On March 23, 1962 a Model of the Orion pulse propultion spacecraft General Power was
presented to President Kennedy
Project Orion was a 1950s-60s study by the U.S. Air Force, DARPA, and NASA to explore the feasibility of a nuclear pulse spaceship propelled by atomic explosions. Initially, the vehicle was designed to take off from Earth, but later models were intended for use only in space. The project, led by General Atomics and physicists like Wernher von Braun and Freeman Dyson, included non-nuclear tests and proposals for missions such as a Mars trip.
The idea of nuclear pulse propulsion was first proposed in 1946 by Stanislaw Ulam, with early calculations done in 1947. In 1955, Ulam co-authored a paper on using nuclear fission bombs to propel vehicles in space. DARPA sponsored the project starting in 1958 with a $1 million budget, and NASA also contributed funding. However, support waned by late 1959 when General Dynamics withdrew, and the project struggled to find a clear military or civilian use.
By 1964, Project Orion was canceled due to the 1963 Partial Test Ban Treaty, which prohibited nuclear explosions in space, and NASA’s decision to focus on non-nuclear space missions.
