No idea who NDT is, but I'm kind of afraid that doing something like a Mars mission too early will turn out having the opposite effect. With the tech available for a soon-ish to launch Mars mission, chances are pretty high that something would go wrong catastrophically, there's just so much complexity that cannot break down for such a long time under extreme conditions, we're not ready for that. Watching the people we send there die slowly and horrifically isn't going to be a rational "we knew the risks" thing for the general public, people will be horrified and it'll put a big damper on future endeavors of this kind. I'd expect manned spaceflight to be pretty much dead for decades after that.
