> Under the agreement with DOE, Zeno will have access to a large supply of strontium-90, a radioisotope created as a byproduct in nuclear fission reactors. The company will use the material to build radioisotope power sources, or RPS systems. These are compact devices that convert heat from isotopes into electricity. NASA for decades has used RPS systems for deep-space missions, but these systems are fueled by plutonium-238, an isotope that is in limited supply. Zeno designed an RPS system for small satellites fueled by strontium-90.
