QUOTE (Phil Stooke @ May 23 2023, 07:30 AM) *
Not north of the crater as the previous analysis suggested.

With all due respect to AMSAT, I'm not seeing any error bars on their analysis, I'm not sure where they got the orbit data, I don't know what coordinate system they're using, there are some assumptions made, etc, so I wouldn't have assigned very high confidence to their result in the first place.

They do say their result assumes a vertical pitch angle and note "The landing could also have been in Atlas crater but at a pitch angle of -86.7° rather than -90° which is vertical down."

That's right. Scott Tilley also expressed reservations about the analysis:

Analysis of the failure has been released
As usual for the last few (non-China) landings, a software issue...
