Nuclear space power and propulsion systems

What is NASA's Space Nuclear Propulsion project?

NASA’s space nuclear propulsion project is led by the agency’s Space Technology Mission Directorate and funded through its Technology Demonstration Missions program based at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Why are nuclear propulsion systems important?

Nuclear propulsion systems can also provide much higher power for onboard instruments and communication systems, which can be especially beneficial as the spacecraft travels farther from the Sun where the ability to harness solar power becomes impractical.

What is space nuclear propulsion (SNP)?

Space Nuclear Propulsion (SNP) is one technology that can provide high thrust and double the propellant efficiency of chemical rockets, making it a viable option for crewed missions to Mars.

Will NASA develop nuclear thermal propulsion technology in 2027?

“NASA will work with our long-term partner, DARPA, to develop and demonstrate advanced nuclear thermal propulsion technology as soon as 2027. With the help of this new technology, astronauts could journey to and from deep space faster than ever – a major capability to prepare for crewed missions to Mars,” said NASA Administrator Bill Nelson.

Which DOE facilities support NASA's Space Nuclear Propulsion project?

The project, also at Marshall, collaborates with DOE to advance the key technologies needed for future human missions to Mars. DOE facilities supporting NASA’s space nuclear propulsion project include Idaho National Laboratory, Oak Ridge National Laboratory, and Los Alamos National Laboratory.

How does space nuclear propulsion work?

Space nuclear propulsion draws energy from atomic fission reactions instead of traditional chemical reactions, thus providing comparatively unlimited energy and opening the door for robust and enduring access throughout the solar system.
