Moon Rover robotic arm put in a successful test

China News Agency, Beijing, December 23 (open Ouyang Yu Qi Dengfeng), December 23, at the Beijing Aerospace command and control center under the control and precision of the detector system in collaboration with, "the rabbit" Rovers stretched, "rabbit's hand", has successfully completed the picker Lunar placement test.

Beijing Aerospace command and control center, Deputy Director General Wu Fenglei said, the entire testing process to complete the mechanical arm, wrist and shoulder joints, movement in the opposite direction. Most people's arms to complete these actions only for a few seconds, and work placement test today, "the rabbit" spent tens of minutes.

Allegedly, the whole arm to put and placement test is divided into two steps-gathering, just like the bent arm telescopic, and the difficulty is very high.

Flight control center in Beijing's chief engineer said Zhou Jianliang, arm placement test is "rabbit," lunar month test phase a key job. Current placement test is to start in the first night, before to "rabbit" to the best State for effective upon completion of the Moonlight over a large number of scientific exploration tasks.

On the surface, "rabbit," outside the car in addition to a complete scientific explorations of the Moon Mission, also had to withstand months, afternoon and night test of the two extreme environments. Is month by month afternoon sun shining strongly, in the month afternoon stage, lunar surface temperatures up to more than 100 degrees, for the preservation of scientific instruments, "the rabbit" to "lunch break". Moonlight on the contrary, after entering the moon does not have any exposure to the Sun, lunar surface temperature will drop to below zero more than 180 degrees, the "rabbit" was worthy of the cold nights.

According to the Beijing control center experts, the Moonlight will come around 26th this month, about half a month in duration. When the "rabbit," Rovers receive no energy complement, will go into hibernation until the Lunar sunny again. (End text)

　　中新社北京12月23日电 (欧阳开宇 祁登峰)12月23日凌晨5时许，在北京航天飞行控制中心和探测器系统的精密协同控制下，“玉兔”号月球车舒展“玉兔之手”，顺利完成了机械臂月面投放测试工作。

　　北京航天飞行控制中心总体室副主任吴风雷介绍说，整个测试过程要完成机械臂腕部和肩部关节的正、反方向运动。一般人的手臂完成这些动作仅需几秒钟，而今天的投放测试工作，“玉兔”却花了几十分钟。

　　据称，整个机械臂投放测试工作分为投放和收拢两个步骤，就像人的手臂伸缩弯曲一样，而难度却非常高。

　　北京飞控中心总工程师周建亮说，机械臂投放测试是“玉兔号”月球车月面测试阶段的一项关键工作。目前进行投放测试是为了在第一个月夜来临之前，把“玉兔”调整到最佳状态，以有效完成月夜结束后大量的科学探测任务。

　　在月面上，“玉兔号”月球车除了完成科学探测任务外，还必须经受住月午和月夜两个极端恶劣环境的考验。月午是月面受太阳光照射比较强烈的时间，在月午阶段，月面温度高达100多度，为保护科学仪器，“玉兔”要“午休”。而月夜恰恰相反，进入月夜后没有任何太阳光照射，月面温度将降低到零下180多度，这对“玉兔”来说是名副其实的寒夜。

　　据北京飞控中心专家介绍，此次月夜将于本月26日左右来临，持续时间约半个月。届时“玉兔号”月球车得不到任何能量补充，将进入休眠状态，直至月面再次阳光普照。(完)
