The return to the natural satellite of our planet is expected in 4 years. There is very little time until then, so it's high time to find out just how extreme the conditions will be for the first colonizers there. It turns out that it will not be easy for them to survive there, but after all, there are no obstacles that a person cannot overcome.
As part of the Chang'e-4 mission, instruments designed to measure radiation were placed on board the lunar lander. The device landed on the side of the Silver Globe surface invisible from Earth. The instruments recorded radiation at the level of about 60 microsieverts per hour.
This means that the radiation there is about 300 to 1000 times higher than that to which we are exposed here on Earth, about 5 to 10 times higher than during a long-haul flight and about 2.6 times higher than that experienced by astronauts. on the International Space Station. In truth, it is not a lot, and yet such doses endanger the health and even life of astronauts. Why?
Because they will be spending months or even years on the lunar surface, not several days, as in the Apollo mission. NASA is planning a flight to this globe not to get it, because it already happened 50 years ago, but to stay there forever. It is therefore about building a colony and starting the era of space mining in order to obtain resources torrent sites directory the development of the first cities. Prolonged exposure to radiation can affect the health of astronauts. So NASA is planning to build bases in caves or below the surface to reduce this problem.
Scientists also spend sleep on regolith, that is, lunar dust. Already during the Apollo Silver Globe mission, astronauts complained that contact with regolith caused them unpleasant sensations. Although the astronauts always wore space suits during their missions, when they returned to the spaceships they took them off and then they sneezed and watered their eyes.
Engineers at Stony Brook University School of Medicine conducted an experiment involving moon dust. It turns out that it is much more dangerous to people than we previously thought. Moon dust not only destroys cells in the human body, but can also damage the genome.
Undoubtedly, this is a huge problem, because regolith will be very hard to deal with. This dust is extremely fine and is electrified with high-energy particles from the sun. It can settle on suits, get inside bases or space stations and spread there.
Scientists set up an experiment in which they used live cells from mice and humans and then exposed them to artificially prepared lunar dust. In the long run, dust damages cells and even changes their DNA. Unfortunately, it is not known exactly why lunar dust has such a degrading effect on cells and DNA. It's probably about its size and shape, which allows it to get into the lungs and then into the bloodstream. More research is needed in this matter.
