There is beating water on the surface of the moon. Does this have any significance for the future interstellar migration of mankind?

According to a report on the website of NASA on March 10, a paper published in the monthly Geophysical Newsletter of the United States explains how the measurement of the sparse molecular layer temporarily attached to the moon surface by the Lyman Alpha Mapping Project (LAMP) carried by LRO can help describe the changes of hydration on the moon in one day. However, scientists have recently discovered that there is water on the surface of the moon, and sparse water molecules will combine with the soil or weathering layer on the surface of the moon. With the change of daily time, their number and location are also different. This kind of water is more common in high latitudes. When the surface of the moon gets hot, it tends to jump around. According to the report, water molecules are tightly attached to the weathered layer until the surface temperature of the moon reaches its peak near noon. At this time, water molecules will be released from the weathering layer and then bounce back to the nearby place where the temperature is low enough for water molecules to attach; Or rise to the moon's extremely thin atmosphere or outer atmosphere. Once the temperature drops again, the water molecules in the atmosphere will return to the surface of the moon.

This study reveals the energy required to separate water molecules from lunar materials, which helps scientists understand how water is combined with lunar surface materials. Amanda Hendricks, the first author of the paper and a senior scientist at the American Institute of Planetary Science, said: "These research results will help us understand the water cycle of the moon and ultimately help us understand where humans can get water in future missions to the moon." He pointed out: "it is possible for human beings to use the water on the moon to make fuel, prevent radiation or conduct thermal management;" If these materials do not need to be transported from the earth to the moon, the cost of future lunar exploration missions will be lower. "

After we invented the telescope, we began to observe the moon overhead at night and found some features of the moon, such as the moon sea, mountains, craters and radiation patterns. I want to say one thing first. The moon sea is not a sea, and it was mistaken for a liquid ocean before we knew it. Later, it was found to be a very flat plain, a hollow filled with lava and volcanic ash.

The largest moon sea covers an area of 5 million square meters, accounting for half of our front moon, while there are only three on the back. How was the Moon Sea formed? Scientists think it may be caused by the collision of comets and asteroids with the moon. There are many mountains on the moon that are more spectacular than those on the earth. The highest mountain is near the south pole of the moon, 9 kilometers high, which is higher than Mount Everest. Many craters on the moon have central peaks, and some craters are located on older craters. There are many craters on the moon, and it is estimated that there are more than one million craters with a diameter exceeding 100 meters.
