Family: R-7. Country: Russia. Status: Hardware. Other Designations: Vostok. Library of Congress Designation: A-2. Department of Defence Designation: SL-4. ASCC Reporting Name: Sapwood. Article Number: 11A57.

The 11A57 took the large third stage originally developed for the 8K78 interplanetary probe projects and applied it to increasing R-7 low earth orbit performance. It was primarily designed to launch the Zenit-4 reconnaisance satellite, but was also used for the Voskhod manned flights and later for a variety of other Zenit series versions.

1964 Oct 12 - - 07:31 GMT. Launch Site: Baikonur . Launch Complex: LC1.

Voskhod 1 Spacecraft: Voskhod 3KV. Payload: Voskhod 3KV s/n 3. Mass: 5,320 kg.
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." Additional Details: Voskhod 1.

1965 Feb 22 - - 07:41 GMT. Launch Site: Baikonur .

Cosmos 57 Spacecraft: Voskhod 3KD. Payload: Voskhod 3KD s/n 1. Mass: 5,682 kg.
Unsuccessful mission. Voskhod 2 test. Immediately after orbital insertion airlock and spacesuit inflated normally. Then ground controllers sent commands to spacecraft simultaneously instead of sequentially as planned. Signal accidentally set off self destruct mechanism (designed to prevent falling into enemy hands). Blew up past Kamchatka on first orbit. No other test or backup spacecraft built with EVA port. Decision made to go ahead with Voskhod 2 anyway, due to one year leadtime to construct replacement. Planned follow-on Voskhod missions cancelled, including Air Force version, long endurance one man flight, flights by reporters, poets, and scientists.

Cosmos 59 Spacecraft: Zenit-4. Mass: 6,300 kg.
High resolution photo reconnaissance satellite; returned film capsule

1965 Mar 18 - - 07:00 GMT. Launch Site: Baikonur . Launch Complex: LC1.

Voskhod 2 Spacecraft: Voskhod 3KD. Payload: Voskhod 3KD s/n 4. Mass: 5,682 kg.
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. Additional Details: Voskhod 2.
