China has become the first country to land a spacecraft on the far side of the moon. The unmanned Chang’e-4 probe (探测器)—the name was inspired by an ancient Chinese moon goddess—touched down last week in the South Pole-Aitken basin. Landing on the moon’s far side is extremely challenging. Because the moon’s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot where it could send signals to the spacecraft and to Earth. The far side of the moon is of particular interest to scientists because it has a lot of deep craters (环形山), more so than the familiar near side. Chinese researchers hope to use the instruments onboard Chang’e-4 to find and study areas of the South Pole-Aitken basin. “This really excites scientists, ” Carle Pieters, a scientist at Brown University, says, “because it means we have the chance to obtain information about how the moon is constructed. ” Data about the moon’s composition, such as how much ice and other treasures it contains, could help China decide whether its plans for a future lunar (月球的) base are practical.
