In the night of 9 October to 10 October 1991 ascended the commandant of the cadre Anatoli Arzebarskij, the board engineer of the guest crew Toktar Aubakirov and the Austrian scientific cosmonaut Franz Viehboeck from the space station MIR into the space transporter Soyuz TM-12, which had allready docked on 20 May 1991 at 6:15 p.m. CET with an English-Soviet crew at the space station MIR. The docking off of Soyuz TM-12 from the MIR resulted on 10 October 1991 at 01:52 a.m. CET.
The landing of Soyuz TM-12 was on 10 October 1991 at 05:12 a.m. CET (08:12 a.m. local time) 58 km eastern of Arkalyk (Kazakhstan).
The flight routing center had radio and TV-contact with the crews on board of MIR and Soyuz TM-12 from docking off to the landing of Soyuz TM-12 as follows:
10:45 p.m. |
Closing of the hatch |
10:45 p.m. – 11:40 p.m. |
Check of the impermeability of the docking lug |
11:40 p.m. – 00:40 a.m. |

Entry of the landing machine into the earth atmosphere |
04:50 a.m. |
Start of the controlled descent |
04:50 a.m. – 04:55 a.m. |
