It shouldn't be difficult to also train them in things like setting broken limbs. Agencies including NASA are researching just how much medical training ought to be provided. The idea is to have it where any of the crew can perform major surgery, with advice from medical officers in ground control. They haven't necessarily all been through medical school (though you could require that all of the crew be MDs -- there actually are enough MDs in the astronaut corps already to do that), so it's not a situation you'd want on the ground, but it would suffice for this sort of a situation.<br /><br />This isn't something nobody's considered before, nor even something unique to spaceflight. Researchers in remote locations (such as the South Pole) face this possibility every day, and so do soldiers deep behind enemy lines. Of course, the soldiers actually have it worse -- they may not be able to use radio communications for days if they need to avoid revealing their position, whereas a Mars-bound crew only has to cope with the round-trip lightspeed signal time. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
