For all the jokes that indicate that the moon is made of cheese, scientists have actually tried to understand the composition of the moon mantle, which exists between the crust and the core.
Effect craters are how researchers can learn more about the development of the moon and how it was formed. When asteroids and other objects collide with the moon, the crust is cracked and parts of the mantle reach the surface. Then the Yutu-2 rover looked for some of these pieces. The study describing its findings was published on Wednesday in the journal Nature.
In the 1970s, some astronomers suggested that a magma sea covered the moon's surface early in its history. Magma is the molten material that forms stones. When cooled, the minerals fell at the top, and heavier elements dropped. The top formed a basalt crust over a mantle of minerals. They believed that some of these minerals could be olivine and pyroxine, found in asteroids and the earth's upper mantle.
And learn more about how the moon evolved could also shed light on the evolution of the earth. Compared to the earth, the moon's surface is relatively untouched, the researchers said. ”
"Understanding the composition of the moon mantle is crucial to testing a magma sea ever existed, postulated, "says Li Chunlai, studying authors and professor of the national astronomical observatories of the Chinese Academy of Sciences in a statement. "It also helps to deepen our understanding of the thermal and magmatic evolution of the moon."
Chang # 4 landed in Von Karman crater on January 3. Then it deployed Yutu-2. The rover's purpose was to explore the southern pole-Aitken basin, the oldest and largest crater on the multi-faceted side, which is 1,553 miles across.
Data samples collected by the rover on the ground floor indicated traces of olivine. Samples from deeper effects in the pool showed more olivine. Since basalt contains both, theorists theorized that the mantle could contain olivine and the pyroxene equally, rather than being dominated by one.
The rover will have to explore more of his landing site to understand the composition of the mantle, but the first mission to the multi-faceted side is already gathering important data.
Next, Yutu-2 will try more material from the crater floor to determine its origin, and researchers are looking at the possibility of returning samples to the earth.
