BAY ST. LOUIS, Miss. (AP) - NASA has successfully tested the rocket engine that may one day power men to Mars.
The test was conducted Friday at the Stennis Space Center in Hancock County.
Steve Wofford, with the SLS Liquid Engines Office at the Marshall Space Flight Center in Huntsville, Alabama, says the RS-25 was fired for 500 seconds. He says the test provided data on the engine controller unit and inlet pressure conditions.
Wofford says it was the first "hot fire" of an RS-25 engine since testing of space shuttle engines ended in 2009. Four of the engines will power the Space Launch System on future missions.
Testing will resume in April after a system that provides cool water for the test facility during a hot fire test is upgraded.
Eight more tests are planned.
