Report from this newspaper (Reporter Gan Xiao, Correspondent Duan Xun, Ye Yutian) The National Space Administration learned that on November 30, the flight control team of the lunar exploration project Chang’e-5 mission carried out the Chang’e-5 probe landing as planned The combined body of the orbiter and the returner is separated from the combined body of the orbiter and the returner.

At 4:40 in the morning, under the precise control of scientific and technical personnel, the Chang’e-5 detector assembly separated smoothly. Up to now, the detector systems are in good condition, and the ground measurement and control communication is normal. The orbiter and returner assembly will continue to fly on the lunar orbit with an average altitude of about 200 kilometers and wait for the ascender to rendezvous and dock, and the lander and ascender assembly An opportunity will be selected to implement a soft landing on the lunar surface, and follow-up work such as automatic sampling.

The Chang’e-5 probe was successfully launched on the Wenchang Space Launch Site at 4:30 on November 24 with the Long March-5 Yaowu carrier rocket. The rocket flew for about 2,200 seconds and then sent the probe into the intended orbit. , To start our country’s first return journey from the sampling of extraterrestrial objects.

At 22:06 on the 24th, the Chang’e-5 probe completed its first orbit correction. The Chang’e-5 mission launched into orbit with high accuracy and small orbit corrections. At 22:06 on the 25th, the second orbit correction was completed.

At 20:58 on the 28th, the Chang’e-5 probe completed near-moon braking at a distance of about 400 kilometers from the lunar surface, and was captured by the lunar gravity and entered into an orbit around the moon. At 20:23 on the 29th, the second brake was completed, and the “brake” again at the near moon point, changing from an elliptical orbit around the moon to a nearly circular orbit around the moon.
