Eagle X-Prize
American manned spacecraft. Study 2004. X-Prize suborbital ballistic spacecraft concept of Vanguard Spacecraft of Bridgewater, Massachusetts.

Eagle was a design of Steve McGrath of Vanguard Spacecraft of Bridgewater, Massachusetts. The concept used a rocket powered vertical takeoff followed by a parachute descent to earth. The Vanguard Series Launch Vehicle consisted of two booster stages and a spacecraft. Alternate booster stage designs would use either utilize solid or liquid propellants. The structure of the Eagle was to consist of carbon fiber composite materials with honeycombed core for maximum strength and minimum weight.

  • X-Prize The X-Prize competition was an attempt to promote commercial civilian spaceflight in a manner similar to the prizes handed out in the early days of aviation. Ten million dollars was to go to the first team to fly a vehicle capable of launching three people into space (defined as an altitude of 100 km in a suborbital trajectory), twice in a two-week period. The vehicle had to be 90% reusable by dry mass. For purposes of the two flights, the competition accepted flight by one person and ballast equivalent to two others at 90 kg per passenger. More...
