Late in the spring of 1991, Soviet cosmonauts Sergei Krikalev and Anatoli Artsebarski, along with Britain's first astronaut, Helen Sharman, blasted off into space towards Mir, the Soviet space station. Sergei Krikalev’s and Anatoli Artsebarski’s mission was to relieve the existing crew of the space station, while Helen Sharman was onboard as part of the British Juno program to conduct experiments on life sciences. Sharman returned back to earth together with the crew of the previous mission eight days later, leaving Krikalev and Artsebarski circling around the earth conducting repairs on the ailing space station. Five months later, Anatoli Artsebarski went home too, but Krikalev didn’t mind—he was trained for long-duration flights. Two years earlier, Krikalev had spent 152 days aboard Mir. He did not know then, that this mission was going to be his longest.
