The Salyut programme (Russian: Салю́т, IPA: [sɐˈlʲut], Salute or Fireworks) was the first space station programme undertaken by the Soviet Union, which consisted of a series of four crewed scientific research space stations and two crewed military reconnaissance space stations over a period of 15 years from 1971 to 1986. Two other Salyut launches failed. Salyut was, on the one hand, designed to carry out long-term research into the problems of living in space and a variety of astronomical, biological and Earth-resources experiments, and on the other hand this civilian program was used as a cover for the highly secretive military Almaz stations, which flew under the Salyut designation. Salyut 1, the first station in the program, became the world’s first crewed space station.
