The billionaire space race is the rivalry among entrepreneurs who have entered the space industry from other industries - particularly computing. This private industry space race of the 21st century involves sending rockets to the ionosphere (mesosphere and thermosphere), orbital launch rockets, and suborbital tourist spaceflights. Today, the billionaire space race is primarily between three billionaires and their respective firms: Jeff Bezos's Blue Origin, which is seeking to establish an industrial base in space. Richard Branson's Virgin Group (through Virgin Galactic and Virgin Orbit), which seeks to dominate space tourism, low-cost small orbital launch vehicles, and intercontinental sub-orbital spaceflight. Elon Musk's SpaceX, which seeks to colonize Mars as well as provide satellite-based internet through its Starlink project. Prior to his death in 2018, Paul Allen was also a major player in the billionaire space race through the aerospace division of his firm Vulcan. Allen sought to reduce the cost of launching payloads into orbit. From Wikipedia
