The first rover on the landing page may have discovered the first samples of the lunar mantle, released from the lunar interior by a giant, ancient cosmic impression, a new exploration find.
These findings suggest the rover, China's Yutu-2, may one day help to solve the mystery and evolve .
Earlier studies suggested that, like the rest of the solar system's inner stone bodies the moon was covered with a sea of magma up to hundreds of deep depths as it was newly formed and still warm from its creation. As this magma ocean cooled and solidified, denser minerals rich in iron and magnesium, such as olivine, would have crystallized at its base, while lighter minerals rich in silicon and aluminum, such as plagioclase, would have flown to the surface, potentially explain why large parts of the moon crust are now 98 percent plagioclase.

This ruling model of the moon's formation and development is, however, discussed hotly. This is because it remains uncertain whether the moon's magma sea had the right mix of chemical and physical properties for its minerals to separate as the model suggests they did.
One way to help solve the mystery of the moon's earliest days is to analyze its mantle ̵
Instead of launching probes to drill in the moon to retrieve moon cable samples, scientists have long proposed to leave cosmic The impact on the moon makes the dirty work of digging, the study researchers said. For example, on the other side of the moon, a huge, old collision excavated a 1,550-kilometer (2,500-kilometer) crater known as the South Pole-Aitken basin.
"Very Large Craters – For example, South Pole-Aitken Basin – can potentially penetrate crust and test the lunar mantle," co-author Bin Liu, a planet scientist at the Key Laboratory of Lunar and Deep Space Exploration in Beijing, Space said. com.
Using the Yutu-2 rover, Chinese scientists have revealed what may be the first details of the moon cap.
In January, Chang & # 4 introduced 4 lands Yutu-2 ] on the relatively smooth 115 km wide (186 km) floor of the Von Kármán crater in the South Pole-Aitken basin. The rover discovered minerals that were markedly different from the typical moon surface material suggested by the scientists, likely to be excavated under the south pole-Aitken Basin floor by the effect that created the nearby 45 km long (72 km) Finsen crater. 19659002] Analysis of the wavelengths of light reflected from these minerals revealed the presence of olivine and low-calcium pyroxene. This matches long-lasting predictions about the composition of the upper moon cape and can support the predominant model of monthly formation and evolution with a refrigerated seaweed that scientists noted.
"The ultimate goal is to decipher the mystery of lunar composition," Liu said.
The researchers performed their results in the May 16 issue of the journal Nature.
