嫦娥三号成功实施月面软着陆
China's first moon rover, Yutu, or Jade Rabbit, separated from the lander early on Sunday, several hours after the Chang'e-3 probe soft-landed on the lunar surface.The 140 kg six-wheeled rover touched the lunar surface at 4:35 a.m., leaving deep trace on the loose lunar soil. The process was recorded by the camera on the lander and the images were sent to the earth, according to the Beijing Aerospace Control Center. [i=s] 本帖最后由 sxt0000001 于 2013-12-16 21:13 编辑 [/i]
After the separation, the rover and lander will take photos of each other and start their own scientific explorations.
Engineers made final checks of the environment of the landing site, the situation of the probe and the solar incidence angle late night on Saturday and sent signals of separation to Chang'e-3.
Yutu, atop the probe, extended its solar panel and started to drive slowly to the transfer mechanism at 3:10.
The transfer mechanism unlocked at 4:06 with one side reaching the moon's surface, allowing the rover to descend to the surface following a ladder mechanism.
12月14日21时11分， 嫦娥三号探测器成功落月，中国探测器首次登上地外天体，这标志着我国已成为世界上第三个实现月球软着陆的国家。
落月是从15公里高度开始的。大约11分钟的落月过程中，嫦娥三号依靠自主控制，经过了主减速段、快速调整段、接近段、悬停段、避障段、缓速下降段6个阶段，相对速度从每秒1.7公里逐渐减为0。在距离月面100米高度时，探测器暂时停下脚步，利用敏感器对着陆区进行观测，以避开障碍物、选择着陆点。
