Search for water on the moon thanks to space exploration devices

The question is whether there is water on the moon? And if so, where will water come from?

1. "Clementine" moon probe device

The Earth and the moon are in the same area in the sky, so once the Earth has been subjected to a few times from a comet's impact, it is not an exception. The problem, however, is that even water on the moon does not mean that water can be found on the moon. The moon in the daytime temperature is more than 100 degrees Celsius. With such a temperature it is easy to melt ice, boil and evaporate.

Moreover, the gravitational force on the moon is very weak, only 1/6 of the earth, not enough to escape evaporation into space. Therefore, it is thought that if there is water on the moon, water can only be distributed in dark meteorite niches, where the sun never reaches, temperatures below minus 240 degrees Celsius. Such low temperatures are enough to have an amount of ice still existing.

On January 25, 1994, the United States fired into space a moon probe called "Clementine". However this expedition failed. On February 6, "Clementine" began to fly around the moon, photographing the surface of the moon, and began to take measurements. In it there is an experiment to broadcast radio power in the area of ​​the rock niche near the south pole of the moon. This wave after the reflection has been received by the radio device on earth. After scientists analyzed this electric wave, it was discovered that those reflected waves almost came from materials that contained ice water.

The "Clementine" sky reconnaissance device captures the moon's southernmost area.

Such results are very reasonable and coincide with human speculation. However, when astronomers used Puerto's Arecibo radio telescope to find ice water in dark and deep rock holes, they found no similar results. So is there water in the pits in the end?

2. Theory of "cold wells"

Years before the 7th century, the thought of approaching the moon's surface to find water began to take shape. At that time, a scientist named James Arnold from the University of California (USA) pointed out that the holes, the hollows of the rock on the surface of the moon had no sunshine, so it was very cold and where water is concentrated with other volatile substances. That place might be called "cold well".

"Cold well" is like a cool cup of iced tea in the middle of summer. If you look closely at the iced tea, you will see them as sucking water molecules from the air and condensing them into tiny droplets. The "cold well" here also works like ice tea.

Since 1994, artificial shock scientists have impacted on the dust in the pit, the rock cavity, then used spectrophotometers at close range to measure whether there is a water component? Such experiments have been repeated many times.

3. Water comes from the moon land

In addition to being able to contain water in rock pits, will water still exist in the lunar soil?

In October 2008, India's "1-moon number" was shot into space, on which a set of equipment was provided by the US Aviation Department called "moon mineral drawing device." " . This device, through reconnaissance of light wave fields reflected on the moon's surface, shows traces of water and hydroxide on the moon. This device has been detected in a reflected optical wave that lacks the ultraviolet ray wave field, which indicates that the beam of light was absorbed by the water molecule.

Drawing from "Moon mineralogical drawing device", green color indicates the existence of water.

At first scientists did not believe in this result, but very soon they found evidence elsewhere.

Scientists speculate that in every cubic meter of the moon's surface, about 1 liter of water is present, they exist at the very thin surface of the top floor in the lunar soil. Previously, scientists thought that if there was water on the moon, it could only exist in the darkest shadow area, while other areas were completely arid. Now, the new discovery has proven that the truth is not exactly that, but water also exists under the moon. This is a great breakthrough for humans in finding water on the moon.

4. Water is present in moon rocks

Assuming the "strong collision theory" explains the true origin of the moon, the inside of the moon is also likely to have a certain amount of water. Because after being hit, it is very likely that water will accumulate inside the moon.

As long as you have a normal telescope, you can see that there are large and small holes on the surface of the moon. They are created by the impact of small planets, comets and meteors. If you take a closer look you will find that in some rock holes there are small peaks formed, created by the impact bouncing back. After the collision, the surface of the moon broke into a cave several thousand thousand meters deep, so the material inside the moon began to flow outward, rising higher and higher every day.

By the time of cold weather, a mountain like a mountain was formed. We can see that, if the inside of the moon contains water, the water will be pushed up on the surface by the same movement, the water will be able to lie on those ridges. So we observe, studying the peak of the mountain is likely to find water.

Now it is true that on those mountains, there is the possibility of water. " Moon mineralogical device" also observes a position of a rock hole near the moon equator, called "Brio rock cavity" , about 61,000 meters in diameter, the name of a rock niche named after the house. 17th-century French astronomy.

Until last month, scientists found that water exists under 3 different forms as mentioned above. They are located in the deepest and shady places of the moon, in the soil and in rocks. On the moon, water can be used not only for drinking and irrigation but also for extracting oxygen and hydrogen. Therefore, finding water on the moon is extremely important for future explorers and going to the moon in the near future.
