SpaceX’s eighth orbital test flight of Starship/Superheavy ends like the seventh flight
Starship just before loss of signal
Today’s eighth orbital test flight of SpaceX’s Starship/Superheavy giant rocket has turned out to be almost identical to the seventh flight, with Superheavy completing its mission with a perfect chopstick catch at the launch tower in Boca Chica and Starship failing just before engine shutdown that would have put it into its orbit.
The screen capture to the right shows that moment. Note that graphic on the far lower right. It indicates that only two of the outside engines are firing, in an asymmetrical configuration. As a result Starship began tumbling, as shown by the fact that the Earth is not visible in the background. Shortly thereafter contact was lost, and I expect the flight termination system took over to destroy the ship. Expect videos from the Caribbean of it burning up overhead in the next day or so.
Superheavy however completed the third ever capture by the launch tower chopsticks. Musk has indicated that the company is pushing to reuse a Superheavy booster as soon as possible. The lose of Starship and the fact that two Superheavy engines shut down prematurely during the boost-back burn after stage separation likely delays that reuse at least one or two test flights. First, this Superheavy had issues, that might be solvable but they nonetheless exist.
More important, the loss of Starship just before its orbital coast once again means SpaceX was unable to do any of its orbital and return test program. It will not make sense to risk the next Starship flight with a used Superheavy when testing Starship has now been delayed twice.
Nor does it matter much. It will take many more launches before this rocket is reliably reusable. The first priority now is to make it more reliable on its first launches. Expect SpaceX to target the next test flight for sometime in mid- to-late April.

- Astroforge releases a detailed debrief of its Odin mission failure once in space
It seems their engineers have gained a great deal of experience that can be applied to future missions, whether with Astroforge or elsewhere.
- The shipping container transporting the next Cygnus freighter to its launch site has been damaged
It is presently unknown whether the capsule was unharmed. NASA is putting more ISS cargo on the next SpaceX Dragon, just in case.
Athena sits at an unknown angle on the Moon, hampering operations
Yellow cross indicates Athena’s targeted landing site
According to the CEO of Intuitive Machines, Athena is sitting an an unknown angle on the Moon, impacting the possibility of all surface science operations.
The tilt is hampering their ability to use the high gain antenna which they need use to download most of their data. They do not know the angle, or the cause of this issue. It could simply be that the ground slope is too severe. It is also possible the spacecraft, which has a relatively high center of gravity, fell over on its side because of that slope. Moreover, they do not know at the moment exactly where the spacecraft landed, though they know it landed on Mons Mouton as planned. They need to download pictures from the spacecraft, as well as from Lunar Reconnaissance Orbiter (LRO) in orbit to determine precisely the location and the situation.
It is also unclear what payloads will be impacted by this situation. It could be that most if all could be utilized, but that question cannot be answered until they learn more. I suspect both the mini-rover and the Grace hopper will be affected the most, as the tilt might make it impossible to deploy either.
For Intuitive Machines this situation is very unfortunate. It has sent two unmanned lunar landers, and both have had issues at landing, though it must be emphasized that the issue on today’s second landing might have nothing to do with the company’s engineering at all.
Is a supermassive black hole is hidden in the Large Magellanic Cloud?
Based on the motions of a number of runaway stars on the edge of the Milky Way that are moving so fast they will leave the galaxy, astronomers believe that many were accelerated not by the galaxy’s own central supermassive black hole but a previously undetected supermassive black hole at the center of the Large Magellanic Cloud, one of the Milky Ways nearby dwarf galaxies.
To make this discovery, researchers traced the paths with ultra-fine precision of 21 stars on the outskirts of the Milky Way. These stars are traveling so fast that they will escape the gravitational clutches of the Milky Way or any nearby galaxy. Astronomers refer to these as “hypervelocity” stars.
Similar to how forensic experts recreate the origin of a bullet based on its trajectory, researchers determined where these hypervelocity stars come from. They found that about half are linked to the supermassive black hole at the center of the Milky Way. However, the other half originated from somewhere else: a previously-unknown giant black hole in the Large Magellanic Cloud (LMC).
You can read the paper here [pdf]. This result was made possible by the very precise location and velocity data of over a billion stars measured by Europe’s Gaia satellite.
Based on the available data, the scientists estimate (with great uncertainty) the mass of this supermassive black hole, which the scientists have dubbed LMC* (pronounced “LMC star”), to be about 600,000 times the mass of the Sun, quite big but significantly less than the mass of the Milky Way’s central black hole, Sagittarius A* (pronounced “A-star”), which is estimated to be about 4.3 million times the mass of the Sun.
The mystery to solve now is why this super massive black hole is so quiet. It has literally emitted no obvious energy in any wavelength in the past seven decades, since ground- and space-based telescopes went into operation capable of detecting such emissions. Even the relatively inactive supermassive black hole at the Milky Way’s center, Sagittarius A* (pronounced “A-star”) emits distinct radio energy that the first radio telescopes were able to detect almost immediately.
Intuitive Machines’ Athena lander touches down softly; engineers are assessing spacecraft condition
Though Intuitive Machines’ Athena lander has apparently softly landed near the south pole of the Moon, there remains uncertainty about the spacecraft’s status. Engineers have contact with Athena, and are apparently shutting down the landing equipment in order to make Athena safe for surface operations.
Unlike the previous landing, the spacecraft is upright and responding fully as expected. It appears the main issue is the position of Athena relative to the horizon. This is important as it determines the best antenna’s to use to upload and download data to and from Earth.
A full update will be provided at a press conference scheduled for 4 pm (Eastern) today. I have embedded the live stream of that conference below.

Scientists discover the oldest known crater on Earth
Though erosion has made it visibly unnoticeable now, scientists have discovered geological features 3.5 billion years old in northwestern Australia that suggest the location is the oldest impact crater known on Earth.
The crater was discovered by geologists at Curtin University and the Geological Survey of Western Australia in the Pilbara region of northwestern Australia. While it’s hard to see directly as a classic crater shape, due to its age, the team found it through other evidence – namely “shatter cones,” geological features that form only when exposed to extreme pressures, like meteorite impacts or underground nuclear explosions.
The newly discovered crater is estimated to be at least 100 km (62 miles) wide, which suggests the original object that crashed into Earth was traveling at more than 36,000 km/h (22,000 mph), and would have caused destruction on a global scale. The impact appears to have occurred 3.47 billion years ago. “Before our discovery, the oldest impact crater was 2.2 billion years old, so this is by far the oldest known crater ever found on Earth,” said Professor Tim Johnson, co-lead author of the study.
You can read the published paper here. There are many assumptions and uncertainty in this conclusion, but it is likely correct.
The impact likely occurred during a time period scientists call the Late Heavy Bombardment, when the planets in the solar system were beginning to accrete out of the thick disk of dust and rocks that surrounded the Sun. On Earth most of the evidence of this bombardment is gone, destroyed by erosion and plate technoics. We only know about it from the craters on the Moon, Mercury, and Mars, where erosion has left those impacts mostly untouched.
Ariane-6 successfully launches for the second time
The European Space Agency’s (ESA) commercial arm, Arianespace, today successfully launched from French Guiana its new Ariane-6 rocket for the second time, this time placing its first commercial payload, a military Earth imaging satellite, into orbit.
As of posting the satellite has not yet been deployed by the upper stage, as several additional engine burns are required over then hour or so to place it in the right orbit. As there were some issues with this upper stage on the rocket’s first launch, the successful completion of these burns is critical for the rocket’s future. So far the first major burn has been completed as planned. UPDATE: The payload has been successfully deployed in the proper orbit.
This was Europe’s first launch in 2025, so there is no change in leader board for the 2025 launch race:
26 SpaceX
9 China
3 Russia

India’s space agency ISRO begins construction of second spaceport
India’s spaceports
After several years getting the real estate as well as the necessary regulatory approvals, India’s space agency, Indian Space Research Organization (ISRO), has now begun construction of it second spaceport, dubbed Kulasekaranpattinam, near the southern tip of India.
The map to the right shows the location. The Sriharikota spaceport has been used by the agency for decades. The Agnikul site was used once by one of India’s rocket startups for a suborbital launch, but it is unclear if it will be upgraded to a full launch site in the future.
Kulasekarapattinam was one of the areas recommended for the launchpad even before the rocket launchpad was set up in Sriharikota due to its strategic geographical location near the equator. It is located on the east coast and there is no land to the south of it, allowing for direct southward launches over the Indian Ocean. This will minimize fuel consumption and maximize payload capacity for small satellite launch vehicles (SSLVs), particularly beneficial for cost-effective commercial satellite launches.
The site also avoids the need for complex “dogleg” manoeuvres around Sri Lanka. The manoeuvre involves a sharp turn or bend in a launch trajectory to avoid collisions or falling debris into populated areas, which would require additional fuel.
As part of the breaking ground ceremonies, ISRO scientists also completed a small suborbital rocket launch from this new site, reaching an altitude of 46 miles before falling back into the Indian Ocean.
Future now very dim for Lunar Trailblazer
Though engineers are continuing attempts to re-establish contact with the orbiter Lunar Trailblazer as it flies outward after launch, the situation is becoming increasingly grim.
Based on telemetry before the loss of signal last week and ground-based radar data collected March 2, the team believes the spacecraft is spinning slowly in a low-power state. They will continue to monitor for signals should the spacecraft orientation change to where the solar panels receive more sunlight, increasing their output to support higher-power operations and communication.
The problem is that, without communications, the spacecraft was not able to do several mid-course corrections that would have sent it on the right path to the Moon. Though it might still be possible to get it to the Moon, communications must be re-established soon to do so.
Europa Clipper completes Mars fly-by
Data from Europa Clipper has now confirmed that its March 1, 2025 Mars fly-by was successful, putting it on the right trajectory to do a fly-by of Earth in December 2026.
When Europa Clipper launched, navigators deliberately aimed a little away from Mars to avoid any possibility of a launch error turning into a Mars impact. Since then, they’ve performed three deep-space trajectory correction maneuvers to line up for the encounter. Europa Clipper whizzed by Mars at 17:57 UT, only 2 km away from the target height of 884 km. A final maneuver, planned for March 17th, will correct any residual trajectory error.
Only two instruments were activated, mostly as tests to see if they were operating properly. Though the data has not yet been downloaded back to Earth, engineers say that it appears all worked as expected.
If the Earth fly-by in 2026 is successful, Europa Clipper will rendezvous with Jupiter in April 2030, entering an orbit that will fly past Europa numerous times.
Blue Ghost lunar surface operations proceeding as planned
According to a Firefly update today, all of Blue Ghost’s planned lunar surface operations are working as planned.
Eight out of 10 NASA payloads, including LPV, EDS, NGLR, RAC, RadPC, LuGRE, LISTER, and SCALPSS, have already met their mission objectives with more to come. Lunar PlanetVac for example successfully collected, transferred, and sorted lunar soil from the Moon using pressurized nitrogen gas.
I have embedded below the video posted at the link of Lunar PlanetVac deploying and then blowing that gas to capture surface soil.
