How does anything heading into space avoid all this lot?

Well the earth is a lot bigger than it looks in that video. If I said there were 13,000 humans in Wales you'd not worry about accidentilly running into one. And the further out those satelites are the more "sapce" there is to use up.

"Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."

They have a projection of this at the Science museum....the earth is surrounded by about 40,000 satellites....it's an absolute swarm of the buggers. I wonder if there could ever be a chain reaction where one small collission could send out debris that hit a load of other satellites and so on a so fourth until the whole thing became unstable.

Relatively although it sounds like it's crowded it is comparable to placing a single marble in the middle of Ireland then throwing another one from mainland Britain and being worried about the 2 hitting each other.

Oh okay...so I can take the colander off my head and stop panic buying tinned food then?

It's not the stuff you can see that's the problem, it's the little crap, flecks of paint, screws, that sort of thing, they are all potentially travelling very fast relative to a vehicle, lots of kinetic energy and pretty much invisible.

It's not just the satellites, there's loads of other 'space stuff' (technical term) stuck in orbit like bits of old rockets and various debris.

Bugger now I'll be at the back of the queue of panic buyers!

If anyone hasn't been for a while the Space section at the Science Musuem really is rather good. thumbup I'll be giving that whole 'Welcome' wing a miss next time though.

If Google earth is a collection of satellite pictures, taken by some of those 13,000 satellites, there must be more satelittes taking pictures of those 13,000 satellites in google earth. So just how many satellites are there?

Somewhere around 40,000 I think.

As an aside I convinced a girl in the office that Google Earth images on my Ipod Touch were live, and that I had watched her drive from her house to the train station yesterday morning and was keeping "an eye on her" hehe
