First flight between space stations

Mir EO-1 was the first expedition to the new Soviet Mir space station. Its crew, Leonid Kizim and Vladimir Solovyov, launched from Earth on 13 March 1986, docking with Mir two days later. They remained on Mir for six weeks, during which time they changed the station’s orbit to match that of the Salyut 7 space station. On 5 May 1986 the crew undocked their Soyuz spacecraft from Mir and docked with Salyut 7 after a 29-hour long flight. Salyut 7 was unoperational at the time and deeply frozen and the crew had to bring the station back to life. On 25 June, the crew undocked from Salyut 7 and returned to Mir, bringing equipment from the old station to the new.
