Moon was not cold and dead as it is today - New Research

Science & Tech A- A A+

The CNSA’s mission Chang’E probe (CE-4) was the first mission to land on the far side of the moon and providing new insights about the dark side of the Moon. Now, the probe has collected new evidence from the largest crater in the solar system, clarifying how the moon may have evolved, Tech Explorist reported.

One core hypothesis posits the moon was not exactly as cold and dead as it is today. Rather it likely began as a giant, molten marble loaded with magma oceans. These oceans gradually cooled, saving substantial minerals, for example, the green-hued olivine or the low-calcium pyroxene deeper into the lunar mantle. Less dense minerals floated to the top in this manner giving the moon a progression of evident land layers like a cosmic onion. The outside layer, the highest layer, is made generally out of aluminum silicate or plagioclase.

“The evolution of the moon may provide a window into the evolution of Earth and other terrestrial planets, because its surface is relatively untouched compared to, say, the early planetary surface of Earth,” Corresponding author LI Chunlai, a professor of the National Astronomical Observatories of Chinese Academy of Sciences (NAOC) said

As these elements are expected much deeper in the mantle, scientists suggest that they were ejected from an impact event caused by a meteor striking the lunar surface. The rover is exploring close to the 72-kilometer Finsen Crater so the minerals may have been sprayed across the surface during that crater’s creation.

CE-4 will need to explore more to better understand the geology of its landing site, as well as collect much more spectral data to validate its initial findings and to fully understand the composition of the lunar mantle.
