Is it ordinary sand/dust or is it that super-abrasive stuff like what is found on the Moon?
Fair answer I was just thinking is it sand or like moon dirt haha.
☢☢☢ mine was a green house doom cover/solar power collector, fraction still with " plasma " collection pumps (for low Gravity mining) refinement condenser "bottles" for H2O, Helium 3 & what have the regolith + 6 individually directable & rotatable walking pads were for both movement & agitating overburden & to speed heating & outgasing = a thermal nuclear powered version is required for mining sweet spots in cold shadows in lunar crater bottoms where volatiles like helium 3 never evaporate
Why are the workers in white suits inside the arena thingy ? This is just sand is it not ?
cool
