Chinanews.com, Beijing, November 29 (Lv Binghong, Kou Ruiqiang, Guo Chaokai) "Brake orbit control starts in recent months!" "'Linhai' tracking is normal! Telemetry data is normal!"

　　At 20:58 on November 28, the Jiamusi Deep Space Station of the Xi’an Satellite Measurement and Control Center successfully placed a remote control command from the Beijing Aerospace Flight Control Center. The engine of the Chang'e-5 probe was successfully ignited and the engine shut down normally after about 17 minutes.

According to real-time telemetry data monitoring and judgment, the Chang'e-5 probe successfully entered an elliptical orbit around the moon, and the first near-moon braking was a complete success.

The Chang'e-5 detector is currently operating normally.

　　In the past few days, the eastern part of Heilongjiang Province has suffered heavy snowfall, and the severe weather conditions have undoubtedly brought a severe test to the "Linhai Shepherd".

"After the blizzard weather, we quickly activated the emergency plan, organized personnel to carry out communication line inspections and snow removal to ensure that the test equipment can be put into the task normally." said Han Lei, the station director of the Jiamusi deep space station.

　　At the same time, the Kashgar Deep Space Station of the Xi'an Satellite Measurement and Control Center, located in the depths of the Gobi, is simultaneously receiving the detector's telemetry and data transmission data.

During the interview, Yang Yantao, head of the Kashgar Deep Space Station, told reporters that the Chang'e-5 mission has many flight stages, many important nodes, many detector components, frequent attitude changes, complex information transmission relationships, very tight switching times, and high mission requirements. Unprecedented.

To this end, the three sets of deep space measurement and control equipment at the Kashgar Deep Space Station will be put into a single task at the same time for the first time to ensure that they can complete multi-target tracking, measurement and control under different measurement and control modes.

　　As an important system to support the implementation of the Chang'e 5 mission, the deep space measurement and control network consisting of the Xi’an Satellite Measurement and Control Center Jiamusi Deep Space Station, Kashgar Deep Space Station, Argentina Deep Space Station, Qingdao Measurement and Control Station and other measurement and control stations will continue to receive and record detectors Remote measurement and data transmission, the implementation of orbit measurement, uplink remote control, and the collection, recording and transmission of interferometric raw data, provide strong measurement and control support for Chang'e-5.

　　In the subsequent full mission phase, the deep space measurement and control network will continue to receive and record the remote measurement and data transmission data of the detector, implement the uplink remote control, orbit measurement, and the collection, recording and transmission of the raw data of the interferometric measurement, so as to guarantee the full journey of Chang'e 5 to the moon. .

　　At the same time, on the Qinghai-Tibet Plateau and Inner Mongolia grasslands, the first and third activity monitoring and control stations are rigorously organizing mission drills. In order to accurately predict the location of the returner and accurately guide the search and rescue units to quickly implement the recovery, they have successively organized thousands of miles of transfers, equipment deployment, and joint testing. At present, the "Star Chasing Caravan" has completed its mission preparations and is always ready to wait for the "Chang'e" to be fully loaded with triumph. (Finish)
