The Ansari X Prize (formerly the X Prize) was a States dollar|US$" target="_blank" >*10,000,000 prize, offered by the X PRIZE Foundation, for the first non-government organization to launch a reusable manned spacecraft into space twice within two weeks. It was modelled after early 20th-century aviation prizes, and aimed to spur development of low-cost spaceflight. The prize was won on October 4 2004, 47th anniversary of the Sputnik 1 launch, by the Tier One project using the experimental spaceplane SpaceShipOne.
Contest rules
The contest winner was to be the first team to launch a piloted spacecraft, carrying at least three crewmembers (or one human pilot and payload equivalent to two more), to an altitude of at least 100 kilometers (328,100 ft or 62.14 mi), and then repeat the feat using the same spacecraft within two weeks. Reaching orbit was not a goal, and so all the competitors aimed to make suborbital flights only. The spacecraft were permitted to land at the same site that they launched from. The 100 km target is the boundary of space as defined by the Fédération Aéronautique Internationale.
The two competitive flights were required to be made by the same vehicle. With the exception of propellant, no more than 10% of the vehicle could be replaced between flights; the rest of the vehicle must be reused. Even NASA's Space Shuttle falls short of this performance requirement, since it takes much more than two weeks to ready a given shuttle between flights. However, the space shuttle is an orbital, rather than sub-orbital spacecraft. The vehicle must be intact and theoretically reusable after the second flight, and the crew must return unharmed.
