- Antiproton-catalyzed micro-fusion and fusion propulsion - This page by the Advanced Propulsion Technology Group at NASA JPL deals with inertial-confinement antiproton-catalyzed micro-fission/fusion nuclear (ICAN) propulsion concept under development at Pennsylvania State University (PSU)
- Gas core nuclear rockets - Short of using antimatter, the highest reactor core temperature in a nuclear rocket can be achieved by using gaseous fissionable material. In the gas-core rocket, radiant energy is transferred from a high-temperature fissioning plasma to a hydrogen propellant. Advanced Propulsion Technology Group at NASA JPL.
- High-Temperature Nuclear Reactors for Space Applications - Institute of Physics and Power Engineering (IPPE) at the State Research Center of Russian Federation is one of the primary developers of compact, efficient reactors for space nuclear power systems which use direct conversion of nuclear heat into electrical energy. Between 1970-1984 seven power systems with reactors of this type were tested on the ground at the special IPPE test site. "TOPAZ" units were tested twice in space as an electric power source for the "COSMOS" satellites. Thermionic fuel elements (TFE's) for "TOPAZ" reactors were designed, fabricated, and in-pile tested in the IPPE.

- Nuclear Propulsion Introduction - This website by the Advanced Propulsion Technology Group at NASA JPL contains a detailed introduction to various forms of nuclear propulsion under study at NASA and other research agencies.
- ORION Nuclear Pulse Vehicle - This site contains some drawings and model photographs that illustrate several design concepts for the Orion nuclear pulse powered space vehicle proposed inthe late 1950's.
- Orion nuclear spaceship - A description of the concept for starship propulsion that would utilize a regular series of small nuclear explosions.
- Particle bed nuclear rockets - This website by the Advanced Propulsion Technology Group at NASA JPL contains a detailed introduction to the Particle bed nuclear rocket. In the particle-bed (fluidized-bed, dust-bed, or rotating-bed) reactor, the nuclear fuel is in the form of a particulate bed through which the working fluid is pumped.
- Radioisotope "poodle" thruster - This website by the Advanced Propulsion Technology Group at NASA JPL contains a detailed introduction to the radioisotope "poodle" thruster. The "Poodle" thruster concept is derived from radioisotope thermoelectric generator (RTG) technology. Basically, the thermoelectric converters from the RTG are removed, and energy from the RTG nuclear fuel capsules is used to heat a propellant "working fluid," such as hydrogen, water, helium, etc., to temperatures of 1500 to 2000 degrees C and then expand the hot gas through a nozzle.
- Solid core nuclear rockets - This website by the Advanced Propulsion Technology Group at NASA JPL contains a detailed introduction to solid core nuclear rockets.
