First spacewalk, with a two man crew of Colonel Pavel Belyayev and Lt. Colonel Aleksey Leonov. During Voskhod 2's second orbit, Leonov stepped from the vehicle and performed mankind's first "walk in space." After 10 min of extravehicular activity, he returned safely to the spacecraft through an inflatable airlock.
This mission was the original raison d'etre of the Voskhod series, with the original name 'Advance'. It almost ended in disaster when Leonov was unable to reenter the airlock due to stiffness of the inflated spacesuit. He had to bleed air from the suit in order to get into the airlock. After Leonov finally managed to get back into the spacecraft cabin, the primary hatch would not seal completely. The environmental control system compensated by flooding the cabin with oxygen, creating a serious fire hazard in a craft only qualified for sea level nitrogen-oxygen gas mixes (Cosmonaut Bondarenko had burned to death in a ground accident in such circumstances, preceding the Apollo 204 disaster by many years). On re-entry the primary retrorockets failed. A manually controlled retrofire was accomplished one orbit later (perhaps with the backup solid rocket retropack on the nose of spacecraft - which did not exist on Vostok). The service module failed to separate completely, leading to wild gyrations of the joined reentry sphere - service module before connecting wires burned through. Vostok 2 finally landed near Perm in the Ural mountains in heavy forest at 59:34 N 55:28 E on March 19, 1965 9:02 GMT. The crew spent the night in the woods, surrounded by wolves, before being located. Recovery crew had to chop down trees to clear a landing zone for helicopter recovery of the crew, who had to ski to the clearing from the spacecraft. Only some days later could the capsule itself be removed.
Proposed high altitude manned Vostok flight for extended scientific studies. Spacecraft would have been allowed to naturally decay to a re-entry after ten days. Purposes of these flights were to be: geophysical and astronomical research; photography of the solar corona; solar x-ray imagery; medical-biological research; detailed study of the effects of weightlessness on the human organism; dosimetry; and engineering tests of ion flow sensors to be used for orientation of later Soyuz spacecraft. All follow-on Vostok missions cancelled in Spring 1964.
Planned Voskhod flight that would include EVA with test of the UPMK 'jet belt'. Cancelled in spring 1966.
The first manned Soyuz flights were an attempt at an 'all up' manned rendezvous, docking, and crew transfer spectacular (eventually accomplished by Soyuz 4 and Soyuz 5). Komarov was the pilot for the Soyuz 1 active spacecraft, which would be launched first. Soyuz 2, with the crew of Bykovsky, Khrunov, and Yeliseyev would launch the following day, with Khrunov and Yeliseyev space-walking to Soyuz 1 and returning to earth with Komarov. Komarov's spacecraft developed serious problems after launch, including the failure of one of the spacecraft's solar panels to deploy. The Soyuz 2 crew were given the order to rendezvous with Soyuz 1 and to try during the planned EVA to unfold the undeployed solar panel. But the launch of Soyuz 2 was cancelled due to heavy rain at the cosmodrome. Low on power and battery reserves, Komarov made an attempt to land the following day. Parachute failure led to the crash of Soyuz 1 and the death of Komarov. After the disaster the Soyuz 2 spacecraft was checked, and the parachute system had the same technical failure. If Soyuz 2 had launched, the docking may have been successful, but then both spacecraft would have crashed on landing, killing four cosmonauts instead of one.
Commander Volynov shuttled the EVA crew of Yeliseyev and Khrunov into earth orbit. A day later Soyuz 4 docked with Soyuz 5. The Soyuz 4 active spacecraft was equipped with a long docking probe, designated 'Shtir'. The Soyuz 5 target spacecraft was equipped with the 'Konus' receptacle. The symbology lead Volynov to joke that he 'was being raped' when the hard docking was accomplished. Khrunov and Yeliseyev transferred to and returned in Soyuz 4, the feat they had hoped to accomplish in the cancelled Soyuz 2 flight almost two years earlier. Officially the flight conducted scientific, technical and medico-biological research, checking and testing of onboard systems and design elements of space craft, docking of piloted space craft and construction of an experimental space station, transfer of cosmonauts from one craft to another in orbit.
Volynov remained behind to live through the most unbelievable re-entry in the history of spaceflight. The service module of the Soyuz failed to separate after retrofire. Once the Soyuz started reaching the tendrils of the atmosphere, the combined spacecraft sought the most aerodynamically stable position - nose forward, with the heavy descent module with its light metal entry hatch at the front, the less dense service module with its flared base to the back. Luckily the struts between the descent and service modules broke off or burned through before the hatch melted through and the descent module righted itself, with the heat shield to the rear, before being consumed. Due to a failure of the soft-landing rockets the landing was harder than usual and Volynov broke his teeth. Recovered January 18, 1969 07:58 GMT.
Tested spacecraft systems and designs, manoeuvring of space craft with respect to each other in orbit, conducted scientific, technical and medico-biological experiments in group flight. Was to have docked with Soyuz 8 and transferred crew while Soyuz 6 took film from nearby. However failure of rendezvous electronics in all three craft due to a new helium pressurization integrity test prior to the mission did not permit successful rendezvous and dockings. Recovered October 17, 1969 9:26 GMT.
Final crews selected for a dual Soyuz mission in Earth orbit to test the Kontakt docking system to be used on the lunar landing LOK and LK spacecraft. The Kontakt-A Soyuz would have been the active spacecraft, simulating the LOK lunar orbiter.
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.
Manned two crew. Docked with Salyut 6. Delivered to the Salyut-6 station the third international 'Intercosmos' crew consisting of V F Bykovsky (USSR) and S Jaehn (German Democratic Republic) to carry out scientific research and experiments.Recovered November 2, 1978 11:05 GMT.
Manned two crew. Transported to the Salyut-6 station the sixth international crew under the Intercosmos programme, comprising V V Gorbatko (USSR) and Pham Tuan (Viet Nam), to conduct scientific research and experiments. Returned crew of Soyuz 35 to Earth. Recovered October 11, 1980 9:50 GMT.
