If you think space is simply full of dust and cosmic rays, you should ask astronaut Jim Lovell what space if full of. He might well tell you.

For Jim Lovell knows all about space - he was the leader of the famous space mission 'Apollo 13', also available as a film.

During the mission, Lovell's spaceship collided with a piece of space debris, which caused it to quite literally 'go wrong'.

Luckily, Lovell repaired the spaceship with some kind of pipe-thing, and eventually got back home and then the film ended.

However, in real life space, the object that caused the near-catastophe was recently identified as a space-sliver: the sharpest object in space!
