Radioactive Space Debris Study Cites Hazards to Satellites, Earth
Washington—The growing number of radioactive satellites and nuclear space debris in orbit, most launched by the Soviet Union, poses a threat to other spacecraft and the purity of Earth’s atmosphere, according to a new analysis. “About 50 radioisotope power supplies, nuclear reactors and fuel cores now in orbit pose both near and far-term hazards,” Nicholas L. Johnson, Teledyne Brown Engineering advisory scientist, said.
