SpaceX is preparing Starship Super Heavy booster for a 33-engine static fire test

Musk posted a photo of Booster 7 being held by Mechazilla’s arms, with the caption “Mechazilla loads Starship on launchpad.”

Earlier this month, SpaceX fired up both Starship and Booster 7 for “static fire” engine tests that saw them each fire a single Raptor engine. Booster 7 only had 20 of its 33 total next-gen Raptor engines attached at the time, meaning this was the first time the booster was on the launch pad with its full arsenal of engines.

After the engine tests earlier this month, SpaceX used Mechazilla to lift Booster 7 and move it to a processing base at Starbase. That’s where engineers fitted the 13 extra Raptors before Booster 7 made its way back to the launch pad. Now, SpaceX is preparing for more static fire tests, with one of them set to fire up all 33 Raptor engines on Booster 7 at the same time. Once that happens, SpaceX will be a step closer to performing its first-ever orbital flight of Starship — the massive milestone could take place as soon as next month.

A new era for space exploration

Starship is SpaceX’s next-generation rocket. It is designed with a view to drastically reducing the cost of consecutive launches, enabling it to send astronauts to Mars. That massive cost reduction comes from the fact that it will be the first fully reusable orbital rocket. Several customers have also penned agreements with SpaceX for Starship flights, including NASA and Japanese billionaire Yusaku Maezawa. Last year, NASA awarded SpaceX a $2.9 billion contract to send astronauts back to the surface of the moon.
