I said most of the kernels on the NAIF site don't model the landing. The one I extracted the data from does at least at some level, otherwise I wouldn't have bothered with it.

Download is not working for me neither.

(for example, powered descent duration can't vary by much because you run out of fuel if it goes too long and you crash if it goes too short

this remembers me of something...

how do Phoenix and Insight prevent Schiaparelli final event from happening?
And by the way, recorded data on Phoenix show and incredibly wrong modelization of Pitch, Roll and Yaw for Phoenix:
https://ntrs.nasa.gov/archive/nasa/casi.ntr...20080034645.pdf

(fig. 6, 7, 8).

By the way, is anything similar to Phoenix raw data available for unfortunate Schiaparelli mission? Or was it supposed to upload them once landed?

Has it occurred to you that maybe the problem is your interpretation of the data, not that they are "incredibly wrong"?

There was some realtime downlink of Schiaparelli data, I think it's described in the failure report. I'd be very surprised if it was online in raw form.

Here's the Insight dump with 1-second intervals.
