Soyuz T-12 (also known as Salyut 7 EP-4) was the seventh crewed spaceflight to the Soviet space station Salyut 7. The name "Soyuz T-12" is also the name of the spacecraft used to launch and land the mission's three-person crew. The mission occurred in July 1984, during the long-duration expedition Salyut 7 EO-3. During the mission, crew member Svetlana Savitskaya became the first woman to ever perform a spacewalk, and the potential Buran space shuttle pilot, Igor Volk, was given spaceflight experience. Unlike many Soyuz visiting missions, the Soyuz lifeboats were not swapped, and the crew returned to Earth in the same spacecraft in which they launched.

Background

Igor Volk was a test pilot, and was planned to be the commander of the first Buran spaceflight. The rule introduced following the Soyuz 25 failure, insisted that all Soviet spaceflight must have at least one crew member who has been to space before. As a result, it was decided that Volk should have spaceflight experience, and he was originally scheduled to visit Salyut 7 in 1983. [2] But following the failure of Soyuz T-8 to dock to Salyut 7, in April 1983, the Soyuz launch schedule was disrupted, and Volk's original crew members, Kizim and Solovyov, were rescheduled elsewhere. [2] They later became long-duration crew members of Salyut 7 EO-3, and Volk was scheduled fly in the passenger seat of a visiting mission Soyuz T-12 to the EO-3 crew, but the other members of the T-12 mission were not yet decided upon. [2]

In November 1983, NASA announced that during STS-41-G, Kathryn D. Sullivan would become the first woman to perform a spacewalk. [2] The NPO Energia chief decided that the Soviets would get there first, and assembled the Soyuz T-12 crew within a month of NASA's announcement, which included Volk as previously planned.

The back-up crew lists became available to Western space analysts in 1988, and they noted that the back-up crew contained a woman, but did not contain another LII test pilot. Judging from this, it appeared that, as reasons to have the Soyuz T-12 mission, achieving the first female spacewalk was more important than gaining experience for a potential Buran crew member. [2]

At the time of the mission the Buran program was still a state secret. The appearance of Volk as a crew member caused some, including the British Interplanetary Society magazine Spaceflight , to ask why a test pilot was occupying a Soyuz seat usually reserved for researchers or foreign cosmonauts.

Mission highlights

Soyuz T-12 was the 7th expedition to Salyut 7.

Volk was a glimpse of things which might have been: he was a Buran programme program pilot being flown in space to prove he would be able to pilot Buran back to Earth after an extended stay in space.

The crew of Soyuz T-12 (callsign Pamir), the second Visiting Expedition to visit the Mayaks, included veteran cosmonaut Vladimir Dzhanibekov, Buran shuttle program cosmonaut Igor Volk, and Svetlana Savitskaya. On July 25 Dzhanibekov and Savitskaya performed a 3 hr, 30 min EVA (Savitskaya became the first woman ever to perform EVA), during which they tested the URI multipurpose tool. They cut, welded, soldered, and coated metal samples. During the Pamirs’ stay, the six cosmonauts aboard Salyut 7 also conducted Rezonans tests and collected station air samples.

Extravehicular activity Activity done by an astronaut or cosmonaut outside a spacecraft

Extravehicular activity (EVA) is any activity done by an astronaut outside a spacecraft beyond the Earth's appreciable atmosphere. Normally, the term applies to what has been termed a spacewalk outside a craft that is orbiting Earth. However EVA also applies to lunar surface exploration, as performed by six pairs of American astronauts in the Apollo program from 1969 to 1972. A Stand-up EVA (SEVA) is when an astronaut does not fully leave a spacecraft, but is completely reliant on the space suit for environmental support. Its name derives from the astronaut "standing up" in the open hatch, usually to record or assist a spacewalking astronaut. The Soviet Union/Russia, the United States, Canada, the European Space Agency and China have all conducted EVAs.

<i>Mir</i> Soviet/Russian space station that operated in low Earth orbit from 1986 to 2001

Mir was a space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia. Mir was the first modular space station and was assembled in orbit from 1986 to 1996. It had a greater mass than any previous spacecraft. At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station (ISS) after Mir's orbit decayed. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology, and spacecraft systems with a goal of developing technologies required for permanent occupation of space.

Svetlana Savitskaya Soviet cosmonaut

Svetlana Yevgenyevna Savitskaya is a Russian former aviator and Soviet cosmonaut who flew aboard Soyuz T-7 in 1982, becoming the second woman in space. On her 1984 Soyuz T-12 mission she became the first woman to fly to space twice, and the first woman to perform a spacewalk.

Salyut 7 Space station launched on 19 April 1982

Salyut 7 was a space station in low Earth orbit from April 1982 to February 1991. It was first crewed in May 1982 with two crew via Soyuz T-5, and last visited in June 1986, by Soyuz T-15. Various crew and modules were used over its lifetime, including 12 crewed and 15 uncrewed launches in total. Supporting spacecraft included the Soyuz T, Progress, and TKS spacecraft.

Anatoly Yakovlevich Solovyev is a retired Russian and Soviet cosmonaut and pilot. Solovyev was born on January 16, 1948, in Riga, Latvia. Solovyev holds the world record on the number of spacewalks performed (16), and accumulated time spent spacewalking.

Gennady Strekalov Soviet-Russian engineer and cosmonaut

Gennady Mikhailovich Strekalov was an engineer, cosmonaut, and administrator at Russian aerospace firm RSC Energia. He flew into space five times and lived aboard the Salyut 6, Salyut 7, and Mir space stations, spending over 268 days in space. The catastrophic explosion of a Soyuz rocket in 1983 led to him being one of only four people to use a launch escape system. He was decorated twice as Hero of the Soviet Union and received the Ashoka Chakra from India.

Soyuz 39

Soyuz 39 was a 1981 Soviet crewed space flight to the Salyut 6 space station. It was the fifteenth expedition, and carried the eighth international crew to the orbiting facility. The crew visited Vladimir Kovalyonok and Viktor Savinykh, who had reached Salyut-6 ten days prior.

Soyuz T-7 was the third Soviet space mission to the Salyut 7 space station. Crew member Svetlana Savitskaya was the first woman in space in almost twenty years, since Valentina Tereshkova who flew in 1963 on Vostok 6.

Soyuz T-13 was a Soyuz mission, transporting personnel to the Soviet space station Salyut 7. The eighth expedition to the orbital station, the mission launched from Baikonur Cosmodrome, atop a Soyuz-U2 carrier rocket, at 06:39:52 UTC on June 6, 1985. It is of note because it marked the first time a spacecraft had docked with a 'dead' space station, and the first time such a station had been returned to operational status following repairs.

Soyuz TM-4 1987 Soviet crewed spaceflight to Mir

Soyuz TM-4 was a crewed Soyuz spaceflight to Mir. It was launched on 21 December 1987, and carried the first two crew members of the third long duration expedition, Mir EO-3. These crew members, Vladimir Titov and Musa Manarov, would stay in space for just under 366 days, setting a new spaceflight record. The third astronaut launched by Soyuz TM-4 was Anatoli Levchenko, who returned to Earth about a week later with the remaining crew of Mir EO-2. Levchenko was a prospective pilot for the Soviet Space shuttle Buran. The purpose of his mission, named Mir LII-1, was to familiarize him with spaceflight.

Mir EO-4 Fourth expedition to Mir space station

Mir EO-4 was the fourth long-duration expedition to the Soviet space station Mir. The expedition began in November 1988, when crew members Commander Aleksandr Volkov and Flight Engineer Sergei Krikalev arrived at the station via the spacecraft Soyuz TM-7. The third crew member of EO-4, Valeri Polyakov, was already aboard Mir, having arrived in August 1988 part way through the previous expedition, Mir EO-3.

Salyut 6 EO-1 was a Soviet long duration space expedition, the first to dock successfully with the space station Salyut 6. The two person crew stayed were in space for a record setting 96 days, from December 1977 to March 1978. The expedition was the start of what would be the semi-permanent occupation of space by the Soviets.

Soyuz 6 EP-1 was a 1978 Soviet crewed space flight to the orbiting Salyut 6 space station, during the expedition EO-1. It was the third crewed flight to the station, and the second successful docking. It was also the first crew to visit an occupied station and marked the first time that three spacecraft were docked together. The launching spacecraft was Soyuz 27, and the crew of EP-1 are often referred to as the Soyuz 27 crew.
