Two days later, on March 15 this year, Soyuz T 15 docked with the "Peace" space station that just entered orbit for the first time. Two astronauts checked the sealing of the docking part of the spacecraft and the space station and entered the "Peace" space station. They debugged more than 0/000 pieces of instruments and equipment on the station and unloaded the materials sent by the cargo ship "Progress 26" to prepare for the "Peace" space station to start receiving astronauts.
Fifty days later, on May 5 this year, Soyuz T 15 was detached from the space station Heping-Progress 26, then sailed to Salute 7, with a journey of more than 3,000 kilometers, and docked with Salute 7- Cosmos 65438 on May 6. Two astronauts entered the consortium to work, carried out many scientific investigations and experimental activities, walked out of the cabin many times and assembled large parts.
On June 27th, 52 days later, Soyuz T 15 spacecraft broke away from Salute 7 and docked with Mir Space Station again. The two astronauts stopped working until July 16, and then left the "Peace" space station to return to the ground.
People call Soyuz T 15, which travels between two space stations, "the first bus in space".
