  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 ...

    Nuclear fission is a substantial part of the world’s energy mix, but out in the broader universe, fission is much harder to come by. Until now. ... according to Space.com. When two of these ...

  4. Nuclear fission - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fission

    Energy input deforms the nucleus into a fat "cigar" shape, then a "peanut" shape, followed by binary fission as the two lobes exceed the short-range nuclear force attraction distance, and are then pushed apart and away by their electrical charge. In the liquid drop model, the two fission fragments are predicted to be the same size.

  5. Discovery of nuclear fission - Wikipedia

    en.wikipedia.org/wiki/Discovery_of_nuclear_fission

    Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei and often other particles. The fission process often produces gamma rays and releases a very large amount of energy, even by the energetic standards of radioactive decay.

  6. Spontaneous fission - Wikipedia

    en.wikipedia.org/wiki/Spontaneous_fission

    Spontaneous fission (SF) is a form of radioactive decay in which a heavy atomic nucleus splits into two or more lighter nuclei. In contrast to induced fission , there is no inciting particle to trigger the decay; it is a purely probabilistic process.

  7. Fission-fragment rocket - Wikipedia

    en.wikipedia.org/wiki/Fission-fragment_rocket

    The fission-fragment rocket is a rocket engine design that directly harnesses hot nuclear fission products for thrust, as opposed to using a separate fluid as working mass. The design can, in theory, produce very high specific impulse while still being well within the abilities of current technologies.

  8. 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.
