SpaceX Starship launched 3 Raptor engines in one day



At around 12:30 pm CST (UTC-6), the SpaceX Starship prototype serial number 9 (SN9) ignited the Raptor engine for the second time, and then ignited the Raptor engine again at 2:22 pm, and ignited again in the afternoon at 3:37 pm The third one.

All three tests are very brief and reflect SN9’s first static shot, which ended earlier than SpaceX planned on January 6. In the end, despite this, according to SpaceX CEO Elon Musk (Elon Musk) after the first brief comment, the brief static shooting was clearly intentional.

More importantly, this is the first time once SpaceX completed (or even tried) two “starship” static shots in one day, let alone two hours. For its part, the fact that SpaceX is willing to conduct two static shots within two hours can confirm that the first test was successful, because the company will definitely not risk a vehicle breakdown by doubling down on failed or aborted tests Risk, unless it can immediately determine the root cause.

According to Musk, SpaceX is “exercise engine start [today]”Three “starting points” have been produced so far. The description reflects the extremely short static fires observed today. The need for specific ignition-related tests on SN9 also seems to imply that Starship’s first test may have ended prematurely due to Raptor ignition issues

In the end, less than 90 minutes after the second static fire that day, Starship SN9 ignited one or more of its three Raptor engines for the third time around 3:37 pm. Musk quickly confirmed that the third successful (or at least non-destructive) static shot had been completed.

Musk recently stated that SpaceX is now disassembling and installing SN9 to protect the cushions and aircraft for inspection. If these inspections finally conclude that the Starship SN9 and its three Raptors are in good condition after an unprecedentedly busy day of static fire testing, then SpaceX can turn the rocket around for 12.5 kilometers as early as June 14 or 15. (7.8 miles) launch attempt.
