Mission highlights

The flight carried 10 kg of equipment for use by Merbold in ESA's month-long Euromir 94 experiment program. During automatic approach to Mir's front port, the spacecraft yawed unexpectedly. Viktorenko completed a manual docking without additional incident.

Ulf Merbold German astronaut and physicist

Ulf Dietrich Merbold is a German physicist and astronaut who flew to space three times, becoming the first West German citizen in space and the first non-American to fly on a NASA spacecraft. He flew on two Space Shuttle missions and on a Russian mission to the space station Mir, spending a total of 49 days in space.

Salyut 2 Soviet space station which was launched in 1973

Salyut 2 (OPS-1) was a Soviet space station which was launched in 1973 as part of the Salyut programme. It was the first Almaz military space station to fly. Within two weeks of its launch, the station had lost attitude control and depressurized, leaving it unusable. Its orbit decayed and it re-entered the atmosphere on 28 May 1973, without any crews having visited it.

Timeline of space travel by nationality

Since the first human spaceflight by the Soviet Union, citizens of 42 countries have flown in space. For each nationality, the launch date of the first mission is listed. The list is based on the nationality of the person at the time of the launch. Only 3 of the 42 "first flyers" have been women. Only three nations have launched their own crewed spacecraft, with the Soviets/Russians and the American programs providing rides to other nations' astronauts. Twenty-seven "first flights" occurred on Soviet or Russian flights while the United States carried fourteen.

Soyuz TM-19 was a crewed Soyuz spaceflight to Mir. It launched on 1 July 1994, at 12:24:50 UTC.

Aleksandr Kaleri Russian cosmonaut

Aleksandr "Sasha" Yuriyevich Kaleri is a Russian cosmonaut and veteran of extended stays on the Mir Space Station and the International Space Station (ISS). Kaleri has most recently been in space aboard the ISS serving as a flight engineer for the long duration Expedition 25/26 missions. He has spent the fourth-longest time in space of any person, the longest time in space of any currently active cosmonaut, and the longest time in space of any person not born in what is now Russia.

Soyuz TM-3 1987 Soviet crewed spaceflight to Mir

Soyuz TM-3 was the third crewed spaceflight to visit the Soviet space station Mir, following Soyuz T-15 and Soyuz TM-2. It was launched in July 1987, during the long duration expedition Mir EO-2, and acted as a lifeboat for the second segment of that expedition. There were three people aboard the spacecraft at launch, including the two man crew of the week-long mission Mir EP-1, consisting of Soviet cosmonaut Aleksandr Viktorenko and Syrian Muhammed Faris. Faris was the first Syrian to travel to space, and as of June 2021, the only one. The third cosmonaut launched was Aleksandr Aleksandrov, who would replace one of the long duration crew members Aleksandr Laveykin of Mir EO-2. Laveykin had been diagnosed by ground-based doctors to have minor heart problems, so he returned to Earth with the EP-1 crew in Soyuz TM-2.

Soyuz TM-8 1989 Soviet crewed spaceflight to Mir

Soyuz TM-8 was a 1989 spaceflight which carried the fifth long duration crew to the Soviet space station Mir. It was part of the Soyuz-TM series of spacecraft, which were the fourth generation of the Soviet Soyuz. Soyuz TM-8 was the eighth crewed spaceflight to Mir, and spent 166 days in orbit.

Soyuz TM-18 1994 Russian crewed spaceflight to Mir

Soyuz TM-18 was launched from Baikonur Cosmodrome and landed 112 km north of Arkalyk. TM-18 was a two-day solo flight that docked with the Mir space station on January 10, 1994. The three cosmonauts became the 15th resident crew on board Mir. The crew did research work in space flight medicine, primarily by cosmonaut Valeri Polyakov during his long-term flight, and accomplished 25 different experiments.

Soyuz TM-30 Final crewed spaceflight to Mir

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.

Progress 1 Soviet unmanned Progress cargo spacecraft

Progress 1, was a Soviet unmanned Progress cargo spacecraft which was launched in 1978 to resupply the Salyut 6 space station.
