SpinLaunch is developing a kinetic energy space launch system that reduces dependency on traditional chemical rockets, with the goal of significantly lowering the cost of access to space while increasing the frequency of launch. The technology uses a vacuum-sealed centrifuge to spin a rocket and then hurl it to space at up to 5,000 miles per hour (8,000 km/h). The rocket then ignites its engines at an altitude of roughly 200,000 ft (61,000 m) to reach orbital speed of 17,500 miles per hour (28,200 km/h).
