RS-25 Main Engine Controllers Tested for SLS Debut
STENNIS SPACE CENTER, Miss.,
"The SLS rocket will enable missions no other current rocket can, such as landing humans on Mars and sending large science payloads to other planets in record time," said
New engine controllers are a central technology upgrade that these engines are receiving. These controllers weigh less, use less power and have fewer parts, but are more robust than their shuttle era counterparts and provide two times the reliability. The flight controller is the "brain" of the engine, translating the vehicle's commands into action while monitoring the health of the engine.
"The upgraded RS-25 engines are just one example of how the country is preparing a new course for deep space exploration," said
EM-1 is the first launch of the SLS and upgraded RS-25 engines; it is also the first integrated test of SLS and the Orion spacecraft. During the three-week mission, the Orion spacecraft will travel in a distant retrograde orbit around the moon and return safely back to Earth.
