NASA fires up engine to take astronauts to Mars

  • As part of its ambitious Space Launch System (SLS), the US space agency has successfully tested an engine that will help propel astronauts on future deep-space missions, including Mars.

    The 535-second test of RS-25 rocket engine at NASA's Stennis Space Center near Bay St. Louis, Mississippi, was aimed to collect engine performance data, the US space agency said in a statement.

    An initial 77-tonne SLS configuration will use four RS-25 engines for the core stage, along with two five-segment solid rocket boosters, providing more lift to orbit than any current launch vehicle. (Source: IANS)
