SpaceX fires 11 engines of Starship Super Heavy booster ahead of test flight (video) - Space.com

SpaceX is prepping Booster 7 for an orbital test flight.

SpaceX continues to prep its Starship Mars rocket for its first-ever orbital test flight, which could be coming soon.

During a "static fire" test today (Nov. 29) at its South Texas facility, SpaceX ignited multiple Raptor engines on Booster 7, a prototype of Starship's first-stage Super Heavy rocket.

Video captured by NASASpaceFlight (opens in new tab) and Rocket Ranch Boca Chica (opens in new tab) showed the test to be a powerful one, suggesting it involved a healthy proportion of Booster 7's 33 Raptors.

That turned out to be the case; shortly after the test, SpaceX confirmed via Twitter (opens in new tab) that Booster 7 lit up 11 of its engines.

Wednesday's test was the first static fire for Booster 7 since Nov.

Shortly after that trial, SpaceX founder and CEO Elon Musk said that the company planned to perform just one or two more static fires (opens in new tab) with Booster 7 before launching an orbital test flight — the first ever for the Starship program.

A successful orbital flight will make Starship the most powerful rocket ever to fly.
