Lunar Dustbusters

Maggie McKee writes "Moon dust could be a source of oxygen and metals. But moon dust could also lodge in astronauts' lungs, possibly triggering long-term health effects. During the relatively short Apollo Moon landing missions nearly 40 years ago, astronauts reported difficulty breathing. So now, before astronauts return to the moon in 2020, NASA is working on a number of ways to reduce the amount of lunar dust astronauts are exposed to — from simple grates on the floor to magnetic wands and giant lint rollers."

    Why is Lunar dust so different than "normal" dust and/or sand that we breathe and/or eat every day?

    Because it has not been smoothed down by water and wind. Only hits of meteorites scatter stuff there, and that is not enough to smooth away edges on grains of silica and other rough rocks.

    Anyhow, the solution is simple: Have the astronauts take up smoking so that they have practice :-)

    Actually smoking may be benificial here. The dust would tend to stick to the tar rather than scatter freely. Just look at the inside of a computer from a smokers house... the fans a gummed up, sticky dust covers everything and canned air does nothing on the tar laced dust. Mabe the tar can be used to help clean the dust from the air? NASA should give me funding to test this theory :-) Maybe the astronauts shouldn't smoke themselves but a tar derived from smokers homes could be used in air filters or something.

    Wipe your feet off before entering the airlock Um... did you not read?

    "It turns out what we did in Apollo was probably the worst way we could have handled it operationally," says Kriss Kennedy, project leader for architecture, habitability and integration at NASA's Johnson Space Center in Houston, Texas, US. That is because the Apollo landers did not have airlocks, so the astronauts had to live among the dust for days.

    Actually one of the problems with lunar dust is that it has a charge. Imagine sticking your arm in a box of packaging peanuts and pulling it out and have a number of the peanuts stuck to your arm. It's along that type of concept. The other big issue with lunar dust is that it's very abrasive. I believe in the original lunar missions, when they scooped up lunar dust into containers, it cut the o-rings on the containers that they brought the lunar dust back in.

    I am currently involved in an experiment to use a circuit board to remove the lunar dust from solar panels in lunar gravity. If you tried and brushed it off, it would scratch the glass and the solar panels would become less efficient. The circuit has been proven before, but we're (as far as I know) the first ones to try it in lunar gravity. Hopefully this concept can be adapted in the future to create a lunar dust "vacuum cleaner" or maybe apply it to "repel" dust in other ways.

    Breathing hard vaccuum is a really bad idea, so most space suits likely to be worn will be 100% isolated from the outside. This means that the only possible place for dust to get into lungs would be in the landing capsule - if the helmets are removed. Let's say, however, that they are not. That the astronaut simply connects to a piped oxygen supply when in the capsule. Then the risk of contamination is greatly reduced. Not eliminated, but reduced.

    You should read the Apollo Lunar Surface Journal. Sleeping in the suits was found to be very uncomfortable, even for the short missions (Apollo 11-14). Even then they had to take their helmets off to eat and drink.

    Lunar dust is so fine it sticks to everything and gets into everything. Even Armstrong and Aldrin, who were only out for just over two hours, were absolutey covered with the stuff.

    The longer missions being planned for the future will need to have a proper airlock area where the crews can strip down to their skin, shower, and only then enter the living area. The airlock would also be used to maintain suit fabric and seals, which are the real problem IMO because the dust is so abrasive.

    Worse.

    Moon dust off the surface has been nicely activated by radiation and sun over centuries. It is not the relatively inert silica you get from cutting glass and rocks. It can catalyse all kinds of strange and wonderfull reactions because cosmic ray particles have kicked out (or even modified) an atom here and there and it has remained there in a very active form due to the lack of atmosphere. On earth it would have been deactivated nearly immediately by oxygen, water or even nitrogen from the air. On the moon it will stay active nearly for ever and over the years there will be more and more of these on the surface of each particle. Add to that the habit to accumulate static charges (which is actually related to the surface being active) so it sticks everywhere and you got yourself a really nasty problem on your hands.

    Moon dust is something you do not like having anywhere near lungs and in fact anywhere near the innards of a space station. Think of asbestous, but with nearly instantaneous effect and the habit to cling to everything.

    In the 60-es they did not care about health and safety. Nowdays, this would be considerably more difficult to ignore.
