Salyut 7

Salyut 7The Soviet Union launches the last of the Salyut space stations, Salyut 7, into Earth orbit. Reflecting an ongoing significant rethink on space station construction, Salyut 7 is intended from the outset to be docked with additional modules to expand its habitable and working space. It also sets a new endurance record of its own, remaining in orbit for nearly a decade.
