Am I the only one who thinks this is a damn waste of money? Are they going to learn anything on Mars that will feed the hungry on earth, help us fix what we've screwed up in our atmosphere, replace what we've used up & wasted, cure any diseases?? Anything fricken useful for real anyone other than scientists and academics??
Google Neil degrasse Tyson and NASA budget. That will get you a long way towards understanding why stuff like this is not frivolous.
