NASA artist rendering, from 1999, of the Project Orion pulsed nuclear fission spacecraft. Project Orion was a study conducted in the 1950s and 1960s by the United States Air Force, DARPA, [1] and NASA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft.
The knowledge gained provided data to prevent nuclear yields in case of accidental detonations—for example, in a plane crash. The John shot on July 19, 1957, was the only test of the Air Force's AIR-2A Genie rocket with a nuclear warhead. [3] It was fired from an F-89J Scorpion fighter over Yucca Flats at the Nevada National Security Site.
Nuclear pulse propulsion or external pulsed plasma propulsion is a hypothetical method of spacecraft propulsion that uses nuclear explosions for thrust. [1] It originated as Project Orion with support from DARPA , after a suggestion by Stanislaw Ulam in 1947. [ 2 ]
Nuclear power sources could also be used to provide the spacecraft with electrical power for operations and scientific instrumentation. [12] Examples: NERVA (Nuclear Energy for Rocket Vehicle Applications), a US nuclear thermal rocket program; Project Rover, an American project to develop a nuclear thermal rocket. The program ran at the Los ...
A fusion rocket may produce less radiation than a fission rocket, reducing the shielding mass needed. The simplest way of building a fusion rocket is to use hydrogen bombs as proposed in Project Orion, but such a spacecraft would be massive and the Partial Nuclear Test Ban Treaty prohibits the use of such bombs. For that reason bomb-based ...
The United States and Russia are set to face off over nuclear weapons in space on Wednesday at the United Nations Security Council, which is due to vote on a U.S.-drafted resolution calling on ...
Starfish Prime was a high-altitude nuclear test conducted by the United States, a joint effort of the Atomic Energy Commission (AEC) and the Defense Atomic Support Agency. It was launched from Johnston Atoll on July 9, 1962, and was the largest nuclear test conducted in outer space, and one of five conducted by the US in space.
The 1 December 1958 issue of Aviation Week included an article, "Soviets Flight Testing Nuclear Bomber", that claimed that the Soviets had greatly progressed a nuclear aircraft program: [10] "[a] nuclear-powered bomber is being flight tested in the Soviet Union. Completed about six months ago, this aircraft has been flying in the Moscow area ...
