Their spectacular achievements included the first man and woman in space. They seemed unstoppable – until a string of misfortunes struck. The deaths of Sergei Korolev, the godfather of the program, and icon Yuri Gagarin, were followed by mechanical setbacks. America ultimately claimed victory. But it didn't end there. In the 1970s, the Soviets recalibrated their space program, coming to dominate modern space exploration.
