Obama promises a future of NASA with trips to Mars on a time frame that exceeds his tenure as a 2-term President.
When JFK committed America to land on the Moon, his projected date would have fallen under his watch as a 2-term President.

The entire half-century budget of NASA equals the current two year budget of the US military.
Apollo in 1969. Shuttle in 1981. Nothing in 2011. Our space program would look awesome to anyone living backwards thru time.
