U.S. Department of Energy

US

The U.S. Department of Energy (DOE) plays a crucial role in the space industry by providing essential technologies and research support for space exploration and national security missions. It acts as a key partner with NASA and other agencies in developing space-based power systems, including radioisotope thermoelectric generators (RTGs) and fission surface power systems, which provide electricity and heat in the harsh conditions of space. The DOE also contributes to space science research, particularly in understanding dark matter and dark energy, and supports the development of quantum technologies for space applications. Keywords associated with the DOE's space involvement include radioisotope power systems, space nuclear power, quantum technology, NASA partnerships, and space exploration.
