SpaceX launches 26 Starlink satellites

7:18 pm

SpaceX this evening successfully placed another 26 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its fourth flight, landing on a drone ship in the Pacific.

The leaders in the 2025 launch race:

87 SpaceX
37 China
10 Rocket Lab
8 Russia

SpaceX now leads the rest of the world in successful launches, 87 to 64.

SpaceX also has another launch scheduled in just a few hours from Cape Canaveral, launching 24 Kuiper satellites for Amazon. This is SpaceX’s first launch for Amazon, out of contract of three launches. It will also be the third Kuiper satellite launch, the previous two by ULA on its Atlas-5 rocket, launching 27 satellites each.

First good image released of interstellar object 3I/Atlas as it plunges through the solar system

3:25 pm

First good image of instellator object 3I/Atlas
Click for original image of 3I/Atlas.

Astronomers using the Gemini North Telescope in Hawaii have obtained the first good image of the interstellar object 3I/Atlas, as it plunges within the orbit of Jupiter on its way through the solar system.

That picture is to the right, cropped to post here and overlaid on top of a map showing the interstellar object’s calculated path through the solar system.

The picture clearly shows this is a comet, with central nucleus surrounded by a cloud of dust and gas. The data also suggests its nucleus has a diameter of about twelve miles. That it resembles a comet also suggests it is a dirty snowball, made up of ice and rocky material mixed together.

Because it will never get closer to the Sun then just inside the orbit of Mars, it is not likely it will ever get bright enough for naked eye observations. At the same time, it is large enough and will be close enough to make possible some excellent observations as it zips by and leaves the solar system sometime in the fall. The previous two identified interstellar objects, Oumuamua and Comet 21/Borisov, were either too small or too far away as they flew past to get this kind of good data.

Another win for a blacklisted professor

2:59 pm

Professor Timothy Jackson
Music historian Timothy Jackson

Fight! Fight! Fight! After the public University of North Texas (UNT) blacklisted and dismissed professor Timothy Jackson in 2020 from his job as editor of the music history journal he founded for daring to express some academic conclusions the faculty and students didn’t like, he sued.

After a five year battle, Jackson and the university have now settled out of court, with the terms of the settlement [pdf] largely a big win for Jackson.

First the background: In 2019 woke music theorist Philip Ewell of Hunter College in New York gave a presentation to the Society of Music Theory where he claimed 20th century music theorist Heinrich Schenker was a “virulent racist” whose “racist views infected his music theoretical arguments.”

Jackson, who had devoted his career studying Schenker and had co-founded at the university the Journal of Schenkerian Studies focused expressly on Schenker’s works, knew this was patently untrue. For example, Schenker was also a Jew who was a victim of German anti-Semitism and lost many relatives in the Holocaust, facts that Ewell somehow did not think important to mention. To counter Ewell’s historical slanders, Jackson decided to dedicate the next issue of the journal to this issue, presenting essays from both sides. He even asked Ewell to write an essay.

Ewell did not respond. In Jackson’s own essay he outlined in detail the historical facts — as he knew them as an expert on this subject — that put the lie to Ewell’s claims. As Jackson noted, “Ewell peddled a ‘conspiracy theory’ that is ‘part and parcel of the much broader current of Black anti-semitism.'”

Instead of celebrating this perfect example of free speech, the university immediately moved to punish Jackson.

The failed MethaneSat climate satellite apparently had problems from launch

10:24 am

According to a detailed New Zealand news report today, the failed MethaneSat climate satellite — funded and operated by the Environmental Defense Fund — apparently had significant problems during its short fifteen month life-span, going into safe mode many times, before failing completely last month.

An earlier report from this same news outlet described more fully the issues — which began in September 2024 only about six months after launch.

The mission’s chief scientist has now said more intense solar activity because of a peak in the sun’s magnetic cycle has been causing MethaneSAT to go into safe mode. The satellite has to be carefully restarted every time.

There has also been a problem with one of the satellite’s three thrusters, which maintain its altitude and steer the spacecraft. MethaneSAT says it can operate fully on two thrusters.

It appears there is a lot of unhappiness in New Zealand for spending $32 million on this project that was designed, built, and operated by an environmental activist organization with little space experience.

What is clear now is that the spacecraft likely got relatively little data during its fifteen month life span.

Webb spots aftermath of collision of two galaxies

10:06 am

colliding galaxies
Click for source.

Using the Webb Space Telescope, astronomers have discovered the collision of two spiral galaxies that appears to have caused a supermassive black hole to collapse in its wake.

The Webb false-color infrared image to the right shows the two galaxies as the red dots, both surrounded by a ring, with the supermassive black hole the bluish spot in between but offset somewhat to the left. Follow-up radio observations suggested that this bluish spot was a supermassive black hole, having a mass of a million suns and sucking up matter from the giant gas cloud that surrounds it.

The team proposes that the black hole formed there via the direct collapse of a gas cloud – a process that may explain some of the incredibly massive black holes Webb has found in the early universe.

This hypothesis however has enormous uncertainties, and requires a lot more observations to confirm. The black hole could simply exist unrelated to the galaxy collision, having come there from elsewhere. Or it could be from a third galaxy in this group that these initial observations have not yet detected.

The image however is quite cool.

House follows Senate in canceling most of Trump’s proposed NASA budget cuts

9:45 am

Like pigs at the trough
Like pigs at the trough

The House appropriations committee’s draft budget for NASA has followed the Senate appropriations committee in canceling all of Trump’s proposed NASA budget cuts, though it has shifted that funding significantly from science to manned space operations.

The House Appropriations Committee released the draft text of their version of the FY2026 Commerce-Justice-Science bill that funds NASA today. Like their Senate counterpart, the House committee would essentially keep NASA at its current funding level instead of imposing the severe 24.3 percent budget cut proposed by the Trump Administration. The CJS bill also includes almost $2 million for a White House National Space Council even though the Trump Administration has yet to establish one.

Unlike the Senate, which mostly kept the budget the same across all NASA departments, this House draft budget would reduce science and aeronautics spending from about $8.2 billion to $6.8 billion. Trump had requested only $4.5 billion for these departments.

In turn, the House would increase Trump’s request for NASA’s manned operations from $10.8 billion to $11.9 billion. Note that Trump’s proposed budget had already called for an increase here, so the House is clearly shifting funding to manned space in an enthusiastic manner.

At the same time, the House continues funding for the SLS and Orion programs Trump wishes to cancel. Both of these projects are over budget and behind schedule. Neither is very useful in the long run for exploring the solar system. If the House truly wanted to save money, it could easily fund all the cuts in science by cutting the billions spent yearly on these pork projects, and still lower NASA’s budget in total.

Based on the draft budget’s language [pdf], it is unclear whether the House has also funded the Lunar Gateway space station, as the Senate has, another useless pork project that Trump wishes to cancel.

I should note that the appropriations committee’s overall draft budget [pdf] does reduce the federal budget by about 2.8 percent. This is a marked change from past budgets, which often claimed (a lie) to cut spending but really only reduced the rate of budget growth. It appears the House is finally making some effort to shrink the size of the budget, though that effort is quite wimpy.

Axiom’s commercial manned mission to ISS splashes down safely

8:56 am

Axiom’s fourth commercial manned mission to ISS successfully splashed down off the coast of California early this morning, returning its astronaut commander, employed by Axiom, and three government passengers from India, Poland, and Hungary after spending two weeks at the space station and eighteen days total in space.

For all three nations this was their second manned flight, and the first in more than four decades. All three had previously flown astronauts on Soviet era Soyuz missions, with Poland and Hungary’s astronauts visiting the Salyut 6 station in 1978 and 1980 respectively, and India’s astronaut visiting the Salyut 7 station in 1984.

The mission also marked the inaugural flight of SpaceX’s new Grace reusable manned Dragon capsule, the fifth such spacecraft in its fleet. SpaceX’s fleet is now larger that NASA’s space shuttle fleet ever was.

If you watch the live stream at the link, it is once again important to note that everyone you see on the screen, except for these three government astronauts, are employees of SpaceX or Axiom. There is no government involvement at all in the splash down procedure. It is entirely commercial and private affair.

In other words, who needs NASA for spaceflight? It clearly is not required.

A distant globular cluster

10:03 am

A distant globular cluster
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 research project to study globular clusters in galaxies other than the Milky Way.

The data for this image comes from an observing programme comparing old globular clusters in nearby dwarf galaxies — the LMC [Large Magellanic Cloud], the Small Magellanic Cloud and the Fornax dwarf spheroidal galaxy — to the globular clusters in the Milky Way galaxy. Our galaxy contains over 150 of these old, spherical collections of tightly-bound stars, which have been studied in depth — especially with Hubble Space Telescope images like this one, which show them in previously-unattainable detail. Being very stable and long-lived, they act as galactic time capsules, preserving stars from the earliest stages of a galaxy’s formation.

Astronomers once thought that the stars in a globular cluster all formed together at about the same time, but study of the old globular clusters in our galaxy has uncovered multiple populations of stars with different ages. In order to use globular clusters as historical markers, we must understand how they form and where these stars of varying ages come from. This observing programme examined old globular clusters like NGC 1786 [pictured] in these external galaxies to see if they, too, contain multiple populations of stars. This research can tell us more not only about how the LMC was originally formed, but the Milky Way Galaxy, too.

This cluster, discovered in 1835 by John Herschel, is about 160,000 light years away.

Third Indian state announces a space policy to encourage private enterprise

9:37 am

India map

A third state in India, Andhra Pradesh, has now released its own space policy, designed to create what it calls “manufacturing clusters”, centered around India’s main spaceport at Sriharikota.

The A.P. Space Policy (4.0) 2025-30 is valid for five years from the date of issue (July 13, 2025), or till a new policy is announced. A technical committee will be constituted under the Commissioner of Industries to vet and process applications for land allotment in the Space Cities proposed to be developed along the Hyderabad-Bengaluru Industrial Corridor in Sri Sathya Sai district and in Tirupati (Routhasuramala).

The government will form an SPV, ‘AP Space City Corporation’, which will drive all initiatives related to the development of the above Space Cities, and serve as the central agency to coordinate infrastructure development, raise start-up funds, attract investments, facilitate industry partnerships, build partnerships to attract global demand, and liaise with all GoI [Government of India] entities for tapping the domestic demand.

The previous two state space policies in Tamil Nadu and Gujarat, announced in April, had similar goals aimed at promoting the establishment of private aerospace companies within their regions.

Whether Andhra Pradesh’s policy will work carries uncertainties. Its advantage is that it is linked to India’s primary spaceport. Its disadvantage lies in the complex bureaucracy the state is creating in conjunction with these “Space Cities.” Such bureaucracies are rarely helpful for new businesses.

LIGO detects gravitational waves of largest black hole merger yet

9:22 am

The LIGO gravitational wave detector, spread across several continents, successfully detected the largest black hole merger yet on November 23, 2023.

The two black holes that merged were approximately 100 and 140 times the mass of the Sun. In addition to their high masses they are also rapidly spinning, making this a uniquely challenging signal to interpret and suggesting the possibility of a complex formation history. “This is the most massive black hole binary we’ve observed through gravitational waves, and it presents a real challenge to our understanding of black hole formation,” says Professor Mark Hannam, from Cardiff University and a member of the LIGO Scientific Collaboration. “Black holes this massive are forbidden through standard stellar evolution models. One possibility is that the two black holes in this binary formed through earlier mergers of smaller black holes.”

To date, approximately 300 black-hole mergers have been observed through gravitational waves, including candidates identified in the ongoing O4 run. Until now the most massive confirmed black-hole binary was the source of GW190521, with a much smaller total mass of “only” 140 times that of the sun.

As noted by the press release as well as this news article, present theories of stellar evolution say that these black holes could not have come from single stars, which are predicted to never be this massive. It is posited that each black hole might have formed from earlier mergers, but there is also a lot of uncertainty in the data. To quote the release again: “Extracting accurate information from the signal required the use of theoretical models that account for the complex dynamics of highly spinning black holes.”

That this detection was almost two years ago and only announced now makes me wonder if the timing of the announcement has more to do with lobbying and less to do with science. Trump’s proposed budget eliminates the U.S. funding portion for this project, and it is standard operating procedure for such projects to suddenly announce big discoveries timed to correspond to when Congress is considering the budget.

Suborbital test launch from Oman’s Duqm spaceport scrubbed

9:09 am

The Middle East, showing the location of
Oman’s proposed spaceport at Duqm.

A suborbital test launch from Oman’s Duqm spaceport was scrubbed yesterday due to” a technical issue” with the rocket.

DUQM: Etlaq Spaceport’s highly anticipated experimental rocket launch mission “Duqm-2” was aborted due to a technical issue on Sunday, July 13, 2025. Consequently, the launch has been postponed until “a replacement solution is developed,” it stated.

This was the second attempt launch scrubbed at Duqm, officially labeled the Etlaq Spaceport. The first, an attempt by a Middle East startup to do a vertical take-off and landing of a prototype small rocket, was scrubbed in April due to weather and technical issues. No new launch date has been scheduled.

The spaceport had announced in April a schedule of five launches before the end of the year. Two have now been scrubbed. All appear to have major financing from the Oman government. I suspect all have been pushed too hard and too fast by the government for PR reasons, which explains the two scrubs and the lack of a new launch schedule.

Dragon capsule undocks from ISS carrying four Axiom’s passengers

8:47 am

After spending 18 days in space, 14 on ISS, the Dragon capsule early this morning undocked from ISS with a splashdown scheduled for early tomorrow.

The mission was financed by the space station company Axiom, and was commanded by former NASA astronaut Peggy Whitson, now employed by Axiom as a professional astronaut. The three paying passengers were all government astronauts from India, Poland, and Hungary.

The capsule, dubbed Grace, is the newest addition to SpaceX’s fleet of five manned reusable capsules, flying on its first mission.

Splashdown is scheduled for the wee hours of July 15th tomorrow off the coast of California. The live stream can be found here.

Judge narrows SpaceX lawsuit against California Coastal Commission

9:16 am

Though U.S. district judge Stanley Blumenfeld ruled in May that SpaceX’s lawsuit against California Coastal Commission for targeting the company because the commissioners did not like Elon Musk’s political views can proceed, in early July he also narrowed the lawsuit significantly.

Blumenfeld granted a motion to dismiss violations of the First Amendment and due process against the commission and individual members based on lack of standing, sovereign immunity and failure to state a claim, but allowed allegations of “biased attempts to regulate SpaceX’s activity” and unlawfully demanding a CDP to proceed.

“In sum, SpaceX has plausibly alleged a ripe, nonspeculative case or controversy over whether it must obtain a CDP to continue its Falcon 9 launches,” Blumenfeld said in his order. “The credible threat that defendants will bring an enforcement action and subject SpaceX to daily fines for not having a CDP — which defendants pointedly do not disavow — is sufficient to establish an actual injury under Article III [of the U.S. Constitution].”

It appears the judge acted to protect the commissioners themselves from direct liability, using the made-up concept from the 20th century that government employees are somehow wholly immune from any responsibility for their actions.

Nonetheless, SpaceX has a great case, and is very likely to win in court, a victory that could very well cause the coastal commission and the state of California serious monetary pain.

First suborbital launch of Taiwan rocket startup fails

9:06 am

The first suborbital launch of the Taiwan rocket startup Tispace failed today shortly after lift-off from a new commercial spaceport on the northern island of Hokkaido in Japan.

The rocket took off from Hokkaido Space Port at 11:40 a.m. local time, but it was soon seen drifting, with smoke escaping. Footage of the launch was shown by NHK News on its website.

Nobody was reported injured in the incident, and the rocket was not carrying any payload. The first launch of a foreign-made rocket from Hokkaido served to test its engine’s capabilities, the report said.

The rocket startup was formed in 2016 and originally wanted to launch from Taiwan. After legal issues blocked that launch site it then attempted to arrange a launch from Australia. It appears similar red tape issues forced it to switch to Japan.

Weird drainages on Mars

Weird drainages on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on Februay 11, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team posted it yesterday as their own cool image, labeling it “A Fissure and Channel near Pavonis Mons”. From the caption:

A linear trough strikes northeast, then abruptly ends (or changes into a narrow ridge). Where the trough ends, a sinuous channel has an east-southeast strike, trending at almost a right angle to the trough. What happened to form these features?

We can speculate that first there was a southwest-to-northeast trending fracture or fault, perhaps associated with a volcanic vent. Groundwater (or some other runny fluid) coursed through the fault until overflowing and forming the sinuous channel. Continued movement through the fault carved a trough up to the overflow point.

The arrows indicate the downhill grades. Though this caption mentions groundwater, it is far more likely that the “runny fluid” was lava, as shown by the overview map below.

Senate committee moves to cancel most of Trump’s proposed NASA budget cuts

9:03 am

Like pigs at the trough
Like pigs at the trough

We’ll just print it! Though disagreements prevented the Senate’s appropriations committee from approving the 2026 bills covering the commerce, justice, and science agencies of the federal government (including NASA) , the committee yesterday appeared poised to cancel most of Trump’s proposed NASA budget cuts and even add more spending across the board.

Sen. Chris Van Hollen (D-Maryland), the top Democrat on the CJS subcommittee, said this morning the bill would fund NASA at $24.9 billion, slightly above its current $24.8 billion level, with the Science Mission Directorate (SMD) remaining level at $7.3 billion.

By contrast, the Trump Administration wants to cut NASA overall by $6 billion, from $24.8 billion to $18.8 billion. SMD’s portion would drop 47 percent, from $7.3 billion to $3.9 billion.

The disagreements centered not on NASA, but on the Trump administration’s effort to cancel a very expensive new FBI headquarters building in the Maryland suburbs and instead shift the agency to an already existing building in DC. Van Hollen opposed this, and the ensuing political maneuvering forced the committee to cancel the vote.

This bill would once again continue full funding for SLS, Orion, and Lunar Gateway. It also includes funding for NASA’s very messed-up Mars Sample Return mission (which comprises the large bulk of the money added back in for science). From this it appears that the Republicans in the Senate are quite willing to join the Democrats in spending money wildly, as they have for decades. They have no interest in gaining some control over the out-of-control federal budget, in any way, as Trump is attempting to do.

What remains unknown is this: Who has the support of the American people? The election suggests the public agrees with Trump. History suggests that this support for cutting the budget is actually very shallow, and that while the public says it wants that budget brought under control, it refuses to accept any specific cuts to any program. “Cut the budget, but don’t you dare cut the programs I like!”

It is my sense that the public’s view is changing, and it is now quite ready to allow big cuts across the board. The problem is that the vested interests in Congress and in the DC work force are quite powerful, and appear to still control the actions of our corrupt elected officials.

Thus, the more of that work force that Trump can eliminate as quickly as possible, on his own, the more chance he will have to eventually bring this budget under some control.

Varda raises another $187 million in private investment capital

8:41 am

The in-space manufacturing startup Varda has now raised another $187 million in private investment capital, bringing the total cash the company has raised to $329 million.

The $187 million fundraise was led by Natural Capital and Shrug Capital, with participation from Founders Fund, Peter Thiel, Khosla Ventures, Caffeinated Capital, Lux Capital, and Also Capital. Since launching their first mission, W-1, in 2023, Varda has completed three successful launch and return missions, with a fourth, W-4, currently in orbit and a fifth expected to launch before the end of the year.

…”With this capital, Varda will continue to increase our flight cadence and build out the pharmaceutical lab that will deliver the world’s first microgravity-enabled drug formulation,” said Varda CEO Will Bruey.

Varda has expanded its footprint terrestrially as well, opening an office in Huntsville, Ala. and a new 10,000 square foot laboratory space in El Segundo, which will allow its pharmaceutical scientists to begin working on developing processes to crystallize biologics, such as monoclonal antibodies. As of 2022, the market size for monoclonal antibodies is estimated to be $210.06 billion.

As I have noted previously, a real market for pharmaceuticals produced in weightlessness has existed for decades. It appears Varda is now well placed to be the first to make money doing so, using its returnable capsules.

One more note: These products and this industry could have been developed on ISS, but NASA has banned all profit-making commercial manufacturing projects there from the station’s beginning. You can do research, but you are forbidden to create any products for sale later on Earth. This strange policy is left over from before the station, when Reagan discontinued all commercial missions on the shuttle following the Challenger accident.

  • On this day in 1962 AT&T launched the first private satellite, Telstar-1
    It demonstrated relatively inexpensive broadcast and communication between Europe and North America. AT&T’s plan then was to launch a full constellation to provide phone and broadcast service worldwide, replacing the expensive and very limited undersea cables. The plan ended up getting blocked by Congress and President Kennedy, who instead created a monopoly run by the pseudo-company Comsat, partly owned by the government. While Comsat launched a number of geosynchronous satellites, it never came close to the success promised.

    Had the government stayed out, we would have had large satellite constellations in the early 1960s and a robust private launch industry. Instead, it all died on the vine, and it would be more than a half century before the American commercial space industry recovered.

Another scientist blacklisted by the Biden CDC ends up in charge

2:56 pm

Martin Kulldorff, no longer blacklisted
Martin Kulldorff, no longer blacklisted

Fight! Fight! Fight! When Trump appointed Jay Bhattacharya, the director of Stanford University’s Center for Demography and Economics of Health and Aging, to head the National Institutes of Health (NIH) a few weeks after his election victory in November, I immediately noted that this choice “underlined quite forcefully the certainty that the outsider nature of all of Trump’s picks to head all the health-related agencies in the federal government will led to major changes in how those agencies operate.”

Bhattacharya had been blacklisted for his very vocal opposition to the government’s lockdown and mandate policies during the COVID epidemic. He along with Martin Kulldorff, one of the world’s foremost experts on vaccines and who was also blacklisted during the epidemic, co-authored the Great Barrington Declaration that strongly criticized the policies imposed by these health agencies, calling instead for a return to the standard response to infectious diseases that had been followed successfully for more than a century.

Putting Bhattacharya in charge of NIH is incredibly ironic. When he along with Kulldorff had come out opposed to the lockdown and jab mandates advocated by Francis Collins, then-head of the NIH, Collins in league with Anthony Fauci, then head of National Institute of Allergy and Infectious Diseases (NIAID), put together a back-room campaign to have Bhattacharya, Kulldorff, and many others blacklisted across social media. This campaign also had Kulldorff removed as a member of the CDC’s vaccine safety advisory committee.

My prediction that the outside nature of Trump’s appointments was going to signal major changes continues to hold true, and was further underlined with the announcement on June 29, 2025 that Kulldorff has now been re-appointed to the CDC’s vaccine advisory board as part of the major house-cleaning that Health Secretary Robert Kennedy Jr. announced in early June, when he removed all seventeen members of the board.

SpaceX gets approval to build oxygen plant at Boca Chica

1:03 pm

SpaceX today received the okay from Cameron County to build a plant at Boca Chica to produce oxygen from the atmosphere for use in its Superheavy/Starship rocket.

The commissioners voted, 3-1, to give Elon Musk’s rocket company a beachfront construction certificate and dune protection permit, allowing the company to build a modern-day factory akin to an oil refinery to produce gases needed for space flight launches.

The plant will consist of 20 structures on 1.66 acres. The enclosed site will include a tower that will reach 159 feet, or about 15 stories high, much shorter than the nearby launch tower, which stretches 480 feet high. It is set to be built about 280 feet inland from the line of vegetation, which is where the dunes begin. The factory will separate air into nitrogen and oxygen. SpaceX utilizes liquid oxygen as a propellant and liquid nitrogen for testing and operations.

By having the facility on site, SpaceX hopes to make the delivery of those gases more efficient by eliminating the need to have dozens of trucks deliver them from Brownsville. The company says they need more than 200 trucks of liquid nitrogen and oxygen delivered for each launch, a SpaceX engineer told the county during a meeting last week.

As usual, the same cranks who always complain about this stuff are given space by this news outlet to whine, but the truth is that the commission’s vote well reflects the attitude of the local community. It supports what SpaceX is doing, because of the prosperity the company is bringing to this formerly depressed region.

Moreover, this facility will not only save SpaceX money and make it easier to launch more frequently, it is likely environmentally beneficial. I suspect the facility will be relatively clean compared to the truck convoys it will replace.

Why did Trump suddenly pick Transportation Secretary Sean Duffy to become temporary head of NASA?

9:32 am

The reason for Trump’s sudden decision yesterday to name Transportation Secretary Sean Duffy as interim NASA administrator, replacing long-time NASA manager Janet Piro — who had held the job since Trump took office — remains unclear.

This article suggests the president wanted someone with more political clout who was also part of his inner circle.

Two articles (here and here) imply the decision was related to the recent clashes politically between Trump and Musk, adding that Duffy and Musk have been reported to be in conflict over air traffic controller issues. Picking Duffy thus directly reduces Musk’s influence at NASA.

The truth is that we really don’t know exactly what motives brought Trump to make this appointment. It could be that Trump wants someone in charge who will have the political clout to push through his proposed NASA cuts. It also could be Trump wants someone with that clout to review those cuts and change them.

The bottom line is that NASA remains a political football, a situation that in the end had done decades of harm to the American space industry. The sooner it can be made irrelevant and replaced by a commercial, competitive, and (most important) profitable space industry, the better.

We really don’t need a “space agency.” We didn’t have such a thing when we settled the American west.

SpaceX finally passes final regulatory hurdle to sell Starlink in India

9:11 am

You might get deja-vu from this story, since I have reported repeatedly in the past that SpaceX has finally gotten regulatory approval to sell Starlink in India.

However, India’s complex regulatory framework — leftover from the days of British rule and strengthened for decades after independence when the strongly socialist Congress Party ruled — ended up requiring SpaceX to leap multiple regulatory hurdles to get the Starlink approved. According to news reports today, that last licensing hurdle has now finally been leaped.

The final approval marks a crucial milestone that will pave the way for the Musk-led company to launch its commercial satellite operations in the country. The Elon Musk-led company has been waiting for regulatory approvals since 2022 to operate legally in India. With this approval, Starlink has become the third company to enter the satellite space in India after Reliance Jio and Eutelsat’s OneWeb, in which Bharti Airtel, led by Sunil Mittal, is a shareholder.

Does this mean SpaceX can now sell Starlink in India? Of course not:

The next step for Starlink is to secure spectrum from the government, which will likely be assigned in the coming months. It also needs to set up infrastructure on the ground. One of the most critical aspects of Starlink’s India foray will be its compliance with the country’s security rules.

Since Starlink doesn’t need a complex ground infrastructure, selling terminals directly to customers, the infrastructure mentioned in the quote likely involves partnering Starlink operations with the Indian telecommunications companies Airtell and Jio, so that they get a piece of the action.

New census of inverted channels on Mars strongly suggests the planet once had more water

A new review of inverted channels on Mars now strongly suggests that the red planet was once far wetter than presently seen, with the channels implying the existence of liquid rivers.

The discovery of more than 15,000 kilometres of ancient riverbeds on Mars suggests that the Red Planet may once have been much wetter than previously thought. Researchers looked at fluvial sinuous ridges, also known as inverted channels, across Noachis Terra – a region in Mars’ southern highlands. These are believed to have formed when sediment deposited by rivers hardened and was later exposed as the surrounding material eroded.

Similar ridges have been found across a range of terrains on Mars. Their presence suggests that flowing water was once widespread in this region of Mars, with precipitation being the most likely source of this water.

The image to the right is a good example of an inverted channel, a previous cool image posted in April 2025. It is located not in Noachis Terra but in the northern lowland plains.

The researchers argue that these channels suggest that about 3.7 billion years ago there were flowing liquid rivers on Mars, fed by precipitation. This conclusion however still does not explain how this could happen on a planet that is too cold with too thin an atmosphere for liquid water to exist. Every model so far proposed to make Mars warmer with a thicker atmosphere in the distant past remains questionable with many holes.

Could the inverted channels have been created by glacial activity, ice instead of liquid water? At present we don’t know enough about the Mars environment and the physics of such things in the planet’s one-third gravity to answer that question. It is however a question that scientists I think should be asking, based on the extensive evidence of glacial activity in the Martian mid-latitudes.

The big takeaway from this study however is that it adds weight to the overall trend seen in the data, that over time the total amount of water on the planet has declined. We can see this in glaciers, for example, with later glacial flows always falling short of previous flows. This research shows that even in the dry tropics there was once ample water, even if we don’t yet know what form it took.
