Three days after the launch of Salyut 2, the Proton's spent third stage exploded, due to pressure changes within the tanks. This explosion resulted in a cloud of debris, some of which followed a similar trajectory to the station. Ten days later this debris struck the station, damaging the hull and causing depressurization. Both solar panels were torn free, removing the ability of the station to generate power and control its altitude. Three pieces of debris from the station were catalogued, and had
decayed from orbit by 13 May. The remainder of the station
reentered the atmosphere on 28 May 1973 over the
Pacific Ocean. An inquiry into the failure initially determined that a fuel line had burst, burning a hole in the station. The damage from the debris collision was only discovered later. ==Fidel Castro tour==
