moon and mars basically the same thing? O_O the radiation earth||mars and earth||moon are quite different in both duration and intensity. I believe its something they really haven't figured out. speaking of duration, that's a big deal in both fuel and effect on human passengers. but lets get to the important stuff, mars is actually a planet, with an atmosphere. saying the two are equivalent is more or less saying kicking a field goal outside on a windy day is the same as kicking one in a dome. except when you miss everyone dies. you also need 5x escape velocity from mars (we want them to come back too), which means more fuel and landing with lots of fuel. or at the very least sending fuel prior and hope nothing happens to it.
