Apollo astronaut Neil Armstrong complains of undesirable effects affecting the skin, eyes and airways that could be related to exposure to the dust of the moon that stick into their space suits during their extravehicular activities and carried into their spacecraft. The findings could be terrible awakening for those dreaming the moon in the future.
Moon’s dust is composed of coated layer of thick and undisturbed dust not only ultra-fine which can be easily inhale but it could pose the risk of health problems, similar to breathing asbestos and volcanic ash.
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 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.
The dust -subjected to millenia of UV radiation, would penetrate deep into the lungs, and micro-gravity would only help in bringing the dust deep into the lungs.
Humans can only spent two to three days in the moon and that is living only in the spaceship with airtight suits. But with long term exposure even wearing protective gear could be harmful when inhalation because dust can easily stick and follow the astronauts back into the living quarter.
Dreaming the dramatic and lovely moonscape in the future will just end up in dreaming. Just look up and see the moon beautifully shines.
