Soyuz 28

The Soviet Union launches the Soyuz 28 mission, the first manned flight in its Interkosmos series of international space missions. Cosmonaut Vladimír Remek is the first Czech in space, as well as the first space traveler not born in the Soviet Union or the United States; along with Soyuz 28 mission commander Alexei Gubarev, Remek visits the Salyut 6 space station for several days, though is presence is purely political showmanship; Remek later reveals that he had few actual functions to perform during the flight. Soyuz 28 spends a total of nearly eight days in space before returning to Earth.
