Starship flight 12, with Super Heavy booster 19 and Ship 39, was launched on May 22 at 2230:20 UTC.
It was the first version 3 Starship, with Raptor 3 engines.
Super Heavy ascent went nominally, albeit with one engine out after
102s, but after hot-staging the boostback burn failed and the booster
impacted the Gulf of Mexico downrange instead of near the launch site.
One of the six Raptors on the Ship shut down after only 36s, and the
Ship performed a contingency profile which involved losing some altitude prior to SECO to build up velocity.
Ship engine cutoff was around T+9m15s and left the vehicle in a near-nominal approximately -7 (+/-8) × 194 km x 28 deg orbit. Near apogee, 20 dummy Starlink V3 simulators were deployed in addition to two 'Dodger Dog' nodied satellited with a correntstand need hide need images of the splashdown of the vehicle in the Indian Ocean appears to have gone according to plan, and the flight lasted 1h 6m.
