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

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

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.

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.

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

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

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.

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

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

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

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

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.

ESA picks five rocket startups for future launch contracts

European Space Agency

Capitalism in space: The European Space Agency (ESA) today announced that it has chosen five rocket startups — out of twelve that applied to its “European Launcher Challenge” — now approved to bid on future ESA launch contracts.

The startups are Isar Aerospace and Rocket Factory Augsburg from Germany, PLD Space from Spain, MaiaSpace from France, and Orbex from Great Britain. Though none have successfully completed a first launch. all five showed the most advancement. Isar has had one attempted launch failure, while Rocket Factory lost its rocket during a static fire test just before launch. PLD meanwhile has achieved a short suborbital test, while Orbex has said it was ready to launch three years ago but was blocked by red tape in the United Kingdom.

MaiaSpace is technically the least advanced, but it is also a subdivision wholly owned by ArianeGroup, a partnership of Europe’s largest aerospace companies, Airbus and Safran. It was also established in partnership with France’s space agency CNES. Thus, it has well-established connections within Europe’s aerospace industry that makes it favored.

The goal of this ESA program is to shift from the government model it has used for decades, where ESA builds and owns the rockets, to develop a competitive rocket industry of independent companies that market their rockets to ESA for contracts. ESA has seen the success in the U.S. when NASA shifted to this capitalism model in the past decade, and wishes to emulate this.

Whether it remains uncertain. ESA is still mired by bureaucratic government thinking, as illustrated by the next phrase in this challenge:

The next phase of the proposal will see ESA open dialogue between the preselected companies and their respective Member States. This process will help formalise the proposal ahead of the agency’s Ministerial-Level Council meeting (CM25), which will take place toward the end of the year. At CM25, Member States are expected to formally commit funding to the initiative. Following the meeting, ESA will issue a Phase 2 call for proposals, which will be restricted to the preselected candidate companies. European Launcher Challenge contracts will then be awarded after a final evaluation period.

The ESA’s very nature seems to impose odious bureaucratic rules on its member nations that could hinder these private companies. For example, these rules now block any other independent rocket startups from bidding on contracts. Like the bootleggers during Prohibitioin, the ESA has essentially divided competition up by territory and given it to these favored companies. No one else is allowed in.

Two Russian satellites are maneuvering toward an American military satellite

Two Russian “inspector” satellites, launched together in 2022 but now separated, appear to be maneuvering toward an American military satellite and are about to position themselves to within 30 and 50 miles respectively every four days.

[O]n June 26, 2025, a new object was apparently ejected from the main satellite at a separation speed of just around 10 kilometers per hour, according to an estimate by Jonathan McDowell.

By the end of June 2025, Object C (Full ID — 2022-089C), as the newly released satellite was identified in the US Space Force catalogue, was around 140 kilometers from its Kosmos-2558 “mother vehicle,” according to observations by Marco Langbroek. It was tracked in a 545 by 451-kilometer orbit, with an inclination 97.24 degrees toward the Equator. On July 3, 2025, at around 18:42 UTC, Object C made a sudden orbit-lowering maneuver descending to an altitude of around 435 kilometers, while Kosmos-2558 remained in its original orbit.

According to Nico Janssen, the newly formed orbit would put Object C within 81 kilometers from USA-326, on July 5, 2025, at around 00:54:20 UTC. In the meantime, Kosmos-2558 would pass at a minimum distance of nearly 49 kilometers from USA-326 on the same day, at around 09:40:50, Janssen predicted on the Seesat-L Internet message board on July 4, 2025.

Russia’s anti-satellite technology is based on tests several decades ago whereby it brought a killer satellite close to a target satellite and destroyed both by blowing up the killer satellite. These maneuvers now are not likely aimed at such a test, destroying the American classified military satellite. Instead, Russia likely wants to obtain close-up photography and data collection about it. The maneuvers however do prove once again that Russia’s anti-satellite technology is viable.

A Martian meteorite discovered in Africa is up for auction

A Martian rock that fell as a meteorite in Africa and was discovered by a professional meteorite hunter and is the largest such Mars rock found so far is about to go up for sale by auction.

NWA16788 is the largest known piece of Mars on Earth, and its internal composition suggests it was disgorged from the surface of the Red Planet by an asteroid impact so extreme that it turned some of the meteorite’s minerals into glass.

Looking certain to blow past its lower estimate of US$2.0 million, this monumental 54-lb (24.67-kg) lump of Mars has already been bid to $1,920,000 (inc Buyer’s Premium) 12 days before the on-line hammer falls, and even its $4-milllion upper estimate doesn’t look safe with this much interest so early in an online auction.

The expected high price is partly because of the meteorite’s size, and partly because almost such meteorites are found by scientists working for NASA, and are thus never made available for sale. To have one available for purchase is rare indeed.
