Abstract :
Are we going to go to Mars or not ? Now would be a good time to decide. Are you listening, President Obama? Yes, the president has lots of things on his mind. But that´s true of any president, anytime. And the fact is, the U.S. government is already spending billions of dollars a year on a space program that has a trip to Mars as its ultimate but inadequately funded and too-far-off-to-get-excited-about goal.
