I also don't understand why the Intuitive Machines lander is so tall? They kind of set themselves up for this to happen, that and the fact that it was moving sideways as it was landing, as opposed to straight down. Well, that's what the animation showed during the landing anyways.

It was moving sideways because the horizontal velocity vector was probably not nulled out to zero feet per seconds

Any lander with a high CG (Odie, Starship) is more of a concern; you absolutely have to kill all the horizontal speed for those puppies else problems are likely. Indeed, "short and squat" results in a smaller "Pucker factor."

As far as not mentioning the fact that it is on its side, that's typical government spin. IMO, ending up in the right orientation is necessary for a landing to be successful. They got 2 out of 3 - soft touchdown and signal/some data from the vehicle.

It seem the Intuitive Designs mission has reached its tipping point.

I know that neither NASA or IM has made ANY kind of an update to their websites about it since the day of the press conference. Nothing. But I did read where Intuitive Machines stock price dropped 30% after the CEO mentioned in that press conference that the lander was on its side.

There's an update on the IM website this morning. They summarized the best features of their flight, and don't mention that the lander is on its side. IM achieved a landing that is "the furthest south any vehicle has been able to land on the Moon and establish communication with ground controllers."

The best photo they could do is 30 meters above the surface of the moon and then one from the surface while it's on its side... and now it's powered down.

Eric Berger over at Ars Technica posted an article yesterday about the lander and the obstacles they had to overcome. One part piqued my interest:
The company has an incredible photo of this moment showing the lander upright, with the snapped leg and the engine still firing. Altemus plans to publicly release this photo Wednesday.

Guess they decided to not release it after all

More images released during the press conference today, including the one Bob Austin mentioned in his post above, with the lander engine still blasting away.

So saying "break a leg" when wishing them luck was not a good idea...
