NASA is looking for water on the moon's surface
Searching for water on the surface of the moon is almost like a contemporary obsession in a number of countries. Besides the United States of America, India, China and Japan are trying to study the composition and quantities of water on the surface of the moon as accurately as possible.
This affects the plans of all those future countries to establish fixed bases on the moon, which has not only scientific but also economic dimensions, as scientists believe that the moon may someday be a source of precious resources. In addition to containing the surface of the moon on the important elements such as oxygen, silicon and ice water, there are also aspirations to extract "helium-3" from the moon, which is a form of helium that could help in developing safer and cheaper images with a wide difference from nuclear reactions, thus saving a tremendous amount of energy annually.
Researchers from the US Aerospace and Space Agency (NASA) have confirmed that the water on the surface of the moon exists in the form that we know on Earth in places exposed to sunlight, not only in dark places, which affects our perceptions of the amount of water on the surface of the moon.
This is not the first time that the presence of water on the surface of the moon has been indicated. Since the Apollo flights in 1969, that suggestion was present and confirmed by the images captured by the "LCROSS" mission, which examines the lunar craters, through the Indian mission "Chandrayaan-1".
But the problem was always to make sure that the image of water that we know existed in nature, "H2O", as it was also possible for the same data that scientists previously monitored to refer to hydroxyl molecules, "HO" (HO). The first direct confirmation that it is the water that we know, and the question of how water was formed on the surface of the moon is still a matter of discussion among researchers in this range, as one hypothesis envisages that it was presented with comets that collide with the surface of the moon, while the other hypothesis is that hydrogen came with the solar wind Then, through a chemical reaction on the surface of the moon, it turned into hydroxyl and then water, and it is believed that more accurate research in the future will reveal this secret.
And the agency announced in an official statement that the researchers used the SOFIA Flying Observatory (SOFIA), which is a "Boeing 747 SB" plane carrying a telescope with a mirror diameter of 2.7 meters. This telescope has an important advantage, which is to get rid of the bad effect of the presence of water vapor in The atmosphere on astronomical data, as that plane rises to the stratosphere, and at some point between 12 and 50 km altitude, a window for the telescope opens and takes pictures in the infrared range, and there the telescope avoids 99% of the atmosphere's steam.
