$begingroup$
I was watching the livestream of the SpaceIL team when they were attempting to land Beresheet on the Moon. As near as I can remember, at around an altitude of 15km above the surface, the SpaceIL control team suddenly lost contact with both the spacecraft and NASA in the US. Communications with the lander picked up when the lander was about 2km above the surface and then lost again when they were unable to stop the descent. I don't remember them reestablishing contact with NASA.
Do we know what caused these communication outages? Was it a problem on the Beresheet side or Earth side? (Or am I totally misremembering what happened?)

Earlier in the stream they mentioned a glitch or unusual behavior with the IMU, but contact remained.
Later in the burn the engine shutdown unexpectedly and they immediately reset the spacecraft to restore regular operation. This made the telemetry uplink drop out for a moment, before returning. It's not clear to me from the stream if the engine ever started again, and presumably the next signal loss is impact.
