Stanislav Petrov, a former Soviet military officer, poses at his home in 2015 near Moscow. In 1983, he was on duty when the Soviet Union's early warning satellite indicated the U.S. had fired nuclear weapons at his country. He suspected, correctly, it was a false alarm and did not immediately send the report up the chain of command. Petrov died at age 77. Pavel Golovkin/AP
