SpinLaunch is a stealth space catapult startup that aims to creates a much cheaper and sustainable way to get things like satellites from earth into space without chemical propellant. Using a catapult would sidestep the heavy fuel and expensive booster rockets used by companies like SpaceX and Blue Origin. SpinLaunch plans to use a centrifuge spinning at an incredible rate inside a vacuum that reduces friction. All that momentum is then harnessed to catapult a payload into space at speeds one source said could be around 3000 miles per hour. With enough momentum, objects could be flung into space on their own. Alternatively, the catapult could provide some of the power needed with cargo being equipped with supplemental rockets necessary to leave earth's atmosphere.
