A near miss for the ISS?
For the third time in twelve years, the crew of the international Space Station
were required to retreat to escape capsules in the event of a collision with
a piece of space debris.
Nasa says it is actively tracking some 22,000 pieces of space debris, but there are millions of objects left over from decades of space travel drifting in Earth's orbit.
They range in size from smaller than a centimetre across to large chunks of rockets, defunct satellites or discarded fuel tanks.
