Impressive stuff, and a mission of significance.

pardon my off topic

Mat 7:3 Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye?
Mat 7:4 Or how can you say to your brother, 'Let me take the speck out of your eye,' when there is the log in your own eye?
Mat 7:5 You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother's eye.

The trajectory of China's Chang'e-4 lunar probe was corrected on Sunday afternoon, the second such maneuver since the vessel blasted off on Saturday towards the Moon.


The task, conducted by several satellite tracking and control stations in China, aims to confirm the latitude and longitude of the probe, check information sent by the probe, and prepare for its third trajectory correction.

"Chang'e-4 has just completed its second trajectory correction, and the third one is designed to ensure Chang'e-4 enters the designated orbit and prepare for its soft landing," Li Peng, assistant engineer at Kashgar Satellite Tracking Station of Xi'an Satellite Control Center (XSCC), told China's national broadcaster CCTV.

The journey of Chang'e-4 to the orbit of the Moon will take two hours less than that of its predecessor, Chang'e-3.

"During the 110-hour Earth-Moon transfer, we will spare no efforts to ensure the precise entry conditions at every time," said Liu Qing, another engineer at Kashgar Satellite Tracking Station.

In the next month, scientists will conduct the third trajectory correction, near-moon braking and other key tasks, which will pave the way for a successful soft landing of the probe on the far side of the Moon.

【近月制动成功!嫦娥四号进入环月轨道】“近月制动轨控开机!”“‘林海’跟踪正常!遥外测数据正常!” 肩负人类首次月球背面探测任务的嫦娥四号探测器于12月8日凌晨发射升空,经历了4天的长途跋涉,终于来到了月球身边。12日16时39分25秒,西安卫星测控中心佳木斯深空站发出指令,嫦娥四号探测器7500N变推力发动机成功点火,356秒后,发动机正常关机。根据实时遥测数据监视判断,嫦娥四号已顺利进入近地点100千米,远地点400千米的环月轨道。(骆成 吴浩)
[Success in lunar orbit injection! Chang'e-4 enters the lunar orbit]
Chang'e-4 which carried the first human far-side lunar exploration mission, was launched in the early morning of December 8th. After four days of travelling, it finally came to the moon. At 16:30:25 on 12th Dec, Xi'an Satellite Telemetry and Control Center Jiamusi Deep Space Station issued an order. The 7500N variable thrust engine of Chang'e-4 was successfully ignited. After 356 seconds, the engine was shut down normally. According to the monitoring and analysis of real-time telemetry data, Chang'e-4 has successfully entered the lunar orbit of 100 km perilune and 400 km apolune. ( Luo Cheng Wu Hao)
