Fusion nuclear pulse propulsion is one approach to using nuclear fusion energy to provide propulsion. Fusion's main advantage is its very high specific impulse, while its main disadvantage is the (likely) large mass of the reactor. A fusion rocket may produce less radiation than a fission rocket, reducing the shielding mass needed.
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 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 chemical rocket. In an NTR, a working fluid , usually liquid hydrogen , is heated to a high temperature in a nuclear reactor and then expands through a rocket nozzle to create thrust .
NASA will test a nuclear-powered rocket for space travel. The technology could speed up a manned trip to Mars from the current seven-month minimum to 45 days.
In mid-1958, NASA replaced the Air Force [16] and built Kiwi reactors to test nuclear rocket principles in a non-flying nuclear engine. [17] With the next phase's Nuclear Engine for Rocket Vehicle Application ( NERVA ), NASA and AEC sought to develop a nuclear thermal rocket for "both long-range missions to Mars and as a possible upper-stage ...
Specifically, nuclear fusion won't help the world reach its 2030 net-zero targets. It may start to come into play by 2050 . “I still think we're decades away,” Dominguez said.

Direct Fusion Drive (DFD) is a conceptual, low radioactivity, nuclear-fusion rocket engine, designed to produce both thrust and electric power, suitable for interplanetary spacecraft. The concept is based on the Princeton field-reversed configuration reactor , invented in 2002 by Samuel A. Cohen.
