Docking with Salyut 7
Docking portAft

Soyuz T-9 (Russian: Союз Т-9, Union T-9) was the 4th expedition to Salyut 7 following the failed docking of Soyuz T-8. It returned lab experiments to Earth. The next mission, Soyuz 7K-ST No.16L (Soyuz 10a), had exploded and thus failed to launch.

Soyuz T-9 achieved successful docking with the station, although the mission was bracketed by the failed attempt of Soyuz T-8 and the launch pad abort of Soyuz T-10 which would follow immediately.[1]
