I thought I mentioned that part of the nanomachines' purpose was to provide a protective shield.
As for not having that level of wave-tech yet... Well, if I recall correctly, Mars doesn't get a real working atmosphere until later after we work the
kinks of handwavium out beyond the Slap-Stick factor (besides, you can't tell me that someone like The Professor isn't working on making their own
nanomachines). At least, that's what I thought. Please correct me if I'm wrong about this here.
