Elon Musk indicates that the SN10 engines lacked thrust. The rocket landed at 10 m/s, damaging some parts. It also used « Helium in header » to atone for SN8’s explosion, but that was also problematic.
Less than a week ago, SpaceX almost succeeded in completing a flawless test flight for the Starship SN10. And things were looking up until a few moments after a successful ascent and touchdown back to earth. Just like the SN8 and SN9 predecessors before it, SN10 too met a fiery, explosive ending. It was unclear why the rocket exploded, especially after it had touched down and remained stationary for close to a minute. SpaceX founder and CEO, Elon Musk, has now cleared up some confusion on that front.
