dust too fine
Tom,
I seem to recall that the possible dust would be too fine for brushing. Got a link somewhere in this list o' bookmarks...it's like my desk...a rather destrubed stratigraphy. If I find I'll post it. I've thought 'bout compressed air (argon) but the weight of canisters would be a pain. Handy to clean off the RAT'd surface, though.
I wonder if it goes into a big crater, will it be able to get out? And with winter coming, will the shadows in there cause power problems (ie in the shadow of the crater wall)?
