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.

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
