The six crewmen squeezed into two Russian Soyuz escape craft after the fast-approaching debris was picked up on Space Station radar.
The astronauts prepared for an emergency return to earth but the space junk flew by – narrowly averting a major space catastrophe by 800 feet.
The near miss was at 21.08 GMT.
The Pentagon warned recently that a space junk collision was an increasing threat.
An abandoned satellite travelling at 17,000 mph would anhihilate the International Space Station.
Military data , TV signals, weather forecasts, GPS navigation and international phone connections could be knocked out by such a collision.
