Stranded in space: the story of Sergei Krikalev, the last Soviet cosmonaut

Soviet cosmonaut Sergei Krikalev (born August 27, 1958) was in space when the Soviet Union fell apart in 1991. He was stranded on board the Mir Space Station during the dissolution of the USSR. As the country that had sent him into space no longer existed, his return was delayed until further notice. He stayed in orbit for 311 consecutive days, twice as long as the original duration of the mission. He eventually returned back to earth – to a very different nation.
