SpaceX fires up multiple Super Heavy engines


As part of a static test at its Starbase site in Boca Chica, Texas, SpaceX proceeded on Tuesday to the simultaneous ignition of several engines of a prototype of the Super Heavy booster of its future heavy launcher Starship.

In all, these are 11 Raptor 2 engines (with a thrust of 230 tons each) which were lit for a period of about twelve seconds. On November 14 and for about ten seconds, SpaceX had ignited 14 Raptor 2 engines out of the 33 that will equip the first floor of Starship.

Following the static test of November 14, Elon Musk said that the next test would be a burn of approximately 20 seconds with maximum oxygen filling to test autogenous pressurization.

Super Heavy B7 et Starship S24

The firing with the 11 Raptor 2 engines of the Booster 7 (B7) prototype was ultimately shorter than initially planned. After this test, the boss and founder of SpaceX had raised the possibility of another static test, then the long-awaited orbital flight attempt.

Not sure now that such a schedule will be kept and all the more so without a complete test of the ignition of the 33 engines of the Super Heavy prototype. For the Starship (upper stage), an S24 prototype has already experienced ignition of all of its 6 engines during a static test in September.

It is with the Starship S24 and Super Heavy B7 prototypes that the first orbital flight of Starship should take place. During this flight of about 9 minutes, the second stage will be placed in low orbit and will make an atmospheric re-entry for a water landing, but without recovery with a barge.

Orbital flight before 2023?

With successful orbital flight, Starship would become the most powerful rocket to fly. A performance that now and recently belongs to the SLS (Space Launch System) rocket, following the takeoff of NASA’s Artemis I mission.

For Starship, SpaceX aims for the Moon, including at least two manned missions for a moon landing as part of the Artemis program, and even the planet Mars. It will first be necessary to succeed in the orbital flight stage, which is falling behind schedule.
