SpaceX launches a record 29 Starlink satellites

9:53 am

SpaceX early this morning successfully launched 29 Starlink satellites (the most yet on a single launch), its Falcon 9 rocket lifting off from Kennedy Space Center in Florida.

The first stage completed its 20th flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

52 SpaceX
23 China
5 Rocket Lab
5 Russia

SpaceX now leads the rest of the world in successful launches, 52 to 40.

Local voters approve establishing the town of Starbase at Boca Chica

8:37 pm

By a vote of 212 to 6 (out of about 300 eligible voters), the residents at the previously unincorporated coastal land strip at Boca Chica have approved a proposal to create the town of Starbase, with a mayor and two city commissioners.

The three candidates were all running unopposed for those positions. All three either work at SpaceX now, have worked there in the past, or have relatives employed by the company.

The mayor will be Robert “Bobby” Peden, 36. He has worked for SpaceX for the past dozen years, first at its MacGregor engine test site and now at Starbase as a vice president of test and launch. The two council members are Jenna Petrzelka and Jordan Buss. Petrzelka, 39, worked for SpaceX from 2012 to 2024 as an engineer. Her husband, Joe Petrzelka, is presently a SpaceX vice president. Buss, 40, started working for SpaceX in 2023 as a senior director of environmental health and safety.

The vote shifts much of the civil management away from the larger local county to the residence who live in the town itself. It is quite evident they will establish this city with the needs of SpaceX in mind. It also appears that the residents are fully in support of this.

As for launches here, I will still refer to it as Boca Chica. The town might be named Starbase, but the actual location is still Boca Chica.

Trump bypasses Boeing to get an newly refurbished 747 Air Force One

12:40 pm

Apparently disgusted with Boeing’s inability to get two Boeing 747s refurbished on budget and before he leaves office in 2028, the Trump administration has now enlisted another aerospace company, L3Harris, to refurbish a 747 formerly used by the Qatar government.

The president hopes to use the refurbished plane by the fall, sources told the outlet, and is regularly checking on its progress . This aircraft will be an interim solution until the Boeing jets are delivered.

The current presidential jets — which have been in service since the George H.W. Bush administration — are nearing their end of life.

Boeing’s conduct here has been truly disgraceful. It got the $3.9 billion fixed-price contract to refurbish two of its own 747s in 2018. Yet, despite having two working 747s — a plane it designed and built — it can’t refurbish them in less than a decade, while going over budget by about $2.4 billion, money it has to lay out because of the fixed-price nature of the contract.

FAA okays increase in SpaceX launches from Vandenberg from 36 to 50 per year

11:44 am

The FAA today approved an environmental reassessment at Vandenberg Space Force Base that permits SpaceX to increase its annual launches there from 36 to 50.

The reassessment determined (not surprisingly) that there was “no significant impact” on the environment caused by the increased number of launches.

We already have more than seven decades of empirical data at spaceports in both Florida and California that rocket launches do no harm to the environment, and in fact act to significantly protect wildlife and natural resources because they require the creation of large regions where no development can take place.

The real question should be this: Why is the federal government wasting taxpayer money on these reports? They are utterly unnecessary, and only serve to hinder the freedom of Americans while spending their taxes on make work that accomplishes nothing.

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.

Space Force awards twelve companies satellite development contracts worth $237 million

9:38 am

Capitalism in space: The Space Force yesterday announced that it has awarded twelve different aerospace companies contracts worth a total of $237 million for developing a variety of smallsat technologies to be used in future military satellite constellations.

The list of selected companies, announced May 1, includes defense and aerospace firms Lockheed Martin Corp. and General Atomics, as well as specialized space firms such as Blue Canyon Technologies, Loft Orbital Federal, Spire Global, Terran Orbital, and York Space Systems. Also named were Axient, Lynk Global, Orbit Systems, Turion Space, and the Utah State University-affiliated Space Dynamics Lab.

…Under the contract, vendors will build and integrate small satellite buses capable of carrying a variety of military experiments and sensors. These buses, often the size of a microwave or small refrigerator, serve as standardized platforms that can be customized to carry diverse payloads.

These contracts are part of the Trump administrations push to get the military to rely on the private sector for its needs. Though the private sector would general build things in the past for the Pentagon, often the design, construction, and even ownership was held entirely by the government. The companies didn’t have anything they could sell elsewhere. Now the design work is being left entirely to the companies, so that what they develop they will own, and will have the ability to market it to others.

Ursa Major wins contract for hypersonic test flight of its Draper rocket engine

9:29 am

The rocket engine startup Ursa Major has now won a $28.5 million contract from the Air Force Research Laboratory to do a hypersonic test flight using its Draper rocket engine.

The contract, announced May 1, covers both the flight demonstration and integration of the engine into a test vehicle, with work scheduled through early 2027. The project aims to advance U.S. capabilities in hypersonic weapons, a category of defense systems that has become a top Pentagon priority amid competition with China and Russia.

The Draper engine is designed to produce 4,000 pounds of thrust and was developed by Ursa Major with U.S. Air Force funding. Its key differentiator is its use of storable, non-cryogenic propellants — specifically a kerosene and hydrogen peroxide combination — that remain liquid at ambient temperatures. This contrasts with traditional rocket engines that rely on liquid oxygen, which must be kept at ultra-low temperatures and handled with complex cooling infrastructure.

It certainly does appear that the Pentagon is ramping up its hypersonic research with a slew of contracts to many different new commercial space startups. In addition to this deal, Rocket Lab, Varda, and Stratolaunch have won contracts for similar hypersonic testing, with Rocket Lab winning the most. No wonder a new company like Radian (see previous post) is switching its focus toward this research.

Rocket startup Radian now also building commercial reentry capsule

9:20 am

The rocket startup Radian Aerospace, which is attempting to build an orbital spaceplane that takes off and lands from a runway, has announced that it is also building a commercial reentry capsule that can be used for hypersonic testing.

The Seattle based company announced April 29 its intent to develop the Radian Reusable Reentry Vehicle (R3V), a spacecraft for hypersonics testing or returning payloads from space that also gives Radian flight experience in key technologies for its future Radian One spaceplane.

Livingston Holder, chief technology officer of Radian, said in an interview that the company was looking was ways to test Dur-E-Therm, the thermal protection system it is creating for Radian One. The company had recently completed tests of the system in a lab at NASA’s Glenn Research Center. “But, testing in a non-flight environment only gets you so far, so we were crafting how to test it in a more relevant environment.”

It appears the company has recognized that its spaceplane will take years to develop, and more years before it can bring in any revenue. An orbital capsule however can be developed much more quickly, and it also appears there are a lot of commercial and military customers for it.

  • 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.

Giant galactic magnetic filament disturbed by pulsar

12:18 pm

A giant galactic filament disturbed by a 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

11:54 am

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.

Astronomers discover a cluster of a thousand very young stars that is flying apart for unknown reasons

10:01 am

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

9:45 am

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

9:27 am

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.

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.

Chinese crew returns safely after six months in space

9:36 am

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.

The American Geophysical Union: the privileges of government-paid scientists must come above the Constitution and the ordinary citizens who pay the bills

2:08 pm

The American Geophysical Union, where science is no longer practiced
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

12:20 pm

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

11:09 am

Middle East, showing Oman's proposed spaceport
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.
