Democrats: “We have the right to vandalize Teslas, and if you try to stop us you are fascists!”

1:44 pm

The modern Democratic Party
The modern Democratic Party

My headline above paraphrases somewhat the insane position of Congressman Dan Goldman (D-New York), but so slightly that I think I can be forgiven. In a tweet posted earlier this week, Goldman’s reaction to a new federal task force aimed at investigating and catching the terrorists who have been firebombing Tesla dealerships and vandalizing Tesla cars was as follows:

This is the political weaponization of the DOJ. Trump uses his official authority to defend his benefactor Elon Musk. The FBI then creates a task force to use our law enforcement to “crack down” on adversaries of Musk’s.

Where are the Republicans so opposed to “lawfare”?

In other words, any effort to stop leftist rioters, looters, and vandals is misuse of government power, and is thus further justification for more leftist rioting, looting, and vandalism. According to Goldman, these thugs have the right to do anything they want to hurt Elon Musk, his businesses, his products, and his customers, simply because Musk no longer supports the Democratic Party and is trying to eliminate the fraud and corruption that has been impregnated within the entire federal government by that very party.

This is the Democratic Party today, a supporter of violence, censorship, and brutality, all in the name of gaining power. Nor is Goldman an exception at the top. » Read more

NASA/Boeing: More Starliner ground engine tests throughout 2025; Next flight likely in 2026

9:51 am

Starliner docked to ISS
Starliner docked to ISS.

According to a press release from NASA late yesterday, both the agency and Boeing will spend most of the rest of this year doing additional Starliner static fire engine tests of thruster redesigns before considering another flight of the capsule to ISS.

NASA and Boeing are working to finalize the scope and timelines for various propulsion system test campaigns and analysis that is targeted throughout the spring and summer. Testing at White Sands Test Facility in New Mexico will include integrated firing of key Starliner thrusters within a single service module doghouse to validate detailed thermal models and inform potential propulsion and spacecraft thermal protection system upgrades, as well as operational solutions for future flights. These solutions include adding thermal barriers within the doghouse to better regulate temperatures and changing the thruster pulse profiles in flight to prevent overheating. Meanwhile, teams are continuing testing of new helium system seal options to mitigate the risk of future leaks.

“Once we get through these planned test campaigns, we will have a better idea of when we can go fly the next Boeing flight,” said Steve Stich, manager, NASA’s Commercial Crew Program at the agency’s Kennedy Space Center in Florida. “We’ll continue to work through certification toward the end of this year and then go figure out where Starliner fits best in the schedule for the International Space Station and its crew and cargo missions. It is likely to be in the timeframe of late this calendar year or early next year for the next Starliner flight.”

The release indicated that the goal is to get the capsule certified prior to the next flight so that it can carry a crew on a fully operational mission. The release however left open the option that this next ISS flight might instead be an unmanned cargo mission. The announcement said nothing about who will pay for this flight. Under Boeing’s fixed-priced contract, it should foot the bill, but no one should be surprised if NASA works a deal to funnel money Boeing’s way.

Meanwhile, the agency has changed some of the crew assignments for that first and long-delayed operational Starliner flight, switching astronaut Mike Fincke from that mission to the next Dragon mission to launch later this year. (I suspect Fincke wanted to fly again, and was tired of sitting on his hands waiting for Boeing to get Starliner working.)

NASA experiment on Blue Ghost demonstrates the ability to repel the Moon’s abrasive dust

9:31 am

Before and after
Click for original blink movie.

In a press release yesterday, NASA revealed that one of its technology experiments on Firefly’s Blue Ghost lunar lander successfully demonstrated the ability to repel the Moon’s abrasive dust from the surfaces of various materials.

Lunar dust is extremely abrasive and electrostatic, which means it clings to anything that carries a charge. It can damage everything from spacesuits and hardware to human lungs, making lunar dust one of the most challenging features of living and working on the lunar surface. The EDS technology uses electrodynamic forces to lift and remove the lunar dust from its surfaces. The “before” image highlights the glass and thermal radiator surfaces covered in a layer of regolith, while the “after” image reveals the results following EDS activation. Dust was removed from both surfaces, proving the technology’s effectiveness in mitigating dust accumulation.

The images to the right, taken from a blink movie showing the change after the EDS technology was used, suggest that though this technology does work, it is not yet wholly successful in some cases. The thermal radiator was not cleared entirely of dust. More engineering research will be necessary, both on the Moon and here on Earth.

Nonetheless, this success is important and a major step forward for future exploration of the Moon, Mars, and the asteroids. In all these places dust is going to pose a major problem for equipment and spacesuits. New techniques must be developed to clean the dust away, since traditional Earth-based cleaning methods using water will not be available.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

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

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

 

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

 

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

Boeing now faces criminal trial for two 737-Max crashes that killed 346

9:13 am

Boeing Logo

In a criminal case against Boeing that has been going on since two Boeing 737-Max planes crashed in 2018 and 2019, the company now faces a criminal trial scheduled to begin in June over its admitted lies to the FAA about the airplane’s technical flaws that led directly to those crashes.

[T]he criminal charge pending against Boeing arises out of two deadly crashes of Boeing 737 MAX aircraft in 2018 and 2019. A Justice Department investigation uncovered the fact that Boeing had lied to the FAA about the safety of the aircraft—lies that led directly and proximately to the crashes killing 346 passengers and crew. On January 7, 2021, the Justice Department filed a criminal information with a one-count conspiracy charge against Boeing, alleging that “From at least in or around November 2016 through at least in or around December 2018, in the Northern District of Texas and elsewhere, the Defendant, The Boeing Company, knowingly and willfully, and with the intent to defraud, conspired and agreed together with others to defraud the United States by impairing, obstructing, defeating, and interfering with, by dishonest means, the lawful function of a United States government agency.”

In 2021 Boeing admitted to these charges as part of a plea deal with Justice, whereby prosecution would be deferred for three years if Boeing took certain actions to clean up its act. When that deal expired in 2024, Justice determined that Boeing had failed to live up to its agreement. Rather than go to criminal trial however government lawyers instead attempted twice to settle the case by having Boeing pay a big fine, first $243 million and then $455 million. In both cases the deals fell through when lawyers for the victims’ families objected.

After many further delays, the judge in the case has now taken action and set a trial date of June 23, 2025.

The article at the link is written by one of the lawyers for the victims, so it of course has a very decidedly anti-Boeing slant. Nonetheless, the situation for the company is very dire. It has already admitted guilt in the 2021 plea deal. It will be practically impossible for it to avoid a guilty sentence at that trial, resulting in gigantic payouts that could very well bankrupt the company.

I wonder however if instead of charging just the company, a corporation, the Justice Department should also have indicted the specific individuals at Boeing who committed the fraud itself. Those people are the ones responsible, not the entire company. Leaving them out of the case allows them to literally get away with the equivalent of second degree murder for “depraved indifference.”

For example, the CEO of Boeing at the time of those 737-Max crashes, Dennis Muilenburg, was fired in 2019 shortly after the crashes, suggesting the company was aware of his culpability in the situation. And what about the specific managers who filed false reports with the FAA? Do they all get off scot free?

As it stands now, the case is likely to destroy Boeing itself, harming thousands of innocent employees who had nothing to do with this fraud or the 737-Max. It will also do great harm to Boeing’s many other contracts with the government, NASA, and other private airline companies.

Then again, maybe it is time for this company to go. It surely hasn’t demonstrated in the past decade any ability to build anything reliably.

Webb finds more elements not possible so soon after the Big Bang

11:19 am

A galaxy that shouldn't be there
Click for original image.

The uncertainty of science: Using the Webb Space Telescope, astronomers have now detected emissions of hydrogen from a galaxy that exists only 330 million years after the Big Bang that simply shouldn’t be possible, based on present cosmological theory.

The false-color infrared image of that galaxy is to the right, cropped to post here. At that distance, 13.5 billion light years away, all Webb can really see is this blurry spot. From the press release:

In the resulting spectrum, the redshift was confirmed to be 13.0. This equates to a galaxy seen just 330 million years after the big bang, a small fraction of the universe’s present age of 13.8 billion years old. But an unexpected feature stood out as well: one specific, distinctly bright wavelength of light, known as Lyman-alpha emission, radiated by hydrogen atoms. This emission was far stronger than astronomers thought possible at this early stage in the universe’s development.

“The early universe was bathed in a thick fog of neutral hydrogen,” explained Roberto Maiolino, a team member from the University of Cambridge and University College London. “Most of this haze was lifted in a process called reionization, which was completed about one billion years after the big bang. GS-z13-1 is seen when the universe was only 330 million years old, yet it shows a surprisingly clear, telltale signature of Lyman-alpha emission that can only be seen once the surrounding fog has fully lifted. This result was totally unexpected by theories of early galaxy formation and has caught astronomers by surprise.”

In more blunt terms, the theory that the haze would clear only one billion years after the Big Bang appears very wrong. This result is also similar to the story earlier this week about the detection of oxygen in a similarly early galaxy, oxygen that could not possibly be there only a few hundred million years after the Big Bang. Not enough time had passed for the number of star generations needed to produce it.

You can read the peer-reviewed paper here. While the Big Bang theory is hardly dead, the data from Webb continues to suggest it either needs a major rethinking, or there is something fundamentally wrong with it.

UK government continues to dither about fixing its serious red tape issues relating to space

10:11 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

Three different news articles from three different British news sources in the past 24 hours strongly suggest that the factions within the government of the United Kingdom are still unfocused about fixing the serious regulatory red tape that not only bankrupted the rocket startup Virgin Orbit but has delayed for years the first launches from either of its two proposed spaceports in Scotland. The headlines might sound positive, but the details are far less encouraging:

The first article describes the comments of industry officials at a House of Lords committee hearing, where they pleaded with the government to help foster a British launch capability. Sounds good, eh? The problem is that such hearings have been held now repeatedly for the last several years, and Britain’s parliament has done nothing to reform its very cumbersome, complex, and byzantine launch licensing process. Getting approvals still takes months if not years.

It appears that this particular hearing is no different. While it provided government officials the chance to express sympathy for industry in front of news cameras, there is no indication parliament will do anything to fix anything.

The second article describes comments by the Labor government’s technology secretary Peter Kyle before the House of Commons. » Read more

NASA: Cygnus capsule damaged in transit to launchpad is too damaged to launch

9:25 am

According to this Ars Technica article today, the Cygnus cargo capsule that was reported to be damaged several weeks ago while being transported in a shipping container to its launchpad has now been found too damaged for launch, according to NASA.

On Wednesday, after a query from Ars Technica, the space agency acknowledged that the Cygnus spacecraft designated for NG-22 is too damaged to fly, at least in the nearterm. “Following initial evaluation, there also is damage to the cargo module,” the agency said in a statement. “The International Space Station Program will continue working with Northrop Grumman to assess whether the Cygnus cargo module is able to safely fly to the space station on a future flight.” That future flight, NG-23, will launch no earlier than this fall.

As a result, NASA is modifying the cargo on its next cargo flight to the space station, the 32nd SpaceX Cargo Dragon mission, due to launch in April. The agency says it will “add more consumable supplies and food to help ensure sufficient reserves of supplies aboard the station” to the Dragon vehicle.

It will be at least half a year before the next Cygnus will be ready for launch.

As the article notes (and immediately occurred to me also), this incident creates an opportunity to help Boeing and Starliner. Last year there were rumors that NASA might pay Boeing to fly Starliner as an unmanned cargo flight to ISS. This would allow the company to test its fixes to the capsule without having to pay for another test flight. These rumors however have faded since Trump took power, suggesting the new administration did not want to pay that extra money.

The loss however of this Cygnus cargo mission not only frees up NASA cash that could be transferred to a Starliner cargo mission, it frees up a slot in the cargo schedule. It actually makes a lot of sense to give Boeing the job.

Unfortunately, unless someone higher up in the Trump administration (possibly Trump himself) makes the decision, we should not expect any action on this idea until NASA’s new administrator is confirmed by the Senate and takes office. And that event remains in limbo at this point.

In the meantime, NASA has no redundancy for getting cargo to ISS, and must rely entirely on SpaceX and its Dragon cargo capsules. A third option, Sierra Nevada’s Tenacity Dream Chaser reusable cargo mini-shuttle, is still not ready to launch. It was supposed to do its first test flight to ISS a year ago, but could not because ground testing had to be done first, and for reasons that are very unclear, it appears that testing has not yet been completed.

Two more launches today

11:27 pm

Since this morning’s launch by Rocket Lab, there have been two more launches. First, SpaceX placed another 27 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its 24th flight, landing on a drone ship in the Pacific. This is presently SpaceX’s second most used booster, exceeded only by one that has flown 26 times.

Next China launched a communications satellite for use by its space station and other government space missions, its Long March 3B rocket lifting off from Xichang spaceport in southwest China. No word on where the rocket’s core stage and four side boosters, all using very toxic hypergolic fuel crashed inside China.

The leaders in the 2025 launch race:

35 SpaceX
15 China
5 Rocket Lab
4 Russia

SpaceX still leads the rest of the world in successfully launches, 35 to 27.

Space Force finally certifies ULA’s new Vulcan rocket for commercial military launches

9:26 pm

After significant delays in developing ULA’s new Vulcan rocket, and then further delays after the rocket’s second test launch (which experienced technical issues), the Space Force today finally announced that it has certified the rocket, thus allowing ULA to proceed with several military launches that have been stalled for months. From ULA’s press release:

In September 2016, ULA entered into an agreement with the U.S. Air Force and outlined the plan to certify Vulcan according to the Air Force’s New Entrant Certification Guide. Over the last few years, the collective ULA and Space Force team have completed 52 certification criteria, including more than 180 discrete tasks, two certification flight demonstrations, 60 payload interface requirement verifications, 18 subsystem design and test reviews, and 114 hardware and software audits.

What was not revealed was the criteria the Space Force used to finally put aside as critical the loss of a nozzle on one of Vulcan’s two side booster’s during the second test launch. While the rocket successfully got its payload into the proper orbit, for a booster to lose a nozzle is not trivial. ULA has recently said it had found the cause and has fixed it, but few details have been revealed. Nor has this new announcement revealed any further details about the fix.

Regardless, this certification is very good news for ULA. Expect it to move as quickly as it can (which will seem slow in comparison to SpaceX) to launch a number of delayed military launches.

A major very public protest against Hamas by Gazans

12:04 pm

Protest against Hamas, in Gaza
Protest against Hamas, in Gaza

In what might signal a major turning point in Israel’s war against Hamas, many hundreds of Gazans earlier this week marched through the ruins protesting against Hamas quite publicly and apparently with no fear.

Hundreds of Gazans marched through the northern town of Beit Lahiya carrying white flags and chanting anti-Hamas slogans, according to videos posted from the scene, which showed participants calling for peace, press coverage, and the release of hostages.

In a rare public uprising against Hamas rule in Gaza, demonstrators took to the streets outside the Indonesian Hospital in northern Gaza. Footage shared on social media on Tuesday captured a crowd of protesters demanding an end to what they called “tyrant rule,” with chants of “Out, out, out! Hamas out!” and “We want to live!” echoing through the streets.

The images to the right are a screen capture from this video. The tweet claims thousands participated in this protest, with chants of “Down with Hamas, we’ve had enough, Hamas!”

Hamas has controlled Gaza for almost two decades. In that time any hint of protest against it has been routinely met quickly with brutal and violent retaliation. It now appears however that its power within Gaza has been severely damaged by Israel’s aggressive war, killing one leader after another with amazing efficiency.

Recently for example I have noticed in watching videos posted by Hamas supposedly showing Gazans cheering its effort, that if you look closely at the people in the crowd, many do not appear to be enthusiastic or supportive. Instead, these so-called Hamas supporters often have appeared sullen, joining the chants reluctantly almost out of fear.

These new protests against Hamas I think give us a better sense of the situation. Even though there is ample evidence that until recently Gazans of all stripes supported Hamas and were willing to eagerly aid it in its terrorist acts of murder, rape, and torture, it appears that Hamas’s failures in the war are finally taking their toll on its popularity.

These protests are a great opportunity for Israel, if it moves fast. If it can find and identify these protesters, especially their leaders, and protect them, it will further isolate Hamas and make its destruction more likely. It will also sow the seeds of a new leadership in Gaza that might actually be willing to live in peace with Israel.

As Space Force switches to capitalism model for its satellites, it will also not name the companies it hires

9:58 am

Capitalism in space: The main reason President Trump got the Space Force established in his first term was because the Air Force resisted rethinking its space military operations. It insisted on building large government-built satellites that took years to complete and always went overbudget and behind schedule.

The creation of the Space Force gave new people the ability to push for a major change, switching to the capitalism model whereby the government designed and built nothing but instead acted as a customer buying what it needed from the private sector. In addition, it allowed a major shift from those big satellites — easy targets for destruction — to the large private constellations of many small satellites, cheap to build and launch and difficult for other militaries to take out.

The Space Force — in order to protect the satellite companies it hires to build these satellites — has now announced that it will no longer publish the names of those companies.

The U.S. Space Force plans to keep the names of commercial companies participating in its new space reserve program under wraps, aiming to protect them from potential adversary threats as commercial satellites play a growing role in military operations.

Col. Richard Kniseley, director of the Space Force’s Commercial Space Office, said companies signing agreements under the Commercial Augmentation Space Reserve (CASR) program can disclose their participation but are not required to. “That potentially puts a target on their back,” Kniseley told SpaceNews, underscoring the risk to private-sector firms providing space-based services during wartime.

Under this program, the Space Force has already signed contracts with four satellite companies, but the names remain undisclosed.

Though there is some logic to this decision, it carries great risk of corruption and misbehavior. Almost every time government bureaucrats and private companies are allowed to work in secret we routinely see kickbacks, bribery, and contract payoffs. And don’t expect congressional oversight to prevent such things, since there is now ample evidence from DOGE that our federal lawmakers have been quite willing to take their own payoffs to allow such corruption to prosper.

The switch to capitalism by the Pentagon is unquestionably a good thing. It will get more done for less. Letting it act in secrecy is a mistake however. Better to live with the risk of attack than allow our government and the companies it issues big money contracts to do things behind closed doors.

Parker completes 23rd close fly-by of Sun, matching record set by its previous fly-by

9:42 am

The Parker Solar Probe on March 22, 2025 successfully completed its 23rd close fly-by of Sun, matching the distant and speed records set by its previous fly-by in December 2024.

NASA’s Parker Solar Probe completed its 23rd close approach to the Sun on March 22, equaling its own distance record by coming within about 3.8 million miles (6.1 million kilometers) of the solar surface. The close approach (known as perihelion) occurred at 22:42 UTC — or 6:42 p.m. EDT — with Parker Solar Probe moving 430,000 miles per hour (692,000 kilometers per hour) around the Sun, again matching its own record.

Actual science data won’t be downloaded from the spacecraft for several weeks, but it has sent back a signal that it is in good shape and operating as expected.

Webb images in the infrared the aurora of Neptune

9:30 am

The aurora of Neptune
Click for original image.

Astronomers using the Webb Space Telescope have captured the first infrared images of the aurora of Neptune, confirming that the gas giant produces this phenomenon.

The picture to the right combines infrared data from Webb and optical imagery from the Hubble Space Telescope. The white splotches near the bottom of the globe are clouds seen by Hubble. The additional white areas in the center and near the top are clouds detected by Webb, while the greenish regions to the right are aurora activity detected by Webb.

The auroral activity seen on Neptune is also noticeably different from what we are accustomed to seeing here on Earth, or even Jupiter or Saturn. Instead of being confined to the planet’s northern and southern poles, Neptune’s auroras are located at the planet’s geographic mid-latitudes — think where South America is located on Earth.

This is due to the strange nature of Neptune’s magnetic field, originally discovered by Voyager 2 in 1989, which is tilted by 47 degrees from the planet’s rotation axis. Since auroral activity is based where the magnetic fields converge into the planet’s atmosphere, Neptune’s auroras are far from its rotational poles.

The data also found that the temperature of Neptune’s upper atmosphere has cooled significantly since it was first measured by Voyager 2 in 1989, dropping by several hundred degrees.

Isar launch several times scrubbed due to high winds, rescheduled for tomorrow

9:16 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The German rocket startup Isar Aerospace, forced to scrub the first launch of its Spectrum rocket from Norway’s Andoya spaceport several times this week due to high winds, is now targeting a launch tomorrow, March 27, 2025, at 7:30 am (Eastern).

Munich-based Isar Aerospace postponed the debut launch of its Spectrum rocket, citing unfavorable winds at Norway’s Andøya Spaceport. On Tuesday, Isar said it will now target Thursday at 7:30 a.m. EDT for the highly anticipated test flight, which could pave the way for a more robust European presence in the commercial space industry.

The mission will not have a payload—rather, it will serve as the first integrated test of all rocket systems. And no matter what happens, Isar said it will view the test as a success.

…Standing about 92 feet tall with a diameter of about 6 feet, Spectrum is designed to carry payloads of up to 2,200 pounds to low Earth orbit. The two-stage vehicle burns 40 tons of liquid oxygen and propane across its nine first-stage Aquila engines and single second-stage engine. Unlike Falcon 9, though, the vehicle is not reusable, which is what allowed SpaceX to lower launch costs and take command of the market.

Isar’s goal is to eventually produce up to 40 Spectrum vehicles annually at its facility near Munich. Per Metzler, it builds nearly all components in house and is already producing two more rockets. The company is operating with about $435 million in funding from private investors as well as the NATO Innovation Fund and German government.

If successful, Isar will win the race to become the first new private rocket company from Europe to get to orbit. The launch will also inaugurate orbital operations from Andoya, giving Norway the first commercial spaceport in Europe, beating out both of the UK’s proposed spaceports that had begun work much earlier.

Survey of protoplanetary disks finds their size varies significantly

9:02 am

Proto-planetary disks of all sizes
Click for original image.

A survey of the protoplanetary disks in a star-forming region about 400 light years from Earth has found that the size of the disks can vary considerably, with many much smaller than our own solar system.

Using ALMA [Atacama Large Millimeter/submillimeter Array in Chile], the researchers imaged all known protoplanetary discs around young stars in Lupus, a star forming region located about 400 light years from Earth in the southern constellation Lupus. The survey reveals that two-thirds of the 73 discs are small, with an average radius of six astronomical units, this is about the orbit of Jupiter. The smallest disc found was only 0.6 astronomical units in radius, smaller than the orbit of Earth.

…The small discs were primarily found around low-mass stars, with a mass between 10 and 50 percent of the mass of our Sun. This is the most common type of star found in the universe.

You can read the research paper here [pdf]. The image to the right, figure 1 from the paper, shows 71 of those disks, with two-thirds clearly much smaller than our solar system.

Because exoplanet surveys have found many small exoplanets around low-mass stars, this new data suggests that planets can also form from these small accretion disks, and that planet formation is also ubiquitous throughout the universe.

NASA confirms DOGE contract cancellations totaling about $420 million

12:40 pm

According to Space News, NASA officials have now confirmed a DOGE post that described contract cancellations totaling about $420 million.

In a statement to SpaceNews late March 24, NASA press secretary Bethany Stevens confirmed a post by the Department of Government Efficiency (DOGE) that NASA had terminated about $420 million in “unneeded” contracts. “NASA is committed to optimizing its workforce and resources in alignment with the Department of Government Efficiency’s initiatives. As part of this effort, NASA has identified and phased out $420 million in contracts that were determined to be redundant or misaligned with our core mission priorities,” Stevens said in the statement.

…NASA did not answer questions about specific contracts selected for termination or details about how it determined those contracts were redundant or misaligned. The DOGE post, published just before midnight March 21, said only that it included three contracts worth $15 million each to consultancies for “Change Management Support Services.”

Though it is not yet clear what specific contracts were cancelled, the statements from both NASA and DOGE, as well as the research by Space News‘s own reporter, suggest strongly these contracts had nothing to do with space or aviation engineering, but were related to management and DEI related projects, all of which have nothing to do with NASA’s “core mission priorities.”

As always, the Space News genuflects to the swamp, implying these cuts are the precursor to the utter destruction of NASA’s science research. In truth, NASA — like all government agencies in the 21st century — is bloated and wasteful. There is plenty of room for cuts, without doing any harm to the work the agency does. If anything, by getting rid of the waste the agency will be more efficient, able to do science and engineering research more effectively.

Martian stucco

Martian stucco
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on January 24, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled simply as a “terrain sample,” it was likely taken not as part of any specific research request but to fill a gap in the schedule in order to maintain the camera’s proper temperature.

In this case the camera team got something quite intriguing. The entire terrain is reminiscent of stucco found on the outside walls of southwest homes. What makes even more intriguing is that the stucco appears to be material that has covered the terrain, based on the two craters that appear half-buried by it. Moreover, this picture only captures a small portion of this landscape, which extends like this over an area approximately 40 miles squared.

What caused this strange terrain? As always, the overview map below provides a clue, though no firm answers.

Scientists believe they have found evidence of largest carbon molecules yet in Curiosity drill sample

10:06 am

The uncertainty of science: Scientists analyzing material drilled out by the Mars rover Curiosity back in 2013 now believe the sample included the largest carbon molecules yet found on Mars.

The detection of these long and large carbon molecules was based not on actual Martian data, taken at a site dubbed Cumberland on the floor of Gale Crater, but on follow-up lab work on Earth.

The recent organic compounds discovery was a side effect of an unrelated experiment to probe Cumberland for signs of amino acids, which are the building blocks of proteins. After heating the sample twice in [the Curiosity] SAM’s oven and then measuring the mass of the molecules released, the team saw no evidence of amino acids. But they noticed that the sample released small amounts of decane, undecane, and dodecane [thought to be fragments of fatty acids].

Because these compounds could have broken off from larger molecules during heating, scientists worked backward to figure out what structures they may have come from. They hypothesized these molecules were remnants of the fatty acids undecanoic acid, dodecanoic acid, and tridecanoic acid, respectively.

The scientists tested their prediction in the lab, mixing undecanoic acid into a Mars-like clay and conducting a SAM-like experiment. After being heated, the undecanoic acid released decane, as predicted. The researchers then referenced experiments already published by other scientists to show that the undecane could have broken off from dodecanoic acid and dodecane from tridecanoic acid.

Based on this Earth lab work, the scientists now suggest that Mars could also have these much longer carbon molecules that are associated with biological processes.

Very intriguing, but we must exercise caution. Curiosity did not detect such molecules, only evidence that they might exist on Mars. And even if they do exist on Mars, this is not evidence that Mars has or once had biological life. While such large molecules on Earth are usually associated with biological processes, they do not have to be, as the scientists readily admit in their abstract. Furthermore, in the alien environment of Mars there could be many non-biological processes we don’t even yet understand that could explain their existence.

Firefly yesterday announced that it has awarded the Blue Origin subsidiary Honeybee Robotics a contract to build a rover for its third Blue Ghost mission to the Moon.

Firefly Aerospace and Honeybee Robotics, a Blue Origin company, today announced Honeybee was contracted by Firefly to provide the lunar rover for the company’s recently awarded NASA task order to explore the Gruithuisen Domes on the Moon’s near side in 2028. Once deployed on the Moon by Firefly’s Blue Ghost lander, Honeybee’s rover will carry NASA instruments to investigate the unique composition of the Gruithuisen Domes.

The funding for this rover actually comes from NASA, awarded first to Firefly which has in turn given a subcontract to Honeybee.

Before this 2028 mission however Firefly will launch its second Blue Ghost mission to the Moon, targeting a 2026 launch date. That second mission will not only land on the far side of the Moon, it will also deploy two lunar orbiters, one for European and the second Firefly’s own orbital tug for these spacecraft that will also service as a communications satellite after deployment.

ESA announces competitive program to encourage new European rocket startups

8:56 am

The European Space Agency (ESA) yesterday announced a new competitive award program, dubbed the European Launcher Challenge, designed to give contracts to new European rocket startups to help them develop their own rockets.

Proposals are due no later than May 5, 2025. The program will award up to $183 million to each company, depending on its application. The program has two components, one for rockets that will serve government contracts and will launch beginning in 2026, and the second for rockets that are upgraded by 2028. In both cases a company must complete a demonstration launch by 2027 to qualify for any award. More details here.

Essentially, ESA is structuring this program to provide free subsidies to those companies it decides it likes, with anywhere from two to three getting awards. In January six rocket startups — HyImpulse, Latitude, MaiaSpace, Orbex, Rocket Factory Augsburg and The Exploration Company — submitted a joint letter to ESA endorsing the program and outlining how they think the program should be structured.

Interestingly, the two rocket startups did not sign that letter, Isar Aerospace from Germany and PLD from Spain. Of all these companies, these two are actually closest to launch, with Isar about to attempt its first launch and PLD having already completed a suborbital test flight and building its launch sites in French Guiana and Duqm, Oman.

Officials at PLD are quoted here as apparently opposed to this ESA award program.

“We need to let the market select a winner,” Raúl Verdú, co-founder and chief business development officer of the company, said at the January conference. “Today, to be very honest, it is super-hard to select who will be the winner.”

It will be interesting to see this government program play out. Right now it appears designed to play favorites, a typical European approach. There is a good chance however that it will not do this, and will instead succeed in jumpstarting an independent, competitive European rocket industry. The program’s main structure remains sound, truly capitalistic, whereby the government owns nothing and simply acts as a customer, buying rockets from competing companies on the open market.
