据新华社报道,我国探月工程三期再入返回飞行器服务舱进入了倾角43.7°、高度200 km、周期127 min的环月圆轨道,继续为嫦娥五号任务开展在轨验证试验。服务舱1月4日飞离地月系统拉格朗日-2点(简称地月L2点),1月11日凌晨到达近月点,实施第一次近月制动;1月12日、13日分别进行了第二次、第三次近月制动。目前,服务舱能源平衡,状态良好,地面测控捕获及时、跟踪稳定,飞行控制和数据接收正常,各项拓展试验顺利开展.
According to the Xinhua News Agency, the lunar orbit of China’s lunar exploration project Phase III reentry and return to the aircraft entered a lunar orbit about 43.7 ° with a height of 200 km and a period of 127 minutes, and continued on-orbit validation tests for the Chang’e-5 mission. The service module departed from the Earth-Moon System Lagrange-2 at January 4 (short for the Earth-Moon L2) on January 4 and reached the nearest point on January 11 in the early morning of January 11 to implement the first braking in recent months. On January 12, On the 13th were the second and third brake in recent months. At present, the service cabin has an energy balance and a good condition. The ground-based monitoring and control system has achieved timely and stable tracking and flight control and data reception. Various development tests have been carried out smoothly.
