Two GECAM science satellites launched
10 December 2020
Two satellites for the detection of gravitational waves are launched by a Long March-11 carrier rocket from the Xichang Satellite Launch Centre in southwest China's Sichuan Province on 10 December 2020 at 4:14 BJT. Both satellites are for the detection of gravitational waves, composing the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission. The GECAM satellites will be used to monitor high-energy celestial phenomena such as gravitational wave gamma-ray bursts, high-energy radiation of fast radio bursts, special gamma-ray bursts and magnetar bursts, and to study neutron stars, black holes and other compact objects and their merger processes.

Chang'e 5 prepares for journey home
12 December 2020
After 6 days in circular lunar orbit, the Chang'e 5 return capsule raised its orbit into an elliptical path. This orbital maneuver at 9:54 BJT on 12 December prepared the spacecraft for the 2nd manoeuvre to higher the ellipse again and make it consequently possible for the craft to enter a Moon-Earth transfer trajectory and bring the 2 kg of lunar samples home.

Chang'e 5 - Coming Home Again
13 December 2020
At 9:51 BJT, the Chang'e 5 orbiter-re-entry capsule combination carried out its 2nd Moon-Earth transfer injection manoeuvre. Chang'e 5 was at 230 km distance from the Moon's surface when the four 150 N engines of the orbiter fired for 22 minutes. According to real-time monitoring data, the orbiter-returner combination entered the targeted return trajectory successfully. The spacecraft will conduct further flight path adjustments before separating the return capsule which will undergo skip re-entry and subsequent parachute landing.
