A nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction replaces the chemical energy of the propellants in a...

A nuclear electric rocket (more properly nuclear electric propulsion) is a type of spacecraft propulsion system where thermal energy from a nuclear reactor...

NERVA (Nuclear Energy for Rocket Vehicle Applications), a US nuclear thermal rocket program Project Rover, an American project to develop a nuclear thermal...

Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust. The energy required can either come from the propellants themselves...

In a traditional nuclear photonic rocket, an onboard nuclear reactor would generate such high temperatures that the blackbody radiation from the reactor...

and much larger and more complex rockets. Fusion nuclear pulse propulsion is one approach to using nuclear fusion energy to provide propulsion. Fusion's...

mid-1950s. Project Orion was the first serious attempt to design a nuclear pulse rocket. A design was formed at General Atomics during the late 1950s and...

The Nuclear Engine for Rocket Vehicle Application (NERVA; /ˈnɜːrvə/) was a nuclear thermal rocket engine development program that ran for roughly two...

necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are...

Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion...

A pulsed nuclear thermal rocket is a type of nuclear thermal rocket (NTR) concept developed at the Polytechnic University of Catalonia, Spain, and presented...

the nuclear thermal rocket ( I sp {\displaystyle I_{\text{sp}}} ~ 103 sec) due to temperature limitations of the solid. However, the antimatter energy conversion...

The nuclear salt-water rocket (NSWR) is a theoretical type of nuclear thermal rocket designed by Robert Zubrin. In place of traditional chemical propellant...

photon rockets are proposed to be powered by onboard generators, as in the nuclear photonic rocket. The standard textbook case of such a rocket is the...

Alternatively, radioisotopes may be used in a radioisotope electric rocket, in which energy from nuclear decay is used to generate the electricity used to power an...

the nuclear thermal rocket is to cut the journey time to Mars in half. In May 1946, the U.S. Air Force launched the Nuclear Energy for Propulsion of Aircraft...

through a rocket nozzle to produce thrust. Steam rockets are usually pressure fed, but more complex designs using solar energy or nuclear energy have been...

temperature in a nuclear reactor, and then expands through a rocket nozzle to create thrust. The nuclear reactor's energy replaces the chemical energy of the reactive...

abilities of current technologies. In traditional nuclear thermal rocket and related designs, the nuclear energy is generated in some form of reactor and used...
