Ispace: Resilience’s failure was due to a hardware issue in laser range finder

In a press conference today, officials of the Japanese startup Ispace explained that the failure of its second lunar lander, Resilience, to land softly on the Moon on June 5, 2025 was due to a hardware issue in its laser range finder that prevented it from providing correct altitude data.

At the same time, they have not yet been able to pin down precisely what caused the failure. It could have been because of unexpected degradation during flight, or possibly a technical fault with the range finder in gathering data at the speeds and altitudes experienced.

The company is forming a task force in partnership with Japan’s space agency JAXA as well as NASA to try to figure out the issue. It is also going to add lidar instrumentation to future missions to provide a backup to the laser range finder. These actions will add about $11 million in additional costs, an amount Ispace says it can absorb.

Ispace is building two more lunar landers, one for NASA in partnership with the American company Draper, and the second for JAXA. It appears both missions are still moving forward.

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

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

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.

NJ Boy scouts win first prize in international rocketry competition

A rocketry team form Boy Scout Troop 74 in New Jersey has garnered first prize in the International Rocketry Challenge held this week at the Paris Air Show in France.

The team competed against top student rocketeers from across the globe. This year, the United Kingdom placed second, followed by France in third, and Japan in fourth.

The “Troop 74 Rocketeers” won the opportunity to represent the United States by securing the title of National Champion at the 23rd annual American Rocketry Challenge National Finals in May. The team bested a record-breaking 1,001 middle and high school teams who participated in the design, build, and launch competition.

This year marked the first time teammates Chase, Makayo (Mak), and Thomas qualified for the National Finals. Their precision in designing, building, and launching a model rocket was unmatched by any other team in the country.

This contest, which has been growing steadily in recent years, suggests a robust next generation of rocket engineers is on the way. And it also appears they will have plenty of job opportunities for their talent.

ULA launches the second set of Kuiper satellites into orbit

ULA this morning successfully placed 27 Kuiper satellites into orbit, its Atlas-5 rocket lifting off from Cape Canaveral in Florida.

This was the second set of Kuiper satellites launched for Amazon. It now has 54 satellites in orbit, with a requirement to launch about 1,600 by July of 2026.

As this was only the second launch in 2025 for ULA, both Atlas-5 launches of Kuiper satellites, the leader board in the 2025 launch race remains unchanged.

77 SpaceX
35 China
8 Rocket Lab
7 Russia

SpaceX still leads the rest of the world in successful launches, 77 to 58.

ULA had predicted it would do 20 launches in 2025. It appears the company will not only not reach that goal, it will not do so by a lot.

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

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.

SpaceX provides update on Starship explosion while fueling for static fire engine test

SpaceX has now posted an update outlining its preliminary conclusions as to the cause of the Starship explosion as the spacecraft was being fueled prior to a static fire engine test on June 18, 2025.

Engineering teams are actively investigating the incident and will follow established procedures to determine root cause. Initial analysis indicates the potential failure of a pressurized tank known as a COPV, or composite overwrapped pressure vessel, containing gaseous nitrogen in Starship’s nosecone area, but the full data review is ongoing. There is no commonality between the COPVs used on Starship and SpaceX’s Falcon rockets.

It remains unclear how long it will take to get that test stand back up and running.

Two lunar orbiters spot the crash site of Ispace’s Resilience lander

Resilience crash site on the Moon, as seen by Chandrayaan-2

Scientists using both NASA’s Lunar Reconnaissance Orbiter (LRO) and India’s Chandrayaan-2 lunar orbiter have spotted the crash site for the private commercial lunar lander Resilience, built and launched by the Japanese startup Ispace.

The picture to the right was taken by Chandrayaan-2. As noted at the LRO website showing its photo:

The dark smudge (60.4445°N, 355.4120°E, -2431.6 m elevation ) formed as the vehicle excavated and redistributed shallow regolith (soil); the faint bright halo resulted from low-angle regolith particles scouring the delicate surface.

The lander attempted a soft landing on June 5, 2025, but because its laser rangefinder was unable to gather good data as to its elevation, it did not decelerate properly and was going too fast when its engines tried for a soft landing. It instead crashed.

France government invests big in Eutelsat-OneWeb

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.

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

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.
