This is all well and good except the current resident in the White House has cancelled the return to the Moon project and thus also killed the Mars program. It seems that the only thing they are interested in is for NASA to concentrate on Global Warming and nothing else. This is too bad and shows a tremendous amount of short sightness and too much political influence on what should be a purely scientific endeavour.
You all have the wrong idea... the president doesn't kill a program by himself. It congress. And if congress doesn't like the presidents decision they can over turn it. Its called Checks and balances... go back learn this about our country.
