What is Plutonium-238? National Aeronautics and Space Administration What is plutonium? â¢ Plutonium is a metallic chemical element with a silvery-white color. The plutonium used on NASA spacecraft is transformed in a laboratory into a silvery-black ceramic material called plutonium dioxide. Plutonium-238 is a special material that emits steady heat due to its natural radioactive decay.
