Nuclear thermal rocket - Wikipedia
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 .
Space Nuclear Propulsion - NASA
2024年10月21日 · NASA and DARPA intend to demonstrate a nuclear thermal propulsion rocket engine in space as soon as 2027. In February 2021, NASA and the Department of Energy (DOE) requested proposals from industry for preliminary reactor design concepts for a nuclear thermal propulsion system.
Nuclear propulsion - Wikipedia
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
Nuclear power in space - Wikipedia
Nuclear power in space is the use of nuclear power in outer space, typically either small fission systems or radioactive decay for electricity or heat. Another use is for scientific observation, as in a Mössbauer spectrometer .

2023年1月25日 · NASA has revealed plans to create a nuclear-powered rocket that could send astronauts to Mars in just 45 days. The agency, which has partnered with the Pentagon’s Defense Advanced Research...
Nuclear Thermal Propulsion Systems - Glenn Research Center
2023年12月18日 · Typically when the term “Nuclear Thermal Propulsion” (or NTP) is used, it is in reference to in-space propulsion systems that rely upon a low molecular weight (typically hydrogen) fuel that flows through a reactor to generate heat due to the nuclear fission processes and eventual thrust.
NASA, DARPA Will Test Nuclear Engine for Future Mars Missions
2023年1月24日 · NASA and the Defense Advanced Research Projects Agency (DARPA) announced Tuesday a collaboration to demonstrate a nuclear thermal rocket engine in space, an enabling capability for NASA crewed missions to Mars.
Nuclear Thermal Propulsion: Game Changing Technology for Deep ... - NASA
2018年5月25日 · New work on Nuclear Thermal Propulsion builds upon NASA’s Nuclear Engine for Rocket Vehicle Application (NERVA) program of the 1960s. This is an explanatory drawing of the NERVA thermodynamic nuclear rocket engine. Potential advantages of NTP for human Mars missions include reduced transit time to the planet and back to Earth.
6 Things You Should Know About Nuclear Thermal Propulsion
NASA wants to send astronauts to Mars, and they could do it with nuclear-powered rocket engines. Nuclear thermal propulsion (NTP) systems aren’t new, but they could significantly reduce travel times and carry greater payloads than today’s top chemical rockets — giving humans a great chance of exploring deep space.
