Manned two crew. Docked with Salyut 5. Conduct of joint experiments with the Salyut-5 orbital research station. Mission was to last for two months; cut short by a gradually worstening illness of Zholobov. Landed 200 km SW Kokchetav. Recovered August 25, 1976 18:33 GMT.
Soyuz 23 was to have docked with the Salyut 5 space station but its long-distance rendezvous system failed. It landed at night (October 16, 1976 17:46 GMT), in a snowstorm, in -20 deg C weather, on the surface of Lake Tengiz. The recovery crews did not find the capsule until the next morning, and were surprised to find the crew alive.
Docked with Salyut 5. A busy, successful mission, accomplishing nearly as much as the earlier Soyuz 21's 50 day mission. Recovered February 25, 1977 9:38 GMT. Landed 37 km NE Arkalyk.
A Soyuz 25 mission to the Salyut 5 space station with the crew of Berzovoi and Lisun was to have followed Soyuz 24. However during the four months it took to prepare the Soyuz, Salyut 5 consumed higher than expected fuel in maintaining the station's orientation. As a result, the fuel reserves were 70 kg below those required for the planned 14 day mission and it was cancelled.
Planned first test manned flight of the TKS large ferry craft. Would have docked with the Almaz OPS 4 military space station. Flight cancelled with the rest of the Almaz program in 1981. The spacecraft was instead flown unmanned to Salyut 6 as Cosmos 1267.
Manned two crew. Carried Anatoli Berezovoi, Valentin Lebedev to Salyut 7 to conduct scientific research and experiments; returned crew of Soyuz T-7 to Earth. Docked with Salyut 7. Recovered September 1, 1982 15:04 GMT.
Retrieved and installed material samples. Tested equipment.
Manned three crew. Docked with Salyut 7.Transported a Soviet-Indian international crew comprising ship's commander Y V Malyshev, flight engineer G M Strekalov (USSR) and cosmonaut-researcher R Sharma (India) to the SALYUT-7 orbital station to conduct scientific and technical studies and experiments. Returned crew of Soyuz T-10 to Earth. Recovered October 2, 1984 10:57 GMT.
Final expedition to Salyut 7 station was cancelled when control was lost.
Transported to the Mir orbital station a Soviet-Afghan crew comprising the cosmonauts V A Lyakhov, V V Polyakov and A A Momand (Afghanistan) to conduct joint research and experiments with the cosmonauts V G Titov and M K Manarov. Returned Manarov, Titov (Soyuz TM-4), Chretien (Soyuz TM-7) to Earth. Initial orbit 195 X 228 km at 51. 57 deg. Maneuvered to a 235 x 259 km orbit, then docked with Mir at 05:41 GMT on 31 August at its 339 x 366 km orbit. Moved from aft to forward port 8 Sept 88. Undocked 03:33 GMT 21 December 1989. Revised software installed as a result of TM-5 abort overloaded computer. Landing planned for 06:48 aborted. Backup program used. Orbital Module retained through retrofire. Recovered December 21, 1988 09:57 GMT. Landed 180 km SE Dzhezkazgan.
