    Cool Why is NASA still using Russian RD-180 rocket engines?

    Because we stopped making good ones of our own.
    Unlike the gas-generator engines used in the US Space Shuttle program and the Apollo Moon landings, the Soviet ones did not let the exhaust from the rocket fuel go to waste. Instead, the exhaust from the so-called pre-burners (used to send fuel and oxygen into the main combustion chamber under high pressure to burn them there and generate thrust) was re-injected into the main combustion chamber, giving the engine more power.
    Civilian companies are now stepping up.
    Four companies are now competing to build a new, domestic US rocket engine: Elon Musk’s SpaceX, Jeff Bezos’ Blue Origin, the ULA and Northrop Grumman. SpaceX and Blue Origin already announced that they are developing and testing their own engines, based on technologies similar to those used in RD-180.

    Because Obama destroyed NASA.

    In some one ways I hope the soviets come back so that maybe if we had a super power enemy again, we could get back on the right path.
