Soyuz T-12 was the seventh mission to visit the Salyut 7 space station and the second to visit the long-duration Soyuz T-10 resident crew of the station. The mission began on July 17, 1984, 17:40:54 UTC, launching Commander Vladimir Dzhanibekov, Flight Engineer Svetlana Savitskaya and Research Igor Volk into orbit. They docked with the station the next day. During their 9-day stay on the station, crew carried out various experiments, and Savitskaya became the first woman to ever perform a spacewalk. The mission concluded with a safe landing back on Earth on July 29, 1984, 12:55:30 UTC.
The Soyuz-U2 was a Soviet, later Russian, carrier rocket. It was derived from the Soyuz-U, and a member of the R-7 family of rockets. It featured increased performance compared with the baseline Soyuz-U, due to the use of syntin propellant, as opposed to RP-1 paraffin, used on the Soyuz-U.
Soyuz T-15 was a Soyuz spacecraft which launched on 17 July 1984 17:40 UTC. It transported two cosmonauts of EP-4 to Salyut 7. The EP-4 crew was Vladimir Dzhanibekov, Svetlana Savitskaya, and Igor Volk.Soyuz Details

The Soviet space program, was the national space program of the Union of Soviet Socialist Republics (USSR) actived from 1930s until disintegration of the Soviet Union in 1991. The Soviet Union's space program was mainly based on the cosmonautic exploration of space and the development of the expandable launch vehicles, which had been split between many design bureaus competing against each other. Over its 60-years of history, the Russian program was responsible for a number of pioneering feats and accomplishments in the human space flight, including the first intercontinental ballistic missile (R-7), first satellite (Sputnik 1), first animal in Earth orbit (the dog Laika on Sputnik 2), first human in space and Earth orbit (cosmonaut Yuri Gagarin on Vostok 1), first woman in space and Earth orbit (cosmonaut Valentina Tereshkova on Vostok 6), first spacewalk (cosmonaut Alexei Leonov on Voskhod 2), first Moon impact (Luna 2), first image of the far side of the Moon (Luna 3) and unmanned lunar soft landing (Luna 9), first space rover (Lunokhod 1), first sample of lunar soil automatically extracted and brought to Earth (Luna 16), and first space station (Salyut 1). Further notable records included the first interplanetary probes: Venera 1 and Mars 1 to fly by Venus and Mars, respectively, Venera 3 and Mars 2 to impact the respective planet surface, and Venera 7 and Mars 3 to make soft landings on these planets.WIKI
