Look, going anywhere into space is not easy. With everything going for it, SpaceX has had it’s own disasters. 5 days before China’s successful Tiāngōng 2 launch, the SpaceX Falcon 9 rocket blew up on the launch pad.
Nobody got hurt, but it was a loss of over a quarter billion dollars.
The explosion took the AMOS-6 satellite with it. This was a Facebook project to provide 14 African countries with free Internet access.
The root cause at this point appears to be the a large breach in the cryogenic helium system.
