The prototype of the Starship transport system of SpaceX by the American engineer and entrepreneur Elon Musk made a hard landing during the next tests. The corresponding broadcast was conducted on Twitter.
According to Ars Technica editor Eric Berger, the 11th prototype spacecraft (SN11) was tested, which, during maneuvers, rotated around its axis somewhat more intensively than during testing of previous products. Musk said the Starship crashed, likely due to problems with the second Raptor engine. In March Musk blasted the tenth prototype starship (SN10) spacecraft earlier in the month due to the low thrust of its Raptor engine, likely due to partial ingress of helium from the fuel tank.
In December 2020, the developer of the Merlin and Raptor rocket engines, Thomas Mueller, revealed that he had left SpaceX.
In March 2018, Musk announced that the Raptor would receive the largest thrust-to-weight ratio of any engine ever.
