Rocket engine race to the Moon and Mars
6 May
Entrepreneur Elon Musk has been touting tests of his new Raptor rocket engine. The engine is due to power his SpaceX company’s booster on flights to the Moon and beyond. The Raptor engine is still under test, whereas the alternative Russian RD-180 motor has successfully launched hundreds of rockets into space. The two rocket engines are vying to be used on man’s first flight to Mars, and for return flights to the Moon.
