Aerojet Rocketdyne tests RS-25 engine in progression of NASA space launch to Mars

Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), has completed additional testing of NASA´s Space Launch System (SLS) RS-25 development engine 0528, at NASA Stennis Space Center in Mississippi, the company said.

The company said the engine ran for a duration of 420 seconds over power ranges from 80 to 111 percent rated power level.

Last year, Aerojet Rocketdyne resumed RS-25 engine testing to ensure that the engines will withstand the demanding operational environment required by SLS. Following the recent test, three RS-25 engines have accumulated 5,468 seconds of test time and engine 0528 has been tested for 1,263 seconds.

Aerojet Rocketdyne is supporting the propulsion and power requirements for the six elements for Mars: SLS; Orion; solar electric propulsion (SEP); deep space habitats; entry, descent and landing systems; and ascent vehicles. The capabilities exist today for each of these elements.
