The world’s first space station, the Soviet Salyut 1, was launched in 1971. The cosmonauts aboard the Soyuz 11 spacecraft were the first to enter, remaining aboard for 22 days. By 1982, five more Salyut space stations had been orbited successfully, two of them for military purposes. By rotating the crews regularly, the Soviets were able to staff the stations for extended periods. All the Salyut space stations decayed and are no longer in orbit. What happened to Salyut 1? Discuss
