Voo de ensaio orbital do Starship da SpaceX
February 11, 2022 - O primeiro voo orbital do Starship da SpaceX – o mais poderoso foguetão alguma vez construído – pode chegar daqui a meses. A NASA escolheu o Starship totalmente reutilizável para voltar a levar astronautas à Lua.
SN20 and its first stage booster are set for an orbital launch as soon as March from SpaceX’s testing facility in Boca Chica, Texas. The landmark liftoff is awaiting a U.S. Federal Aviation Administration environmental review of the Starbase facility.
The fully reusable Starship system will send people and cargo to the moon, Mars and other distant planets. Starship prototypes have flown before, but only reaching maximum altitudes of around 10 kilometres. Those previous launches involved Starship vehicles with no more than three Raptor rocket engines, and none of them lifted off atop a Super Heavy booster.
Booster 4’s 29 massive Raptor engines will fire for 169 seconds before releasing Starship to fly powered by six engines -- three sea-level engines for atmospheric flight and three large vacuum-optimized Raptors for high performance in space.
Starship will soar into orbit and splashdown in the Pacific Ocean, 100km northwest of the Hawaiian island of Kauai.
SpaceX CEO Elon Musk says a key goal is to ensure that the Starship rockets are reusable, and future tests will see both stages return to the launch pad rather than splashdown in the ocean. Musk says SpaceX could launch a Starship to the moon “probably sooner” than 2024.
