Carbon on the moon questioned the theory of its formation

Scientists recorded the emissions of carbon ions from the surface of the moon. This discovery not only refutes the version of the low content of volatile substances in the bowels of the satellite, but also forcing astronomers to reconsider the model of the formation of the satellite. An article describing the results of a study published in Science Advances.

Since, in the framework of the program “Apollo” spacecraft brought back to Earth samples of lunar soil, the researchers believed that the carbon stocks and other volatile substances on the satellite of our planet severely depleted. This was one of the main foundations of the hypothesis that the Moon was born as a result of a powerful collision between a body the size of Mars, and young Earth, which visible part of the volatile substances evaporate under high temperatures. However, the concept of “dry” moon over time has been questioned, since the analysis of the basalt showed that there are molecules of water, carbon dioxide, fluorine, chlorine, and sulfur. Now scientists have shown that the surface of the satellite also is the flow of carbon ions.

Shoichiro Yokota (Yokota Shoichiro) of Osaka University, together with colleagues analyzed data from satellite “Kaguya”, which was launched in 2007 and conducted in lunar orbit and a half years. On Board the spacecraft was installed on the mass spectrometer, which recorded the emission of ions of different elements, including carbon. It turned out that the surface of the satellite comes visible the flow of ions of carbon, and its capacity differs depending on the area — for example, in the field of younger basalt plains he is stronger than old hills. This suggests that the stocks of the substance are contained somewhere in the mantle.
