An alternative technology to the chemically propelled rockets the agency develops now is called nuclear thermal propulsion, which uses nuclear fission and could one day power a rocket that makes the trip in just half the time.Nuclear fission involves harvesting the incredible amount of energy released when an atom is split by...

NASA Space Technology An artist's impression of Europa Clipper performing a flyby of Europa as it orbits Jupiter(Image credit: NASA/JPL-Caltech)NASA has successfully launched the Europa Clipper, the agency's biggest-ever interplanetary spacecraft, into space and it's now headed for Jupiter's frozen moon Europa."Congratulations to our Europa Clipper team for beginning the first journey to an ocean world beyond Earth," NASA Administrator Bill Nelson said in a statement.The craft took off Oct. 14 on top of a SpaceX Falcon Heavy rocket from NASA's Kennedy Space Center in Florida. It was originally slated to launch Oct. 10, but the mission was pushed back because of Hurricane Miltonwhich smashed into Florida Oct. 9.When the Europa Clipper arrives in 2030, the orbiter will study the frozen moon's hidden ocean, which is locked beneath an icy shell, to determine how...
