We all know that there is no presence of oxygen and liquid water on the moon, and then to the moon is rusting? (rust on the moon), It is quite a mystery. We are familiar with the process of rusting. When water and oxygen interact with iron it results in rust. We often see rust on nails and on planet Mars too.

The planet Mars has red color due to iron-rich minerals, in simple words the surface of Mars contains lots of Iron Oxide, this is about Mars. What about Moon?

The data was achieved from the “Chandrayaan – 1” lunar mission. Shuai Li found that the lunar poles had iron-rich rocks. And its spectral signature matched with hematite. Hematite is commonly found on the earth’s surface and it is a specific type of rust. According to the researchers, the hematite is the result of the oxidation of iron on the Moon’s surface due to oxygen from Earth’s upper atmosphere. Moon has iron-rich rocks but there is no presence of oxygen and water. And these are the two important elements to carry out the process of rusting.

Earth constantly faces solar winds and so does the moon, but the earth has its magnetosphere to protect it from the wind. The Moon lacks this protective layer. When Earth faces solar wind the magnetic layer tends to elongate at the opposite side. The tail has a capacity to block 99% of solar radiations which protects the moon when the moon is in full moon phase. This gives enough room to form rust on the Moon.

The tail formed during solar wind tends to carry the oxygen from the upper layer of Earth’s atmosphere. The data from Chandrayaan 1 shows that the poles of the Moon do contain water ice. However, we still need more data to understand the exact reason behind the Moon’s rust.
