- Claiming budget uncertainty, NASA delays by a year deadline for relatively small astrophysics mission proposals
There are budget uncertainties, but I have no doubt this decision is mostly aimed at ginning up opposition to any cuts at NASA at all. It’s an old NASA tactic: Threaten cuts in a broad indiscriminate manner to get Congress and the President to retreat from any cuts. Today’s specific decision tells me we really need a new hard-nosed administrator at NASA who won’t let lower management play these games. Whether Isaacman is that man however remains unknown.
- Rocket startup Stoke Space touts static fire tests of two of its engines, both running above 100%
The company had hoped to do its first launch this year, but that will likely slip to 2026, mostly because of environmental red tape at its launch site in Florida.
- India’s space agency touts its astronaut flying on the fourth Axiom tourist mission to ISS
Launch is now scheduled for May 29, 2025.
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. If you buy it from 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
Giant galactic magnetic filament disturbed by pulsar
Click for original image.
Cool image time! The false-color X-ray picture to the right, reduced and sharpened to post here, was released today by the science team for the Chandra X-ray Observatory, showing some interesting astronomical features about 26,000 light years away near the galactic center.
The press release attempts to catch the ignorant press’s interest by referring to the long white filament that crosses this image as “a bone”, implying that this is similar to a medical X-ray of a person’s bones. Hogwash. What we are looking at is a filament of energized particles forced into this long thin shape by the magnetic field lines that exist in the central regions of the Milky Way galaxy.
What makes this X-ray data of interest is shown in the inset. The pulsar appears to have disturbed that filament, pulling those energetic particles away to form a trailing cloud.
In the first composite image, the largely straight filament stretches from the top to the bottom of the vertical frame. At each end of the grey filament is a hazy grey cloud. The only color in the image is neon blue, found in a few specks which dot the blackness surrounding the structure. The blue represents X-rays seen by NASA’s Chandra X-ray Observatory.
In the annotated close-up, one such speck appears to be interacting with the structure itself. This is a fast-moving, rapidly spinning neutron star, otherwise known as a pulsar. Astronomers believe that this pulsar has struck the filament halfway down its length, distorting the magnetic field and radio signal.
As big and empty as space is, there is still enough stuff within it to cause these kinds of interactions. It just requires the luxury of endless eons, something that we as short-lived humans have trouble conceiving.
A Martian river of ice
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on January 26, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labeled it “Looking for Gullies” because the researchers were likely searching for such geological features on the cliff wall that runs down the right side of the picture.
What is more significant however about this picture is the glacier features in the canyon below that cliff. The downhill grade is to the southwest, and it is very evident that the canyon is filled with glacial-type debris, flowing down that grade. Along the base of the cliff the flow seems focused but squeezed, the larger blocks to the west moving slower and thus acting like a wall themselves. In between the flow moves like rapids in a narrow part of a river, albeit in slow motion.

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.
Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.
Astronomers discover a cluster of a thousand very young stars that is flying apart for unknown reasons
Astronomers using data from Gaia, which measured the precise distance and position of more than two billion stars, have discovered a very young cluster of a thousand stars that is flying apart for unknown reasons.
The cluster is about 650 light-years away in Ophiuchus, the Serpent Bearer, and has been nicknamed “Ophion” in honor of its resident constellation. “Ophion is filled with stars that are set to rush out across the galaxy in a totally haphazard, uncoordinated way, which is far from what we’d expect for a family so big,” said Huson in a statement. “What’s more, this will happen in a fraction of the time it’d usually take for such a large family to scatter. It’s like no other star family we’ve seen before.”
You can read the peer-reviewed paper here [pdf]. The scientists proposed several theories that might explain what disrupted this cluster so early in its history, but none are very convincing, with the data available.
Scandal at Great Britain’s first spaceport at Cornwall airport
A local council in Cornwall has withdrawn £200K of funding from spaceport operations at the local airport — the first spaceport established in Great Britain where Virgin Orbit launched its last flight — because one council member responsible for distributing the funds was also at the same time getting a job at the spaceport without telling anyone.
The decision has come after it was revealed that the council’s then cabinet member for the economy Cllr Louis Gardner – who oversaw SPF allocation as part of his portfolio – was actually in the process of getting a top job at the Spaceport when he was part of an Economic Prosperity Board meeting on February 27. He was among members who agreed to give the space hub the £200k levelling up money. He didn’t declare an interest during the meeting.
Days later it was announced he had got the £70,000 head of future air and space role, which sees him controlling a budget which would have included the £200,001 fund previously agreed by him and other Economic Prosperity Board members. On accepting the Spaceport role he stood down from his position as the local authority’s Conservative cabinet member for the economy and will retire as a Newquay councillor on Cornwall Council at the election tomorrow (Thursday, May 1).
It appears this kerfuffle is also linked to the continuing collapse of the conservative Tory Party in Great Britain. Gardner is a Tory, and it appears his actions convinced two other Tory councilors to publicly break from that party and join Nigel Farage’s Reform party.
Before the meeting even started there was no escaping what many are calling a “scandal” when Tory rebels Cllr Steve Arthur (Perranporth) and Cllr John Conway (Launceston South) arrived wearing NASA spacesuits, much to the amusement of many of their colleagues. The councillors, who resigned from the Conservative group to start an independent non-aligned group, said they had pulled the stunt to highlight the issue.
The decision to withdraw this money however makes sense from another perspective. The spaceport has no customers, as there are literally no rocket companies in existence at present able to launch from an airport runway. Cornwall’s only customer, Virgin Orbit, went bankrupt after its one launch there failed.
Nor should anyone expect any new rocket companies to appear eager to use Cornwall. The red tape that Virgin Orbit had to clear to launch took almost a year, and that delay was part of the reason the company went belly-up. It used up its cash reserves waiting for Great Britain’s bureaucrats to fill out forms.

Startup that builds maneuverable surveillance satellites raises $260 million in private investment capital
The startup True Anomaly has raised $260 million in private investment capital in order to fully develop its Jackal maneuverable satellite, designed to travel and inspect other orbiting satellites for the military.
The Colorado-based company announced April 30 that it closed a Series C round that combines equity and debt financing. Venture firm Accel led the round, with participation from Meritech Capital and several existing backers including Eclipse, Riot Ventures, Menlo Ventures, and Narya. Stifel Bank is providing the debt portion of the raise.
Only founded in 2022, True Anomaly has already flown two test missions of Jackel. With these new funds, it plans four more flights in the next year and a half.
There are already a number of other companies building maneuverable satellites. Most however are focused on providing tug services for commercial satellites or for finding and removing space junk. True Anomaly is instead targeting the military as its customer, which appears a smart move because no one else has, up to now.

- Today marks the tenth anniversary of the end of the Messenger mission to Mercury
The spacecraft was the first to orbit Mercury, and operated there for four years.
Psyche asteroid probe experiences an unexplained engine problem
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
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.
Chinese crew returns safely after six months in space
A Chinese crew of three safely landed in northern China today after completing a six month mission on China’s Tiangong-3 space station.
The return capsule of the Shenzhou-19 crewed spaceship, carrying astronauts Cai Xuzhe, Song Lingdong and Wang Haoze, touched down at the Dongfeng landing site in north China’s Inner Mongolia Autonomous Region on Wednesday. The three astronauts are all in good health condition, according to the China Manned Space Agency.
Lots of pictures of the landing and recovery at the link, but that’s pretty much the entire text of the press release from China’s state-run press. As that state-run press does routinely, it repeats that same text as the caption under every picture, over and over again, changing it only slightly for the close-up pictures of each astronaut.
A new crew took over for this one on Tiangong-3, beginning their own six month mission. At the moment China has completed three years of continuous occupation out of a planned ten-year mission.

- Russia now says its Spectr-UV space telescope will launch in 2031
It was originally supposed to launch in 1997.
- Russia re-confirms its unmanned lunar program previously outlined in 2023, except now it gives few specific target dates
Expect Russia to miss even these dates.

Supposedly going to begin launches in 2026, but if you believe that, I have a bridge in Brooklyn I can sell you cheap.
- New images of failed 1972 Soviet-era Venera lander whose Earth orbit is about to decay
The pictures don’t really show much, except that it appears smaller than a typical Starlink satellite (shown in comparison). Designed however to survive Venus’s thick and hot atmosphere, it will still likely hit the ground when its orbit decays in the second week of May.
The American Geophysical Union: the privileges of government-paid scientists must come above the Constitution and the ordinary citizens who pay the bills
The American Geophysical Union, where
science is no longer practiced
In a public letter issued late yesterday, the American Geophysical Union (AGU) announced it has joined a lawsuit attempting to make the salaries, jobs, and various research grants of scientists immune from cancellation or the budget cuts that have been ordered by the elected president of the United States, Donald Trump.
Plaintiffs assert that such a sweeping Executive Order — which would impact hundreds of thousands of federal workers — goes far beyond the authority of the President to direct, and that such a massive reorganization of federal agencies must be planned in accordance with law and approved by Congress. AGU’s role in the case will involve illustrating the extensive ways in which scientists and the public will be irreparably harmed by the execution of the President’s order, in particular through proposed mass terminations at NOAA, the Department of Agriculture, Department of Energy, the Environmental Protectional Agency, and the National Science Foundation.
“This Executive Order is demanding layoffs on such a massive scale that they will have drastic, cascading effects on our members, the global scientific community, and the public,” said Janice R. Lachance, Interim Executive Director and CEO of AGU. “From forecasting severe weather and ensuring healthy crops to preventing uncontrollable wildfires and preparing communities for sea level rise, fully functioning federal scientific agencies are critical.” [emphasis mine]
The highlighted phrases show the priorities. The public comes last. More important are “federal workers,” the “members” of the AGU, and “the global scientific community.” Moreover, the letter reeks of privilege and smug superiority. It assumes that the paychecks from the taxpayers must never end, no matter what. The very idea that the president — duly elected by the American people and whom the Constitution vests with the sole power to run the executive branch of the federal government — should actually do what he promised the voters during the campaign actually offends them. “We come first! To hell with what the public wants!”
None of this should surprise anyone. The AGU, along with most national scientific organizations, has been corrupted by leftist politics for decades. It threw out the fundamentals of objective science years ago when it declared that it will reject any paper that does not support the theory of human-caused global warming. Its PR department has consistently reinforced this unscientific bias, pushing global warming in practically every press release.
And if you still have doubts about its leftist agenda divorced from objective science, you need only read its own description at the end of yesterday’s letter, outlining the organization’s priorities:

Firefly launch fails
In its first launch attempt in 2025, Firefly’s Alpha rocket had a problem shortly after the first stage separated from the upper stage and the upper stage’s engines began firing. The upper stage began swivel somewhat though it appeared to stablize after a few seconds.
Subsequent reports confirmed that the stage failed to reach orbit.
The launch of the FLTA0006 mission appeared to go as planned until stage separation about 2 minutes and 35 seconds after liftoff. A cloud suddenly formed between the two stages, and video showed what appeared to be debris falling away as the upper stage continued its ascent.
A camera on the upper stage also showed debris falling away from it seconds after separation. The nozzle for the single Lightning engine in the upper stage appeared to be seriously damaged, if not missing entirely.
In a statement four and a half hours after launch, Firefly confirmed that the upper stage and its payload failed to reach orbit because of the stage separation issue. “The rocket then experienced a mishap between stage separation and second stage ignition that led to the loss of the Lightning engine nozzle extension, substantially reducing the engine’s thrust,” the company stated.
Alpha has now launched a total of six times, but only two of those launches were completely successful. Two of the other launches got their payloads into orbit, but not at the proper positions. In all the failures but one, the problems were with the upper stage. Today’s failure is another example of this.
Weather scrubs first test of experimental vertical take-off/landing rocket built by Middle Eastern startup
The Middle East, showing the location of
Oman’s proposed spaceport at Duqm.
The first test flight of Horus-4, an experimental vertical take-off/landing rocket built by the Middle Eastern startup Advanced Rocket Technologies, was scrubbed yesterday supposedly due to weather.
The launch had been part of the first public event at Oman’s proposed Etlaq spaceport near the coastal city of Duqm.
Oman’s Etlaq spaceport opened its doors to the public for the first time on Monday, hosting a three-day fan zone experience designed to spark interest in space exploration among the country’s youth.
The event had originally been scheduled to culminate with the launch of the Horus-4 experimental rocket, developed by London company Advanced Rocket Technologies (ART). But unsuitable weather forced the test flight to be delayed, with a new launch date to be announced soon.
Pupils from across Duqm – a coastal town about 550km from Oman’s capital city of Muscat – took part in a variety of educational activities. The fan zone, called Etlaq FX, included four tents that were placed about 3km from the spaceport’s operations team and launch pad, with the site overlooking the Arabian Sea.
At the moment the Duqm spaceport is mostly a launch site for small suborbital rockets. Oman however is pushing hard to sell it to rocket companies, with launches of such small rockets by a variety of startups and Middle Eastern nations scheduled throughout the rest of this year.
Of those launches the most ambitious is that of Advanced Rocket Technologies Horus-4. If it flies and lands successfully, it will be a major technological achievement for the company, and the Arab part of the Middle East.
Astronaut Don Pettit, 70, wants to fly more missions in space
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.
Head of the FAA’s commercial space office takes Trump buy-out
Kelvin Coleman, the head of the FAA office that regulates and issues all launch licenses, has now decided to accept the buy-out offered by the Trump administration and retire.
Coleman has led the FAA’s Office of Commercial Space Transportation, known as AST, since 2022, after being named deputy associate administrator in 2017. During that time, the amount of commercial launch activity has grown enormously, from 23 licensed launches in 2017 to 157 in 2024.
That has put a strain on the office, which the FAA has responded to by seeking additional staff and other resources, as well as streamlining the licensing process. The latter included new launch and reentry licensing regulations, called Part 450, that took effect in 2021.
Industry, though, has complained about the implementation of Part 450, leading the FAA to create a space-related Aerospace Rulemaking Committee, or SpARC, to collect industry input on ways to improve Part 450. FAA officials said at the Commercial Space Conference in February that the SpARC was expected to complete its work by July, and that it was working on other improvements, such as a new electronic system for license applications.
It was apparently under Coleman’s leadership that Part 450 was created and implemented. The FAA claimed it would streamline the licensing process. Instead, it did the exact opposite. Under Coleman and Part 450, the red tape from the FAA actually increased significantly, to the point that it apparently caused the several rocket startups to close down.
It is quite possible therefore that Coleman decided to take the buy-out because he suspected his time at the FAA was limited anyway, that the Trump administration wanted him out.
