Huge PR move, but i dont think it's gonna work. Do people really need to "send a human" to mars? To prove what to whom (the soviets are no more). It's not like we haven't already been there and taken our pictures. Or that we expect any surprises from this mission. How about we make a plan to terraform Mars? Or to work on more mysterious things like genomes, like the brain etc? Sending a human to mars is a PR move, maybe typical of our times, but not useful.
