China's first moon rover (月球车), Yutu, set off from the lander early on December 15, several hours after the Chang'e-3 probe (探测器) soft-landed on the moon surface.
The 140 kg six-wheeled rover touched the moon surface at 4:35 a.m., leaving deep lines on the loose moon land. This was recorded by the camera on the lander and the images were sent to the earth, according to the Beijing Aerospace Control Center. After that, the rover and lander will take photos of each other and start their own science explorations.
Earlier this morning, engineers made final checks of the environment of the landing area and the situation of the probe. Yutu, reached its solar panel (光板) and started to drive slowly to the moon at 3:10 a.m.. It took Yutu nearly a whole hour to complete the simple task.
Chang'e-3 landed at the Bay of Rainbows on the moon, at 9:11 p.m. on December 14, making China the
third country in the world to carry out such a mission (执行此类任务) after the United States and Russia.
In old Chinese tales, Yutu was the white pet rabbit of Chang'e’s. The name for the rover was selected following an online survey that collected several million votes from people around the world.
The rover, 1.5 meters long with its two wings folded (折叠), 1 m in width and 1.1 m in height, is a perfect robot controlled by the command center from the earth. It will face challenges including temperature differences of more than 300℃ on the moon.
Yutu will do some research and look for natural resources (资源) for three months, while the lander will conduct an exploration at the landing place for one year. Then they will have a good rest on the moon and will not be used for a long time until China’s next probe visits the moon again.
