Scott Manley analyses the crash of SN9:
Problem, crudely, was that one of the two Raptor engines meant to ignite for the landing maneuver doesn’t ignite. *Why* that happened is as yet unclear, but it looks like the engine (specifically the turbopump) was falling apart. The end result is that it seemed it hit the ground at about 120 mph, resulting in RUD (Rapid Unscheduled Disassembly). Ouch.
This remarkable slo-mo footage of the thing coming down is not to be missed:
It’s beautiful in a way. The fact that nobody was on board, and the fact that it wasn’t an example of taxpayer funded blaot, makes the loss non-tragic. Of course, if you work at SpaceX, your mileage may vary.
