China launches another technology test communications satellite payload

10:52 pm

China today successfully launched a test technology satellite for doing “multi-band and high-speed communication technology validation tests, possibly for future large internet/communications constellations, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No word on where the rocket’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2025 launch race:

40 SpaceX
19 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 40 to 33.

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

2:48 pm

Jared Isaacman
Jared Isaacman

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

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

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

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

Overview map
Click for interactive map.

Cool image time! The Curiosity science team has finally completed the rover’s climb up one canyon on the flanks of Mount Sharp and crossed over into a second, switch-backing up through a gap they have dubbed Devil’s Gate.

The panorama above, created from three pictures taken by Curiosity’s left navigation camera on April 9, 2025 (here, here, and here) looks south from that gap. On the horizon about 20-30 miles away can be seen the rim of Gale Crater. From this position the floor of the crater is almost out of side, blocked by the foothills on the lower flanks of Mount Sharp.

Though the ground in this new canyon (on the left of the panorama) continues to be amazingly rocky and boulder strewn, it is actually more benign that the canyon Curiosity has been climbing for the past six weeks.

The blue dot on the overview map to the right marks Curiosity’s present position, with the yellow lines indicating the approximate direction of the panorama. The rover’s next major geological goal is the boxwork to the southwest. In order to get to it quickly the science team decided to abandon its original planned route, indicated by the dotted red line, and climb upward through these canyons.

Chinese scientists say the lunar far side appears drier than the near side

10:17 am

Map of water measurements of lunar samples
Click for original image.

Based on a comparison of samples brought back by two Chinese unmanned lunar landers, Chinese scientists believe the lunar far side contains far less water in its mantle than the near side.

…the research team focused on analyzing water content and hydrogen isotopes in melt inclusions and apatite within [Chang’e-6] mare basalts—the first samples returned from the farside SPA Basin.

The team’s results indicate that the parent magma of these basalts contain 15–168 μg.g⁻¹ of water. Additionally, the team estimated that the mantle source of the CE6 basalts has a water content of 1–1.5 μg.g⁻¹, significantly lower than that of the nearside mantle. This disparity points to a potential hemispheric dichotomy in the Moon’s internal water distribution, mirroring many of the asymmetrical features observed on the lunar surface.

The map to the right, figure 1 in the scientists’ paper, shows the water content from the samples that have so far been brought back from the Moon. Note how the Chang’e-6 sample shows far less water content than all the near side samples.

Note however also that this is just one data point from the far side. To confirm these conclusions will require many more samples.

Lunar Outpost unveils its proposed “Eagle” manned lunar rover

9:41 am

In the bidding competition to win the full NASA contract to build the manned lunar rover the astronauts will use in the Artemis program, the startup Lunar Outpost this week unveiled its proposed “Eagle” manned lunar rover at a conference in Colorado.

In the configuration shown here at the symposium, the Eagle vehicle features two seats for crew, each with its own redundant and mirrored controls, meaning either astronaut can control the rover. The steering controls on each side consist of a single handle that controls four individual motors that drive each wheel. Each wheel can turn independently of the other three, allowing the Eagle rover to turn on its center axis or “crab walk” sideways, Gerner said.

The rover can also be operated unmanned remotely, providing an method for sending it places the astronauts might prefer to avoid, for safety reasons.

Lunar Outpost is competing with Intuitive Machines and Venturi Astrolab for the main contract.

Anti-Musk terrorists damage Musk statue in Brownsville

9:23 am

In another demonstration of their intolerance and willingness to commit violence and vandalism, anti-Musk terrorists have damaged a bust of Elon Musk in Brownsville that had been placed there by a French entrepreneur.

A 9-foot-tall statue depicting a bust of tech billionaire Elon Musk has been vandalized in South Texas. According to multiple posts across social media, the statue of the SpaceX CEO was vandalized not far from where the company’s Starbase facility sits near Boca Chica Beach.

“The recently installed Elon Musk statue, known as ‘Elonrwa,’ has been damaged. Visible patches of the outer layer appear to have been peeled off the face,” a Facebook user who goes by RGV.me said in an April 8 Facebook post. The Facebook post is accompanied by a photograph showing two areas where it appears a top layer of material has been stripped from the statue, revealing a white or pale gray layer underneath.

This senseless hate of Musk, almost certainly committed by supporters of the Democratic Party — which has been encouraging this violence because it sees Musk as an opponent — must end. And if the fools perpetrating this vandalism don’t come to their senses and stop voluntarily, they should be stopped by force and imprisonment. Just because you disagree with someone on policy does not give you the right to break the law.

And if you doubt this vandalism isn’t being spurred on eagerly by the leadership of the now vile and wholly evil Democratic Party, you need only watch that party’s Senate leader, Senator Charles Schumer (D-New York), practically endorse it when asked:

Juno enters and then recovers from safe mode

9:03 am

During its most recent close fly-by of Jupiter on April 4, 2025 — its 71st — the orbiter Juno went into safe mode two different times, causing its science instruments to shut down.

The mission operations team has reestablished high-rate data transmission with Juno, and the spacecraft is currently conducting flight software diagnostics.The team will work in the ensuing days to transmit the engineering and science data collected before and after the safe-mode events to Earth.

Juno first entered safe mode at 5:17 a.m. EDT, about an hour before its 71st close passage of Jupiter — called perijove. It went into safe mode again 45 minutes after perijove. During both safe-mode events, the spacecraft performed exactly as designed, rebooting its computer, turning off nonessential functions, and pointing its antenna toward Earth for communication.

Since arrival in its present Jupiter orbit in 2016 Juno has operated almost perfectly, having experienced only two other safe mode events, once in 2016 and a second in 2022. The two recent events on this most recent fly-by suggest however that the harsh environment surrounding Jupiter might be beginning to impact the spacecraft.

Isaacman’s nomination hearing reveals nothing of note

10:00 am

Jared Isaacman
Jared Isaacman

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

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

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

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

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

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

Firefly wins Space Force contract to test orbital maneuvers with its Elytra space tug

12:33 pm

Firefly yesterday announced it has been awarded a Space Force contract to use its Elytra space tug to test orbital maneuvers designed for military purposes.

As part of the mission, Elytra will host a suite of government payloads, including optical visible and infrared cameras, a responsive navigation unit, and a universal electrical bus with a payload interface module. Firefly’s Elytra Dawn configuration will utilize common components from the company’s launch vehicles and lunar landers, including the avionics, composite structures, and propulsion systems, to enable on-demand mobility, plane changes, and maneuvers with high delta-V capabilities and reliability.

Though unstated, the inclusion of cameras suggests the Pentagon wants to test Elytra’s ability to maneuver close to other satellites and photograph them.

This contract further illustrates Firefly’s effort to diversify its space products. Like Rocket Lab, it is not relying solely on its rocket division to make money, but is also developing and selling a range of space products, from lunar landers to orbital tugs to satellite equipment.

Astronomers: Potentially dangerous asteroid 2024 YR4 originally came from main asteroid belt

12:26 pm

Using new data from ground-based telescopes, astronomers now believe that the potentially dangerous asteroid 2024 YR4 originally came from main asteroid belt and is a stony solid body, not a rubble pile.

The study reveals YR4 is a solid, stony type that likely originated from an asteroid family in the central Main Belt between Mars and Jupiter, a region not previously known to produce Earth-crossing asteroids. “YR4 spins once every 20 minutes, rotates in a retrograde direction, has a flattened, irregular shape, and is the density of solid rock,” said Bryce Bolin, research scientist with Eureka Scientific and lead author of the study.

You can read the paper here [pdf].

At present calculations suggest it has an almost zero chance of hitting the Earth in 2032, though during that close approach the chances of it hitting the Moon range from 2% to 4%, depending on which scientist you ask.

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

8:52 am

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

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

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

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

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

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

Space Force gives SpaceX launch originally contracted to ULA

8:45 am

For the second time in less than a year, the Space Force has taken a launch away from ULA and given the payload to SpaceX to launch.

The GPS III SV-08 satellite, the eighth in the GPS III constellation, is now scheduled to launch no earlier than late May aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station, Florida, the Space Systems Command announced April 7.

This marks the second time in recent months that the Space Force has reassigned a GPS launch from ULA to SpaceX. Last year, the GPS III SV-07 satellite was moved from a planned ULA Vulcan rocket launch in late 2025 to a SpaceX Falcon 9, which successfully launched on December 16 in a mission called Rapid Response Trailblazer.

Both switches were apparently triggered because of the delay in getting ULA’s new Vulcan rocket certified by the military, resulting in all of ULA’s launches in 2025 being pushed back significantly. That certification finally occurred a few weeks ago, but it appears the Space Force has decided that ULA won’t be able to get all those launches off this year as planned. It therefore decided to shift this launch to SpaceX.

This situation once again highlights the importance of private companies to move fast in the open competition of private enterprise. SpaceX has always done this, and thus it gets contracts and business that other companies that move with the speed of molasses lose.

Bangladesh signs Artemis Accords

8:37 am

Bangladesh today became the 54th nation to sign the Artemeis Accords, and the first to do so during Donald Trump’s second term.

The full list of nations now part of this American space alliance: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

Based on NASA’s press release, it appears that Trump has not yet addressed the changes created by the Biden administration to the accords’ basic goals. The release still touts the accords as being “grounded in the Outer Space Treaty,” as if the accords were created to strengthen that treaty.

This is exactly the opposite of the accords’ original goals. Trump initiated the Artemis Accords as a way to create a large international alliance strong enough to either force changes in the Outer Space Treaty’s limitations on private property, or to bypass it completely.

At some point in the next three years, expect Trump’s eye to turn to the accords, and demand changes to the Outer Space Treaty. And don’t expect those demands to be mild and gentle. Right now the Outer Space Treaty forbids any nation from claiming any territory on the Moon, Mars, or the asteroids, thus forbidding western nations that believe in private property and citizens’ rights from establishing their legal law there. Either that limitation is going to be removed, or Trump is going to use the combined strength of the Artemis Accords alliance to bypass it entirely.

SpaceX launches 27 more Starlink satellites using a new first stage

8:16 pm

SpaceX today successfully placed 27 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its first flight, landing on a drone ship in the Pacific. In the past three years SpaceX has been launching about one to two new first stages per year in order to sustain its fleet, and this launch follows that pattern.

The leaders in the 2025 launch race:

40 SpaceX
18 China
5 Rocket Lab
4 Russia (with a manned Soyuz launch scheduled for the early morning hours)

SpaceX now leads the rest of the world in successful launches, 40 to 31.

The mighty scale of Mars’ geology

12:16 pm

The mighty scale of Mars
Click for original image.

Today’s cool image is just one more example out of hundreds I have posted in the past decade of the difficult-to-imagine gigantic scale of the Martian landscape.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on March 1, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The image title is simple, “Steep Slopes of Olympus Mons Caldera,” and tells us that this cliff face, about 1,300 feet high, is part of the caldera that resides on top of Mars’ largest volcano, Olympus Mons.

The parallel cracks on the plateau above the cliff tell us that the cliff face is slowly separating outward from that plateau, and that at some point in the future the entire wall will collapse downward.

Sounds impressive and big, eh? What the picture doesn’t make clear however is how truly tiny this cliff is in the context of the entire mountain.

Soil bacterium from Earth can both make and repair bricks made from Moon-materials

9:36 am

Researchers in India have now discovered that the same soil bacterium from Earth they used to manufacture bricks made from Moon-materials can also act to repair cracks in those bricks.

A few years ago, researchers at the Department of Mechanical Engineering (ME), IISc developed a technique that uses a soil bacterium called Sporosarcina pasteurii to build bricks out of lunar and Martian soil simulants. The bacterium converts urea and calcium into calcium carbonate crystals that, along with guar gum, glue the soil particles together to create brick-like materials. This process is an eco-friendly and low-cost alternative to using cement.

… In a new study, they created different types of artificial defects in sintered bricks and poured a slurry made from S. pasteurii, guar gum, and lunar soil simulant into them. Over a few days, the slurry penetrated into the defects and the bacterium produced calcium carbonate, which filled them up. The bacterium also produced biopolymers which acted as adhesives that strongly bound the soil particles together with the residual brick structure, thereby recovering much of the brick’s lost strength. This process can stave off the need to replace damaged bricks with new ones, extending the lifespan of built structures.

These results are encouraging but not necessarily for space exploration. This research can likely be applied with great profit here on Earth to repair damaged materials already in place.

As for using it in space or on the Moon, great uncertainties remain, such is whether the bacteria could even survive or function in a different gravity environment. The team hopes to test this on one of India’s planned Gangayaan manned missions.

British MP proposes his government’s vast bureaucratic skills be given the power to regulate all space

9:25 am

“We’re here to help you!” George Freeman, a British MP who was also its minister for science, research, technology and innovation under two previous Tory governments, has now proposed that Great Britain’s great skill at bureaucracy (which has done a great job bankrupting both rocket companies and spaceports) be given the job as the world’s regulatory cop.

Freeman said as space minister he had focused on UK leadership in space regulation, insurance and finance; convening the industry partnership with the UK space sector and Lloyds of London to create the Earth∞Space Sustainability Initiative (ESSI), which aims to set global standards for the sector, and securing the backing of Canada, Japan and Switzerland through the global summit at the Royal Society. “The idea of my space debris regulation and the creation of the Earth Space Sustainability Initiative was very simple,” he said.

… But it isn’t only in the field of satellite technology where regulation will be important. From crewed missions to Mars to the prospect of lunar mining and even creating data centres on the moon, the opportunities space offers are myriad. Regulations around space debris, Freeman said, could act as a gateway to rules in other areas.

“It can gradually evolve,” the MP explained. “You could imagine, say, on space traffic control, that you wouldn’t get permission to launch from aviation authorities unless you’ve got a licence to operate. Licence to operate says you must be compliant with basic standards.

This concluding quote at the link, written by the reliably naive pro-government leftist British outlet The Guardian, says it all:

Freeman added the UK is well placed to lead on such matters. “Space needs a global regulatory alliance led by and headquartered in a trusted nation. You need a country that’s got a long and distinguished history as a trusted partner, a long, 300-year role as a regulator of choice, that believes in and is respected internationally for its legal system and is connected to financial market and international courts and jurisdiction,” he said.

“This is a huge opportunity for the UK. We should seize it.”

The UK red tape this blowhard admires so much — and likely helped create — caused Virgin Orbit to go bankrupt while it waited for months to get a launch license. It has also practically destroyed the business at two UK spaceports because the paperwork makes launching there so burdensome. Rocket companies are going elsewhere for this reason.

The worst thing we could do is give Freeman and the bankrupt regulatory culture he helped create the power to establish similar regulations for the rest of the world. The entire newly-born space industry that is bursting out everywhere would choke to death almost immediately.

Fram2: The first X-ray image taken in space

9:04 am

First X-ray taken in space
Click for original.

During the commercial and private Fram2 flight last week, the crew used equipment developed by two commercial companies, MinXray in Chicago and KA Imaging in Canada, to take the first X-ray images of a human being.

The picture to the right shows the hand of one of the crew, with a ring on one finger. From the press release:

Chicago-based MinXray is contributing its IMPACT system, a compact, battery-powered X-ray generator designed for use in remote environments, including space. Its rechargeable lithium-ion battery eliminates the need for external power sources, making it an ideal solution for microgravity applications.

KA Imaging’s Reveal 35C X-ray Detector was selected for this mission due to its cutting-edge SpectralDR technology. The Reveal 35C provides dual-energy subtraction imaging in a single exposure, generating three distinct images: soft tissue, bone, and a traditional digital radiograph.

Apparently the two companies have combined their resources to develop a fully portable X-ray machine small enough to be transported in a capsule, and partnered with the Fram2 team to test it in weightlessness for the first time. With refinements a larger machine could be sold and installed in space stations for both medical research as well as simple doctoring.

Because weightlessness causes the loss of bone density in the weight-bearing bones, such technology has long been critically necessary in orbit for studying and possible mitigating that problem. That after decades NASA failed to get it built and installed in ISS, yet a private mission made it happen, illustrates once again the advantages of a free and competitive private sector in space. NASA’s complex rules for getting experiments on ISS frequently acts to block some experiments. The lack of those rules on private missions allows for things to happen quickly.

Space Force awards SpaceX, ULA, and Blue Origin $13.7 billion in launch contracts

10:41 am

The Space Force yesterday awarded a combined $13.7 billion in launch contracts to SpaceX, ULA, and Blue Origin, covering military launches through 2032.

The contracts, announced April 4 by the U.S. Space Force’s Space Systems Command, are part of the National Security Space Launch (NSSL) Phase 3 Lane 2 procurement, a cornerstone initiative designed to bolster the Pentagon’s access to space for its most sensitive and risk-averse missions.

SpaceX emerged as the leading contractor, securing $5.9 billion in anticipated awards, followed by ULA at nearly $5.4 billion and Blue Origin at nearly $2.4 billion. The three companies are expected to collectively perform 54 launches under the agreement between fiscal years 2025 and 2029.

Based on the contracts, SpaceX will do 28 launches, ULA 19, and Blue Origin 7. Since these launches include many military payloads that must go on “risk-adverse” rockets, the distribution of launches makes sense. While SpaceX’s rockets (Falcon 9 and Falcon Heavy) are well proven to be reliable, both ULA and Blue Origin launch with new rockets, Vulcan and New Glenn respectively, that have barely yet left the factory. Vulcan has done only two launches, with the second having technical issues (supposedly resolved). Blue Origin has done only one successful launch, though it failed to land the first stage as planned.

The distribution however serves the needs of both the military and the American rocket industry. It gives the Pentagon redundancy, multiple launch providers. And it gives America the same, three competing rocket companies striving for business and profit.

The result is going to be a very vibrant American space effort, doing a lot of things having nothing to do with the Pentagon.
