Salyut-7, the Soviet orbital station, which worked in orbit for six years and carried six crews, after a communication session a minute ago, dived into the orbital night and no one - neither at the MCC in the city of Korolev, nor at the MCC in Houston - could know that she won't be back in touch. Something terrible happened to her. This event from the chronicles of those years provides evidence that in the world there was intense competition for space and space technologies between the USSR and the USA, sometimes coming to the brink of a nuclear disaster. And it all started because Yuri Gagarin was the first in space.
