At the SpaceX site in Boca Chica, Texas, for the first time, seven Raptor engines were launched simultaneously. The engine test was conducted as part of a prototype B7 Starship Super Heavy booster. The pressure in all engine working chambers was "lookin' good," as pointed out by the head of the company, Ilon Mack. The next test will be to refuel the fully assembled booster rocket.
Prior to that, the Super Heavy B7 booster prototype was tested during the start-up of one engine in August. It was during the static fire tests that there was a flash that caused the prototype to be repaired. Apparently nothing serious happened, which proved that yesterday's successful static fire tests at the same time of seven Super Heavy B7 engines.
The Starship 50 m high rocket will be driven simultaneously by six Raptor engines. The Starship 24 prototype test with all six engines was launched simultaneously on 8 September. At the next stage, the Starship rocket will be installed on an accelerator and first tested by a refuelling assembly. This will be the "wet" test of the world's largest 120 m high launch vehicle. It is planned that this event will take place in about two weeks.
In the meantime, the Super Heavy B7 accelerator prototype is being sent to the assembly hangar for routine repair/modernization, where it will be moved to the site for testing the Super Heavy B8 booster prototype. Ilon Mask hopes that the first orbital flight of the Starship prototype will take place before the end of the year, although the US Federal Civil Aviation Authority has not yet authorized it.
