Astronaut Mike Fincke finally reveals details of his medical emergency on ISS

9:33 am

Astronaut Mike Fincke, who had an undisclosed medical issue on ISS in January 2026 that forced the early return of his crew, has finally provided details of what happened.

Four-time space flier Mike Fincke said he was eating dinner on Jan. 7 after prepping for a spacewalk the next day when it happened. He couldn’t talk and remembers no pain, but his anxious crewmates jumped into action after seeing him in distress and requested help from flight surgeons on the ground. “It was completely out of the blue. It was just amazingly quick,” he said in an interview with The Associated Press from Houston’s Johnson Space Center.

Fincke, 59, a retired Air Force colonel, said the episode lasted roughly 20 minutes and he felt fine afterward. He said he still does. He never experienced anything like that before or since. Doctors have ruled out a heart attack and Fincke said he wasn’t choking, but everything else is still on the table and could be related to his 549 days of weightlessness. He was 5 ½ months into his latest space station stay when the problem struck like “a very, very fast lightning bolt.”

Fincke hopes he can fly in space again, but I doubt NASA would agree if the cause of this incident is not identified. His other option then would be to get hired by one of the commercial space station companies to fly to their stations, but even they might be reluctant to hire him.

Rocket Lab launches GPS-type demo satellite for Europe

9:05 am

Rocket Lab this morning successfully placed a European Space Agency (ESA) smallsat into orbit, its Electron rocket lifting off from one of its two launchpads in New Zealand.

The smallsat, dubbed Celeste, is the first of two such demo satellites that ESA has contracted Rocket Lab to launch. They are designed to test a low Earth orbit constellation for providing global navigation and location information to users on the ground, similar to the U.S.’s GPS constellation. Celeste will work from low orbit with Europe’s medium orbit Galileo constellation, but being smaller will be cheaper and faster to build and launch.

3 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

Neptune as seen by Voyager-2 in 1989, four days before closest approach

2:46 pm

Neptune as seen by Voyager-2 on approach
Click for original image.

Cool image time! In two earlier posts I highlighted the pictures taken by Voyager-2 of Neptune’s two largest moons, Triton and Proteus, when it made its close fly-by of Neptune in 1989. Other than a very distant low resolution picture of 105-mile-wide Nereid, Voyager-2 took no other good images of Neptune’s other known moons.

So today, let’s begin a tour of some of Voyager-2’s imagery of Neptune itself. The picture to the right, reduced slightly to post here, was taken on August 20, 1989 as the spacecraft was beginning its approach to Neptune. It shows the full daylight hemisphere of the gas giant. From the caption:

The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach. The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called Scooter and the little dark spot are visible. These clouds were seen to persist for as long as Voyager’s cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen.

Next week I will post some of the other good shots taken of Neptune, as well as one or two close-ups of Triton that need highlighting. Sadly, at that point we will have more or less reviewed most of the best data now available of this distant world. Astronomers have used the Hubble Space Telescope in subsequent years to attempt to track its weather patterns, but even Hubble really can’t provide enough resolution to really make that research substantive.

But stay tuned. The Voyager-2 images to come are worth viewing.

China launches “test satellite”

China yesterday afternoon successfully placed what its state-run press merely described as “a test satellite”, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.

That state-run press also provided no information as to where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

War Department conducts classified suborbital missile test from Cape Canaveral

9:16 am

The War Department yesterday launched an unidentified suborbital missile test from its Cape Canaveral Space Force Station in Florida, providing no public information about the rocket, the purpose of the launch, or who built it.

An unidentified missile launched and zoomed across the Atlantic Ocean Thursday, March 26, from Cape Canaveral Space Force Station, leaving a slim white contrail against the afternoon blue sky. None of the Space Coast’s major rocket-launch providers had missions scheduled on Thursday. The mysterious unannounced launch occurred at roughly 12:30 p.m.

The Pentagon did not respond to media requests for information.

The missile was likely a suborbital hypersonic test, but that is pure speculation. What makes it unusual is the lack of any information about launch provider. In recent years the military has relied entirely on the private sector to build its hypersonic test program. This launch suggests the War Department has moved from testing hypersonic components on private rockets, airplanes, and capsules to building and testing its own final hypersonic missile prototype.

This is also pure speculation. We will have to wait for some clarification from the Pentagon.

Ispace to replace engine on its lunar lander, delaying its NASA mission to 2030

9:09 am

Ispace's old and new landers

The Japanese lunar lander startup Ispace has been forced to institute a major shake-up of its upgraded lunar lander design because a subcontractor’s engine did not meet the required specifications.

The engine, called Voidrunner and built by Agile Space Industries, was about to be installed in the lander for a 2027 launch of NASA lunar lander mission when a review found its performance to be unsatisfactory.

After closely monitoring the engine’s status and conducting careful review, Ispace has determined that a change in the development plan to incorporate a new alternative engine is necessary to ensure the successful execution of the lunar landing mission. The new engine, which will replace VoidRunner, has already been developed by the alternative supplier and has a proven track record of operation in past lunar missions.

The company has also decided to standardize its two lunar lander designs, one developed in Japan and the second in parallel by its American division. The new lander, dubbed Ultra, will use this new engine and fly all of Ispace’s subsequent missions. The image above shows the company’s original lander Hakuto-R on the left, compared to its new Ultra lander on the right.

This change will delay its planned NASA mission by three years, to 2030, though the company hopes it will not impact the schedule of two other lunar lander missions for Japan. Its new updated schedule, all using Ultra:

  • 2028: a Japanese mission funded by Japan’s Ministry of Economy, Trade and Industry
  • 2029: a Japanese mission funded by Japan’s Space Strategy Fund (designed at encouraging the private space sector
  • 2030: NASA’s mission, being built in partnership with the American company Draper

Ispace has also created a new lunar satellite program, to provide communications, location data, and satellite tracking from lunar orbit, with a goal of launching its first lunar orbiter by next year, and five by 2030.

As a lunar lander company Ispace has had a very mixed record. It has successfully flown two landers to lunar orbit and then down to the surface. Each however crashed, failing just prior to landing due to software issues. This new delay of its NASA mission is not going to please NASA administrator Jared Isaacman, who instead wants to speed up the agency’s lunar lander program, flying almost monthly beginning in 2030. It likely means Ispace is going to have problems winning any new NASA lander contracts, until it proves its new Ultra lander design.

Proteus, Neptune’s second largest moon, discovered by Voyager-2 in 1989

3:02 pm

Proteus, Neptune's second largest moon
For original images go here and here.

Our tour continues of the only close visit to Neptune on August 25, 1989 by Voyager-2. The two pictures to the right were taken by the spacecraft during that fly-by of Neptune’s second largest moon, dubbed Proteus. Both pictures are shown as Voyager-2 took them.

The top picture was taken from a distance of about 540,000 miles, and has a resolution of about five miles per pixel.

The satellite has an average radius of about 120 miles and is uniformly dark with an albedo of about 6 percent. The irregular shape suggests that 1989N1 has been cold and rigid throughout its history and subject to significant impact cratering.

The bottom picture was taken from a distance of about 91,000 miles, and can resolve objects as small as 1.7 miles in size.

Hints of crater-like forms and groove-like lineations can be discerned. The apparent graininess of the image is caused by the short exposure necessary to avoid significant smear.

Proteus was not known prior to Voyager-2’s fly-by, because it orbits so close to Neptune (about 73,000 miles) that the ground-based telescopes of the time could not see it in the glare of the gas giant. It was discovered in early global pictures of Neptune as Voyager-2 approached.

While planetary scientists have made some educated guesses about the moon’s origin and geology based on these two images, they are simply guesses. These are the only detailed images we have of Proteus, and neither is particularly good.

Astronomers detect the first comet whose nucleus’ reversed its rotation

11:28 am

Astronomers using data collected by the orbiting Gehrels Swift and Hubble space telescopes now think the nucleus of a small comet reversed its rotation sometime in 2017, caused by the force of the material sublimated off its surface.

From the abstract of their paper [pdf]:

The rotations of cometary nuclei are known to change in response to outgassing torques. The nucleus of the Jupiter-family comet 41P/Tuttle–Giacobini–Kresak exhibited particularly dramatic rotational changes when near perihelion in 2017 April. Here, we use archival Hubble Space Telescope observations from 2017 December to study the postperihelion lightcurve of the nucleus and to assess the nucleus size.

From both Hubble photometry and nongravitational acceleration measurements, we find a diminutive nucleus with effective radius 500 ± 100 meters. Systematic optical variations are consistent with a two-peaked (i.e., rotationally symmetric) lightcurve with period 0.60 ± 0.01 days, substantially different from periods measured earlier in 2017. The spin of the nucleus likely reversed between perihelion in 2017 April and December as a result of the outgassing torque.

In plain English: the thrust of the material being thrown from the surface as the comet made its close approach to the Sun was sufficient to slow and then reverse the nucleus’s rotation. This process was helped by the relatively small size of the nucleus compared to the material being sublimated from it.

The data also suggests the nucleus was once much larger, and has been whittled down to its present small size as it made its multiple close fly-bys of the Sun during the past 1,500 years. Rather than break-up, as most comets do at some point as their nucleus gets smaller, this comet’s nucleus simply kept shrinking, to the point that the thrust of that material could change its rotation.

The space station part of Isaacman’s new program is facing push back, from industry and Congress

10:37 am

The American space stations under construction
Four of the American space stations under development.
The fifth, Max Space, is a late comer and not shown.

At a hearing yesterday before the space subcommittee of the House Science, Space, and Technology Committee, both the trade organization representing the five commercial space station projects as well as some members of Congress expressed strong reservations about NASA’s new plan to build a core module as a basis for helping these companies develop their space stations.

Dave Cavossa, President of the Commercial Space Federation (CSF) that represents these companies, outlined in his statement [pdf] to the committee the industry’s dissatisfaction, not so much because of the specifics of NASA’s plan but because it follows other sudden changes last year by the previous NASA administrator Sean Duffy, and is still uncertain in its outline.

Given the delays and possible shifts in strategy, industry has been left to continue spending resources to develop private space stations without a full understanding of what NASA will require from a private station, how the agency will structure the rest of the procurement and program, and when industry may see a return on investment. This uncertainty challenges the public-private partnership business model and puts the agency at risk of deorbiting ISS before private stations are operational.

The trade group proposed that NASA stick with its previous plan to fund two or more station projects, dropping Isaacman’s core module proposal. It also wanted Congress give the agency the funds to do so.

Cavossa also strongly disputed NASA’s claim that the market at present doesn’t support these commercial stations.

All space stocks soar in anticipation of SpaceX’s impending IPO

9:51 am

It appears SpaceX’s upcoming initial public offering (IPO) of publicly-traded stocks, now anticipated to raise as much as $75 billion for the company, has caused stock investors to also pour their money into a whole range of space stocks, causing them all to soar in value.

Initially, it was expected that the IPO could raise $50 billion for the company, but the latest report indicates it could raise as much as $75 billion, with a valuation as high as $1.75 trillion. The colossal figures being thrown around on Wednesday have garnered excitement among investors for other space stocks that are already publicly traded.

Here were the top gainers in the session:

  • Firefly Aerospace: +19%
  • Intuitive Machines: +11%
  • AST SpaceMobile: +9%
  • EchoStar Corporation: 9%
  • Rocket Lab Corporation: +8%

The most recent indications suggest SpaceX will file the offering’s prospectus in the next week or so. If the predictions about it are correct, and SpaceX does raise $75 billion, it would then have on hand more than three times the cash that Congress normally budgets annually to NASA, with an ability to use that money far more effectively.

As I have been saying now for more than a year, the real space program for the United States is being run by SpaceX, not NASA. Expect SpaceX to outpace NASA in their parallel and complementary efforts to build a moonbase.

Webb and Hubble take a look at Saturn

9:37 am

Saturn seen by Webb and Hubble

Astronomers using both the Hubble Space Telescope and the Webb Space Telescope have produced new complementary views of the ringed planet Saturn.

Those photographs are shown above, with Webb’s false-color infrared image to the left and Hubble’s optical image to the right. From the press release:

In the Webb image, a long-lived jet stream known as the “ribbon wave” meanders across the northern mid-latitudes, influenced by otherwise undetectable atmospheric waves. Just below that, a small spot represents a lingering remnant from the “Great Springtime Storm” of 2010 to 2012. Several other storms dotting the southern hemisphere of Saturn are visible in Webb’s image, as well. All these features are shaped by powerful winds and waves beneath the visible cloud deck, making Saturn a natural laboratory for studying fluid dynamics under extreme conditions.

…In Webb’s infrared image, the rings are extremely bright because they are made of highly reflective water ice. In both images, we’re seeing the sunlit face of the rings, a little less so in the Hubble image, hence the shadows visible underneath on the planet.

There are also subtle ring features such as spokes and structure in the B ring (the thick central region of the rings) that appear differently between the two observatories. The F ring, the outermost ring, looks thin and crisp in the Webb image, while it only slightly glows in the Hubble image.

The press release says little about the Hubble image, mostly because it shows little new by itself. It however is part of an on-going decade-long survey using Hubble to track Saturn’s changing weather patterns.

While both images are valuable, they also highlight our present limits in observing Saturn. Views from Earth can only see so much. It is like trying to watch a football game from ten miles away, with binoculars. And sadly, no mission is presently planned to return to Saturn.

Isar’s second launch attempt scrubbed due to abort at T-0 seconds

1:35 pm

Proposed or active spaceports in North Europe
Proposed or active spaceports in North Europe

The German rocket startup Isar Aerospace was today forced to scrub its second attempt to launch its Spectrum rocket from Norway’s Andoya spaceport when the rocket aborted the launch at T-0 seconds.

The launch was then scrubbed for the day because the launch window was only 15 minutes long. An earlier hold due to a boat violating the range had used up most of the window, leaving no time to recycle the rocket to try again.

No word yet on when the company will try again. At the moment Isar is in the lead to be the first new European startup to get off the ground, though Rocket Factory Augsburg from Germany and PLD from Spain are not far behind. Isar’s first launch attempt in March 2025 had failed seconds after lift-off due to a loss of attitude control.

Andoya is also in the lead to be the first European spaceport to complete an orbital launch, though SaxaVord on the Shetland Islands hopes to see that Rocket Factory launch in the coming months.

Triton: Neptune’s largest moon

11:19 am

The southern mid-latitudes of Neptune's moon Trident
Click for original image.

Triton

Today’s cool image begins a new tour I plan on doing over the next week or so of the few close-up photographs we have of Neptune and its moons, sent back by Voyager-2 when it did its close fly-by of this distant planet on August 25, 1989. That fly-by was almost 37 years ago, and it remains our only close look. While at the time it shined a quick flashlight of new knowledge on Neptune, its moons, and its ring system, we remain generally in the dark about what’s there, despite some good imagery produced in subsequent years by Hubble and some ground-based telescopes.

The image above, cropped and enhanced to post here, shows a portion of the southern mid-latitudes of Triton, Neptune’s largest moon, as Voyager-2 made its closest pass at a distance of about 25,000 miles. The photo to the right, cropped and reduced, shows a more global view to provide some context, with the box indicating the approximate area covered by the upper image. It was taken when Voyager-2 was on approach, at a distance of about 330,000 miles. The top picture captures several dozen black plumes that appear to vent material from below. From the caption:

The plumes originate at very dark spots generally a few miles in diameter and some are more than 100 miles long. The spots which clearly mark the source of the dark material may be vents where gas has erupted from beneath the surface and carried dark particles into Triton’s nitrogen atmosphere. Southwesterly winds then transported the erupted particles, which formed gradually thinning deposits to the northeast of most vents.

It is possible that the eruptions have been driven by seasonal heating of very shallow subsurface deposits of volatiles, and the winds transporting particles similarly may be seasonal winds. The polar terrain, upon which the dark streaks have been deposited, is a region of bright materials mottled with irregular, somewhat dark patches. The pattern of irregular patches suggests that they may correspond to lag deposits of moderately dark material that cap the bright ice over the polar terrain.

As we only have a few images of this planet, and those provided views of only about 40% of its surface, any theory that tries to explain the weird geology here is certain to be wrong to some degree.

More to come in the next few days. As much as we think we know, these pictures are going instead highlight how sparse that knowledge really is.

Swiss orbital tug startup Pave Space raises $40 million

9:03 am

A new orbital tug startup from Switzerland, Pave Space, has now successfully raised $40 million in private investment capital that it will use to develop a new kickstage engine and fly it on a demo mission.

The funding round was led by Visionaries Club and Creandum, with participation from Lombard Odier Investment Managers, Atlantic Labs, Sistafund, b2venture, ACE Investment Partners, Ilavaska Vuillermoz Capital, Pareto & Motier Ventures.

Pave had its start as a student project that built a reusable small hopper to test vertical take-off and landing. The company now joins about a dozen other orbital tug companies, offering a range of serves from moving satellites to removing space junk to doing satellite repair. Based on the amount of money that all of these companies are raising, both in the U.S. and Europe, it appears the investment community sees a strong demand for these services down the road, especially with the many gigantic constellations being proposed.

Intuitive Machines wins $180.4 million new NASA lunar lander contract

8:46 am

Intuitive Machines' Nova-D lunar lander
Click for original.

The lunar lander startup Intuitive Machines announced yesterday that it has won its fifth contract from NASA, a $180.4 million deal to place its larger upgraded Nova-D lander near the Moon’s south pole.

The IM-5 mission will target Mons Malapert, a ridge near the Lunar South Pole that offers continuous Earth visibility, stable illumination conditions, and access to permanently shadowed regions. These characteristics make the site a compelling location for future communications, navigation, and surface infrastructure.

The artist’s rendering to the right shows this Nova-D lander. What stands out immediately is its low-slung appearance. Intuitive Machines’ smaller Nova-C lander was tall (see this image), with a high center of gravity. In its only two landing attempts on the Moon it tipped over both times after touchdown. It appears the company has finally recognized the issue and reworked this new lander to make it more stable after touchdown.

This contract award appears to be part of the accelerated program by NASA administrator Jared Isaacman to land 30 unmanned rovers on the moon in three years, beginning in 2027. Mons Malapert is a plateau that Intuitive Machines second lander tipped over on. It is also the landing site for Astrobotics’ Griffin lander, as well as a candidate landing site for the first Artemis manned missions.

Note the small rover on the right in the graphic. While the mission will carry seven NASA science instrument payloads, it will also carry this commercial rover, built by Honeybee Robotics, a subsidiary of Blue Origin. As the company states above, the lander on this mission also has additional available payload capacity for more commercial customers.

Lunar Gateway dead as NASA announces major changes to its future space station, lunar, and Mars plans

1:07 pm

Capitalism in space As part of the reshaping of NASA being pushed by NASA administrator Jared Isaacman, the agency today announced major changes to its future programs in low Earth orbit, on the Moon, and in exploring Mars. Video of these changes can be viewed here and here.

The Moon

NASA will now focus all work in its lunar program on getting to the surface of the Moon. Lunar Gateway is “paused,” though the language of NASA’s press release suggests more strongly that it is dead, with the agency already trying to figure out ways to “repurpose” its already built components. NASA will instead ask for proposals from private industry and its international Artemis partners to ramp up as soon as possible a phased program to establish the infrastructure on the Moon needed for the lunar base. This new focus begins with “up to 30 robotic landings in three years, starting in 2027,” and at least two manned landings per year beginning in 2028.

The graph below, presented during today’s announcement, shows the basic plan for the next few Artemis missions, which will act as the manned foundation for this entire surface-focused program. The overall program will build out the lunar base in three phases, first to test some basic infrastructure using these smaller lunar landers, second to begin establishing the base’s foundational components with intermittent manned missions, and third to begin long-term human occupancy.
