Chinese rover discovers new type of moon rock

As the country continues to harness its newfound wealth and power to take on more space projects, its only a matter time before we see it on an equal footing as Russian Federation. Since then, we’ve continued to study the Moon’s surface from afar, using remote orbiters. The find suggests the moon’s make-up is more diverse than previously thought, and will help interpret future satellite-based observations. Detailed results of Chang’e-3 mission team have been reported in the journal Nature Communications.

Researchers said this separation process led to formation of the moon’s mantle and crust. This triggered a period of intense volcanic activity and eruptions that lasted another billion years.

Scientists believe that the moon formed after a collision between a young Earth and a Mars-sized planet, which means that most of the moon is made of the same types of rock that form Earth.

As per Washington University in St. Louis, Missouri, which is among the organizations that analyzed the data that has been received from the mission, the collection of rock samples was done from Chang’e-3’s landing area in the Imbrium basin.

Researchers involved in the Chang’e-3 moon mission, China’s first successful attempt to land a unmanned craft on the moon, unveiled that the volcanic rock samples analyzed by the mission’s rover Yutu were never seen before. Imbrium basin in also considered one of the most prominent impact basins that are visible from Earth.

Essentially, The Guardian explained, minerals in molten rock tend to crystalize at different temperatures, thus the newly found moon rock provides some insight into the deep interior of the moon. As such, the crater offered an opportunity to peer into a later chapter of the Moon’s history.

Scientists had some sense that this young basalt was present in Yutu’s neighborhood even before the rover got there, but this finding is the first direct confirmation of the special rocks. Several aspects of the samples’ mineralogy were unusual.

The titanium ended up in a mineral called ilmenite (FeTiO3) that typically doesn’t crystallize until a very late stage, when perhaps only 5 percent of the original melt remains. Ilmenite is one of the first minerals to cool out of magma due to its low melting point, they noted. Both of these compositions (high and low titanium) were observed by Apollo and Luna. Now peer towards the northernmost edge of that dark circle-that’s where the Yutu rover sits among these basalt rocks, slowly gathering dust. Now, we’re starting to see a gradation in concentration. “We’re still trying to figure out exactly how this happened”.

This variation reflects significant differences in the mantle source regions that derive from the time when the early magma ocean first solidified. The rover has been immobile for some time, though was still sending pings to Earth as late as October of 2015, China’s state-run Xinhua news agency said. But the frequency of impacts after the LBH isn’t well understood. The new discovery suggests that lunar surface (upper mantle) is much less uniform in its composition compared to that on Earth. Yutu, however, observed the olivine was iron-rich, meaning it formed later. “We now have “ground truth” for our remote sensing, a well-characterised sample in a key location”, Jolliff said.
