SpaceX Tests Highest Pressure Rocket Engine In History

Under Pressure

SpaceX CEO Elon Musk says that his space company’s Raptor engine just aced an important pressure test — and set a world record.

The company is planning to use six of the engines to eventually get its massive Starship spacecraft off the ground, while a Super Heavy booster itself will likely need closer to 40.

“Raptor engine just reached 330 bar chamber pressure without exploding!” Musk exclaimed in a Monday tweet. That’s quite a lot of pressure, even for a rocket engine, surpassing the previous record of the Soviet’s RD-701 engine from the 1980s, as Teslarati reports.
