Joint flight with Vostok 3. Acquisition of experimental data on the possibility of establishing a direct link between two space ships; coordination of astronauts' operations; study of the effects of identical spaceflight conditions on the human organism. Popovich had problems with his life support system, resulting in the cabin temperature dropping to 10 degrees Centigrade and the humidity to 35%. The cosmonaut still managed to conduct experiments, including taking colour motion pictures of the terminator between night and day and the cabin interior.
Despite the conditions, Popovich felt able to go for the full four days scheduled. But before the mission, Popovich had been briefed to tell ground control that he was 'observing thunderstorms' if he felt the motion sickness that had plagued Titov and needed to return on the next opportunity. Unfortunately he actually did report seeing thunderstorms over the Gulf of Mexico, and ground control took this as a request for an early return. He was ordered down a day early, landing within a few mintutes of Nikolayev. Only on the ground was it discovered that he was willing to go the full duration, and that ground control had thought he had given the code. Recovered August 15, 1962 6:59 GMT. Landed 48:09 N 71:51 E.
Korolev proposed further manned Vostok flights after Vostok 6. The first was to be a high altitude flight into the lower Van Allen radiation belt for radiological-biological studies. Spacecraft would have been allowed to naturally decay to a re-entry after ten days. A training group for these flights was assigned on 17 September 1963: Belyayev, Gorbatko, Khrunov, Komarov, Leonov, Shonin, Volynov, and Zaikin. By 25 January 1964 this had changed to Belyayev, Beregovoi, Khrunov, Komarov, Leonov, and Volynov. All follow-on Vostok missions were cancelled in spring 1964 when the decision was made to proceed with conversion of Vostok to the multi-crew Voskhod configuration.
The U.S.S.R. launched the world's first multi-manned spacecraft, Voskhod I, the first to carry a scientist and a physician into space. The crew were Col. Vladimir Komarov, pilot; Konstantin Feoktistov, scientist; and Boris Yegorov, physician. Potentially dangerous modification of Vostok to upstage American Gemini flights; no spacesuits, ejection seats, or escape tower. One concession was backup solid retrorocket package mounted on nose of spacecraft. Seats mounted perpendicular to Vostok ejection seat position, so crew had to crane their necks to read instruments, still mounted in their original orientation. Tested the new multi-seat space ship; investigated the in-flight work potential and co-operation of a group of cosmonauts consisting of specialists in different branches of science and technology; conducted scientific physico-technical and medico-biological research. The mission featured television pictures of the crew from space.
Land recovery made possible by rocket package suspended above capsule in parachute lines, which ignited just prior to impact in order to cushion landing. The trio landed after 16 orbits of the earth, 24 hours and 17 min after they had left, on October 13, 1964 7:47 GMT.
Coming before the two-man Gemini flights, Voskhod 1 had a significant worldwide impact. In the United States, the "space race" was again running under the green flag. NASA Administrator James E. Webb, commenting on the spectacular, called it a "significant space accomplishment." It was, he said, "a clear indication that the Russians are continuing a large space program for the achievement of national power and prestige."
Space disaster that put back Soviet lunar program 18 months. Soyuz 1 as active spacecraft was launched first. Soyuz 2, with a 3 man crew would launch the following day, with 2 cosmonauts spacewalking to Soyuz 1. However immediately after orbital insertion Komarov's problems started. One of the solar panels failed to deploy, staying wrapped around the service module. Although only receiving half of the planned solar power, an attempt was made to manoeuvre the spacecraft. This failed because of interference of the reaction control system exhaust with the ion flow sensors that were one of the Soyuz' main methods of orientation. The decision was then made to bring Komarov back. Re-entry was successful and the drag chute deployed. However due to a failure of a pressure sensor, the main parachute would not deploy. Komarov released the reserve chute, but it became tangled with the drag chute. The descent module crashed into a field near Orenburg at 7 am.
