NASA is now planning to build a nuclear powered spacecraft/rovers. NASA says that nuclear spacecrafts will come with more onboard power than
scientists know what to do with. Also NASA says that nuclear powered crafts can go farther and faster. NASA is now on to some projects with nuclear
powered carfts. One is the unmanned lander that will go to Mars in 2009. Another is a plan for nuclear-electric propulsion system for the robotic tour
of Jupitar's icy moons in 2015.
Looking farther into the future, NASA, with the help of the Energy Department, is hard at work on the nuclear power system needed for the Jupiter
Icy Moons Orbiterís planned 10- to 15-year mission to explore the largest planet in the solar system and three of its moons. The Energy Department,
working with industry, is designing a space-qualified nuclear fission reactor capable of generating 100 kilowatts of power -- about 1,000 times more
than most solar-powered space probes have available today.
