00:00 On this day in space.
00:03 In 1977, the Salyut 5 space station fell out of space and burned up in Earth's atmosphere.
00:08 Salyut 5 was a Soviet space station and part of the highly secretive Almaz military space station program.
00:14 It launched in 1976 and housed two crews of cosmonauts as they conducted military experiments and other scientific research in orbit.
00:21 Originally, four crewed missions were supposed to go to Salyut 5.
00:24 However, the third crew was unable to dock their spacecraft and had to return home.
00:28 The fourth mission had to be canceled because Salyut 5 was starting to run low on propellant for its main engines and attitude control system.
00:35 Salyut 5 couldn't be refueled, so it was deorbited and left to burn up in Earth's atmosphere.
00:40 And that's what happened on this day in space.
