NASA Focuses on Developing New Moon Craft - Yahoo! News
Now I don't want to sound stupid, but why does it take 12 years to develop a new craft to go to the Moon? If you look at the history from NASA attempts to do some manned or unmanned missions to the Moon date back to 1958, about 11 years before the first manned landing.
Thirty or so years ago we had a craft capable of landing on the Moon. It is not like they need to go back to the drawing board on this. Why so long?
As a side note - NASA's research will, eventually, affect the private sector much like how research in the military industry ripples out. It gives the economy a boost. I would rather see NASA getting the research money than the military.
