    The Moon is Layered in Dust Bathed in Radiation

    The Moon is Layered in Dust Bathed in Radiation

    By Eddie Wrenn

    Living on the moon is surely humanity's goal as we make our first baby steps into space.

    But our constant neighbour may not treat us so well - for scientists now think that the very dust on our luna partner is poisonous to humans.

    The surface of the moon is coated in a layer of thick, undisturbed dust, which is not only ultra-fine - and therefore easy to inhale - but can increase the risk of various cancers, similar to breathing asbestos and volcanic ash.

    Researchers from the University of Tennessee, referring to Neil Armstrong's first steps onto the moon, said: 'The Apollo astronauts reported undesirable effects affecting the skin, eyes and airways that could be related to exposure to the dust that had adhered to their space suits during their extravehicular activities and was subsequently brought into their spacecraft.'

    Humans have only spent, at max, two or three days on the moon in total, and this time has often been spent in spaceships or airtight suits.

    But with long-term exposure, the team says that inhalation would be harmful - even when wearing protective gear, as dust trails the astronauts back into living quarters.

    Once inside the lungs the super-fine, sharp-edged lunar dust could health issues, affecting the respiratory and cardiovascular system, causing airway inflammation and increasing the risks of various cancers.

    The dust -subjected to millenia of UV radiation, would prentrate deep into the lungs, and micro-gravity would only help in bringing the dust deep into the lungs.

    The sharp 'regolith' of the moon is also believed to be as sharp as glass, without years of erosion like on earth, causing skin and eye damage. And a scratched cornea, while perhaps just an irritant on Earth, could cause havoc on a space mission.

    Now, walking on the surface of the moon is never going to be in our long-term plans, as breathing is the primary issue. But the ever-constant dust of the moon may curtail our adventures into the stark grandness of the moonscape outside whichever space bases we build in the future.

    Surely if you just wet the ground with some kind of liquid (dense enough to not evaporate in the moons weak gravitational field) the dust would form a cement solving the problem?

    I think if man returns to the moon to establish a permanent base, those bases will simply employ some sort of airlock/cleaning room in which as much of the lunar dust as possible is removed from the space suits of the astronauts before they are allowed to enter the habitation areas.

    Manufacturing a liquid agent in situ on the moon in sufficient quantities to dampen the surface would be an extremely costly process with would tie up resources that could probably be invested more fruitfully elsewhere.
    Close observation may result in feelings of horror, wonder and awe at world you find yourself inhabiting.
