Expedition 5 (1981) and The End

1981 saw the final round of Salyut 6 visits. Towards the end, the space station was docked with another, similar sized, 20 tonne spacecraft - Cosmos 1267. It arrived and docked just over a month after the last cosmonauts departed, having been in orbit for two months in its own right. It was one of a series of large, manoeuvrable spacecraft, some of which (Cosmos 1267 included) were equipped with a crew cabin capable of returning to Earth. None, however, carried cosmonauts.

These were the 'TKS' spacraft from the Chelomei Design Bureau that had originally been intended to operate with the 'Almaz' type space stations. When the Almaz programme was cancelled, some of the TKS vehicles were re-routed in the the Korolyov Bureaus's DOS programme.

Cosmos 1267 remained with Salyut 6 until the end, just over a year after the departure of the last crew. Mid-1982, the combination spacecraft was guided to a destructive re-entry over the southern Pacific Ocean to avoid the possibility of it re-entering naturally and hitting an inhabited part of the Earth.

1981 Mar 30 11:40 Soyuz 39 lands - 170 kilometres south-east of Dzhezhkazgan
1981 Apr 25 02:00 Cosmos 1267, a 20 tonne TKS spacecraft carrying cargo, launched from the Baikonur Cosmodrome by Proton rocket into 192 x 260 kilometre orbit - it spends two months in independent flight before docking with Salyut 6 - 1981 Jun 19
1981 May 12 Kovalyonok and Savinikh dismantle the docking probe of Soyuz T-4 as an experiment to demonstrate the ability to change it to a passive type docking receptor

1981 May 26 09:20 Approx time - Soyuz T-4 undocks with Kovalyonok and Savinikh aboard
1981 May 26 12:37 Soyuz T-4 lands - 125 kilometres east of Dzhezhkazgan
1981 Jun 19 06:52 Cosmos 1267 docks at the forward port of Salyut 6 after nearly two months of independent flight - orbit is 333 x 361 kilometres
1982 Jul 28 Salyut 6/Cosmos 1267 orbit is 318 x 324 kilometres - a firing of Salyut 6 engine reduces the height
1982 Jul 29 A firing of Cosmos 1267 engine results in the space complex re-entering the Earth atmosphere - both Salyut 6 and Cosmos 1267 are destroyed by frictional heating
