Parker completes its 24th close fly-by of the Sun

10:13 am

The Parker Solar Probe has successfully completed its 24th close fly-by of the Sun, the last of its initial primary mission, matching the distance and speed record set during two previous fly-bys.

Parker Solar Probe checked in with mission operators at the Johns Hopkins Applied Physics Laboratory (APL) in Maryland — where it was also designed and built — on Sunday, June 22, reporting that all systems are healthy and operating normally. The spacecraft was out of contact with Earth and operating autonomously during the close approach.

During this flyby, the spacecraft also equaled its record-setting speed of 430,000 miles per hour (687,000 km per hour) — a mark that, like the distance, was set and subsequently matched during close approaches on Dec. 24, 2024, and March 22, 2025.

The data obtained during this fly-by will be beamed back to Earth in the coming months, as Parker moves to the outer part of its orbit, farther from the Sun.

Though this completes the planned orbits of the mission’s primary mission, the proposed Trump budget continues to fund the spacecraft’s operation for the next five years, allowing it to monitor changes in the Sun as it ramps down from solar maximum to solar minimum.

France’s space agency awards ArianeGroup contract to build methane-fueled engine

10:12 am

France’s space agency CNES this week awarded ArianeGroup, the rocket partnership between Airbus and Safran that builds the Ariane-6 rocket a contract to develop a more powerful methane-fueled rocket engine.

Aiming to reach between 200 and 300 tons of thrust, the new engine will be twice as powerful as the current Vulcain 2.1 main stage engine that propels Ariane 6.

No details about cost or time schedule were released.

The significance of this deal isn’t the engine, but that it was issued directly to ArianeGroup by France’s space agency, instead of through the European Space Agency’s (ESA) Arianespace commercial arm, as has been routine for the past three decades. The deal illustrates how the ESA is essentially beginning to break up. Rather than go through it, its individual nations are now going it alone, each providing support and funding to their own commercial private space startups. Germany began this process, encouraging the development of three new rocket companies (Rocket Factory Augsburg, Isar, and Hyimpulse). Spain and Italy soon followed with their own new rocket companies, (PLD and Avio respectively). France, which until recently lobbied to keep the old government model alive in ESA, has in the past year shifted strongly to the capitalism model.

This contract only underscores this shift.

Isaacman hints of future space plans

9:11 am

In receiving an award from a space advocacy group on June 21, 2025, billionaire Jared Isaacman hinted that his future space-related plans could include working with science organizations to finance scientific probes.

[Had he become NASA administrator he had wanted] NASA to partner with academic organizations on missions where such organizations would have had a bigger role in funding. “My priorities would have been leadership in space and the orbital economy,” he said, “and trying to introduce a concept where NASA could help enable others to conduct interesting scientific missions, getting academic organizations to contribute.”

That was something he said he might be interested in pursuing outside the agency. “I wouldn’t mind maybe trying to put that to a test and see if you could fund an interesting robotic mission, just to show that it can be done, and try and get some of the top tier academic institutions who want to perform. So that’s on my mind.”

He also indicated that he generally has no problem with the Trump administration’s proposed NASA cuts, noting that such academic organizations need to figure out how to work with less money.

Despite this statement, it appears he is still unsure of what he will do next in space. He has not restarted his Polaris Dawn manned program — suspended when he was nominated to become NASA administrator — and has said that right now he is more focused taking advantage of this unexpected break from work to spend more time with his family.

ESA partners with French company to build space plane “demonstrator”

1:12 pm

The European Space Agency (ESA) and the French company Dassault Aviation yesterday announced a partnership for building a space plane “demonstrator” that will lay the groundwork for developing a family of such spacecraft dubbed Vortex.

The ESA press release is here. Both this release and the Dassault release linked to above provided little detailed information, other than the demonstrator will be a small scale suborbital testbed for eventually developing the full scale orbital vehicle. Neither a budget nor time schedule were even hinted at.

ESA has funded a number of these demonstrators in the past decade — Themis and Callisto come to mind — all of which are behind schedule and have as yet not flown. It will be interesting to see if this project fares better, as it seems it is being led by a single commercial company rather than the government run mishmashes of the other projects.

France government invests big in Eutelsat-OneWeb

10:59 am

According to the satellite company Eutelsat-OneWeb, the French government has now committed more than a billion dollars in investment capital to the company, doubling its stake to almost 30%.

France would more than double its stake in Eutelsat to nearly 30% as part of a $1.56 billion capital raise backed by multiple shareholders, bolstering the French operator’s plans to refresh its OneWeb constellation amid Starlink’s growing dominance.

The funds would be raised in two parts before the end of the year, Eutelsat announced June 19, a day after the French military agreed to buy OneWeb services over 10 years in a deal potentially worth up to one billion euros ($1.15 billion).

OneWeb itself almost went bankrupt until it was saved by cash from a major Indian investor and the government of the United Kingdom. This new deal means that the merged company is largely controlled by France, the UK, and India.

Chinese pseudo-company Landspace completes static fire test of 1st stage of its Zhuque-3 reusable rocket

10:12 am

The Chinese pseudo-company Landspace today successfully completed a static fire test of 1st stage of its Zhuque-3 reusable rocket, firing all nine engines for 45 seconds.

This lays the groundwork for the first launch attempt of this rocket.

The first Zhuque-3 orbital launch attempt was earlier slated for the third quarter of the year and would carry a prototype of the reusable Haolong cargo spacecraft, designed by the Chengdu Aircraft Design Institute under the Aviation Industry Corporation (AVIC). The test is part of a program for low-cost cargo delivery to the Tiangong space station. Landspace did not provide a timeframe for the launch in its static fire test statement.

It appears increasingly that three different Chinese pseudo-companies are getting close to launching reusable rockets within the next year or so. In addition to Landspace, there is CAS-Space (the rocket division of a government agency) and Space Pioneer. In addition, there five other pseudo-companies doing similar rocket hop tests. All are working under the supervision of the government, which requires them to share data.

India transfers ownership of SSLV rocket from space agency to government-owned private aerospace company

9:55 am

Capitalism in space: As part of the Modi government’s effort to switch its space industry from something owned and run entirely by its space agency ISRO, it has now awarded the ownership and control of ISRO’s newest and smallest rocket, the SSLV, to the aerospace company Hindustan Aeronautics Limited (HAL).

The company paid about $60 million for the purchase, and the right to build, market and launch it. It hopes to build between 6 to 10 rockets per year, depending on launch demand.

This transfer is not as radical as it appears. Though HAL operates mostly as an independent aerospace company, it is still owned by the government with its board of directors appointed by the president of India. The rocket will thus still be owned and controlled by the government, not a private company.

At the same time, this deal acts to shift power away from the space agency ISRO, which I suspect is the plan: Divvy up ISRO’s assets, which will eventually make it harder for it to block independent operations by private companies. As part of that program, the government has also transferred construction of the larger PSLV rocket from ISRO to a consortium of companies.

Whether this shift can create an independent and competitive rocket industry in India is very unclear. In many ways the country’s strategy so far mimics more China’s pseudo-company approach (where the companies raise investment capital, compete for government and commercial contracts, but are always under the full control and supervision of the government) then it does America’s free enterprise system (where ownership and control resides entirely with the companies, and the government only buys the services it needs from them).

The American model is by far the most successful in encouraging innovation and competition for the least cost. The Chinese model produces some results for less cost, but relatively little innovation. Instead, it copies what Americans do.

NASA delays Axiom manned mission again

9:11 am

Without providing any specific details, NASA today announced that it has once again scrubbed the June 22, 2025 launch of Axiom’s Ax-4 manned mission to ISS as it assesses the Russian repairs to the air leaks in the Russian Zvezda module.

The space agency needs additional time to continue evaluating International Space Station operations after recent repair work in the aft (back) most segment of the orbital laboratory’s Zvezda service module. Because of the space station’s interconnected and interdependent systems, NASA wants to ensure the station is ready for additional crew members, and the agency is taking the time necessary to review data.

No new launch date has been set. Because the agency provides so little specific information, we don’t know if the air leak repairs are working, are failing, or have indicated even more serious problems that make any station docking a greater risk. Almost certainly, this latter fear is unfounded and the repairs have succeeded in stopping or slowing the loss of air, but the paucity of information from NASA allows for wild speculations. It would be better if the agency told us what it has so far learned, and exactly why that knowledge requires it to extend the data-gathering time period.

Ground-based imagery now suggests China has completed a docking and undocking of two robotic servicing satellites

10:28 am

According to ground-based imagery by the commercial company S2A, China’s Shijian-21 and Shijian-25 robotic servicing satellites appear to have completed a docking and undocking on June 13 and June 14, 2025.

China’s Shijian-21 and Shijian-25 satellites had been moving toward each other in geosynchronous orbit, around 22,236 miles (35,786 kilometers) above the equator, Spacenews reported on June 6. And now the pair appear to have had a brief first encounter, according to observations from the ground.

Optical tracking by the space situational awareness firm s2a systems shows a close approach between the two on June 14, with the pair, at times, virtually unresolvable from the other. This suggests that Shijian-21 and Shijian-25 made at least a test-run close approach and may have even performed a docking and undocking test.

You can see video of the first apparent docking here.

Shijian-21 was launched in 2021, and was used to grab a defunct Chinese geosynchronous satellite and tug it to a graveyard orbit. Shijian-25 was launched in January 2025 to test robotic servicing of satellites. These maneuvers with Shijian-21 appear to be part of those tests.

Monaco-based startup unveils its proposed European-built lunar rover

10:17 am

Capitalism in space: The Monaco-based startup Venturi Space, this week unveiled its own proposed European-built lunar rover, dubbed Mona Luna. and offered it to both the European Space Agency (ESA) and France’s CNES space agency.

Venturi has received some support from ESA for key technologies needed for the rover. The company is hoping to win support for a rover development project at ESA’s ministerial conference in late November, when member states will decide on funding for agency programs for the next three years. Antonio Delfino, Venturi’s director of space affairs] argued a rover like Mona Luna fit a gap in Europe’s exploration plans. Mona Lisa is designed to be delivered to the lunar surface on ESA’s Argonaut lander, which would launch on an Ariane 64.

The company has said it is willing to commit some of its own investment capital to develop the rover, should either ESA or CNES decide to buy it. Whether ESA or CNES agree to build this rover however will likely depend on whether either has a program to land on the Moon. At the moment the status of NASA’s Artemis program is unclear, and it was that program that Europe was relying on to get to the Moon.

Russia launches classified military satellite using its Angara-5 rocket

9:50 am

Russia today successfully launched a classified military satellite, its Angara-5 rocket rocket lifting off from its Plesetsk spaceport in northeastern Russia.

This was the fifth flight of the Angara-5 rocket, the most powerful version in the Angara family of rockets that Russia first proposed three decades ago to replace its older rockets and has had an extremely slow development history. Its core stage and four strap-on boosters crashed in drop-zones across Russia,

On June 9, 2025, the administration of the Kolpashevo District in the Tomsk Region of Russia declared several communities at risk of debris impact during an Angara-5 launch scheduled around 06:00 Moscow Time on June 19, 2025. The danger area covered the Verkneketsky, Kolpashevsky, Kargasoksky and Parabelsky Districts and was located around 65 kilometers north-west of Lake Tresh. This particular area, located around 2,320 kilometers downrange from Plesetsk, would normally be used as a drop zone for the second stage of an Angara rocket heading to an orbit with an inclination 63.4 degrees toward the Equator.

The rocket’s first stage boosters were expected to fall in the Komi Republic around 850 kilometers downrange, while the third stage would splash down in the Pacific Ocean, east of the Philippines, where the Russian authorities also declared a danger zone.

The leaders in the 2025 launch race:

76 SpaceX
34 China
8 Rocket Lab
7 Russia

SpaceX still leads the rest of the world in successful launches, 76 to 56.
