Soyuz 7K-T
The second generation of the Soyuz spacecraft, the ''Soyuz 7K-T'', comprised Soyuz 12 through Soyuz 40 (1973-1981). In the wake of the Soyuz 11 tragedy, the spacecraft was redesigned to accommodate two cosmonauts who would wear pressure suits at all times during launch, docking, undocking, and reentry. The place of the third cosmonaut was taken by extra life-support systems. Finally, the 7K-T, being intended purely as a space station ferry, had no solar panels, instead sporting two large whip antennas in their place. As a result, it relied on batteries which only provided enough power for two days of standalone flight. The idea was that the Soyuz would recharge while docked with a Salyut space station, but in the event of a docking or other mission failure (which ended up happening on several occasions), the crew was forced to power off everything except communications and life support systems until they could reenter. Two test flights of the 7K-T were conducted prior to comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sokol Space Suit
The Sokol space suit, also known as the Sokol IVA suit or simply the Sokol (russian: Cокол, , Falcon), is a type of Soviet/Russian space suit, worn by all who fly on the Soyuz spacecraft. It was introduced in 1973 and is still used . The Sokol is described by its makers as a ''rescue suit'' and it is not capable of being used outside the spacecraft in a spacewalk or extravehicular activity. Instead, its purpose is to keep the wearer alive in the event of an accidental depressurisation of the spacecraft. In this respect, it is similar to the ACES suit that was worn aboard NASA's Space Shuttle during launch and landing. Description The current version of the suit is the Sokol-KV2, manufactured by NPP Zvezda (НПП Звезда). It consists of an inner pressure layer of rubberised polycaprolactam and an outer layer of white nylon canvas. Boots are integrated with the suit but gloves are removable and attach by means of blue anodised aluminium wrist couplings. The polycarbonat ...

Soyuz 25
Soyuz 25 (russian: Союз 25, ''Union 25'') was an October, 1977, Soviet crewed space flight, the first to the new Salyut 6 space station, which had been launched 10 days earlier. However, the mission was aborted when cosmonauts Vladimir Kovalyonok and Valery Ryumin failed to engage the docking latches of the station despite five attempts. Lacking sufficient fuel to attempt a dock at the other end of the station and with battery power for only two days, they returned to Earth.The mission report is available here: http://www.spacefacts.de/mission/english/soyuz-25.htm The failure led to a new rule whereby every crew had to have at least one person aboard who had previously flown in space.

Soyuz 23
Soyuz 23 (russian: Союз 23, ''Union 23'') was an October, 1976, Soviet crewed space flight, the second to the Salyut 5 space station. Cosmonauts Vyacheslav Zudov and Valery Rozhdestvensky arrived at the station, but an equipment malfunction did not allow docking and the mission had to be aborted. The crew returned to Earth, but landed on partially frozen Lake Tengiz, the first crewed splashdown in the Soviet space program. While there was no concern about any immediate threat to the crew, the capsule sank under the surface of the frozen lake, and recovery took nine hours owing to fog and other adverse conditions. The landing marked the only example of an unintentional splashdown of a crewed spacecraft to date. Crew Backup crew Reserve crew Mission highlights Soyuz 23 was launched 14 October 1976 with an estimated 73- to 85-day mission planned aboard the orbiting Salyut 5 space station.

Soyuz 21
Soyuz 21 (russian: Союз 21, ''Union 21'') was a 1976 Soviet crewed mission to the Salyut 5 space station, the first of three flights to the station. The mission's objectives were mainly military in scope, but included other scientific work. The mission ended abruptly with cosmonauts Boris Volynov and Vitaly Zholobov returning to Earth after 49 days in orbit. The precise reason for the early end of the mission was the subject of much speculation, but was reported to be an emergency evacuation after the Salyut atmosphere developed an acrid odor.

Soyuz 15
Soyuz 15 (russian: Союз 15, ''Union 15'') was an August, 1974, crewed space flight which was to have been the second mission to the Soviet Union's Salyut 3 space station with presumably military objectives. Launched 26 August 1974, the Soyuz spacecraft arrived at the station, but cosmonauts Gennady Sarafanov, and Lev Dyomin were unable to dock because the electronics in the Igla docking system malfunctioned. Without sufficient fuel for prolonged attempts at manual docking, the mission had to be abandoned. The cosmonauts powered down all nonessential systems in the Soyuz and waited until the next day for reentry. The crew landed 28 August 1974. Analysis of the launch window was cited by observers for concluding a flight of 19 to 29 days had been planned. In the event of the failure, official TASS statements merely claimed that the mission was intended to practice docking maneuvers with the Salyut 3 station. They also said that a new automatic docking system was tested wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soyuz 14
Soyuz 14 (russian: Союз 14, ''Union 14'') was a July, 1974, crewed spaceflight to the Salyut 3 space station. ''Soyuz 14'' is also the name given to the Soyuz spacecraft which was used to bring the cosmonauts to and from the station. The mission was part of the Soviet Union's Almaz program to evaluate the military applications of crew spaceflight. The mission's crew members were cosmonauts Pavel Popovich and Yuri Artyukhin. At the time, the military nature of this mission and the station itself were not acknowledged by Soviet authorities. The flight was the first successful mission to a space station by the Soviets. The mission proved to be the only one for Salyut 3 as Soyuz 15 failed to dock with the station in August 1974 and the station was de-orbited in January 1975. With the American Skylab missions now complete, the flight marked the start of the monopoly of crewed space activities by the Soviets until the 1981 launch of STS 1, the first Space Shuttle flight, save ...

Almaz
The Almaz (russian: Алмаз, lit=Diamond) program was a highly secret Soviet military space station program, begun in the early 1960s. Three crewed military reconnaissance stations were launched between 1973 and 1976: Salyut 2, Salyut 3 and Salyut 5. To cover the military nature of the program the three launched Almaz stations were designated as civilian Salyut space stations. Salyut 2 failed shortly after achieving orbit, but Salyut 3 and Salyut 5 both conducted successful crewed testing. Following Salyut 5, the Soviet Ministry of Defense judged in 1978 that the time and resources consumed by station maintenance outweighed the benefits relative to automatic reconnaissance satellites. The space stations' cores were known internally as OPS (russian: ОПС, GRAU index 11F71 and 11F71B), from "Orbital Piloted Station" (russian: Орбитальная Пилотируемая Станция). As part of the Almaz program, the Soviets developed several spacecraft for support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
