Mir Diary - 1989

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
1989 Feb 7 06:45 Progress 39 undocks from Mir
1989 Feb 7 12:49 Progress 39 fires its manoeuvring engine to initiate re-entry and burns up as a result of frictional heating over the Pacific Ocean after some 40 minutes
1989 Feb 10 08:53 Progress 40 launched from the Baikonur Cosmodrome by Soyuz rocket into 187 x 244 kilometre orbit at 51.6 degrees inclination
1989 Feb 12 10:29 Progress 40 docks at the Mir complex Kvant docking port - orbit is 347 x 364 kilometres
1989 Mar 3 01:45 Progress 40 undocks - it then stands-off from Mir while two 'form remembering' structures attached to its hull are unfolded under the observation of the Mir crew
1989 Mar 5 01:08 Progress 40 fires its manoeuvring engine to initiate re-entry and burns up as a result of frictional heating over the Pacific Ocean some 40 minutes later
1989 Mar 16 18:54 Progress 41 launched from the Baikonur Cosmodrome by Soyuz rocket into 187 x 243 kilometre orbit at 51.6 degrees inclination
1989 Mar 18 20:50 Progress 41 docks at the Mir complex Kvant docking port - orbit is 349 x 363 kilometres
1989 Apr 12 The Soviet Union announces that when the current crew leaves Mir on 27 April, the station will remain empty until 1989 August
1989 Apr 21 01:46 Progress 41 undocks - Mir orbit is 372 x 416 kilometres, following nearly three months of occasional thruster firings by visiting spacecraft
1989 Apr 21 Progress 41 fires its manoeuvring engine to lower its orbit as the first part of the re-entry sequence - orbit height is now 213 x 417 kilometres
1989 Apr 21 Progress 41 continues its re-entry manoeuvre but the engine shuts down early due to insufficient propellant being left in the vehicle tanks - Progress 41 is left in an orbit of 128 x 389 kilometres
1989 Apr 25 Mir fires its manoeuvring engine and raises its orbit to 401 x 417 kilometres
1989 Apr 25 12:02 Progress 41 re-enters the Earth atmosphere as the result of air drag and burns up through frictional heating
1989 Apr 26 23:28 Soyuz TM-7 undocks from Mir with Volkov, Krikalyov and Poliakov aboard aboard
1989 Apr 27 02:00 Soyuz TM-7 fires its manoeuvring engine to initiate re-entry
1989 Apr 27 02:57 Soyuz TM-7 lands near latitude 48.5 degrees north, longitude 69.3 degrees east - Krikalyov injures a leg during the rough landing due to high winds
1989 Jul 28 The Soviet Union announces that the next long-stay crew aboard Mir will supervise the attachment of two additional modules to the space station
1989 Aug 23 03:10 Progress M1, an uprated version of Progress, launched from the Baikonur Cosmodrome by Soyuz rocket into 187 x 217 kilometre orbit at 51.6 degrees inclination
1989 Aug 25 05:19 Progress M1 docks at Mir front port - a change from normal routine caused by the logisitics of the upcoming launch of the Kvant 2 module - orbit is 382 x 397 kilometres
1989 Sep 5 21:38 Soyuz TM-8 launched from the Baikonur Cosmodrome by Soyuz rocket into 197 x 200 kilometre orbit at 51.6 degrees inclination with cosmonauts Aleksandr Viktorenko and Aleksandr Serebrov aboard
1989 Sep 7 22:25 Soyuz TM-8 docks with the Mir complex Kvant port - due to a problem with the automatic docking system, the crew takes over manual control at the last moment when Soyuz TM-8 is 4 metres from the docking port - the docking is delayed by five minutes while the crew backs-off to 20 metres and approaches for a second time - Mir orbit is 381 x 395 kilometres
1989 Sep 15 The Soviet Union announces that the next module for Mir will be launched 1989 October 16
1989 Oct 12 The Soviet Union announces a forty day delay in the launch of Mir next module due to the possibility of the presence of faulty microchips in their onboard computers - the planned launch of another module is delayed until spring 1990 for the same reason
1989 Nov 26 13:01 Kvant 2 launched from the Baikonur Cosmodrome by Proton rocket into 215 x 321 kilometre orbit at 51.6 degrees inclination - initially, one solar panel fails to deploy but engineers succeed in releasing it before the docking with Mir
1989 Dec 1 09:02 Progress M1 undocks from Mir
1989 Dec 1 10:32 Progress M1 fires its manoeuvring engine to initiate re-entry and burns up as a result of frictional heating over the Pacific Ocean after some 40 minutes
1989 Dec 2 Kvant 2 approaches Mir but the closing speed is too fast and the automatic docking system aborts the docking while Kvant 2 still has 20 kilometres to run - Kvant 2 passes 2-3 kilometres from Mir - Kvant 2's orbit is 371 x 398 kilometres
1989 Dec 6 12:21 Kvant 2 docks with Mir forward port - orbit is 394 x 398 kilometres
1989 Dec 8 07:19 Using Mir 'Ljappa' manipulator arm, Kvant 2 is deteched from Mir forward port and moved to the upper port on the forward-facing docking hub
1989 Dec 8 08:00 Kvant 2 re-docking is completed
1989 Dec 12 08:22 Soyuz TM-8 undocks with Viktorenko and Serebrov aboard
1989 Dec 12 08:42 Approx time - after Mir has completed a 180 degree rotation, Soyuz TM-7 docks with the forward port
1989 Dec 20 03:30 Progress M-2 launched from the Baikonur Cosmodrome by Soyuz rocket into 187 x 212 kilometre orbit at 51.6 degrees inclination
1989 Dec 22 05:41 Progress M-2 docks at the Mir complex Kvant docking port - orbit is 392 x 395 kilometres
