Greatest spacecraft collision

On 25 June 1997, an unmanned Progress supply vehicle, weighing 7 tonnes (15,000 lb), collided with the Russian Mir Space Station. Cosmonauts Vasily Tsibliev and Alexander Lazutkin on board Mir had to work quickly to seal a breach in the hull of Mir's Spektr module, while US astronaut Michael Foale prepared Mir's Soyuz capsule for a possible evacuation. Although the loss of life was avoided, the station was left dangerously low on power and oxygen and temporarily tumbling out of control.
