    NASA successfully tested the first deep space RS-25 rocket engine for 500s Mar 10, clearing a major milestone toward the next great era of space exploration. The next time rocket engine No. 2059 fires for that length of time, it will be carrying humans on their first deep-space mission in more than 45 years.

    The hot fire marked the first test of an RS-25 flight engine for NASA’s new Space Launch System (SLS), being built to carry humans on future deep-space missions, including an asteroid and Mars. 4 RS-25 engines will power the SLS core stage.
