Space Launch Start-Up Just Used A Giant Centrifuge To Fling A Projectile Into The Upper Atmosphere

A U.S. space launch start-up has, for the first time, demonstrated a kinetic-based system that’s intended one day to put small spacecraft into orbit. The SpinLaunch concept, which feels ripped right from the classic age of science fiction, is based around a vacuum-sealed centrifuge that spins an unpowered projectile at several times the speed of sound before releasing it, hurling it into the upper atmosphere, and ultimately into orbit.
