Colour me VERY skeptical. That's simply way too expensive and risky. Besides, I've heard that the American congress wasn't very happy with NASA's habit to burn through funds without presenting valid technical solutions, consistent plan, and clear roadmap for mission. It looks like there are too many improvisations going on behind the scene.
Space agencies around the world should focus onto establishing permanent base on the Moon: to me, this looks like only logical step forward. Leave Mars to automatic probes and landers for the time being, and let's not try to bite more than we can chew
