Minmus Taster Posted Thursday at 05:56 PM Share Posted Thursday at 05:56 PM 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 Quote Link to comment Share on other sites More sharing options...

No images yet but the lander seems to be on it's side again, darnit! I'd imagine this makes most of the payloads, which have to be deployed, useless.

darthgently Posted Thursday at 09:31 PM Share Posted Thursday at 09:31 PM 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 Quote Link to comment Share on other sites More sharing options...

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.

darthgently Posted Thursday at 09:44 PM Share Posted Thursday at 09:44 PM Clearly they need KSP overpowered reaction wheels to right the lander. Duh. We’ve all been there; sort of.

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 https://www.youtube.com/live/q-mMJxIttBc?si=u5as2ofvNxPk7XOy Quote Link to comment Share on other sites More sharing options...
tater Posted Thursday at 09:53 PM Author Share Posted Thursday at 09:53 PM Was just texting with my buddy at Johnson about this and my last text to him was: "At a certain point from intuitive machines, you wanna see the presser be them saying “Yeah we’re sorry, we kind of suck at this” " Quote Link to comment Share on other sites More sharing options...
darthgently Posted Thursday at 09:54 PM Share Posted Thursday at 09:54 PM (edited) 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 Edited Thursday at 10:03 PM by darthgently Quote Link to comment Share on other sites More sharing options...

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

If that image is corrected for actual vertical it looks like the software selected a bit of a slope to land on. Who knows? We need more info!

Minmus Taster Posted Friday at 05:47 PM Share Posted Friday at 05:47 PM (edited) 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.
