alt Hacker NewsOr effective decontamination performed in the airlock. There was a recent demonstration of an electrostatic repulsion device reducing dust on suit fabric which might help with sticking. And an air shower like used for clean rooms does not seem too far out.
Is that required?
Could the suit itself be used as a type of airlock, to leave outside things outside?
For example, mounting yourself onto a wall, then the back/whatever of the suit opens to the inside, and you hop out? (yes, there would be some dust recovery required, but minimal in comparison)
