Anyone watching the spacewalk?
http://www.bbc.co.uk/news/science-environment-35320934I've just flicked over now and again.
The whole Tim in space thing is bloody fascinating, it helps that he's such a likeable character. The month he's been away has flown by.
I watched Stargazing live the other day (the one with Dara and Brian Cox) and am learning all sorts - did you know they have to have special tools in space? For example, the hammer - because every reaction has an equal and opposite reaction,when you hammer something in in zero gravity, you'd recoil quite badly so they have a hammer with ball-bearings in the head which take the impact. Also, the force of light can move the ISS, I can't go in to more details because it's science stuff, but up there, light shining on the ISS "wings" can move it.
