Soyuz 40 was the 16th expedition to Salyut 6 and carried the ninth international crew. It also ended the first phase of the Intercosmos program by carrying Romanian cosmonaut Dumitru Prunariu and Soviet cosmonaut Leonid Popov to the station. In all, nine Intercosmos missions were launched between 1978 and 1981.
Soyuz 40 was the last of the original Soyuz spacecraft (due to its replacement by the Soyuz-T) and the last Soyuz spacecraft to dock with Salyut 6. During the crew's stay, Prunariu studied the Earth's magnetic field. Earth observations had to be delayed until the last day of the flight, when Salyut 6 passed over Romania in daylight. During this time the crew also tested the station's orientation system.
The Salyut programme was the first space station programme, undertaken by the Soviet Union. It involved a series of four crewed scientific research space stations and two crewed military reconnaissance space stations over a period of 15 years, from 1971 to 1986. Two other Salyut launches failed. In one respect, Salyut had the task of carrying out long-term research into the problems of living in space and a variety of astronomical, biological and Earth-resources experiments, and on the other hand the USSR used this civilian programme as a cover for the highly secretive military Almaz stations, which flew under the Salyut designation. Salyut 1, the first station in the programme, became the world's first crewed space station.
Interkosmos was a Soviet space program, designed to help the Soviet Union's allies with crewed and uncrewed space missions.
Salyut 3 was a Soviet space station launched on 25 June 1974. It was the second Almaz military space station, and the first such station to be launched successfully. It was included in the Salyut program to disguise its true military nature. Due to the military nature of the station, the Soviet Union was reluctant to release information about its design, and about the missions relating to the station.
Salyut 6, DOS-5, was a Soviet orbital space station, the eighth station of the Salyut programme. It was launched on 29 September 1977 by a Proton rocket. Salyut 6 was the first space station to receive large numbers of crewed and uncrewed spacecraft for human habitation, crew transfer, international participation and resupply, establishing precedents for station life and operations which were enhanced on Mir and the International Space Station.
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.
Soyuz 29 was a 1978 crewed Soviet space mission to the Salyut 6 space station. It was the fifth mission, the fourth successful docking, and the second long-duration crew for the orbiting station. Commander Vladimir Kovalyonok and flight engineer Aleksandr Ivanchenkov established a new space-endurance record of 139 days.
Dumitru-Dorin Prunariu is a Romanian cosmonaut. He flew in space aboard Soyuz 40 spacecraft and Salyut 6 space laboratory. He teamed with the Soviet cosmonaut Leonid Popov. The backup crew was made of Romanian candidate cosmonaut Dumitru Dediu and Soviet cosmonaut Yuri Romanenko.
Soyuz 28 was a March 1978 Soviet crewed mission to the orbiting Salyut 6 space station. It was the fourth mission to the station, the third successful docking, and the second visit to the resident crew launched in Soyuz 26.
Soyuz 30 was a 1978 crewed Soviet space flight to the Salyut 6 space station. It was the sixth mission to and fifth successful docking at the orbiting facility. The Soyuz 30 crew were the first to visit the long-duration Soyuz 29 resident crew.
Soyuz 31 was a 1978 Soviet crewed space flight to the Salyut 6 space station. It was the seventh mission to and sixth successful docking at the orbiting facility. The Soyuz 31 crew were the second to visit the long-duration Soyuz 29 resident crew.
Soyuz 33 was an April, 1979, Soviet crewed space flight to the Salyut 6 space station. It was the ninth mission to the orbiting facility, but an engine failure forced the mission to be aborted, and the crew had to return to Earth before docking with the station. It was the first failure of a Soyuz engine during orbital operations.
Soyuz 35 was a 1980 Soviet crewed space flight to the Salyut 6 space station. It was the 10th mission to and eighth successful docking at the orbiting facility. The Soyuz 35 crew were the fourth long-duration crew to man the space station.
Soyuz 36 was a 1980 Soviet crewed space flight to the Salyut 6 space station. It was the 11th mission to and ninth successful docking at the orbiting facility. The Soyuz 36 crew were the first to visit the long-duration Soyuz 35 resident crew.
Soyuz T-2 was a 1980 Soviet crewed space flight to the Salyut 6 space station. It was the 12th mission to and 10th successful docking at the orbiting facility. The Soyuz T-2 crew were the second to visit the long-duration Soyuz 35 resident crew.
Soyuz 37 was a 1980 Soviet crewed space flight to the Salyut 6 space station. It was the 13th mission to and 11th successful docking at the orbiting facility. The Soyuz 37 crew were the third to visit the long-duration Soyuz 35 resident crew.
Soyuz 38 was a human spaceflight mission conducted by the Soviet Union during September, 1980. The Soyuz spacecraft brought two visiting crew members to the Salyut 6 space station, one of whom was an Intercosmos cosmonaut from Cuba.
Soyuz T-3 was a Soviet spaceflight, launched on 27 November 1980 to the Salyut 6 space station. It was the first Soyuz spacecraft to carry three cosmonauts following the fatal Soyuz 11 disaster in 1971.
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.
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.
