The latest news on the 4th: At 8:55 today, the No. 4 detector successfully implemented the orbital control in the orbit around the moon and successfully entered the scheduled lunar preparation track on the back of the moon.

At 4:55, the technicians injected the attitude and orbit parameters into the No. 4 detector at the Beijing Aerospace Flight Control Center. At 8:54, the engine of the No. 4 detector was successfully ignited and the orbit control was started. At 8:56, the real-time telemetry data of the ground monitoring station was monitored and judged. The No. 4 detector has successfully implemented the derailment control from the lunar orbit with an average height of about 100 km from the lunar surface, and entered the near-month point height of about 15 km and far. The lunar orbit with a height of about 100 kilometers per month.

Since December 12, the No. 4 detector successfully implemented the braking of the moon into the orbit of the moon, and carried out two orbital orbit corrections, and carried out four times with the "Bridge Bridge" relay star. Following the link test, the on-orbit test of navigation sensors such as laser ranging, three-dimensional imaging, and microwave ranging speed measurement was carried out, and the detector was prepared to enter the predetermined landing zone and take the opportunity to implement a soft landing on the back of the moon.

The 4th lunar lander and patrol (moon car) was launched at the Xichang Satellite Launch Center at 2:23 am on December 8th, using the Long March 3B modified launch vehicle.

嫦娥4 carries the scientific payloads of China and the Netherlands, Germany, Sweden, Saudi Arabia, etc., and will conduct a land-based patrol inspection on the back Antarctic Atequin Basin on the Moon, realizing the first soft landing on the back of the moon. Inspection survey.
