NASA unwittingly reveals its bankruptcy by its reliance on AI

Uranus as seen by Hubble in 2014 and 2022
Click for original image.

In what appeared to be a totally inexplicable press release today, NASA posted the two pictures of Uranus to the right. The accompanying text was truly puzzling, describing in a somewhat brainless and inaccurate manner what is in the pictures;

Two views of the planet Uranus appear side-by-side for comparison. At the top, left corner of the left image is a two-line label. The top line reads Uranus November 9, 2014. The bottoms line reads HST WFC3/UVIS. At the top, left corner of the right image is the label November 9, 2022. At the left, bottom corner of each image is a small, horizontal, white line. In both panels, over this line is the value 25,400 miles. Below the line is the value 40,800 kilometers. At the top, right corner of the right image are three, colored labels representing the color filters used to make these pictures. Located on three separate lines, these are F467M in blue, F547M in green, and F485M in red. On the bottom, right corner of the right image are compass arrows showing north toward the top and east toward the left. [emphasis mine]

First, the description doesn’t match the pictures precisely, as if whoever wrote it wasn’t looking at these pictures. Second, the description is ridiculously literal, and really provides no information at all. (Consider for example the highlighted sentence. All it is doing is describing a standard scale bar, in the strangest most stupid manner possible.)

I immediately surmised that someone at NASA has decided to use AI to do this work, and AI (in its typical stupid brilliance) provided this worthless text. The unnamed NASA employee — equally as stupid — then posted it without reading it, assuming AI had done his or her job perfectly.

What makes this display of stupidity even worse is that these pictures, and a real press release, were issued back in 2023, when I posted these pictures initially. Does no one at NASA ever bother to read their own press releases?

Apparently not. The advent of AI has now produced human employees at the space agency who read nothing, know nothing, and do nothing. They instead plug stuff into AI and pump it out to the public mindlessly.

No wonder Trump wants to slash NASA’s budget. We certainly ain’t getting our money’s worth from the people that are there.

I also fully expect NASA management to soon deep-six this press release, or to fix it quickly once they read this post.

Senate schedules vote for confirming Jared Isaacman as NASA administrator

2:48 pm

The Senate is now targeting early June for its vote on Jared Isaacman’s nomination as NASA administrator.

Senate Majority Leader John Thune (R-S.D.) filed cloture on Isaacman’s nomination May 22, a procedural move that would set up a vote on the nomination in early June. The Senate is not in session the week of May 26 because of the Memorial Day holiday.

Since his nomination was approved by the Senate Commerce committee in April, Isaacman has been meeting with many other senators. The article at the link does the typical mainstream press thing of pushing back 100% against the proposed NASA cuts put forth by Trump’s 2026 budget proposal, telling us that these senators were generally opposed to those cuts and questioning Isaacman about them, a claim not yet confirmed. It did note something about those senators and those proposed cuts that if true was very startling and possibly very encouraging.

While many of the proposals in the budget, like winding down SLS and Orion, were expected, the scale of the cuts, including a nearly 25% overall reduction in NASA spending, still took many by surprise. [emphasis mine]

In other words, Congress was not surprised by the proposed end of SLS and Orion. It even appears they are ready to give it their stamp of approval.

None of this is confirmed, so take my speculation with a grain of salt. Still, the winds do appear to be blowing against SLS and Orion.

Cargo Dragon undocks from ISS

2:55 pm

That this story is not news anymore is really the story. A cargo Dragon capsule that has been docked to ISS since April 22, 2025 today undocked successfully and is scheduled to splashdown off the coast of California on Sunday, May 25, 2025 in the early morning hours.

SpaceX’s Dragon missions to ISS have become so routine that NASA is not even planning to live stream the splashdown, posting updates instead online. This is not actually a surprise, since NASA has practically nothing to do with the splashdown. Once the capsule undocked from ISS, its operation and recovery is entirely in the hands of SpaceX, a private American company.

For NASA, SpaceX is acting as its UPS delivery truck, bringing back to several tons of experiments. And like all UPS delivery trucks, making a delivery is not considered news.

And yet, this is a private commercial spacecraft returning from space, after completing a profitable flight for its owners! That this is now considered so routine that it doesn’t merit much press coverage tells us that the industry of space is beginning to mature into something truly real and sustainable, irrelevant to government.

More missions to Apophis when it flies past Earth in 2029?

11:45 am

Apophis' path past the Earth in 2029
A cartoon (not to scale) showing Apophis’s
path in 2029

There were two stories today that heralded the addition of one real and two potential new spacecraft to rendezvous with the potentially dangerous asteroid Apophis when it flies past the Earth on April 13, 2029.

First, the European Space Agency (ESA) awarded a 1.5 million euro contract to the Spanish company Emxys to build a small cubesat that will fly on ESA’s Ramses mission to Apophis. This is the second cubesat now to fly attached to Ramses, with the first designed to use radar to study Apophis’ interior.

The second CubeSat, led by Emxys, will be deployed from the main spacecraft just a few kilometres from Apophis. It will study the asteroid’s shape and geological properties and will carry out an autonomous approach manoeuvre before attempting to land on the surface. If the landing is successful, it will also measure the asteroid’s seismic activity.

Second, American planetary scientists have been lobbying NASA to repurpose the two small Janus spacecraft for a mission to Apophis. These probes were originally built to go to an asteroid as a secondary payload when the Pysche asteroid mission was launched, but when Pysche was delayed they could no longer go that that asteroid on the new launch date. Since then both Janus spacecraft have been in storage, with no place to go.

The scientists say they could easily be repurposed to go to Apophis, but NASA will have to commit to spending the cost for launch, approximately $100 million. NASA officials were not hostile to this idea, but they were also non-committal. I suspect no decision can be made until the new administrator, Jared Isaacman, is confirmed by the Senate and takes office.

Time however is a factor. The longer it takes to make a decision the fewer options there will be to get it to Apophis on time.

At the moment there is only one spacecraft in space and on its way to Apophis, and that is the repurposed Osiris-Rex mission, now called Osiris-Apex. Japan might also send a craft past Apophis as part of its mission to another asteroid.

Learning as much as we can about Apophis is critical, as there is a chance it will impact the Earth sometime in the next two hundred years.

Space station startup Voyager Technologies about to go public

10:52 am

Starlab design in 2025

for original image.

The space station startup Voyager Technologies (formerly Voyager Space) has filed its paperwork for its expected initial public offering (IPO) of stock as it competes for a major contract from NASA to build its Starlab space station.

Voyager filed a preliminary prospectus for its planned initial public offering (IPO) with the U.S. Securities and Exchange Commission May 16. The company previously confidentially filed plans for its IPO with the SEC. The draft prospectus does not yet disclose how many shares the company plans to sell or the amount the company expects to raise in the IPO. It does, though, offer financial details about Voyager.

The company reported $144.2 million in revenue in 2024 and a net loss of $65.6 million, versus $136.1 million in revenue and a net loss of $25.2 million in 2023. The company also reported revenue of $34.5 million in the first quarter of 2025, and a net loss of $27.9 million.

This story actually made me less confident about this company’s plans, with this quote the most revealing:

The company received a funded Space Act Agreement from NASA to support initial design work on the station, currently worth $217.5 million with $70.3 million yet to be paid. … The NASA award covers only initial work on Starlab, and the company will have to compete for a second phase of NASA’s Commercial Low Earth Orbit Development program that will offer additional funding for station development. Voyager revealed in the prospectus that it projects Starlab to cost $2.8 billion to $3.3 billion to develop.

So far it appears Voyager has built nothing. Instead it has used NASA’s preliminary money to do and redo its on-paper design of Starlab (compare the more recent design concept in the image on the right with this older image from 2022), which as a concept is intended to be launched whole on a single Starship launch. No metal has been cut. The company appears to be following the old big space company approach of investing nothing of its own in development.

This does not mean its station will be a failure, but I expect it will not launch as scheduled in 2029 if it wins that major NASA contract. The company will have to build it all in less than three years, something that I doubt it will be able to do.

My present rankings for the four proposed commercial stations:

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for an estimated 30 days total. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth scheduled for early June, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreement with the European Space Agency. It recently had its station design approved by NASA, but it has built nothing, and appears unwilling to cut any metal until it wins NASA’s full contract.

Axiom’s next commercial manned flight to ISS delayed at least one week

9:06 am

NASA and Axiom have delayed the launch of the company’s fourth commercial manned flight to ISS by at least a week, from May 29 to June 8, at the earliest.

The NASA press announcement was decidedly vague about the reason:

After reviewing the International Space Station flight schedule, NASA and its partners are shifting launch opportunities for several upcoming missions. The schedule adjustments provide more time to finalize mission plans, spacecraft readiness, and logistics.

This report speculates that SpaceX might have had additional issues getting its brand new manned Dragon capsule ready on time, without out any clear evidence. The capsule has taken longer to build than originally predicted, but giving SpaceX one extra week seems insufficient if the capsule had some outstanding technical issues.

More likely it is exactly as NASA states, the delay is to accommodate the complex coming and going of vehicles to ISS.

The mission will launch one Axiom command pilot and three passengers, government astronauts from India, Poland, and Hungary.

This new manned Dragon, as yet unnamed, will bring SpaceX’s fleet of manned capsules to five, assuming it does not retire one of the older capsules. The company will thus have the largest manned spacecraft fleet ever, exceeding NASA’s four shuttle fleet that existed in the 1990s.

NASA engineers end second super pressure balloon flight early

9:23 am

Flight path of second super pressure balloon test
Flight path of second super pressure balloon test

Due to an issue with its power system, NASA engineers today decided to end its second super pressure balloon flight this year after only nine days, when the balloon crossed over South America and thus allowing them to recover it safely.

Although the balloon performed well and the mission successfully met its minimum requirements toward qualification of the balloon system, an issue with the power system aboard the balloon gondola prompted the team to terminate the mission early as a precaution. The team had been monitoring a power failure in one of the redundant charging systems since May 8.  “Despite the loss of one of the redundant charging systems, the remaining power system was performing very well and still able to sustain the batteries and electrical equipment over the course of the mission,” said Hamilton. “However, to be cautious, the team opted to end the flight early to get the equipment back, so we can do a full failure analysis.” 

After identifying a safe area and coordinating with Argentinian officials, the flight was safely terminated. Recovery of the balloon and payload is in progress. 

The first flight flew for seventeen days, circling the globe at the high southern latitudes. In that case issues with the balloon caused the flight to be terminated while it was over the ocean, preventing recovery. As the goal with both flights was to fly for 100 days, neither came close to that target.

Academics in space community scheme to continue their racist DEI policies

1:41 pm

USRA logo

A letter sent out yesterday by the Universities Space Research Association (USRA) clearly illustrated the bigoted desire of our modern Marxist academic community to continue its racist Diversity, Equity, and Inclusion (DEI) policies in hiring by hiding or renaming them so that the Trump administration might not notice.

USRA is one of several university consortiums that manage a variety of space, science, and astronomical operations for the government. In USRA’s case, it manages the Lunar Planetary Institute (LPI) for NASA.

The letter purported to announce how the organization was complying with Trump’s executive orders banning such race-based programs, but instead revealed its desire to continue them, but to do so under the table where no one could monitor them.

Update on Vast’s space station plans

10:19 am

Haven-2
Haven-2 station once completed

Link here. The article provides a very detailed look at Vast’s short and long range plans, including its overall strategy to win NASA’s full space station construction contract by first building, launching, and occupying its small scale Haven-1 station and thus demonstrating it is the right company for NASA to finance its full scale Haven-2 rotating space station (shown in the graphic to the right).

The article notes that Vast intends to complete Haven-1’s primary structure in July, and do environmental and vibration ground testing from January to March 2026, with its planned launch on a Falcon 9 rocket in May 2026. Once launched it plans to put crews on board for a total of 30-days (though it is unclear at this moment whether that will be a single mission or a series of shorter flights).

In addition, the article reveals that the company also hopes to do two spin tests of Haven-1, testing its ability to rotate and create an artificial gravity. That aligns with the goal of Vast’s full scale Haven-2 station, which it wants to rotate as well. Since the plan is to assembly Haven-2 from upgraded Haven-1 modules, these spin tests are essential for proving the larger station’s design.

Based on this new information, I think we can now map out the evolving but still subject-to-change manned operations at Haven-1, comprising several short 3-5 day manned missions. The first will the crew test the module’s operation. The next two will be to do these spin tests, with people on board.

Vast’s strategy is fundamentally different than the other proposed stations (all listed below). Instead of taking a small NASA development grant to create designs on paper, it is spending its own money to actually launch a demonstration station. If successful, this strategy will make it very easy for NASA to pick it when the time comes to award the larger station construction contracts.

My present rankings for the four proposed commercial stations:

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for an estimated 30 days total. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth scheduled for early June, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreement with the European Space Agency. It recently had its station design approved by NASA.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.

NASA cancels VIPER solicitation

9:06 am

NASA today announced that it has canceled its solicitation from the private sector, asking for proposals for launching its overbudget and as yet unfinished lunar rover VIPER to the Moon.

NASA announced Wednesday it is canceling its Lunar Volatiles Science Partnership Announcement for Partnership Proposals solicitation, which sought opportunities to send VIPER to the Moon at no cost to the government.

The announcement, which was very short and lacking in any details, stated also that the agency “will announce a new strategy for VIPER in the future.”

Some background: VIPER was originally budgeted at $250 million. When cancelled in 2024 its budget had ballooned to over $600 million, and that wasn’t enough to complete the rover for launch.

This decision suggests the agency did not get any worthwhile proposals. Apparently, no one was interested in paying the cost to get VIPER finished (about $100 million) and launched. It is also likely that the planned Trump budget cuts had an impact on this decision. NASA management probably recognized that there was no way they could con the administration into forking over any money to finance any private proposal.

It is also possible that this cancellation now is part of the typical game NASA managers always play to get Congress to fund bloated programs like this. Cancel it, get the propaganda press to cry about how the cancellation is so terrible, which in turn gets Congress outraged and willing to approve the extra funds.

ESA’s issues a non-reaction to Trump’s proposed NASA cuts

9:23 am

The European Space Agency (ESA) yesterday issued its first reaction to Trump’s proposed cuts to NASA’s Artemis program, including cancellation of the Orion capsule and Lunar Gateway station that ESA is building major components, and essentially said nothing.

NASA has briefed ESA about the Budget Request, and while some questions still remain about the full repercussions, follow-up meetings are already taking place with NASA. ESA remains open to cooperation with NASA on the programmes earmarked for a reduction or termination but is nevertheless assessing the impact with our Member States in preparation for ESA’s June Council.

ESA and NASA have a long history of successful partnership, particularly in exploration – a highly visible example of international cooperation – where we have many joint activities forging decades of strong bonds between American and European colleagues. Space exploration is an endeavour in which the collective can reach much farther than the individual. Thus, ESA has strong partnerships with space agencies from around the globe and is committed to not only being a reliable partner, but a strong and desirable partner.

Basically ESA is holding off any major response until they get more information from NASA and the Trump administration. It also notes that any more detailed response must wait until it holds its own meetings scheduled for June and later.

ESA’s problem is that it tied its manned space effort to NASA’s Orion capsule and Gateway station. On Orion it is building the service module, and has a number under construction that now might be unneeded if only two more Orions fly. As for Gateway, Europe is building major components of the station’s central habitation module. It is also building, in partnership with Japan, a second habitation module for their use. The cancellation of Gateway leaves these modules hanging with nowhere to go.

Though we should expect some pushback from Europe in an attempt to save Lunar Gateway, I expect these events will end up doing more for Europe’s nascent commercial launch industry. What the continent really needs is a private competitive aerospace industry making money in space. If it gets that, it will no longer have to rely on NASA, or ESA for that matter.

And based on the recent policy actions by ESA’s major partners (Germany, France, Italy, Spain, and the UK) to shift from a government-run centralized space program run by ESA’s Arianespace to encouraging the development of an independent competing private launch industry, I predict Europe will shift even more focus in this direction when they finally respond to the Trump cuts.

Expect European to call for more autonomy and European-built rockets and spacecrafts that do not rely on NASA or American proposals. This will not necessarily end its space partnership with the U.S., but it will be less beholden to it.

NASA engineers complete 17-day balloon flight, testing a new “super pressure” technology

8:54 am

Map of flight
Click for original map

NASA engineers have decided to end a flight test of a new “super pressure” balloon after flying for seventeen days and circling Antarctica.

While the mission successfully met its minimum requirements for qualification of the balloon, the team had been monitoring minor performance issues and suspected that the system had a small leak. The balloon was maintaining its predicted float altitude during daytime hours; however, it started to show considerable drops in altitude, especially as it passed through areas of colder temperatures like storm systems.

…Teams continued to closely monitor the health and performance of the balloon as it continued flight, and its ability to safely make it to the next predicted land crossing in South America for recovery of the balloon and payload. However, at approximately four additional days until land, all ballast expended to manage altitude stability, and recent altitude excursions during night periods down to 60,000 feet, continued flight became unlikely. NASA ultimately decided to terminate the flight to ensure the greatest level of control and safety during descent. “Due to the mission’s trajectory coupled with system performance, termination and recovery at the next land over flight was not possible due to unacceptable public risk,” said Garde.

This first flight is part of a two-flight test program this season, with the second super pressure balloon already in flight. Like the first, it is aiming for a 100 day flight circling the globe at the high mid-latitudes comparable to its launch site in New Zealand. You can track its flight in real time here.

As with all NASA test programs like this, the real question will be whether this technology will be used for any practical purpose once the program is completed, or whether it will be shelved away and forgotten. For most such programs, it is the latter that occurs. In this case however there are a number of companies attempting to make money selling tourists flights on less sophisticated high altitude balloons, and those companies might be interested in adopting this technology. There are also several balloon companies that provide surveillance data for the military which might be interested as well.

It only took $22 billion and 19 years: Lockheed Martin proudly announces the completion of the first Orion capsule capable of manned flight

10:56 am

Orion's damage heat shield
Damage to Orion’s heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”.
Nor has this issue been fixed.

My heart be still. On May 1, 2025 Lockheed Martin proudly announced that it had finally completed assembly and testing of the first Orion capsule capable of taking human beings into space.

Lockheed Martin [NYSE: LMT] has completed assembly and testing of NASA’s Orion Artemis II spacecraft, transferring possession to NASA’s Exploration Ground Systems (EGS) team today. This milestone is a significant step for NASA and the Artemis industry team, as they prepare to launch a crew of four astronauts to further the agency’s mission in establishing a human presence on the Moon for exploration and scientific discovery. It will also help build the foundation for the first crewed missions to Mars.

Orion is the most advanced, human-rated, deep space spacecraft ever developed. Lockheed Martin is the prime contractor to NASA for Orion and built the crew module, crew module adaptor and launch abort system. “This achievement is a testament to our employees and suppliers who have worked tirelessly to get us to this important milestone,” said Kirk Shireman, vice president of Human Space Exploration and Orion program manager at Lockheed Martin. “The Orion spacecraft completion for Artemis II is a major step forward in our nation’s efforts to develop a long-term lunar presence. It’s exciting to think that soon, humans will see the Earth rise over the lunar horizon from our vehicle, while also traveling farther from Earth than ever before.”

What disgusting hogwash. First of all, Lockheed Martin was issued the contract to build two capsules, one for testing and one for manned flight, in 2006. It only took the company 19 years to build both. Second, that 2006 contract was supposed to only cost $3.9 billion. Instead, NASA has forked out more than $22 billion.

And what have we gotten? Two capsules, plus a handful of prototype test versions. Worse, this first capsule will be the first to ever carry the life support systems that keep humans alive, as Lockheed Martin admits in its press release:

Trump administration releases its proposed NASA budget for 2026

10:29 am

The Trump administration today released [pdf] its proposed federal budget for the 2026 fiscal year, calling for an overall reduction in federal spending by about 7.6%, with NASA getting a budget cut of about 24%.

A summary of the budget can be found in this NASA press release. The main bullet points are these:

  • SLS and Orion will be retired after flying the two more missions. Whether those flights will be manned or not however is left vague.
  • Lunar Gateway will be shut down
  • The Mars Sample Return mission will be cancelled.
  • The overall manned budget for interplanetary development is increased, and now includes a line item of $1 billion for “Mars-focused programs”.
  • Flights to ISS are reduced (cutting a half billion from this budget) to facilitate the “transition to a more cost-effective commercial approach to human activities in space as the space station approaches the end of its life cycle.”
  • Eliminates “low-priority climate monitoring satellites”, shifting the focus to getting such data from commercial sources.
  • Major budget cuts are proposed for many other departments, and also include a major restructuring of NASA’s entire operation to “streamline the workforce, IT services, NASA Center operations, facility maintenance, and construction and environmental compliance activities.”

Below is a screen capture from the budget proposal detailing these cuts.

Psyche asteroid probe experiences an unexplained engine problem

12:36 pm

Psyche's flight path to the asteroid Psyche
Psyche’s flight path to the asteroid Psyche.
Click for original image.

The probe Psyche, presently on its way to the asteroid of the same name, has experienced a thruster issue with its electric ion-type main engine that has forced engineers to postpone further engine use as they troubleshoot the problem.

Psyche began firing its thrusters in May 2024. On April 1, the spacecraft detected a pressure drop in the line that feeds the xenon gas to the thrusters, going from 36 pounds per square inch (psi) to about 26 psi. As designed, the orbiter powered off the thrusters in response to the decrease.

The mission team has chosen to defer thrusting while engineers work to understand the pressure decrease. The mission design supports a pause in thrusting until at least mid-June before the spacecraft would see an effect on its trajectory. The electric propulsion system has two identical fuel lines, and the team may decide to switch to the backup fuel line to resume thrusting.

This mission has been plagued with problems. First its software was completed late, forcing a year delay in its launch. Next it was discovered — too late to fix — that transistors on the spacecraft had not been properly hardened for the hostile environment of space. Engineers hope these transistors “will heal themselves” once in that environment, but there are no guarantees. [My memory is becoming fuzzy. As many of my readers pointed out, this transistor problem was with Europa Clipper, not Psyche.]

Now its electric ion engine, essential to getting it to Psyche, is not working properly.

If this problem is fixed and Pysche resumes engine firing, it is targeting an arrival at the asteroid Psyche in 2029.

Jared Isaacman’s nomination approved by Senate committee

12:24 pm

The Senate Commerce, Science, and Transportation Committee today voted 19 to 9 in favor of Jared Isaacman, Trump’s nominee to become NASA administrator.

The vote was 19-9, with all Republicans and four Democrats voting yes and nine Democrats voting no. The four Democratic yes votes were Senators Maria Cantwell (Washington), Tammy Baldwin (Wisconsin), John Hickenlooper (Colorado) and Andy Kim (New Jersey).

The nine Democratic no votes were Senators Amy Klobuchar (Minnesota), Brian Schatz (Hawaii), Ed Markey (Massachusetts), Gary Peters (Michigan), Tammy Duckworth (Illinois), Jacky Rosen (Nevada), Ben Ray Luján (New Mexico), John Fetterman (Pennsylvania) and Lisa Blunt Rochester (Delaware).

The opposition here is almost solely based on Trump Derangement Syndrome. The only policy for these Democrats is to oppose all things Trump, even if that opposition makes no sense. This is not to say that Isaacman is a perfect choice. At the moment it is not clear exactly where he stands on Trump’s effort to shrink the waste in the federal government, including NASA.

Isaacman’s nomination still has to be confirmed by the full senate. Expect him to be approved handily, with the vote breaking down along similar party lines.

Astronaut Don Pettit, 70, wants to fly more missions in space

10:54 am

Despite his apparent significant discomfit upon landing last week after seven months in orbit, American astronaut Don Pettit is still eager to fly more times in space, despite celebrating his 70th birthday on the day he returned from ISS.

Pettit landed in Kazakhstan with his two Russian Soyuz MS-26 crewmates on April 20, 2025 local time in Kazakhstan, his 70th birthday. Cameras cut away as he was extracted from the capsule, raising concerns about his health. During a post-mission briefing today he explained that “I was right in the middle of emptying the contents of my stomach onto the steppes of Kazakhstan” and the cameraman kindly gave him the privacy he needed. He added that his body reacts to the return to Earth about the same way every time regardless of duration.

He looked fit today, just a week later.

At the briefing Pettit noted how returning to Earth can be very discomfiting, but with a little effort and time recovery occurs. He also noted how weightlessness is wonderful for older humans.

“I love being in space,” he said. “When you’re sleeping, you’re just floating, and your body, all those little aches and pains heal up. You feel like you’re 30 years old again and free of pain, free of everything. So I love being on orbit. It’s a great place to be for me and my physiology.”

Whether Pettit gets another flight is unclear. There are a lot of medical research reasons to fly an older individual like him in space. Whether NASA wants to do it is another question. The agency has generally been very timid about doing such things.

Pettit also claimed at this briefing that ISS could fly well past 2030, and shouldn’t be de-orbited then as planned. He however likely spent almost all his time in orbit on the American half, and likely has limited information about the stress fractures in the Russian Zvezda module.

SpaceX launches cargo Dragon to ISS; Problems with Tenacity?

8:55 am

Early this morning SpaceX successfully launched a cargo Dragon to ISS, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.

The first stage completed its fifth flight, landing back at Kennedy. The capsule is on its fifth flight, and is carrying significantly more cargo than previous SpaceX cargo missions because it has had to replace much of the cargo that would have been launched on a Cygnus capsule whose launch was cancelled because it had been damaged during transport.

Furthermore, as part of their updates on this mission NASA officials revealed that Sierra Space’s cargo mini-shuttle, Tenacity, is facing more delays, and is now not expected to launch until late this year. This Dream Chaser spacecraft had begun ground testing early in 2024, with a first launch planned for shortly thereafter. For reasons that have not been explained, that ground testing has now been going on for more than a year, and will apparently continue for most of 2025. My guess is that the spacecraft has experienced engineering problems during that testing, and has required fixes that neither Sierra Space nor NASA wishes to reveal.

The result has been that NASA has had a shortage of cargo vehicles to keep ISS supplied. A significant number of science experiments had to be removed from today’s Dragon to make room for consumerables. NASA officials also stated publicly during this update that it is now definitely considering using Starliner as a cargo vehicle on its next flight, a plan that previously had only been hinted at.

The leaders in the 2025 launch race:

45 SpaceX (with another launch scheduled for later today)
20 China
5 Rocket Lab
5 Russia

SpaceX now leads the rest of the world in successful launches, 45 to 35.

An American government program to get to the Moon is simply not necessary; If we let them Americans will do it on their own

12:08 pm

As a historian I often bring to any discussion of modern politics and our American space effort a perspective that is very alien to modern Americans. I see things as they once were in the United States back before we had a big overbearing federal government that everyone looked to for leadership. Instead, I see the possibilities inherent in a free nation led by the people themselves, not the government, as America was for its first two centuries.

This sadly is not how America functions today, and it is for that reason that as a nation we can no longer get great things accomplished routinely, as we once did.

Norwegian Amundsen, first to reach the south pole
Norwegian Amundsen, first to reach the south pole.

To understand how different the American mindset once was, consider just one example, the 19th century effort by numerous nations and individuals to plant their flag at both the north and south poles. While a handful of private American citizens mounted their own expeditions to reach the north pole, none attempted to do so in Antarctica. At both poles the bulk of the effort was done by other nations, sometimes on expeditions privately funded, and sometimes by expeditions with extensive government aid.

In the U.S. however there was no government program to compete in this race. Nor was their the slightest desire by Americans to create one. The attitude of Americans then was very straightforward. They found the race to get to the poles exciting and fascinating, and thoroughly supported the efforts of the explorers both intellectually and emotionally. They however had no interest in their government committing one dime of their tax dollars on its own campaign.

You see, they did not feel a need to establish American prestige in this manner. So what other nations got to the poles first? What mattered to Americans then was what each American wanted to do, and what Americans wanted to do in the 19th century was to settle the west and build their nation into a prosperous place to raise their children.

And so, the south pole was first reached by a Norwegian, followed mere weeks later by an Englishman. Americans played no major role in that early exploration. Nor did it harm America’s prestige in the slightest that it did not compete there. The nation was growing in wealth and prosperity, its citizens were completely free in all ways to follow their dreams, and everyone worldwide knew it.

America might not be the leader in far-flung exploration, but the world knew it was the leader in something as important if not more so, the idea that a nation and a government could be built on the premise that the citizen is sovereign, and that all law should be based on making that citizen’s life, liberty and the pursuit of happiness primary in all things.

And in the end, it did not really matter that the U.S. did not compete in that race to the poles. » Read more

Texas lawmakers now lobbying to move NASA headquarters to Houston

9:20 am

First it was Florida. Then it was Ohio. Now Texas lawmakers are lobbying the Trump administration to move NASA headquarters from Washington to Houston.

A coalition of Texas lawmakers is calling on President Donald Trump to relocate NASA’s headquarters to Houston when the office lease in Washington D.C. expires in 2028. U.S. Senator Ted Cruz and U.S. Rep. Brian Babin (R- Woodville) are leading the charge to make Houston the new landing spot for NASA headquarters. Several other Texas representatives signed onto the letter Wednesday urging Trump to make this shift.

That politicians in three different states are lobbying in this manner tells us it is almost certain that NASA’s headquarters is leaving DC. More important, it tells us that the agency’s entire bureaucracy — including its many scattered centers nationwide — are going to go through a major shake-up, including major reductions and closures. It appears Trump has made the headquarters a plum that these politicians are chasing in order to get them to agree to major cuts elsewhere.

Blue Origin completes ground simulation of Orbital Reef space station

9:16 am

According to a NASA press release today, Blue Origin has successfully completed a ” human-in-the-loop test” in a ground mock-up of the commercial Orbital Reef space station.

The human-in-the-loop test scenarios utilized individual participants or small groups to perform day-in-the-life walkthroughs in life-sized mockups of major station components. Participants provided feedback while simulating microgravity operations, including cargo transfer, trash transfer, stowage, and worksite assessments.

…The milestone is part of a NASA Space Act Agreement originally awarded to Blue Origin in 2021 and focused on the design progress for multiple worksites, floors, and translation paths within the station. This ensures a commercial station can support human life, which is critical to advancing scientific research in a microgravity environment and maintaining a continuous human presence in low Earth orbit.

Though this test might be providing useful information, it leaves me cold. While Blue Origin’s partner in this project, Sierra Space, has been testing real hardware for its LIFE inflatable module (as seen on the left side of the artist’s rendering above), Blue Origin itself appears to have built nothing real. Instead, it is following the old big space paradigm of companies like Boeing that invest none of its own money in development. Instead, the company uses NASA’s development money solely for PR mockups, in the hope the PR will convince NASA to give it the full contract, worth billions. Only then will the real work begin.

Boeing did this with Starliner, and we can all see now how well that turned out.

It also appears that the overall scale of Orbital Reef has been reduced significantly when comparing the current design above with the earlier artist renderings.

Based on this new information, I have dropped Orbital Reef to the bottom in my rankings of the four private space stations presently under development. While Starlab has built as little (following the same play-it-safe paradigm), the company has at least gotten its final design approved. It has also signed a partnership with the European Space Agency, giving it a powerful government backer in addition to NASA.

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for a 30 day mission. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth scheduled for this spring, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreement with the European Space Agency. It recently had its station design approved by NASA.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.

Maybe it finally is time we actually made these major budget cuts at NASA

12:05 pm

Chicken Little rules!

This past weekend the pro-government propaganda press has been in an outraged uproar concerning unconfirmed rumors and anonymous reports that the Trump administration is considering major cuts to NASA’s many science divisions and projects, cuts so large that several space missions, such as Mars Sample Return and the Roman Space Telescope, would have to be canceled. Here are just a few examples, with the first few the ones that broke the story:

Of this list, the Politico story is the most amusing. Suddenly this leftwing news outlet loves Musk again, since he is expressing opposition to these cuts. Just days before he was the devil incarnate because of his partnership with Trump in cutting government waste. Now that he might oppose these NASA budget cuts will lefties start buying Teslas again? Who knows? The depth of their thinking is often quite shallow and divorced from rationality.

As is typical of the propaganda press, all these stories focused on quoting only those opposed to the cuts, from Democrats in Congress to leftist activist organizations. Very few offered any alternative points of view. These reports were thus typical of the propaganda press and the Washington swamp whenever anyone proposes any cuts to any government program: We are all gonna die! Civilization is going to end! Only evil people would dare propose such ideas!

The truth is that there are many ample and rational reasons to consider major budget cuts to most of NASA programs. Like the rest of our bloated federal government, NASA is no longer the trim efficient government agency it was in the 1960s.

The structure of a ringed planetary nebula revealed in the infrared

9:18 am

A planetary nebula as seen by Webb
Click for original image.

Cool image time! Using the mid-infrared camera on the Webb Space Telescope, astronomers have been able to image in false colors the ringed structure surrounding a dying star about 1,500 light years away.

The nebula’s two rings are unevenly illuminated in Webb’s observations, appearing more diffuse at bottom left and top right. They also look fuzzy, or textured. “We think the rings are primarily made up of very small dust grains,” Ressler said. “When those grains are hit by ultraviolet light from the white dwarf star, they heat up ever so slightly, which we think makes them just warm enough to be detected by Webb in mid-infrared light.”

In addition to dust, the telescope also revealed oxygen in its clumpy pink center, particularly at the edges of the bubbles or holes.

NGC 1514 is also notable for what is absent. Carbon and more complex versions of it, smoke-like material known as polycyclic aromatic hydrocarbons, are common in planetary nebulae (expanding shells of glowing gas expelled by stars late in their lives). Neither were detected in NGC 1514. More complex molecules might not have had time to form due to the orbit of the two central stars, which mixed up the ejected material.

Though this false-color image of a planetary nebular is hardly ground-breaking (Hubble has been producing such pictures for decades), Webb’s better infrared data, in higher resolution, will help astronomers untangle the nebula’s complex geography. It remains however a question whether the improved capabilities of Webb were worth its $10 billion-plus cost. For that money NASA could have built and launched many different astronomical missions in the past two decades, many of which would have been able to match this data for far less.

NASA-Roscosmos barter deal to fly each other astronauts to ISS extended

8:55 am

In announcing its future crew assignments in early April NASA also confirmed that its barter deal with Russia to fly each other astronauts to ISS has been extended to 2027.

NASA announced April 3 that astronaut Chris Williams had been assigned to the Soyuz MS-28 spacecraft scheduled to launch to the ISS in November, joining Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev. The announcement came ahead of the April 8 launch of fellow astronaut Jonny Kim to the ISS on Soyuz MS-27.

The announcement of the Williams flight assignment was the first public indication by NASA that it has extended an agreement with Roscosmos for “integrated crews” on Soyuz and commercial crew flights to the ISS. Under the no-exchange-of-funds barter agreement, NASA astronauts fly on Soyuz spacecraft and Roscosmos cosmonauts fly on commercial crew vehicles to ensure that there is at least one American and one Russian on the station should either Soyuz or commercial crew vehicles be grounded for an extended period.

Russian sources in January 2025 had indicated the agreement had been extended, but this most recent non-announcement is the first confirmation by NASA.

One interesting change in the schedule revealed by this crew announcement is that Russia will be launching less frequently while extending its Soyuz missions. Previously Russia’s missions were six months long, the same length as NASA’s standard ISS mission. Now Russia will only launch every eight months. No explanation was given for this change, which will likely complicate the station’s already complex docking schedule. I suspect two reasons: First the Russian government probably needs to reduce costs, and flying less often serves that purpose. Second, Roscosmos officials probably want to also fly longer missions for research.

Congress: Let’s throw some more astronaut lives away so we can preen for the camera!

Jared Isaacman
Jared Isaacman

Here we go again: As I noted yesterday, the hearing this week of Jared Isaacman, Donald Trump’s nomination to become NASA’s next administrator, revealed almost nothing about what Isaacman plans to do once confirmed by the Senate. He very carefully kept his options open, even while he strongly endorsed getting Americans on the Moon as fast as possible in order to beat the Chinese there. When pressed by senators from both parties to commit to continuing the SLS, Orion, and Lunar Gateway projects to make that happen, Isaacman picked his words most cautiously. He noted that at the moment that plan seemed the best for getting to the Moon first. He also noted repeatedly that this same plan is years behind schedule and overbudget.

Like any smart businessman, Isaacman knows he cannot make any final decisions about SLS, Orion, or Gateway until he takes office and can aggressively dig into the facts, as administrator. He also knew he could not say so directly during this hearing, for to do so would antagonize senators from both parties who want those programs continued because of the money it pours into their states. So he played it coy, and the senators accepted that coyness in order to make believe they were getting what they want.

But what do these senators want? It appears our politicians (including possibly Trump) want NASA to launch humans to the Moon using SLS and Orion and do so as quickly as possible, despite knowing that both have real engineering issues of great concern. Instead, our elected officials want politics to determine the lunar flight schedule, instead of engineering, the same attitude that killed astronauts on Apollo 1 in 1967, on Challenger in 1986, and on Columbia in 2003. The engineering data then said unequivocally that things were not safe and that disaster was almost guaranteed, but NASA and Congress demanded the flights go on anyway, to serve the needs of politics.

With SLS and Orion it is now the same foolishness all over again. » Read more

Isaacman’s nomination hearing reveals nothing of note

10:00 am

Jared Isaacman
Jared Isaacman

The Senate committee on commerce, science, and transportation has just concluded its hearing on the nomination of Jared Isaacman as NASA administrator. Several take-aways:

First, there was little opposition to Isaacman on either side of the aisle. He will be confirmed easily.

Second, Isaacman was very careful to say nothing that might commit him to keeping all present Artemis programs (such as SLS, Orion, or Gateway) unchanged. He instead made it clear his goal is for NASA to attempt a parallel programs to establish a permanent American presence on both the Moon and Mars. This enthusiasm suggests he sees Starship as the vehicle capable of making those parallel programs possible.

In other words, he kept his options open. His goal is to get the Artemis program functioning more efficiently, and will do whatever is necessary to do so. He repeatedly made it clear that too many of NASA’s projects, including specifically Artemis, are routinely overbudget and behind schedule, and this must be fixed.

At the same time he said his goal is to get Americans back to the Moon ahead of the Chinese, and suggested that the present plan using SLS and Orion is likely the fastest way to do so. The technical issues that might make that program very unsafe for the astronauts however were never mentioned.

We shall see whether Isaacman as administrator will be so sanguine about sending Americans around the Moon within an Orion capsule with a questionable heat shield.

Ted Cruz: Isaacman in interview commits NASA to getting Americans to Moon fast

8:52 am

In a tweet posted yesterday, Senator Ted Cruz (R-Texas) revealed that in his private interview with Jared Isaacman, nominee for the post of NASA administrator, Isaacman “committed to having American astronauts return to the lunar surface ASAP.”

During our meeting, Mr. Isaacman committed to having American astronauts return to the lunar surface ASAP so we can develop the technologies needed to go on to Mars.

The moon mission MUST happen in President Trump’s term or else China will beat us there and build the first moonbase.

Artemis and the Moon-to-Mars Program are critical for American leadership in space!

It appears Cruz is trying to apply pressure on Isaacman and the Trump administration to not cancel SLS, as has been rumored for months. Though SLS and Orion have numerous issues, being too costly and cumbersome with risky designs that threaten the lives of any astronauts on board, cancelling them would likely delay any American manned mission to the Moon for several years, possibly allowing China to get there first.

We shall get a better idea of this situation at Isaacman’s nomination hearing, scheduled for tomorrow.

Russia launches three astronauts to ISS

10:57 pm

Russia early on April 8, 2025 successfully launched two Russians and one American to ISS on a six month mission, its Soyuz-2 rocket lifting off from its Baikonur spaceport in Kazakhstan.

They will dock with ISS after only two orbits, three hours after launch.

The leaders in the 2025 launch race:

40 SpaceX
18 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 40 to 32.

Senate schedules hearing to review Jared Isaacman’s nomination as NASA administrator

8:59 am

After months of delays, the Senate Committee on Commerce, Science, and Transportation yesterday finally announced it has scheduled for April 9, 2025 the confirmation hearing for Jared Isaacman’s nomination as NASA administrator.

I have previously speculated that the delay in scheduling this hearing was because there was opposition to Isaacman among Republicans both in the Senate and inside the White House, based on his past donations to the Democratic Party as well his previously strong support for Divesity, Equity, and Inclusion in his companies. It appears Isaacman must have eased those concerns when he began face-to-face private meetings with several Senate Republicans in the last two weeks, thus allowing the hearing to be scheduled.

Isaacman has been in Washington in recent days for one-on-one meetings with senators, a standard part of the confirmation process before a formal hearing. That included Sen. Jerry Moran (R-Kansas), who chairs the committee’s subcommittee on aviation, space and innovation, as well as the Senate Appropriations Committee’s subcommittee on commerce, justice and science, which funds NASA.

Moran said in an April 1 social media post that he met with Isaacman and discussed topics such as exploration and “a shared desire to beat our adversaries back to the Moon” as well as work on science and technology at NASA. “I am eager for the Commerce Committee to quickly conduct a confirmation hearing on his nomination to lead NASA,” Moran stated.

It now appears likely that this opposition is dissolving, and that Isaacman’s confirmation is likely.

Starliner’s troubles were much worse than NASA made clear

11:51 am

Starliner docked to ISS
Starliner docked to ISS.

According to a long interview given to Eric Berger of Ars Technica, the astronauts flying Boeing’s Starliner capsule on its first manned mission in June 2024 were much more vulnerable than NASA made it appear at the time.

First, the thruster problem when they tried to dock to ISS was more serious than revealed. At several points Butch Wilmore, who was piloting the spacecraft, was unsure if he had enough thrusters to safely dock the capsule to ISS. Worse, if he couldn’t dock he also did not know if had enough thrusters to de-orbit Starliner properly.

In other words, he and his fellow astronaut Sunni Williams might only have a few hours to live.

The situation was saved by mission control engineers, who figured out a way to reset the thrusters and get enough back on line so that the spacecraft could dock autonomously.

Second, once docked it was very clear to the astronauts and NASA management that Starliner was a very unreliable lifeboat.
