The first developmental test series for NASA’s “super” engines to power its mega Space Launch System rocket have been completed. The rocket will be used on missions to go deeper into space than ever before, including Mars.

The late August test on the RS-25 engine ran for 535 seconds. (Watch a NASA video of the test.)

"The completion of this test series is an important step in getting SLS ready for the journey to Mars," says Steve Wofford, engines manager at NASA's Marshall Space Flight Center, in a statement.

NASA says the engine gives 77-tonnes SLS a proven, high performance and affordable main propulsion system.

Four RS-25 engines will help power the SLS core stage during launch. The engines will provide about 2 million pounds of thrust when firing simultaneously at 109% of their operating level.
