Theres only one way to get to Mars in the next 20 years and thats using one way trips. Colonization...thats the ticket. Just keep sending crap down to the surface and let the colonists figure it out. Unfortunately we would rather play in the sand and kill a couple hundred thousand folks than invest in space technology, so I doubt we will ever go.
Although I don't own any shares and don't want USEC stock to go down, If it does go to $0.76 I'd be a buyer!
My two biggest concerns for USEC are 1) Strengthening dollar making its product more expensive overseas 2) Too much EU exposure. Europe is not just collapsing, its also turning anti-nuke. That's a double whammy!
