The moon is our closest cosmopolitan neighbor to us, and is also the only celestial body with human footprints at the present time. We know well that on the surface of the Moon there is no air, no water, but only ice. That’s why scientists were so surprised when they discovered hematite on the Moon: for this iron oxide to form on Earth, two indispensable conditions were needed: air and water.
There is one more horizontal and left point: the Moon is constantly subjected to streams of hydrogen from the solar wind – which can provide a large amount of electrons to matter on the lunar surface. Because oxidation only takes place when iron loses electrons, the condition on “Hang’s house” is too difficult for oxidation to take place, when the solar wind is continuously blowing sideways.
The Indian Space Research Foundation Chandrayaan-1 has obtained data on the existence of hematite on the Moon. In addition, the Moon Mineral Mapping Equipment (M3) designed by NASA has also conducted spectral analysis to find out the composition of the lunar surface.
Using the same methods, planetary scientist Shuai Li and colleagues at the University of Hawaii discovered ice on the Moon in 2018. During this data analysis, Li continued to find a remarkable point. Italy.
“When monitoring the M3’s data as it looked at the polar region, I saw a few spectral traces that showed many differences from samples at low latitudes and samples taken from Apollo missions.“, Professor Li said. “I wonder if there is a reaction between water and rock on the Moon. And after months of research, I discovered that I was looking at the properties of the hematite“.
How was this matter on the Moon?
Data show that hematite is present in areas with traces of water and is involved in meteorite collisions. Scientists believe that the icy water has mixed with the topsoil of the Moon, bounced up and melted when the meteor hit the lunar surface.
Interestingly, the hematite occurs in the part of the Moon facing the Earth. Researcher Li believes that this is evidence supporting the hypothesis that hematite formation is related to the Blue Planet.
Hematite at the poles of the Moon.
“This reminded me of the Kaguya mission discovery made by the Japanese, showing that oxygen from the upper atmosphere could be blown away by the solar wind to the Moon. Therefore, oxygen from the Earth may be responsible for the production of hematite“. Besides, at the full moon, the Earth will block up to 99% of the solar wind reaching the Moon, so there will be time for the hematite to form.
Combining the factors, we see that the Moon can have a small amount of water, a small amount of oxygen from the Earth and can synthesize hematite once a month; This process lasted for several billion years, then the hematite would appear on the Moon.
However, the above factors are only conjecture, we still have not completely explained this mystery. In the dark part of the Moon, where it is impossible to receive the oxygen blown from the Earth due to the solar wind, the probe satellites still detect the existence of hematite.
If you can hold these precious specimens in your hand, and if they still have oxygen molecules of Earth origin, we will both analyze the development of the Earth’s atmosphere and the history of development. rocky soil on the Moon.
Professor Li concluded: “This discovery will change our understanding of the polar regions of the Moon. Earth may have played a key role in the formation of the lunar surface“.
