An interesting mesa near Starship's Martian landing zone

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

12:11 pm

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.

COVID health slanderer gets fired for wishing death on Texans because Texas voted for Trump

hall meeting during the COVID panic. Click for video.

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.

This story though has a greater context. » Read more

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

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.

SpaceX launches 28 Starlink satellites

8:40 am

After an unusual pause of launches of several days (likely due to the July 4th weekend), SpaceX last night successfully launched by placing another 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 22nd flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

85 SpaceX
36 China
10 Rocket Lab
8 Russia

SpaceX now leads the rest of the world in successful launches, 85 to 63.
