Breathing in Moon dust could kill you – BGR

Dreams of a lunar colony where people walk around on the dusty surface inside of big domes will remain a dream for a while longer. Vi kan til slutt nå et punkt hvor mennesker kunne feasibly skabe komfortable levevilkår på Earth's Moon, men ny forskning antyder at materialet som dækker vores nærmeste nabo er faktisk toksisk for mennesker. Takket være Apollo-missioner, forskere på jorden har eksempler på lunar dust that they can test, and a new research effort found that the pale powder is packed with compounds that react with human cells. As New Scientist reports, the minerals prompt the formation of hydroxyl radicals that are thought to promote lung cancer. When NASA visited the Moon many decades ago, they soon found out how hostile the lunar surface could ask. The dusty surface was tough on the space suits the astronauts wore as well as vehicles like the lunar rover. In another recent round of research, scientists exposed living cells from rodents and humans to a Moon dust analog. The cells did not go well, and some 90% of mouse brain cells and human lung cells eventually died after coming into contact with the faux moon dust. This is a pretty serious problem for any astronauts who aim to visit the Moon in the future. Equipping a sealed space suit to venture out onto the surface is easy enough (relatively speaking), but upon returning to a ship or &#821 1; in the more distant future – a lunar base, ensuring…

Renewed interest in the Moon over recent years has resulted in several planned missions to study Earth’s satellite more closely than in the past. Eventually, manned missions will indeed return, so it will be interesting to see how engineers plan on dealing with this “new” hazard.
