NASA Researchers Studying Advanced Nuclear Rocket Technologies

Artist's Depiction of Nuclear Thermal Rocket

(NASA.gov – 01.09.13) A nuclear rocket engine uses a nuclear reactor to heat hydrogen to very high temperatures, which expands through a nozzle to generate thrust. Nuclear rocket engines generate higher thrust and are more than twice as efficient as conventional chemical rocket engines. Advanced propulsion researchers at NASA are a step closer to solving the challenge of safely sending human explorers to Mars and
