SpaceX fires 11 engines of Starship Super Heavy booster ahead of test flight (video)




SpaceX is preparing its Starship Mars rocket for its first ever orbital test flight. It could be soon.

SpaceX ignited several Raptor engines on Booster 7 today, a prototype for Starship’s first stage Super Heavy rocket.

The static fire started at 2:42 PM EST (1942 GMT), and lasted 13 seconds. The test was captured by NASASpaceFlight (opens new tab) as well Rocket Ranch Boca Chica. It seemed to have been a strong one, indicating that it involved a large number of Booster 7 Raptors. SpaceX confirmed that Booster 7 had lit 11 of its engines shortly after the test.

SpaceX tested its Booster 7 Starship prototype on Nov. 29, 2022, firing 11 Raptor engines. (Image credit SpaceX via Twitter. Wednesday’s test marked the first static fire for Booster 7 in a year since Nov. 14, when it lit up 14 Raptors. 

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.

Booster 7 will be used in the orbital mission, as well as Ship 24, a prototype for Starship’s 165-foot (50 meter) tall upper stage. The Raptors are powering the upper stage. Ship 24 has already ignited all its engines in a Sept. 8 static firing.

Starship will become the most powerful rocket to fly by successfully completing an orbital flight. NASA’s Space Launch System megarocket currently holds that title. It was launched on Nov. 16, and kickstarted the agency’s Artemis 1 missions.

SpaceX is building Starship to transport cargo and people to Mars and to the moon. NASA is already a NASA customer. NASA selected the large vehicle to carry out at least two crewed moon missions for its Artemis program. It aims to establish an ongoing human presence on the moon by the 2020s.

Editor’s note – This story was updated at 4 :35 PM EST to clarify that SpaceX confirmed that 11 Raptors took part in the static flame.
