What a Little Moon Dust Can Do





"Lunar dust is extremely abrasive -- and unavoidable -- as astronauts quickly learned during the Apollo missions of the 1960s and '70s. Within hours, the dust covered the astronauts' spacesuits and equipment, scratching lenses and corroding seals."

I think we can safely expect a similar problem to plague astronauts on Mars.

Wasn't it in the War of the Worlds that the aliens were ultimately killed by germs? It's always the little things we have to worry about.

Mac, didnt you post something awhile back about some sort of skinning material that could be used as space-suits? I wonder how that stuff would hold up.

Speaking of germs, rge, in theory a manned mission would also have to carry the burden of not infecting possible life on other planets even if we think it doesnt exist.

Lunar dust to lunar dust. Martian ashes to Martian ashes.

Mac,

My guess is that they should design a new sort of space suit for those who are exploring Mars (and the moon too, for that matter). The bulky suits used for the Apollo missions look to be made of more than one piece, which would leave many a niche and crevasse in which dust could settle and lodge. Ideally, a new suit design should be less bulky and of one piece (much like a scuba diver's suit). I think, too, that something could be learned from the Bedouins of the desert who even to this day brave many a sandstorm. How do they protect themselves from the onslaught of sharp sand particles? Perhaps we can integrate those Bedouin secrets into our own space program...

I don't think this is true for Mars. If the dust was abrasive and corrosive the rovers would probably have died a long time ago.

You're forgetting those (probably wind-driven) "anomalous cleaning events" JPL's so fond of citing.

Martian soil is highly oxidized, and very fine-grained. It gets in and on *everything*. I experienced a bit of Mars on Earth while hiking the red rock formations in Sedona, Arizona. Red-orange dirt everywhere. Yikes!
