– This Startup Wants to Throw Satellites into Orbit With a Giant Centrifuge - ExtremeTech

Getting into space is hard, and one of the reasons is that it takes a lot of energy to break free of Earth's gravity. So far, the only way we've found to do that reliably is with rockets, but a startup called SpinLaunch has something else in mind. Using a giant vacuum chamber and a rotating hypersonic tether, the firm hopes to essentially throw satellites into orbit. SpinLaunch has just completed its first kinetic test launch by heaving a vehicle high into the atmosphere.
