NUCLEAR IN OUTER SPACE 🚀 Did you know many NASA - National Aeronautics and Space Administration missions use nuclear power in space? For decades, radioisotope power systems have supported spacecraft traveling to the farthest reaches of our Solar System. Now the U.S. Department of Energy is working with NASA to develop new technologies to propel our exploration of outer space further and faster. Nuclear thermal propulsion rockets could dramatically cut down the time it would take a crew to trave
