Argument: Committing to Mars will inspire NASA to make it happen
"Why we must go to Mars." On to Mars: "There are additional reasons to send humans to Mars. Nations, like people, thrive on challenge; they languish without it. The space program needs a challenge. Consider these statistics: Between 1961 and 1973, with the impetus of the moon race, NASA produced technological innovations at a rate several orders of magnitude greater than that it has shown since. Even so, NASA's average budget in real dollars then was only about 20 percent more than today ($16 billion 1998 dollars compared with $13 billion). Why the enhanced productivity? Because NASA had a goal that forced its reach to exceed its grasp. Far from being a waste of money, having NASA take on the challenge of a manned mission to Mars is the key to giving the nation a real return for its space dollars."
