Both Russia and the U.S. have detonated nuclear warheads in space. In the 1960s, little was known about how the relatively new weapons of mass destruction would act in the Earth’s atmosphere. Both countries experimented to find out. The Soviet tests were called Project K and took place from 1961 to 1962. The U.S. conducted 11 tests of its own, and the largest, and first…
