Mission highlights

The Mir crew welcomed aboard Anatoli Artsebarski, Sergei Krikalev (on his second visit to the station), and British cosmonaut-researcher Helen Sharman, who was aboard as part of Project Juno, a cooperative venture partly sponsored by British private enterprise. Sharman's experimental program, which was designed by the Soviets, leaned heavily toward life sciences, her speciality being chemistry. A bag of 250,000 pansy seeds was placed in the Kvant-2 EVA airlock, a compartment not as protected from cosmic radiation as other Mir compartments. Sharman also contacted nine British schools by radio and conducted high-temperature superconductor experiments with the Elektropograph-7K device. Sharman commented that she had difficulty finding equipment on Mir as there was a great deal more equipment than in the trainer in the cosmonaut city of Zvezdny Gorodok. Krikalev commented that, while Mir had more modules than it had the first time he lived on board, it did not seem less crowded, as it contained more equipment. Krikalev also noted that some of the materials making up the station's exterior had faded and lost color, but that this had no impact on the station's operation.

The spacecraft spent 144 days docked to Mir. While it was in orbit, the failed coup d'état against Mikhail Gorbachev in August 1991 rocked the Soviet Union, setting in motion events which led to the end of the Soviet Union on 26 December.

Out of the Present , a 1995 film documentary focused on cosmonaut Sergei Krikalev's stay on Mir, features the arrival of Soyuz TM-12.

<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.

Soyuz TM-7 was a crewed Soyuz spaceflight to Mir. It launched on 26 November 1988, at 15:49:34, and was the start of the fourth long duration expedition to Mir, Mir EO-4. The crew would join the third crew member of EO-4, cosmonaut/physician Valeri Polyakov, who was on Mir for the second half of EO-3. Also launched by Soyuz TM-7 was French astronaut Jean-Loup Chrétien, who would take part in the 24-day French mission known as Mir Aragatz. The spacecraft Soyuz TM-7 remained docked to Mir for the duration of EO-4. At the end of EO-4 in April 1989, due to delays in the launch schedule, Mir was left uncrewed, and all three EO-4 crew members were transported back to Earth.

Lasting from October 1991 to March 1992, the mission included cosmonauts from Austria and the soon-to-be independent region of Kazakhstan, as the Soviet Union collapsed in December 1991. The launch ceremony at the Baikonur Cosmodrome in Baikonur, Kazakh SSR was attended by the Soviet Premier Ivan Silaev, the President of the Kazakh SSR Nursultan Nazarbayev, and the Chancellor of Austria Franz Vranitzky. Before the launch, for the first time, President Nazarbayev received the launch report from cosmonaut Tokhtar Aubakirov in the Kazakh language.

Mir 20 was a harbinger of the multinational missions that would be typical of the International Space Station. After 179 days, 1 hour and 42 minutes on orbit, Reiter obtained the record for spaceflight duration by a Western European.

Soyuz TM-30, also known as Mir EO-28, was a Soyuz mission, the 39th and final human spaceflight to the Mir space station. The crew of the mission was sent by MirCorp, a privately funded company, to reactivate and repair the station. The crew also resupplied the station and boosted the station to an orbit with a low point (perigee) of 360 and a high point (apogee) of 378 kilometers ; the boost in the station's orbit was done by utilizing the engines of the Progress M1-1 and M1-2 spacecraft. At that time a transit between Mir and the International Space Station was already impossible - such a transfer was deemed undesired by NASA - and the orbital plane of ISS had been chosen some time before to be around 120 degrees away from that of Mir. The mission was the first privately funded mission to a space station.
