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 8,000 kilometres per hour (5,000 mph). The rocket then ignites its engines at an altitude roughly 200,000 feet (61 km) to reach orbital speed of 17,500 miles per hour (28,200 km/h). If successful, the acceleration concept is projected to be both lower cost and to use much less power, with the price of a single space launch reduced by a factor of 20 to under US$500,000
