How much is left of Chand Jai?

Moon rocks are mainly composed of iron and magnesium. The oceans that exist (oceans in the name, not water at all), were formed by volcanic eruptions billions of years ago. We must not forget that in the primitive state all the planets were filled with molten material and the temperature was extremely high. The eruption was therefore nothing unusual. Moon craters are up to 70 km deep. Analyzing the samples collected from the moon, it has been found that oxygen, silicon, iron, magnesium, potassium, calcium, phosphorus, aluminum, chromium, titanium, manganese etc. have been absorbed in the soil of the moon surface. In some places, the radioactive element thorium is abundant, uranium also exists there.

It is necessary to remember that all the basic substances in the universe are formed in stars. Planets or satellites are incapable of producing basic elements. Even the material that the living world is made of, also came from some star. From that point of view, we are all part of the stars.

The elements in the moon also come from some star. Most came from the sun. Because there is no atmosphere and water flow, the original environment of the moon has not changed much, there has been no erosion, the weather has not changed, and the composite material has not been formed much. Since the earth, moon and other planetary satellites are formed in almost the same process, it is expected that proper research on the environment and elements of the moon will also reveal the primitive state and evolution process of the earth and solar system.

At the south pole of the moon, water is frozen, that is, ice. Although it is not on the lunar surface, but rather deep, it was discovered in 2018. Since then, various countries including the United States, Russia, China, European Space Agency, Japan, and India have started efforts to send spacecraft to the South Pole of the Moon.

In the 1960s, US and Soviet spacecraft landed close to the Moon's equator, far from the polar regions (the equator is an imaginary line that divides a planet or satellite into two equal halves, the northern hemisphere and the southern hemisphere).

In August last year, India's Chandrayaan-3 successfully landed 600 km from the south pole of the Moon and conducted some experiments. This is the first polar landing of any spacecraft. The lander of this spacecraft is named Vikram. From there, instead of humans, a small rover named Pragyan was landed on the lunar surface. Little by little, Pragyan also dug up the soil of the south pole area of ​​the moon and sent a strange information. At that time the temperature of the lunar surface was 50 degrees Celsius, while the temperature just 3 inches deep in the soil was only minus 10 degrees Celsius. That is, during the day, when the lunar surface is quite warm, it is freezing cold just below the ground!
