Don't get me wrong, im all for space adventure and going to infiniti and beyond but 2 billion for 3 years doesn't seem right to me. I don't think much is going to happen in the next 3 years that hasn't happened in the last 300. As for the people who say "but what if there is an asteroid coming towards earth?" Well I hate to burst your bubble but armageddon wasn't based on a true story, so as for me I would rather just not know the whole world is going to end 3 years in advance because something tells me that might cause some panic. and the truth is Bruce Willis IS NOT WALKING THROUGH THAT DOOR!
p.s. I believe we are still in an economic crisis, and 2 billion seems like a little much to be throwing around on a fucking telescope. I bet you could find a new hubble telescope on Craigslist for like $1,700.
