The only reason YOUR president O'Bummer cancelled America's manned space program is because Constellation wasn't HIS idea. What a blubbering, brain dead moron......Private commercial entities simply won't ever get mankind beyond very low earth orbit. We did that in 1961 for crying out loud. Why are politicians so narrow minded and brain dead? Space exploration used to be interesting and exciting. Now King B.O. has made it a playground only for the super wealthy. The sooner we get rid of this idiot Bozo, the better......for a lot of reasons.
