Специалисты компании SpaceX вчера завершили тесты многоразовой системы Starship (первая ступень Super Heavy B10, вторая Starship S28). В общем-то всё готово к полёту, ожидается только обновление лицензии от Федерального управления гражданской авиации США (FAA).
При этом SpaceX уже назначила новый (третий) испытательный запуск многоразовой системы Starship с космодрома Starbase (Бока-Чика) на 14 марта (четверг) в 15:00 по московскому времени.
The third flight test of Starship could launch as soon as March 14, pending regulatory approval.
A live webcast of the flight test will begin about 30 minutes before liftoff, which you can watch here and on X @ SpaceX. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to stay tuned to our X account for updates.
Starship’s second flight test achieved a number of major milestones and provided invaluable data to continue rapidly developing Starship. Each of these flight tests continue to be just that: a test. They aren’t occurring in a lab or on a test stand, but are putting flight hardware in a flight environment to maximize learning.
The third flight test aims to build on what we’ve learned from previous flights while attempting a number of ambitious objectives, including the successful ascent burn of both stages, opening and closing Starship’s payload door, a propellant transfer demonstration during the upper stage’s coast phase, the first ever re-light of a Raptor engine while in space, and a controlled reentry of Starship. It will also fly a new trajectory, with Starship targeted to splashdown in the Indian Ocean. This new flight path enables us to attempt new techniques like in-space engine burns while maximizing public safety.
This rapid iterative development approach has been the basis for all of SpaceX’s major innovative advancements, including Falcon, Dragon, and Starlink. Recursive improvement is essential as we work to build a fully reusable transportation system capable of carrying both crew and cargo to Earth orbit, help humanity return to the Moon, and ultimately travel to Mars and beyond.
