1973 April 3...Launch Vehicle: Proton-K. LV Configuration: Proton-K 283-01...Salyut 2
Salyut 2, the first Almaz station, reached orbit on April 3, 1973. Soon after, Salyut 2 lost stability and began tumbling. In 1992, Mikhail Lisun, backup cosmonaut for the Soyuz 24 flight to Almaz station Salyut 5, attributed the loss of Salyut 2 to an electrical fire, followed by depressurization. Salyut 2 broke up on April 14, and all trackable pieces reentered by May 28, 1973.
