Looks like the Intuitive Machines IM-1 lander tipped over and ended up in a sideways orientation after landing, similar to the JAXA SLIM lander few weeks ago ☹️
Vertical velocity was a bit high at 6 mph instead of 1, lateral velocity was 2 mph instead of zero. One of the legs is thought to have snagged a rock and caused the lander to tip over.
Solar panels are generating power, the lander is communicating, although the signal is weak.
No pictures yet.

Luckily, they found the problem before the landing sequence and they were able to work out the details of using the NASA LIDAR for landing literally in a few hours.
Need better checklists?

Als Antwort auf AkaSci 🛰️ • • •Dr. Phil Metzger has a simple and clear explanation for why things tend to tip over on the moon -
"When a lander is tipping, inertial forces push it over, while gravity pulls its feet back down flat. On the Moon, gravity is reduced by a factor of 6, but inertial forces are not. *Everything is 6 times tippier on the Moon.*
"
Also, having a low center of gravity and a large base helps gravity win over inertial forces.
These are well-known principles. So why the tall slim designs of late?

You be the judge of the probability of tipping over for these landers.

Als Antwort auf AkaSci 🛰️ • • •Perhaps the width of the IM-1 and other landers is constrained by the design of the Falcon 9 and similar modern rockets, which can carry payloads up to a width of ~4.6m. IM-1's legs are 4.6m wide.
OTOH, Apollo used folding legs, which were 9.5m wide when deployed but only 6m when stowed. Also, the mighty Saturn V rocket could accommodate wider payloads.

Als Antwort auf AkaSci 🛰️ • • •The Intuitive Machines IM-1 Odysseus lander has been spotted and located by NASA’s Lunar Reconnaissance Orbiter (LRO)!
The 1st image below was captured by LRO on Feb. 24, 2024 from an altitude of 90 km.
Lander location = 80.13° S, 1.44° E, 2,579 m elevation.
The 2nd and 3rd images are from the LROC site/database.
The local terrain is sloped at 12°, which can be seen in the 3rd 3D image of the area.

Als Antwort auf AkaSci 🛰️ • • •Update from Intuitive Machines:
The fish-eye image below was posted today. It was taken by Odysseus ~35 seconds after pitching over. The camera is on the starboard aft-side of the lander.
Also - "Based on Earth and Moon positioning, we believe flight controllers will continue to communicate with Odysseus until Tuesday morning."
Do they mean Tuesday, Mar. 5, since the Sun will set at the site on Mar 3 or is it tomorrow because of terrain and orientation?

Als Antwort auf AkaSci 🛰️ • • •Minor update from the Intuitive Machines IM-1 team -
- Odysseus has been sending science data and imagery.
- Battery life is estimated at 10-20 hours, confirming that terrain and solar panel orientation are not favorable.
- They posted another pic taken just before touchdown.
- No mention of EagleCam status
- Few more celebratory words 🙄
Richard Stephenson of DSN Canberra reported data download from the NASA LND1 instrument.

From the image below from a different angle, it appears that IM-1 Odysseus landed on an unfortunate location. Also, quite likely, the low elevation Sun will get blocked by the hills in the West. Also, the orientation of the solar panels will play a role.
