Starship: SpaceX passes static ignition test of launch vehicle Raptor engines

It’s an encouraging step: Yesterday, SpaceX successfully passed the static ignition test of its large Starship launcher (Booster 7 prototype). In particular, 7 second generation Raptor engines were fired at the same time, the largest simultaneous ignition of a second generation Raptor. Eventually, when the rocket is finally ready to take off, no less than 33 Raptor engines will launch a stream of energy to lift the starship off the ground. Note that 33 engines are placed on the Super Heavy (launcher) and 6 other engines on the starship (whose name usually includes the launcher + second stage).

Elon Musk was, of course, pleased with this success, adding that the Booster 7 will return to the barn for further improvements. The next checkpoint is the “wet dress rehearsal” dress rehearsal, a global firing test that runs from tank filling to countdown and allows you to view all stages of takeoff. It will then proceed to turn on 33 engines at the same time. Only after all these steps will Starship really be ready for takeoff. SpaceX hasn’t given a launch window yet, but if all goes well, Starship’s first test flight could be completed before the end of the year, and most likely in the first quarter of 2023.
