  • NASA tests rocket engine intended to take humans to Mars

    TWELVE million horsepower — what a ride. This is the engine that may take us to Mars, and it’s just been fired up for the first time at a NASA testing facility.
    The RS-25 engine was fired up at the Stennis Space Centre in Mississippi. It burned for nine minutes, chewing through nine swimming pools worth of fuel.
    “It is the most complicated rocket engine out there on the market, but that’s because it’s the Ferrari of rocket engines,” NASA propulsion engineer Kathryn Crowe said.

    When you're looking at designing a rocket engine, there are several different ways you can optimise it. You can optimise it through increasing its thrust, increasing the weight to thrust ratio, or increasing its overall efficiency and how it consumes your propellant. With this engine, they maximised all three.
    It’s better to give than to receive. Especially advice
