  2. Nuclear power in space - Wikipedia

    en.wikipedia.org/wiki/Nuclear_power_in_space

    After the ban of nuclear weapons in space by the Outer Space Treaty in 1967, nuclear power has been discussed at least since 1972 as a sensitive issue by states. [8] Space nuclear power sources may experience accidents during launch, operation, and end-of-service phases, resulting in the exposure of nuclear power sources to extreme physical conditions and the release of radioactive materials ...

  3. Theoretical spacecraft propulsion - Wikipedia

    en.wikipedia.org/wiki/Theoretical_spacecraft...

    The fission sail is a type of spacecraft propulsion proposed by Robert Forward that uses fission fragments to propel a large solar sail-like craft. It is similar in concept to the fission-fragment rocket in that the fission by-products are directly harnessed as working mass, and differs primarily in the way that the fragments are used for thrust.

  4. Direct Fusion Drive - Wikipedia

    en.wikipedia.org/wiki/Direct_Fusion_Drive

    The captured radiated energy heats a He-Xe fluid that flows outside the plasma to 1,500 K (1,230 °C; 2,240 °F) in a boron-containing structure. That energy is put through a closed-loop Brayton cycle generator to transform it into electricity for use in energizing the coils, powering the RF heater, charging the battery, communications, and ...

    This fission occurs when atomic nuclei grab free neutrons and form heavy, but unstable, elements. When it comes to nuclear energy , human engineering and the rest of the universe are a bit at odds.

    Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.

  7. Nuclear salt-water rocket - Wikipedia

    However, if the use of NSWR began to rise, it would be possible to replace this with the cheaper isotopes 233 U or 239 Pu in either fission breeder reactors or (much better) nuclear fusion–fission hybrid reactors. These other fissiles would have the right characteristics to serve nearly as well, at a relatively low cost. [1] [8]

  8. Cosmic ray spallation - Wikipedia

    en.wikipedia.org/wiki/Cosmic_ray_spallation

    In contrast, the radioactive nuclide beryllium-7 falls into the same light element range but has a half-life too short for it to have been formed before the formation of the Solar System, so that it cannot be a primordial nuclide. Since the cosmic ray spallation route is the most likely source of beryllium-7 in the environment, that isotope is ...
