RS-25 Engine Propulsion Testing
NASA’s Space Launch System (SLS), the most powerful rocket in the world, will be powered by RS-25 engines that combine proven performance with advanced engineering and technology.
As a member of NASA’s power and propulsion team, Bastion has contributed to completing numerous hot fire tests of the RS-25 engine on the A-1 stand at Stennis Space Center. The SLS will be powered by four RS-25 engines for the core stage, each one provided just shy of 420,000 lbs. of thrust at sea level. “We’ve conducted the RS-25 engine tests during this remarkable development program to modernize manufacturing, on-ramp additive manufacturing, and reduce cost of the RS-25 engines for the Space Launch System,” said Johnny Heflin, manager for the SLS Liquid Engines Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These tests are helping us ensure the success of not only the upcoming flight of Artemis I but also of future missions that will lead to long-term exploration of the Moon.”
