Yutu No. 2, which is roaming on the back of the moon, has traveled more than 285 meters and observes the lunar environment while walking. One of the latest discoveries is the encounter of a 3m diameter crater that blocks the way the Yutu No. 2 is going, because there are some incredible things that are worth stopping to study. Yutu No. 2 found a mysterious gel-like substance in the crater. It can be seen that these materials have a glassy appearance, which reflects the luster of broken glass and also shows some green color.
However, this green image has been proven to be a reflected light on an obstacle-obstacle camera and has nothing to do with the target. Scientists focus on these gels with metallic luster, but not necessarily metals. The object is correctly said to be a gelatinous substance, which was formed in an ancient age of at least 3 billion years. Yutu No. 2 is cautiously approaching the crater and analyzing the sample. Because we know that any one of the moon's potholes may cause the Yutu No. 2 to fall into it. NASA's Opportunity is that the wheels are caught in a state of inability to move and are abandoned.
The obstacle-obscuring cameras, visible light and near-infrared spectrometers have all been activated to analyze the gelatinous material in the small pit. Because the Yushu No. 2 VNIS instrument has a small field of view, it is very close to the target, which increases the risk of falling into it. From the current survey, these materials are very similar to the 70019 samples discovered by the Apollo 17 astronauts, when geologist Harrison Schmidt collected a similar gelatinous substance from a 3 m diameter crater. The Apollo astronauts were puzzled by this.
After the samples were sent back to Earth, NASA scientists believed that there were dark breccia fragments and black-gloss glassy materials that formed during high-temperature, high-speed impact. This shows that the landing point of the No. 4 has suffered a big impact, forming a glassy crystalline material, at least 3 billion years ago. In other words, the location of Yutu No. 2 has been calm for more than three billion years, until we humans arrive.
