Yet, with this chemical quickly becoming scarce, it may be the last, scientists worry. Curiosity is scheduled to launch Saturday (Nov. 26) on a ground- breaking mission to the Red Planet. When the car-size rover reaches the surface of Mars next August, it will be powered with a special type of the element, called plutonium-238. For 50 years, NASA has used plutonium-238 as the fuel source for unmanned spacecraft to study planets and other objects in the outer solar system, but stockpiles of this material are running dry. Without additional stores of this fuel, the agency's ability to conduct future planetary science is in jeopardy. That is something the United States simply cannot afford, scientists say: http://tinyurl.com/crcpbbu Terry W.
