TKS VA capsule
TKS VA capsule - The landing capsule of the three crew military TKS transport/resupply spacecraft for the Almaz space station. Called ‘our Apollo’ by cosmonaut Leonov. After separation of the capsule from the Almaz the retrorocket assembly at top deorbited the capsule. TKS capsules (VA is the Russian acronym) flew 13 times between 1976 and 1983, ten times in capsule tests, three times as part of complete TKS spacecraft which docked with Salyut space stations. They were never flown manned.

Other Designations: Merkur; VA Vozvrashchaemiy Apparat. Article Number: 11F74. Manufacturer's Designation: TKS VA. Class: Manned. Type: Spacecraft. Nation: USSR. Manufacturer: OKB-52.

TKS VA capsules were launched in pairs by Proton boosters in 1976 to 1979 in a seemingly exhaustive series of flight tests to prove the design. They also flew as part of the complete TKS ferry spacecraft Cosmos 929, 1267, and 1443 in 1977-1983. Despite this, they were never flown manned.

TKS VA Chronology


15 December 1976 Cosmos 881 Program: Almaz. Launch Site: Baikonur . Launch Vehicle: Proton 8K82K. Mass: 4,250 kg. Perigee: 201 km. Apogee: 241 km. Inclination: 51.6 deg. Duration: 0.06 days.

Double reentry test of TKS-VA capsule of TKS orbital shuttle. Spacecraft each weighed 9,090 kg. One was placed into a lower 189 X 213 km orbit, the other at the higher orbit indicated. After one orbit, both recovered at 44 deg N, 73 deg E, on December 15, 1976 3:00 GMT.


04 August 1977 TKS VA s/n 009P/P Program: Almaz. Launch Site: Baikonur . Launch Vehicle: Proton 8K82K. FAILURE: Failure.
30 March 1978 Cosmos 998 Program: Almaz. Launch Site: Baikonur . Launch Vehicle: Proton 8K82K. Mass: 4,250 kg. Perigee: 200 km. Apogee: 230 km. Inclination: 51.6 deg.

Dual reentry test of two TKS-VA capsules. Recovered March 30, 1978 after one orbit.


20 April 1979 TKS VA s/n 103 Program: Almaz. Launch Site: Baikonur . Launch Vehicle: Proton 8K82K. FAILURE: Engines ignited but immediately shut down on launch pad. Mass: 4,250 kg.
23 May 1979 Cosmos 1100 Program: Almaz. Launch Site: Baikonur . Launch Vehicle: Proton 8K82K. Mass: 4,250 kg. Perigee: 193 km. Apogee: 222 km. Inclination: 51.6 deg. Duration: 0.06 days.

Dual test of TKS-VA manned capsule. One vehicle reentered and landed after two orbits, the other after one orbit. The top capsule was to have been manned, but the inability to demonstrate two consecutive failure free launches of the Proton/TKS-VA combination made that impossible. This launch successfully demonstrated the reusability of the TKS-VA capusle; the same pair had flown as Cosmos 997/998 on 30 March 1978.

The TKS crew instruments were assembled from the same building blocks as those used in the Soyuz series of spacecraft. The standard clock, used since Vostok, is in the top middle of the panel. The large central panel was used to call up sequences of automated spacecraft procedures.

TKS capsule hatchTKS capsule hatch - The crew of the TKS went from the descent capsule to the main spacecraft cabin through this hatch in the heat shield of the capsule. The central crew couch folded up to give access to the hatch. A similar arrangement was to be used in Gemini B for the USAF MOL (Manned Orbiting Laboratory).
