Mir Diary - 1990

A Chronology of mission events in orbit and on the ground. Mir existed for fifteen years growing from the original 20 tonne core module to a massive 130+ tonnes.

Date Time (UTC) Event

1990 Feb 21 03:56 Soyuz TM-9 undocks with Solovyov and Balandin aboard aboard

1990 Jun 6 11:30 Planned docking time for Kristall with Mir - the manoeuvre is called off when an attitude control thruster aboard Kristall fails
