Presumably also, the impact of dust in equipment and indeed, if its
brought inside needs a great deal of scrutiny. I mean even on the ISS
and shuttle some mechanical items seem t fail due to microscopic
particles getting in where they do not belong, the problem will be
thousands of times worse on a planet with dust.
Well, there is a great potential source of funding for a mars expedition.
Get Johnson&Johnson to dish out billions in advertising so that the crews
can then be see using "Pledge" to remove the dust from the furniture
inside the habitable volume :-)
Perhaps the solution lies in a different airlock design. You might need a
"cleaning" stage where dust on suits would be blown off and vented to
mars atmosphere, and a "suiting room" between the cabin and the airlock
where there would be no air circulating back to the habitable volume so
that residual dust from suits would not flow into cabin, and any dust
generated while crews get in or out of the suits would be filtered or
vented to mars.
Another issue: How to prevent our human flora from contaminating the
Martian landscape.

Re: New Spacesuit Design? ... It apparently really got all over the EVA suits, particularly the bottom half of the suits. ... Any dust they kick up will fly on a ballistic course in the vacuum, and in the low lunar gravity that means that dust you kick up could travel quite some ways before recontacting the lunar surface. ... Other than the annoying affect of lugging it back into the habitat with you, and the abrasive effects on the suit's exterior, this stuff could also scratch up your transparent helmet and protective UV visor, and cause your suit's exterior to become dark enough to the point where it's getting a lot hotter in the sunlight, causing the materials it's made out of to overheat and fail, and putting a increased load on the cooling system of the suit. ...
