, had its maiden flight in January. While the rocket made it to space, the company failed to land its first stage on its recovery ship in the Atlantic Ocean.

In a tweet, Blue Origin CEO Dave Limp said it won’t be a problem if it fails to stick the landing again. “We've got several more New Glenn boosters already in production,” he said. The mission’s primary goal, he clarified, is to get the Escapade satellites safely into orbit.

Mars missions typically launch during a narrow window of time when the red planet and the Earth are aligned. It’s a phenomenon that only happens once every two years. Colorado aerospace company Advanced Space designed Escapade’s trajectory for Mars missions that do not launch within that timeframe. The satellites will linger in the L2 Lagrange point between the sun and the Earth for a year. In November 2026, they will do a slingshot around our planet in order to reach Mars sometime in 2027 during that once-in-every-two-year alignment. “Can we launch to Mars when the planets are not aligned? Escapade is paving the way for that,” said Jeffrey Parker of Advanced Space.

New Glenn will lift off from Cape Canaveral Space Force Station’s Launch Complex 36. The company is aiming for a 2:45 PM Eastern time launch on November 9. As SpaceNews notes, the US government shutdown could limit NASA’s coverage, though the agency is still expected to livestream the event.

NASA’s supersonic jet completes its first flight in California

Nearly a decade after NASA partnered with Lockheed Martin to build the X-59, the supersonic jet has completed its first flight in California, according to a press release spotted by Gizmodo. The X-59 Quiet SuperSonic Technology (Quesst) aircraft is designed to reach supersonic speeds without the "sonic boom," and now with this latest test flight complete, NASA and Lockheed plan to conduct future tests to measure the X-59's "sound signature and conduct community acceptance testing."

The flight on Tuesday was between US Air Force Plant 42 in Palmdale, California and NASA's Armstrong Flight Research Center in Edwards, California. "The X-59 performed exactly as planned," Lockheed Martin says, "verifying initial flying qualities and air data performance on the way to a safe landing at its new home."

The ultimate goal for the X-59 project is to open up the possibility for commercial supersonic flights in the future. Traveling at supersonic speeds, faster than Mach 1 or around 768 miles per hour, could dramatically shorten trips transporting people and cargo. And if the Quesst design NASA and Lockheed Martin have come up with works, which includes tweaks like placing the jet engine on top of the plane and using an extremely pointy nose, it should also be much quieter. "People below would hear sonic 'thumps' rather than booms, if they hear anything at all," NASA explained in a 2023 blog post.

A ban on supersonic flights over the United States went into effect on April 27, 1973, in response to concerns of property damage and noise pollution. The ban stayed in place for decades until President Donald Trump ordered the Federal Aviation Administration to remove the ban in June 2025 as part of an executive order. Now there's a new urgency to NASA and Lockheed Martin's work with the X-59, and an opportunity to apply what they learn to "inform the establishment of new data-driven acceptable noise thresholds related to supersonic commercial flight over land."

Japan just sent the world’s first wooden satellite to space

Japanese researchers just sent the world’s first wooden satellite to space, as reported by CNN. LignoSat, named after the Latin word for wood, was developed by Kyoto University and a company called Sumitomo Forestry. It was included in a SpaceX mission to the International Space Station (ISS) and will soon be released into orbit above the Earth.

Why do this? There are two main reasons. First of all, it’ll be a test as to the durability of wood when faced with the harsh conditions of space. If successful, the researchers plan on making more wooden structures and jettisoning them to the cosmos.

A wood satellite.
Kyoto University

“With timber, a material we can produce by ourselves, we will be able to build houses, live and work in space forever,” said Takao Doi, an astronaut affiliated with Kyoto University. This is the first step in a 50-year plan that includes planting trees and building actual timber houses on the moon and even Mars.

“Early 1900s airplanes were made of wood,” said Kyoto University forest science professor Koji Murata. “A wooden satellite should be feasible, too.”

For those balking at the idea of wooden structures being used in space, consider some of the benefits. The material should actually be more durable in space than on Earth because, well, the endless void doesn’t have any water or oxygen. There’s nothing to cause rot and it's very hard for it to catch fire. It even offers fairly decent protection from radiation.

The other reason has to do with all of those other satellites in orbit. The planet’s currently surrounded by more than 3,000 satellites, not to mention all kinds of affiliated space debris. Wooden satellites would eventually fall back down to Earth and burn up during re-entry.

Metal satellites will (mostly) burn up during the return trip, but not before creating harmful aluminum oxide particles. We don’t really have a plan in place for the ever-expanding amount of space junk entombing the planet, so this could help. Doi envisions a scenario in which “metal satellites might be banned in the future.” In any event, having a log cabin on the moon would be one heck of a good time. There's literally an Apple TV+ show plus about just that
