Sergei Krikalev was in space when the Soviet Union collapsed. Unable to come home, he wound up spending two times longer than originally planned in orbit. They simply refused to bring him back.
While tanks were rolling through Moscow’s Red Square, people built barricades on bridges, Mikhail Gorbachev and the Soviet Union went the way of history, Sergei Krikalev was in space. 350 km away from Earth, the Mir space station was his temporary home.
He was nicknamed “the last citizen of the USSR.” When the Soviet Union broke apart into 15 separate states in 1991, Krikalev was told that he could not return home because the country that had promised to bring him back home no longer existed.
