Nuclear-powered rockets are not used to lift off the Earth. Nuclear thermal rockets can provide great performance advantages compared to chemical propulsion systems. Nuclear power sources could also be used to provide the spacecraft with electrical power for operations and scientific instrumentation. [12] Examples:
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.
Examples of concepts that use nuclear power for space propulsion systems include the nuclear electric rocket (nuclear powered ion thruster(s)), the radioisotope rocket, and radioisotope electric propulsion (REP). [6] One of the more explored concepts is the nuclear thermal rocket, which was ground tested in the NERVA program.
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 ]
NASA will partner with the U.S. military's research and development agency, DARPA, to develop a nuclear thermal propulsion engine and launch it to space "as soon as 2027," NASA administrator Bill ...
To enable cooperation with the AEC and keep classified information compartmentalized, the Space Nuclear Propulsion Office (SNPO) was formed at the same time. The 1961 NERVA program was intended to lead to the entry of nuclear thermal rocket engines into space exploration. Unlike the AEC work, which was intended to study the reactor design ...
Lockheed Martin was awarded a contract by federal agency DARPA in partnership with NASA to build out an experimental nuclear-powered spacecraft that aims to make trips to the moon and Mars more ...
TEM (Russian: Транспортно-энергетический модуль, "transport and energy module\unit", NPPS in English) is an under development nuclear propulsion spacecraft with the intention to facilitate the transportation of large cargoes in deep space. [2]
