Poland fires head of its space agency

10:29 am

Apparently due to his failures in min-February dealing with debris dropped on Poland from a de-orbiting Falcon 9 upper station, the government has fired the head of its space agency.

The President of the Polish Space Agency, Grzegorz Wrochna, has been dismissed following a botched response to the uncontrolled re-entry of a Falcon 9 second stage that scattered debris across multiple locations in Poland.

It appears Wrochna’s office had sent its reports on the debris to the wrong email address, so that the people higher up in the command chain were not informed properly about what was happening. This failure was then compounded in early March when the space agency’s computer systems were hacked, forcing it to shut down its access to the internet.

You might ask why Poland even has a space agency, and if you do you are asking the right question. The nation does not have “a space program,” which would require an agency. Instead it has a handful of new rocket startups, mostly focused on suborbital flights. All these need is the right legal framework to succeed, not a bureaucracy telling them what to do.

Europe’s Hera probe to fly past Mars tomorrow

10:22 am

As part of its journey to the binary asteroid Didymos/Dimorphos, the European Space Agency’s (ESA) Hera probe will slingshot past Mars tomorrow, obtaining images and data of both the red planet and its moon Deimos.

Three instruments will gather data, a navigational camera, and infrared camera, and a spectral camera, with the goal mostly to calibrate the instruments and make sure they are working as designed. The data won’t be available until the next day, when the ESA will hold a webcast unveiling the images.

NASA shuts down three unneeded departments, including its DEI office

10:06 am

NASA this week began complying with Trump’s executive orders by finally shutting down its DEI office as well as two other unneeded departments.

NASA’s Office of Technology, Policy and Strategy; the Office of the Chief Scientist; and the Diversity, Equity, Inclusion and Accessibility branch in the Office of Diversity and Equal Opportunity will be shuttered, in compliance with Trump’s executive order, “Implementing the President’s Department of Government Efficiency Workforce Optimization Initiative.”

A total of 23 employees were laid off. All three offices were established during the Biden administration, and provided no real value to the agency. The first two merely gave advice to top management, advice unneeded if the right people are put in charge. The third agency, DEI, was worse than unneeded, because it shifted the agency’s focus from good engineering and space exploration to favoring some races over others in hiring and promotions.

In fact, the DEI office had already been neutered prior to this week’s layoffs, based on the nature of NASA press releases in the past two months. Prior to Trump taking office, almost every single NASA press release touting the work of one or more of its employees would be entirely focused on the race or ethnicity of that employee, with almost every profile featuring a woman or minority. White men need not apply.

Since January 20, 2025, the range of employees featured in these profiles has changed radically. While minorities and women have been profiled, their race and gender is no longer mentioned. Instead, the releases tout their experience, skills, and talent. More important, the releases have now stopped blacklisting white men (who actually make up a majority of NASA’s workforce), highlighting many new and long term such individuals in just the past three weeks. The change has been quite refreshing.

Meanwhile, most of the propaganda press has been lying about these layoffs, attempting to paint them as a major disaster that will destroy NASA’s ability to accomplish anything in the future, with the worse example this headline from the science journal Nature: “NASA begins mass firings of scientists ahead of Trump team’s deadline”. That headline is a total lie. This was certainly not a “mass firing” and no space scientist was fired. Of those let go from the first two offices, all were managers, one of whom was also a “climate scientist”, not a space researcher.

More layoffs are expected of course under Trump’s campaign to shrink the federal government. If later layoffs follow the pattern of this first one, they will likely improve NASA’s workforce, eliminating the fat so that what remains can be more focused on what needs to be done.

SpaceX officials provide cause of loss Falcon 9 first stage after successful landing

9:45 am

The damaged Falcon 9 booster laying on its side
on its drone ship as it returns to port.

At a press conference yesterday, SpaceX officials outlined the results of its investigation into the loss of Falcon 9 first stage when it fell over on its drone ship shortly after a successful landing.

Speaking at a news conference following a flight readiness review for the Crew-10 mission to the International Space Station, Bill Gerstenmaier, vice president of Build and Flight Reliability at SpaceX, said about 85 seconds into the launch of the Starlink 12-20 mission, there was a fuel leak in the first stage booster, tail number B1086, and kerosene sprayed onto a hot component of the engine. He said that caused it to vaporize and become flammable.

Because there wasn’t enough oxygen to interact with the leaked fuel, it didn’t catch fire during the ascent, he said. But about 45 seconds after B1086 landed on their droneship, ‘Just Read the Instructions,’ there was enough oxygen available to get into the engine compartment and a fire broke out. “It subsequently blew out the barrel panel on the side of the rocket, just like it was designed to. The fire was all contained in the engine compartment,” Gerstenmaier said. “Even if we would’ve had a problem during ascent, this shows that the fire and the damage would be contained in just a single engine out, which still allows us to accomplish the entire mission.”

The company is still working to determine the cause of the leak itself.

Though the article and video at the link make a big deal about the FAA grounding SpaceX’s Falcon 9 fleet, the agency’s actions here were quite trivial compared to its behavior when Biden was president. It grounded the fleet for only a few days, while SpaceX did its initial investigation, and then immediately accepted the above conclusions from SpaceX and lifted the grounding, even though the company has not yet determined the leak’s cause.

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.

Space Force awards development contracts to eight startups

9:27 am

The Space Force’s commercial office, dubbed SpaceWERX, announced March 8, 2025 that it has awarded development contracts to eight startups totaling $440 million.

Each STRATFI agreement is worth up to $60 million, with SpaceWERX and several defense agencies contributing up to $30 million per project. Private investors provide matching funds to scale innovations that have already demonstrated viability through prototype development.

The winners — Albedo, Beast Code, CesiumAstro, Gravitics, LeoLabs, Rise8, Umbra and Xona — were announced March 8 at an event at the Capital Factory in Austin, Texas.

Of these companies, Gravitics is probably the most interesting, as it is attempting to become a major American provider of space station modules. It already has a $125 million contract with Axiom to build a small module for that company’s station. This new contract from the Space Force suggests the Pentagon is considering launching its own space station, or possibly attaching a Gravitics module to one of the four private stations presently being built. Below is my present ranking of these four stations:

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for a 30 day mission. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS. There are rumors it is experiencing cash flow issues, but it is also going to do a fourth ISS tourist flight this spring, carrying passengers from India, Hungary, and Poland.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Though Blue Origin has apparently done little, Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building the station’s modules for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman. It recently had its station design approved by NASA.

Blue Ghost activates NASA drill, prepares for hot lunar noon

9:16 am

Map of lunar landing sites
Landing sites for both Firefly’s Blue Ghost and
Ispace’s Resilience

More than a week after landing in Mare Crisium, ground controllers have prepared Firefly’s Blue Ghost lunar lander for surviving the very hot lunar noon while also activating NASA’s LISTER drill, which proceeded to successfully drill down into the lunar surface below the lander.

Mounted below Blue Ghost’s lower deck, NASA’s Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) payload is a pneumatic, gas-powered drill developed by Texas Tech University and Honeybee Robotics that measures the temperature and flow of heat from the Moon’s interior.

I have embedded below the video of this drilling operation. At this moment it appears that nine of the lander’s payloads have completed their tasks successfully, with no indication yet that the tenth playload will have problems. All in all, Firefly has succeeded in establishing itself now as the leading private company capable of launching spacecraft to other worlds.

Expect no end, no slowdown, in Trump’s non-stop offensive

1:41 pm

Trump defiant after being shot
Trump defiant

For those like me who have been around for awhile, the present Trump administration is truly remarkable in that it harks back to an old, very fundamental American military strategy established by Ulysses S. Grant: Never stop your offensive, not for one instant.

When Grant won a battle he didn’t rest on his laurels. He immediately pushed forward because he knew he had his enemy on the run and at its weakest. When he lost a battle (which almost never happened) he didn’t pull back to lick his wounds, but instead re-configured his forces to push forward nonetheless, knowing that his victorious enemy was likely unprepared for a new assault.

Eisenhower demonstrated his understanding of this strategy during the Battle of the Bulge in December 1944. The Germans had surprised the Allies with their offensive, and thus had successfully pushed a major westward prong splitting Eisenhower’s forces in two. Rather than retreat, however, Eisenhower immediately went on the offensive, moving to pinch off that salient from the north and south and thus trap the German army behind enemy lines. That strategy ended up defeating the Germans, forcing them either to surrender or retreat.

This Trump administration is different from all other Republican presidents, including Trump’s first term, in that he is following this basic winning military strategy, keeping the pressure up continuously, with an enthusiasm that is breath-taking. » Read more

Blue Ghost landed almost dead center within its target zone

10:55 am

Blue Ghost on the Moon
Click for before and after blink animation

The picture to the right, taken by Lunar Reconnaissance Orbiter (LRO) prior to the successful landing of Firefly’s Blue Ghost lunar lander, shows its entire landing region. The inset in the lower left is a picture taken by LRO on March 3, 2025, after landing.

The full picture was taken near sunset, with sunlight coming from the left. The inset was taken at sunrise, with sunlight coming from the right. This explains the difference in shadows between the two. Blue Ghost is the white dot in the inset with its long shadow, the black streak, cutting through the nearby crater. The first picture taken from the lander after landing looked down that shadow, looking across the crater.

The new picture tells us that Blue Ghost landed almost dead center in its target zone, indicating that the engineering worked as planned. The lander also used its computer brain to pick a good landing spot and avoid the nearby craters.

A galactic ball and spiral interact

A galactic ball and spiral interact
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a study of the star populations in these two interacting galaxies. From the caption:

Arp 105 is a dazzling ongoing merger between an elliptical galaxy and a spiral galaxy drawn together by gravity, characterized by a long, drawn out tidal tail of stars and gas more than 362,000 light-years long. The immense tail, which extends beyond this image from NASA’s Hubble Space Telescope, was pulled from the two galaxies by their gravitational interactions and is embedded with star clusters and dwarf galaxies.

The three blue objects on the outskirts of both galaxies are thought to be active star-forming regions. Whether all three are part of this collision is unclear, as the object on the lower right might simply be a foreground object based on the available data.

What makes this galactic pair so intriguing is that the two galaxies are so different with very different theorized histories. Elliptical galaxies (“the ball”) are thought to be very old, the result of the long term evolution of spirals. You would therefore not think an elliptical would normally interact with a spiral, as their ages are likely so dissimilar.

Anonymous sources: Starship will need a major rebuild after two consecutive failures

9:38 am

Starship just before loss of signal
Starship just before loss of signal on March 6, 2025

According to information at this tweet from anonymous sources, parts of Starship will likely require a major redesign due to the spacecraft’s break-up shortly after stage separation on its last two test flights.

These are the key take-aways, most of which focus on the redesign of the first version of Starship (V1) to create the V2 that flew unsuccessfully on those flights:

  • Hot separation also aggravates the situation in the compartment.
  • Not related to the flames from the Super Heavy during the booster turn.
  • This is a fundamental miscalculation in the design of the Starship V2 and the engine section.
  • The fuel lines, wiring for the engines and the power unit will be urgently redone.
  • The fate of S35 and S36 is still unclear. Either revision or scrap.
  • For the next ships, some processes may be paused in production until a decision on the design is made.
  • The team was rushed with fixes for S34, hence the nervous start. There was no need to rush.
  • The fixes will take much longer than 4-6 weeks.
  • Comprehensive ground testing with long-term fire tests is needed. [emphasis mine]

It must be emphasized that this information comes from leaks from anonymous sources, and could be significantly incorrect. It does however fit the circumstances, and suggests that the next test flight will not occur in April but will be delayed for an unknown period beyond.

I think the tweet however is much too pessimistic. If the problems are all within the fuel lines, engine wiring, and the power unit, they are well localized. Moreover, the design of these components on version 1 of Starship apparently worked reasonably well, which gives them a good basis for that redesign. Nonetheless, if these facts are correct, my guess is the next test flight won’t occur before June.

The one saving grace is that FAA red tape is clearly no longer an additional obstacle. It is very clear now that with the change from Biden to Trump it is letting SpaceX lead all investigations, and immediately accepting its conclusions and fixes, rather than sitting on those conclusions as it retyped them for weeks or months in its own report.

After a decade of development, ESA finally starts testing a part of its Callisto grasshopper

9:12 am

Callisto's basic design
Callisto’s basic design

My heart be still! First proposed in 2015 as Europe’s answer to SpaceX’s Falcon 9, the European Space Agency, in partnership with Japan, has finally begun acoustical testing of just one part of its Callisto grasshopper-type reusable test prototype, as shown on the right.

Callisto consists of five main sections: the Aft Bay, which includes the engine and landing legs, the LH2 Tank, the LOx Tank, the VEB, and the Fairing. The VEB houses much of the demonstrator’s electronics, including its onboard computer, avionics, and a reaction control system that uses H2O2 propellant. Its distinctive features include a pair of control fins.

In addition to confirming that the VEB had been transported to the CNES facilities in Toulouse, the 4 March Institute of Space Systems update also revealed that the acoustic test campaign for the key Callisto module had commenced last week. The acoustic test campaign simulates the intense sound vibrations the demonstrator will experience during flight to ensure structural integrity and component reliability.

The whole project has a budget of $100 million. The first test hop won’t occur until 2026, eleven years after the project began, and six years behind its original launch date. In that same time, SpaceX has completed several hundred commercial landings of its Falcon 9 first stage, reusing those stages up to two dozen times.

Nor is Callisto part of any program to develop a similar reusable rocket. It is a typical dead-end government project, with ESA having no clear goal to apply it commercially. The best Europe can hope for is that the engineering lessons from its tests will be given freely to the new European commercial rocket startups, so that they can use it someday.

Space Force’s X-37B completes seventh flight, lasting 434 days

8:22 am

With landing on March 7, 2025 at Vandenberg in California, of one of the Space Force’s two X-37B reusable mini-shuttles, the military completed the seventh total flight, this one lasting over 434 days.

The mission achieved a number of important milestones. First, it was the first launched on SpaceX’s Falcon Heavy rocket. Previously launches had used both ULA’s Atlas-5 as well as SpaceX’s Falcon 9.

Second, the spacecraft successfully demonstrated its ability to use aerobraking to adjust its orbit.

The Space Force also claimed other classified experiments on board “tested space domain awareness technology experiments that aim to improve the United States Space Force’s knowledge of the space environment.” That’s however all they told us.

Because the Space Force has stopped telling us which of the two X-37B’s is flying on each launch, it is not clear the Space Force even has a fleet of two any longer. It could be one has been retired.

Intuitive Machines confirms Athena fell over at landing; ends mission

1:33 pm

Athena on its side on the Moon

Artist rendering of lander on Moon

Intuitive Machines today officially ended its Athena lunar lander mission after it released a picture taken from the top of the lander showing clearly that it had fallen over on its side after landing.

That picture, cropped, reduced, and brightened to post here, is to the right. You can clearly see two of the landing legs in the air, with the horizon in the background.

“With the direction of the sun, the orientation of the solar panels, and extreme cold temperatures in the crater, Intuitive Machines does not expect Athena to recharge,” the company stated. “The mission has concluded and teams are continuing to assess the data collected throughout the mission.”

This is the second Intuitive Machines lunar lander to tip over. More and more it does appear that the tall design of this lander is fundamentally flawed. The artist rendering to the right illustrates this. Most unmanned lunar landers are much wider than they are tall. Intuitive Machines’ Nova design has the lander’s height matching the spread of its legs. It creates a center of gravity high enough that the lander will tip over too easily if conditions are not perfect.

The company denies this, saying the center of gravity is much lower than this graphic makes it appear, but the proof is in the pudding. Their design has tried to land on the Moon twice, and both times the lander tipped over.

It is not clear what the company can do to fix this. Expanding its diameter to lower its height is a major redesign. It also might make the lander too wide to fit inside most rocket fairings. A better solution might be to redesign the legs, making their spread wider, and even increasing their number.

Fortunately, NASA’s shift to capitalism in space has produced a number of different companies building lunar landers. Firefly’s Blue Ghost is clearly a success. In June Ispace will make its second attempt to soft land its private lander design on the Moon. And Astrobotic has a contract to try again after it had a fuel line leak after launch last year that prevented it from even attempting a landing.

And of course, Intuitive Machines is still in the game. It has a contract for one more landing mission, plus a mission to put two data relay satellites in lunar orbit.

India’s Vikram lunar lander: Data suggests there could be more water impregnated in more places on the Moon

12:16 pm

According to scientists analyzing the data sent back from India’s Vikram lunar lander, it appears that water could be impregnated in the upper lunar soil in more places than previously predicted.

You can read their paper here [pdf]. One instrument on the lander measured the temperature of the soil down about four inches, and found the temperature to be 25 degrees Celsius warmer than expected. That location was on a sunward-facing slope, so it was expected to be warmer but not by that amount. From the paper’s abstract:

This demonstrates that local topography at metre scales can alter temperature at high latitudes, unlike equatorial regions. Numerical model calculations using ChaSTE measurements, suggest that larger poleward facing slopes(>14°) at high latitudes can harbour water-ice, making them promising and technically less challenging sites for future lunar exploration and habitation.

In other words, slopes that get much less sunlight near the poles but are not permanently shadowed could still be cold enough only a few inches below the surface to harbor water molecules.

Sounds good, but I am beginning to sense a bit of blarney in these stories, over-pushing the possible existence of water to encourage more government space funding. It might be true that there is more water molecules in more places than predicted, but rarely do these reports say how much, which I expect will be very very little, in the parts per billion range. Nor do these stories ever consider the processing necessary to extract that water. Based on other data obtained from the Shadowcam instrument on South Korea’s Danuri lunar orbiter, it increasingly seems to me that any water found in polar regions of the Moon could be very slight, or even if in large amounts much more difficult to access than anyone ever mentions.

Once again the leftist propaganda press takes out its knives to stab SpaceX and Musk

11:18 am

Superheavy captured safely by the chopsticks, for the third time in four attempts
Superheavy captured safely yesterday by the chopsticks,
for the third time in four attempts

As should be expected, the destruction of Starship yesterday just before it made orbit on its eighth test flight was immediately used by partisan leftist media outlets to play “Let’s beat up on SpaceX and Elon Musk because he’s a friend of Trump!”

All these outlets decided to emphasize the falling debris and disruption to air traffic, but in doing so they all spun the story in a very dishonest way. First, both SpaceX and the FAA had been prepared for this possibility, and had used well-established procedures — in league with all other involved nations — to respond to the launch failure. The air space was cleared for only about fifteen minutes, as only this Florida Today article noted. Take-off delays at affected airports ranged from minutes to almost an hour, but hardly much different that normal delays seen every day.

Most important, no one was hurt, no planes were damaged, and there were no negative consequences. If anything, yesterday’s Starship flight illustrated the competence shown by SpaceX as it runs a very ambitious and radical development program of the most powerful rocket ever built. For example, why so little mention of the successful catch of Superheavy, something SpaceX has been able to do three times in the first four test flights? That achievement is truly mind-blowing.

The obviousness of these attacks is truly getting tedious. Moreover, why the hostility to one of the most spectacular efforts by an American company? Shouldn’t the American news outlets above be enthused by this effort? Have they become so hateful of their own country in all things, they want it to fail, always?

Sadly, I think we know the answer to that last question. The leftist indoctrination effort that now dominates almost all of America’s universities has produced a generation that does hate America, because they literally know nothing of its history except the distorted lies put forth by these Marxist colleges. They would rather destroy success than have America succeed.

It is both tragic and shameful, and a perfect example of someone cutting off their own nose to spite their face.

French official lauds Ariane 6 launch; demands Europe have its own launch capability

10:08 am

Philippe Baptiste, France’s Minister for Higher Education and Research, yesterday loudly touted the second successful launch of Ariane 6 rocket, even though it occurred years late and costs far more than any other rocket on the market today.

Baptiste did so even as he insisted the Europe must continue to have its own launch capability so that it need not depend on rockets from other countries.

Europe must have sovereignty in space and “not yield to the temptation of preferring SpaceX or another competitor that may seem trendier, more reliable, or cheaper,” Baptiste [said]. “This first commercial launch of Ariane 6 is not just a technical and one-off success. It marks a new milestone, essential in the choice of European space independence and sovereignty. In the labyrinth of the global space race, Ariane 6 is the guiding thread of our strategic autonomy for the years to come.

“We must also collectively advance, as Europeans, on the governance of Europe’s space ambitions. We must ask ourselves all the questions, without taboos. For Europe in space, I am convinced that the European Union must fully assume its role as the political leader in this matter. The challenges are immense, no one knows this better than we do.”

Note Baptiste’s focus on having the European Union (EU) run things, with a focus on Ariane-6, despite its high cost. He was previously head of France’s space agency CNES, which for years has used the EU and the European Space Agency’s (ESA) partners help pay for France’s space program by requiring that all rocket launches be run by ESA’s commercial division, Arianespace.

That situation is now changing, with other ESA nations (Germany, Italy, Spain, and the United Kingdom) all breaking free from Arianespace and instead encouraging the development of competing private rocket startups independent of ESA or Arianespace. Moreover, these ESA partners have aggressive reduced Arianespace’s areas of control. It no longer runs the French Guiana spaceport. Its management of the Vega-C rocket has been transferred back to the Italian company Avio, which builds it. All it now has is Ariane-6, which has limited value because it is so expensive.

So while Baptiste desire for European autonomy matches the efforts of these European countries, his apparent desire to keep all control within the continent’s centralized government authority has been rejected. Europe has a chance to compete, but only because it is freeing its rocket startups from government control.

Webb captures infrared view of a baby binary star system and its bi-polar jets

9:41 am

A baby binary in formation
Click for original image.

Cool image time! The infrared false-color picture to the right, reduced and sharpened to post here, was released today by the science team of the Webb Space Telescope. It shows the bi-polar jets spewing out from a newly formed binary of two very young stars as their interact during their formation process.

The two protostars responsible for this scene are at the center of the hourglass shape, in an opaque horizontal disk of cold gas and dust that fits within a single pixel. Much farther out, above and below the flattened disk where dust is thinner, the bright light from the stars shines through the gas and dust, forming large semi-transparent orange cones.

It’s equally important to notice where the stars’ light is blocked — look for the exceptionally dark, wide V-shapes offset by 90 degrees from the orange cones. These areas may look like there is no material, but it’s actually where the surrounding dust is the densest, and little starlight penetrates it. If you look carefully at these areas, Webb’s sensitive NIRCam (Near-Infrared Camera) has picked up distant stars as muted orange pinpoints behind this dust. Where the view is free of obscuring dust, stars shine brightly in white and blue.

To put it more simply, the accretion disk for the binary system lies at right angles to the much larger jets. The rotation of that disk as well as the stars causes those jets to flow up and down from the poles, with the existence of two stars producing the complex patterns in those jets.

As this image was focused mostly on studying the upper jet, it does not show the entire lower jet, which extends beyond the lower border.

Today’s eighth orbital test flight of SpaceX’s Starship/Superheavy giant rocket has turned out to be almost identical to the seventh flight, with Superheavy completing its mission with a perfect chopstick catch at the launch tower in Boca Chica and Starship failing just before engine shutdown that would have put it into its orbit.

The screen capture to the right shows that moment. Note that graphic on the far lower right. It indicates that only two of the outside engines are firing, in an asymmetrical configuration. As a result Starship began tumbling, as shown by the fact that the Earth is not visible in the background. Shortly thereafter contact was lost, and I expect the flight termination system took over to destroy the ship. Expect videos from the Caribbean of it burning up overhead in the next day or so.

Superheavy however completed the third ever capture by the launch tower chopsticks. Musk has indicated that the company is pushing to reuse a Superheavy booster as soon as possible. The lose of Starship and the fact that two Superheavy engines shut down prematurely during the boost-back burn after stage separation likely delays that reuse at least one or two test flights. First, this Superheavy had issues, that might be solvable but they nonetheless exist.

More important, the loss of Starship just before its orbital coast once again means SpaceX was unable to do any of its orbital and return test program. It will not make sense to risk the next Starship flight with a used Superheavy when testing Starship has now been delayed twice.

Nor does it matter much. It will take many more launches before this rocket is reliably reusable. The first priority now is to make it more reliable on its first launches. Expect SpaceX to target the next test flight for sometime in mid- to-late April.

Athena sits at an unknown angle on the Moon, hampering operations

Athena's landing site 100 miles from the Moon's south pole
Yellow cross indicates Athena’s targeted landing site

According to the CEO of Intuitive Machines, Athena is sitting an an unknown angle on the Moon, impacting the possibility of all surface science operations.

The tilt is hampering their ability to use the high gain antenna which they need use to download most of their data. They do not know the angle, or the cause of this issue. It could simply be that the ground slope is too severe. It is also possible the spacecraft, which has a relatively high center of gravity, fell over on its side because of that slope. Moreover, they do not know at the moment exactly where the spacecraft landed, though they know it landed on Mons Mouton as planned. They need to download pictures from the spacecraft, as well as from Lunar Reconnaissance Orbiter (LRO) in orbit to determine precisely the location and the situation.

It is also unclear what payloads will be impacted by this situation. It could be that most if all could be utilized, but that question cannot be answered until they learn more. I suspect both the mini-rover and the Grace hopper will be affected the most, as the tilt might make it impossible to deploy either.

For Intuitive Machines this situation is very unfortunate. It has sent two unmanned lunar landers, and both have had issues at landing, though it must be emphasized that the issue on today’s second landing might have nothing to do with the company’s engineering at all.

Is a supermassive black hole is hidden in the Large Magellanic Cloud?

11:45 am

Based on the motions of a number of runaway stars on the edge of the Milky Way that are moving so fast they will leave the galaxy, astronomers believe that many were accelerated not by the galaxy’s own central supermassive black hole but a previously undetected supermassive black hole at the center of the Large Magellanic Cloud, one of the Milky Ways nearby dwarf galaxies.

To make this discovery, researchers traced the paths with ultra-fine precision of 21 stars on the outskirts of the Milky Way. These stars are traveling so fast that they will escape the gravitational clutches of the Milky Way or any nearby galaxy. Astronomers refer to these as “hypervelocity” stars.

Similar to how forensic experts recreate the origin of a bullet based on its trajectory, researchers determined where these hypervelocity stars come from. They found that about half are linked to the supermassive black hole at the center of the Milky Way. However, the other half originated from somewhere else: a previously-unknown giant black hole in the Large Magellanic Cloud (LMC).

You can read the paper here [pdf]. This result was made possible by the very precise location and velocity data of over a billion stars measured by Europe’s Gaia satellite.

Based on the available data, the scientists estimate (with great uncertainty) the mass of this supermassive black hole, which the scientists have dubbed LMC* (pronounced “LMC star”), to be about 600,000 times the mass of the Sun, quite big but significantly less than the mass of the Milky Way’s central black hole, Sagittarius A* (pronounced “A-star”), which is estimated to be about 4.3 million times the mass of the Sun.

The mystery to solve now is why this super massive black hole is so quiet. It has literally emitted no obvious energy in any wavelength in the past seven decades, since ground- and space-based telescopes went into operation capable of detecting such emissions. Even the relatively inactive supermassive black hole at the Milky Way’s center, Sagittarius A* (pronounced “A-star”) emits distinct radio energy that the first radio telescopes were able to detect almost immediately.

Intuitive Machines’ Athena lander touches down softly; engineers are assessing spacecraft condition

10:55 am

Though Intuitive Machines’ Athena lander has apparently softly landed near the south pole of the Moon, there remains uncertainty about the spacecraft’s status. Engineers have contact with Athena, and are apparently shutting down the landing equipment in order to make Athena safe for surface operations.

Unlike the previous landing, the spacecraft is upright and responding fully as expected. It appears the main issue is the position of Athena relative to the horizon. This is important as it determines the best antenna’s to use to upload and download data to and from Earth.

A full update will be provided at a press conference scheduled for 4 pm (Eastern) today. I have embedded the live stream of that conference below.

Scientists discover the oldest known crater on Earth

10:09 am

Though erosion has made it visibly unnoticeable now, scientists have discovered geological features 3.5 billion years old in northwestern Australia that suggest the location is the oldest impact crater known on Earth.

The crater was discovered by geologists at Curtin University and the Geological Survey of Western Australia in the Pilbara region of northwestern Australia. While it’s hard to see directly as a classic crater shape, due to its age, the team found it through other evidence – namely “shatter cones,” geological features that form only when exposed to extreme pressures, like meteorite impacts or underground nuclear explosions.

The newly discovered crater is estimated to be at least 100 km (62 miles) wide, which suggests the original object that crashed into Earth was traveling at more than 36,000 km/h (22,000 mph), and would have caused destruction on a global scale. The impact appears to have occurred 3.47 billion years ago. “Before our discovery, the oldest impact crater was 2.2 billion years old, so this is by far the oldest known crater ever found on Earth,” said Professor Tim Johnson, co-lead author of the study.

You can read the published paper here. There are many assumptions and uncertainty in this conclusion, but it is likely correct.

The impact likely occurred during a time period scientists call the Late Heavy Bombardment, when the planets in the solar system were beginning to accrete out of the thick disk of dust and rocks that surrounded the Sun. On Earth most of the evidence of this bombardment is gone, destroyed by erosion and plate technoics. We only know about it from the craters on the Moon, Mercury, and Mars, where erosion has left those impacts mostly untouched.
