INL Scientists Preparing Power Source For The Next Mars Rover

NASA will be launching a Mars-bound probe in July of 2020 and Martian rover powered by some good, old-fashioned, Idaho-made radioactive decay. Scientists at INL's Space Nuclear Power and Isotope Technologies Division will assemble a plutonium-238 fueled energy unit to power the next rover to traverse the Red Planet. Idaho Matters speaks with the division's director, Dr. Stephen Johnson, about building a better battery for surviving the Martian landscape.
