Soyuz 26 (Russian : Союз 26, Union 26) was a Soviet space mission which launched the crew of Salyut 6 EO-1, the first long duration crew on the space station Salyut 6.
The Soyuz spacecraft was launched on 10 December 1977, and docked with the space station the next day. Soyuz 27 arrived at the station in January 1978, and its two-person crew transferred into the Soyuz 26 spacecraft to undock and land a few days later.

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.
Soyuz 10 was launched on 22 April 1971 as the world's first mission to the world's first space station, the Soviet Salyut 1. The docking was not successful and the crew returned to Earth without having entered the station. It would be the first of numerous docking failures in the Soviet space station program.
Soyuz 12 was a 1973 crewed test flight by the Soviet Union of the newly redesigned Soyuz 7K-T spacecraft that was intended to provide greater crew safety in the wake of the Soyuz 11 tragedy. The flight marked the return of the Soviets to crewed space operations after the 1971 accident. The crew capacity of the capsule had been decreased from three to two cosmonauts to allow for pressure suits to be worn during launch, re-entry and docking. It was the first time pressure suits were used for reentry since the Voskhod 2 flight.
Soyuz 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.
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 5, also known as OPS-3, was a Soviet space station. Launched in 1976 as part of the Salyut programme, it was the third and last Almaz space station to be launched for the Soviet military. Two Soyuz missions visited the station, each manned by two cosmonauts. A third Soyuz mission attempted to visit the station, but failed to dock, whilst a fourth mission was planned but never launched.
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.
Soyuz 14 was a 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 for the joint Apollo-Soyuz flight of 1975.
Soyuz 15 was a 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.
Soyuz 16 was a 1974 crewed test flight for a joint Soviet-US space flight which culminated in the Apollo-Soyuz mission in July 1975. The two-man Soviet crew tested a docking ring and other systems to be used in the joint flight.
Soyuz 28 was a 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 27 was a 1978 Soviet crewed spacecraft which flew to the orbiting Salyut 6 space station, during the mission EP-1. It was the third crewed flight to the station, the second successful docking and the first visitation mission. Once docked, it marked the first time that three spacecraft were docked together.
Soyuz 25 was a 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.
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 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 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.
The Soyuz 40 mission was a 1981 Soviet crewed spaceflight and the final flight of the Soyuz 7K-T spacecraft. It was a collaboration between the Soviet Union and Romania.
Soyuz T-15 was a crewed mission to the Mir and Salyut 7 space stations and was part of the Soyuz programme. It marked the final flight of the Soyuz-T spacecraft, the third generation Soyuz spacecraft, which had been in service for seven years from 1979 to 1986. This mission marked the first time that a spacecraft visited, and docked with, two space stations in the same mission.
Progress 2 was an unmanned Progress cargo spacecraft launched by the Soviet Union in 1978 to resupply the Salyut 6 space station. It used the Progress 7K-TG configuration, and was the second Progress mission to Salyut 6. It carried supplies for the EO-2 crew aboard Salyut 6, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres.
