Selecting a Mars crew is tricky: You need good engineers who are also crazy enough to believe they'll survive: we call it the Matt Damon Complex. _We_ know they'll die, but we need to build up the base so one day a crew won't, so I interview them and give them the best equipment we have, and send them there to die.
Even when the base is finished I won't go. It might be an historical trivia for most, but to me Mars' sands will always be too close to the color of dried blood.
