[QUOTE="s-band, post: 1070270, member: 407744"] At the time of the LoS, an IMU failure was mentioned on the Youtube live feed. That is at the corner of the dog-leg in this plot where there is a gap. [URL]https://www.satellites.co.uk/forums/attachments/beresheet_1923-the_end_11-04-19_2280mhz-copy-png.123938/[/URL] There was also mention of re-start. More info near the end of this article [URL="https://www.nasaspaceflight.com/2019/04/beresheet-lunar-landing/"]Beresheet fails in historic lunar landing attempt for SpaceIL – NASASpaceFlight.com[/URL] Comms returned after that. I guess that the reduced rate of change of Doppler after the failure suggests it stopped slowing down at the previous rate i.e. engine not running. Impact was at ~134m/s vertical. I've not seen anything from NASA's LRO which they were using to observe engine gas during landing [/QUOTE]
