Space Junk

I just watched the documentary "Collision Point" that is an extra feature on the Gravity DVD. Around 16:37 a guy says that it will soon cost $1B to prevent 1 collision.

If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ...
