I don't have Twitter access right now but Athena seems (?) to be on the surface. They aren't sure what's happening but power is being generated. Maybe a repeat of last time :P

Yeah, their lander clearly has issues.

Indications are strong that Athena is “not in the correct attitude” on the surface.   Ouch.  A lot of ppl saying it is too skinny and tall but I’m betting on the guy who thinks they aren’t cancelling enough horizontal prior to touchdown.  Either touchdown is occurring before they think it should or there isn’t enough gimballed cosine thrust leftover for the horizontal cancellation after the required vertical deceleration takes its bite out of the budget or similar.   I have no particular reason for leaning this way other than it doesn’t seem like the lander is all that tall and skinny given the stance of the legs

I'm not actually sure what happened during the descent. I found the graphics provided during the landing stream confusing, which is a bad sign. I think it's mainly software related combined with the top-heavy design.

Clearly they need KSP overpowered reaction wheels to right the lander.  Duh.  We’ve all been there; sort of.  In our special KSP way, ha ha

In the ongoing live press conference, also on YouTube as well as X, they are saying the attitude ranging laser was not behaving well during descent so I’m leaning a bit further to the ground coming up quicker than perceived by the software perhaps

They just mentioned that this lander has much lower CoM than the previous with all the heavy stuff down low.  So they learned from the Sideways One lander.

I do not envy the IM ppl in the hot seats in this presser

I gotta say that it seems crazy to me they can’t verify the attitude.  A $0.50 cell phone accelerometer chip would probably do it in a pinch.  Shell out 20x that for “lunar grade” and it would still be a great deal.  I’m guessing on the cost but can’t be off horribly

Maybe they ARE using a $0.50 cell phone accelerometer, and then it got the moon's gravity field wrong.

lol.  Could be.  Though accelerometers are very simple and while the moon would have a lower magnitude it would still just point down.

Most cell phones tend to operate less than 400000km away from anything capable of receiving data, and do not require directional antennas to communicate most of their data

Intuitive Machines IM-2 On Its Side, Mission Ends | TalkOfTitusville.com

Athena is dead, it's landed on it's side in a crater and cannot recharge. They attempted to accelerate some of the science objectives but seemingly got no useful data. It's a bummer but better than a crash I suppose, good luck to Intuitive Machines next time.
