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

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

9:00 am

Martian ridges that imitate rivers
Click for original image.

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.

Sightseeing near Starship’s candidate Martian landing sites

An interesting mesa near Starship's Martian landing zone
Click for original image.

Today’s cool image takes us sightseeing in the region on Mars that SpaceX has chosen for its prime landing zone for its Starship spaceship. The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 29, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a 465-foot-high unusually shaped mesa in this region.

The full resolution inset at the bottom of the picture focuses at the strange tilted layers on the southern slope of this mesa. Apparently the layers at this spot were pushed sideways so they lie significantly angled to the horizontal. Though it isn’t clear from this picture, it is possible that the mesa itself is made up of similar tilted layers, hidden below the surface. We can see the tilt only on the mesa’s southern flank because erosion has apparently exposed it.

Note also the black stain that surrounds the mesa. Though this might be caused by wind distributing dust, such stains have also been seen at a location where scientists suspect an inactive hot spring might exist, as well as another location where there may have been relatively recent volcanic activity.

Is this stain caused by any of these processes? In situ exploration would probably be necessary to find out. And we may soon actually have spaceships landing here in the relatively near future with the capability to do this.

The walls of Jericho blocking Trump’s effort to streamline government have now fallen

Trump defiant after being shot
Trump defiant

Fight! Fight! Fight! The Supreme Court ruling yesterday that allowed Trump’s plan to reorganize and reduce the federal workforce to go forward was far more significant than most realize. It in fact tells us that opposition to Trump’s effort is dissolving, and that he will have the ability in the last three years of his present term in office to complete this effort in a manner that will reshape the federal bureaucracy in ways so radical we will not recognize it when he is done — assuming Trump maintains his present aggressive effort.

First the background. In February Trump issued an executive order requiring agency managements throughout the executive branch to institute plans for reducing staffing signficiantly.

Titled “Implementing The President’s ‘Department of Government Efficiency’ Workforce Optimization Initiative,” the executive order also severely limits federal departments’ ability to bring on more staffers and mandates that agency heads closely coordinate with their DOGE representatives on future hiring plans. Once the hiring freeze that Trump put in place is lifted, agencies will only be allowed to replace one of every four employees who leave and hiring will be restricted to the highest-need areas.

Plus, agencies will not be able to fill vacancies for career positions that DOGE team leaders think should remain open, unless the department head determines they should be filled. DOGE leaders at each agency will file a monthly hiring report to DOGE.

Not surprisingly numerous lawsuits were immediately filed to block this order, claiming that Trump was required to get Congressional approval for such actions.

Coalition of space companies begs Congress to fund office designed to track satellites

9:54 am

A coalition of 450 space companies has now submitted letters to both the House and Senate begging Congress to not kill the funding for an office in NOAA created during the first Trump administration and designed to help manage satellite traffic in orbit.

A coalition of space industry associations representing hundreds of companies is urging Congress to reject Trump Administration plans to kill the nascent Traffic Coordination System for Space (TraCSS). Developed through NOAA’s Office of Space Commerce, TraCSS began beta testing last fall to provide data to civil and commercial satellite operators to avoid collisions. Just as the system is finally taking shape, it is targeted for elimination in the FY2026 budget request. The Senate Appropriations Committee takes up that proposal on Thursday when it marks up the Commerce-Justice-Science (CJS) bill that includes NOAA.

This new office was first conceived as a replacement for the tracking that the U.S. military has been doing since Sputnik was launched in 1957, information that it provides free to the industry. It appears Trump in his second administration has now concluded this new NOAA office is essentially redundant and therefore unnecessary.

The letters to the House [pdf] and Senate [pdf] urge Congress to reinstate the $65 million in spending for this NOAA office, but offer no suggestions on what to cut to fund this extra cost. Instead, like all such lobbying efforts, it expects Congress to simply print money to pay for the expense.

Meanwhile, it remains a valid question why this additional office is needed if the military has been doing the job quite successfully for the last three-quarters of a century. The letters argue this is a job better suited to a civil agency, but why? The military has to do it anyway for security reasons. Why waste money on a duplicate effort?

ESA tests parachutes and guidance system for its proposed Space Rider reusable mini-shuttle

9:38 am

The engineering
Click for original image.

The European Space Agency (ESA) revealed today that it has completed drop tests from a helicopter of an engineering vehicle of its proposed Space Rider reusable mini-shuttle — similar in concept to the U.S. military’s X-37B — testing the spacecraft’s parachutes and re-entry guidance system.

The drop-test campaign had two objectives: the qualification of the parachutes used to slow the spacecraft during descent, and to test the software that controls the parafoil, guiding the Space Rider’s reentry module to its precise landing site. Space Rider models were dropped from a CH-47 Chinook Italian Army helicopter from altitudes ranging from 1 to 2.5 km, at the Italian military’s training and experimentation area Salto di Quirra.

The press release provides no movie of any of the drop tests, and the images it provides are almost all taken from very far away, making it impossible to see in detail what the engineering vehicle looks like. Only one picture clearly shows it, and that is what I have posted to the right. This is not a model of a spacecraft, but a square box carrying the parachutes and sensors.

Note also that ESA was doing similar drop tests last summer of a similar model. Apparently they aren’t yet ready to test the real thing.

This X-37B copy was first tested by ESA in 2015 and by 2017 the agency was promising it would be flying commercially by 2025. A decade later and they have not yet begun testing a full scale spacecraft. In addition, ESA has established some very complex rules about who can use it commercially, rules so complex I predict few will be interested.

Europe might be trying to adopt capitalism and freedom as its model, but in many ways it behaves as if it hasn’t the foggiest idea what it is doing.

ISRO successfully tests thrusters to be used on its manned Gaganyaan capsule

9:14 am

India’s space agency ISRO last week successfully completed two tests of the attitude control thrusters that will be used on its manned Gaganyaan capsule.

In a statement issued on Wednesday, ISRO said that the short-duration tests, lasting 30 seconds and 100 seconds respectively, were aimed at validating the test article configuration. The space agency stated that the overall performance of the propulsion system during the hot tests had been normal and aligned with pre-test predictions.

It was also noted that during the 100-second test, the simultaneous operation of all Reaction Control System (RCS) thrusters in various modes—both steady state and pulsed—along with all Liquid Apogee Motor (LAM) engines had been successfully demonstrated.

The first unmanned test flight of Gaganyaan is presently targeting a launch in the last quarter of 2025, with two more unmanned test flights in 2026. The manned mission of one to three days would follow in 2027.

Fight! Fight! Fight! A Houston pediatrician, Christina Propst, has now been fired because she expressed glee that some Texans might die in this week’s flash floods there because Texas had the nerve to vote for Trump in the 2024 election.

Her exact words:

May all visitors, children, non-MAGA voters and pets be safe and dry.
Kerr County MAGA voted to gut FEMA.
They deny climate change.
May they get what they voted for.
Bless their hearts.

The implication was that she really didn’t care that some kids died as well. She hates Trump that much.

This is not the attitude a health organization wants from its pediatricians, whose job it is to treat children. Within hours her employer, Blue Fish Pediatrics, suspended her, then quickly followed up by firing her.

Canadian rocket startup hopes to fly first suborbital launch from its proposed Newfoundland spaceport in August

9:43 am

Nordspace's proposed spaceport
Nordspace’s proposed spaceport. Click for original.

Though details remain slim, the Canadian rocket startup Nordspace now says it is targeting an August launch of its hopes to fly first suborbital launch from its proposed spaceport in August.

NordSpace’s Taiga rocket isn’t going to reach orbit when it launches in August, but it’s a big step toward the company’s ultimate goal. Taiga is a small, liquid-fueled, hypersonic launch vehicle capable of carrying just over 110 pounds (50 kilograms) above the Karman Line. This summer’s shakedown cruise will be a low-altitude demonstration of Taiga’s capabilities.

The map to the right indicates the location of the spaceport, near the town of St. Lawrence on the southern coast of the island of Newfoundland.

Whether this launch occurs is very uncertain. For example, a previous report in January 2025 about this launch site suggested that government approvals were still required. It is not known if those approvals have been obtained.

Nordspace is the second company in Canada to propose offering a combined spaceport/rocket service. The other, Maritime Launch Services, first appeared almost a decade ago, but has never gotten off the ground. Nordspace first announced its plans in July 2024, so achieving a first test launch in 2025 will clearly place it ahead of Maritime.

SpaceX gets launch contract from Globalstar

8:58 am

As it appears right now to be the only American rocket company capable of taking on new launch contracts, SpaceX today was awarded a new launch contract from Globalstar to launch its third generation set of satellites.

The press release is not clear about the number of satellites or launches involved, but either way the deal signals SpaceX’s continuing dominance. For larger satellites it has no real competitors. Not only are its launch prices the cheapest, none of its competitors are capable of adding new customers to their launch manifests. In fact, those competitors, ULA, Arianespace, and Blue Origin, are having trouble simply getting their rockets off the ground on a regular basis.

This situation however is likely to change by two years, assuming the new rockets being developed by Rocket Lab, Stoke Space, and Relativity finally begin flying.

Spanish high altitude balloon company to fly tourist flights from South Korea

8:51 am

The Spanish high altitude balloon startup Zero-2-Infinity has now established an office in South Korea with the intention of flying tourist flights from there for a ticket price of about $60k per flight.

Zero 2 Infinity plans to begin its Korean operations with a project called “Byul” — the Korean word for star — which offers a symbolic farewell for pet lovers. The initiative will invite volunteers to send the ashes of their deceased furry companions into the stratosphere, carried in star-shaped, biodegradable capsules. The company aims to begin collecting participants this September, with the first near-space release scheduled for December in Korea.

Byul will apparently be a smaller balloon with no human passengers. The company claims it has already test flown a larger helium balloon with humans aboard to an altitude of 6 miles, and again unmanned to 20 miles. If so it has done so with no publicity at all. This announcement today appears more a push to raise the $70 million the company says it needs to develop this manned balloon capsule.

Returning to Mars’ glacier country

3:21 pm

Overview map

Returning to Mars' glacier country
Click for original image.

Today’s cool image illustrates again why I rail against those who still claim Mars is dry. The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 2, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The picture was labeled simply as a “terrain sample” by the MRO camera team, which almost always signifies that it was taken not as part of any specific science research project or by request by a scientist, but to fill a gap in the camera’s schedule in order to maintain its proper temperature. When such a gap-filler picture is required, the team tries to pick interesting features in that time frame, but don’t always succeed.

In this case, that time frame placed MRO over the northern mid-latitudes and a region I label “glacier country” because practically every picture taken in this region shows glacial features. This picture is no exception. The white dot in the overview map above marks the location, in the Protonilus Mensae area of the 2,000-mile-long strip of glaciers. The arrow in the picture itself shows the downward grade of the glacial flow. The small 2,000-foot-wide crater appears as if the impact occurred on soft ice, and the stippled terrain surrounding it appears to resemble the feature geologists have labeled “brain terrain”, a surface feature unique to Mars and associated with near surface ice, though its exact formation process is not yet understood.

Nor have I cherry-picked this image to prove my point. Its glacial-like features are very typical for this region of Mars. Note for example the inset with the larger crater to the northeast. It appears almost buried by this glacial material, which has poured through the gap in its southwest quadrant to fill it. A close look at all the low lying terrain shows similar glacial-like flows.

Mars is surely not a paradise. It is bone-chillingly cold almost all the time. Its atmosphere is so thin and lacking in oxygen you would quickly suffocate if you tried to breath it. But the data continues to suggest that the red planet has ample supplies of near-surface ice outside of its dry tropics. All future colonists will need to do is dig a bit and process the water out.
