NASA Test-Fires RS-25 Engine for Most Powerful Rocket Ever
NASA is testing a rocket engine which it says could power the first manned missions to Mars.
The 7.5-minute test conducted at NASA’s Stennis Space Center is part of a series of tests designed to put the upgraded former space shuttle engines through the rigorous conditions they will experience during a launch. The tests are crucial to ensure the RS-25 engines will perform as needed.
The tests also support the development of a new controller, or “brain,” for the engine, which monitors engine status and communicates between the rocket and the engine, relaying commands to the engine and transmitting data back to the rocket.
