NASA on Starliner: Too much freedom caused the failure!

2:59 pm

Starliner docked to ISS
Starliner docked to ISS in 2024.

NASA today released its final investigation report on the causes behind the Starliner thruster issues during that capsule’s only manned mission in ISS, issues that almost prevented the spacecraft from docking successfully and could have left it manned and out-of-control while still in orbit.

You can read the report here [pdf]. NASA administrator Jared Isaacman made it clear in his own statement that the Starliner incident was far more serious than originally let on.

“To undertake missions that change the world, we must be transparent about both our successes and our shortcomings. We have to own our mistakes and ensure they never happen again. Beyond technical issues, it is clear that NASA permitted overarching programmatic objectives of having two providers capable of transporting astronauts to-and-from orbit, influence engineering and operational decisions, especially during and immediately after the mission. We are correcting those mistakes. Today, we are formally declaring a Type A mishap and ensuring leadership accountability so situations like this never reoccur. We look forward to working with Boeing as both organizations implement corrective actions and return Starliner to flight only when ready.”

A Type A mishap is one in which a spacecraft could become entirely uncontrollable, leading to its loss and the death of all on board. Though Starliner was NOT lost, for a short while as it hung close to ISS that result was definitely possible. Its thrusters were not working. It couldn’t maneuver to dock, nor could it maneuver to do a proper and safe de-orbit. Fortunately, engineers were able to figure out a way to get the thursters operational again so a docking could occur, but until then, it was certainly a Type A situation.

The report outlines in great detail the background behind Starliner’s thruster issues, the management confusion between NASA and Boeing, and the overall confused management at Boeing itself, including its generally lax testing standards.

The report’s recommends that NASA impose greater control over future commercial contracts, noting that under the capitalism model that NASA has been following:

Pluto’s splotched surface

Pluto's splotched surface
For original images go here and here.

Cool image time! The panorama above was created using two photographs (found here and here) taken by New Horizons during its close fly-by of Pluto on July 14, 2015. It looks at Pluto’s western limb, well lit by the Sun, from a distance of approximately 60,000 miles.

I pulled these images from the New Horizons’ archive specifically because I don’t remember ever seeing them publicly released by the science team. More important, they show a surface far more alien than other more well-known New Horizon pictures. Are those round splotches impact craters or some alien type of volcanic caldera? Note also the vertical cracks that appear to divide this terrain near the center.

It would be a serious mistake to make any conclusions. In the emptiness of the outer solar system, the impact rates are going to be far less than in the inner solar system, so assuming impacts is dangerous. Pluto meanwhile has an alien surface of frozen nitrogen seas often filled with floating mountains of frozen water ice. For it to also produce weird volcanic eruptions of nitrogen, sublimating away like bubbling tomato sauce when it is simmering, is quite possible.

Chinese pseudo-company Landspace targeting April-June for 2nd Zhuque-3 launch

10:24 am

The Chinese pseudo-company Landspace now hopes to make its second orbital launch and recovery attempt of its Zhuque-3 rocket sometime in the April-June ’26 time frame.

The first launch in December ’25 was a success, getting its upper stage into its planned orbit. The attempt to vertically land the first stage however failed. The stage came down almost precisely on its target landing pad, but the engines failed and so it crashed instead of landing softly.

Officials say that they also hope to begin reusing the first stage quickly, if it should land successfully, with the first reuse planned for late this year. The rocket itself has about two-thirds the capacity of SpaceX’s Falcon 9, and is being marketed to launch the half-dozen giant satellite constellations China is presently attempting to place in orbit.

Since the beginning of this year there has been a decided pause of news from China’s pseudo-companies. I have speculated this dearth of the normal stream of PR announcements might be related to a power-play by the new government agency created last year to supervise these pseudo-companies. It also could simply be the government has told them to tone it down a bit. Better to sell actual achievement than empty plans.

The dimmest galaxy yet found

9:57 am

The dimmest galaxy yet found
Click for original image.

The uncertainty of science: Using ground-based and orbiting telescopes, astronomers think they have identified what might be the dimmest galaxy yet discovered, revealed almost entirely not from its stars but from the four globular clusters that reside within or near it.

The image to the right, cropped and sharpened to post here, shows that galaxy, dubbed CDG-2, along with those four globular clusters. From the press release:

To confirm one of the dark galaxy candidates, astronomers employed a trio of observatories: the NASA/ESA Hubble Space Telescope, ESA’s Euclid space observatory, and the ground-based NAOJ Subaru Telescope in Hawaii. Hubble’s high-resolution imaging revealed a close collection of four globular clusters in the Perseus galaxy cluster, 300 million light-years away. Follow-up studies using Hubble, Euclid, and Subaru data then revealed a faint, diffuse glow surrounding the star clusters – strong evidence of an underlying galaxy.

“This is the first galaxy detected solely through its globular cluster population,” said David. “Under conservative assumptions, the four clusters represent the entire globular cluster population of CDG-2.”

Preliminary analysis suggests CDG-2 has the luminosity of roughly 1 million Sun-like stars, with the globular clusters accounting for 16% of its visible content.

The scientists next claim that 99% of the galaxy’s mass is made up of dark matter, a material no one has yet detected except for the gravitational influence its invisible mass imposes on visible objects. It appears the astronomers don’t believe the mass that has been detected is sufficient to hold this galaxy together, and thus they need dark matter to explain its existence.

I simply wonder if the distances involved simply make the matter hard to see.

No matter. This is a cool discovery, because it tells us there is much out there hidden in the darkness we will always find difficult if not impossible to detect.

Engine problems for Japan’s lunar lander company Ispace

9:27 am

According to company officials, the Japanese lunar lander company Ispace is having issues with the engine is has been developing for its next (and third) lander mission — a joint project with the American company Draper — problems that have now delayed the mission from ’26 to ’27.

In an earnings call discussing its fiscal third-quarter financial results this month, ispace executives said issues with development of the new VoidRunner engine could delay the company’s next lander mission. VoidRunner is a joint project between ispace’s U.S. subsidiary and Agile Space Industries, a U.S. space propulsion company, announced in May 2025. It replaced an Agile Space engine originally planned for use on the Apex 1.0 lander that ispace U.S. is developing.

Changing the engine required modifications to the lander design, Ispace said at the time, delaying its use on a mission led by Draper for NASA’s Commercial Lunar Payload Services, or CLPS, program from 2026 to 2027. That mission to the lunar farside is designated Mission 3 by Ispace.

Ispace has made two attempts to land on the Moon. In both cases, the mission worked perfectly until the last moments, resulting in a crash rather than a soft landing. In the first case software had the engines shut down when the spacecraft was still about three miles above the ground, while in the second case the spacecraft’s laser range-finder provided incorrect altitude data.

It presently has contracts for three more missions, the one for NASA working with Draper, a second for Japan in ’28, and a third for Europe in ’29. That it has had to replace the engines on the first (and might have to do it on the second) is a very bad sign. Usually it is best practice to build and test the engine first, get it right, and then build the spacecraft or rocket around it. Replacing an engine usually signals larger design problems that are difficult if not impossible to fix.

Sorry about the lack of posts…

2:24 pm

I feel obliged to apologize for the general low rate of posting the past few days. First I am still fighting this head cold, which though it appears to be fading it still leaves me foggy-brained at times. This situation was made worse today when the profile vanished from my Thunderbird email program. How it vanished remains a mystery, but it took me more than an hour to upload a back-up (from a week ago) and get it to work with the program. Thus I lost about a week’s emails.

Hardly a tragedy but all this has been quite exhausting. Hopefully by tomorrow things will run better.

Regardless, I want to thank my readers for their kind words and support. It is truly appreciated.

The United Arab Emirates (UAE) yesterday announced it is extending the mission of its Al-Amal Mars orbiter (“Hope” in English) to 2028, significantly beyond its initial planned mission of two years.

Launched in July 2020, the Hope Probe successfully entered Mars orbit in February 2021 after a seven-month interplanetary journey, marking a historic achievement as the first Arab nation to reach the Red Planet. Originally designed as a two-year mission to observe and study Mars’ atmosphere, the probe has far exceeded expectations. Since reaching Mars, it has gathered around 10 terabytes of scientific data, shared through more than a dozen datasets with research institutions worldwide.

The probe itself was mostly built by American engineers and organizations, as part of a deal to train UAE students. Once in operation around Mars, the UAE and those students took over almost all operations. It orbits Mars in a very wide orbit, allowing it to study global weather and atmosphere conditions, such as dust storms.

Bahamas allows SpaceX to resume Falcon 9 landings inside Bahamian waters

8:49 am

The Civil Aviation Authority of the Bahamas (CAAB) this week announced that it is allowing SpaceX to resume Falcon 9 landings inside Bahamian waters.

In a statement, CAAB said that one landing is scheduled for Wednesday night between 5:00 pm and 9:30 pm (local time). “All requisite regulatory and environmental reviews and clearances have been completed in accordance with established aerospace safety and operations protocols,” CAAB said, reminding the population that, depending on weather and atmospheric conditions, “one or more sound booms may be heard during the landing sequence”.

SpaceX had completed one landing in February 2025, but the CAAB then paused further landings two months later, claiming it wanted to do a full environmental review.

There was also the issue of a SpaceX $1 million donation to the University of the Bahamas. Maybe the CAAB wanted to wait until the check cleared.

As should be expected, a fringe of anti-Musk activists began screaming “environmental disaster” and getting the full support of the propaganda press. The claim is utterly stupid, considering SpaceX has landed hundreds of Falcon 9s in the past decade harmlessly.
