According to China’s space WeChat official account, the changer five orbiter and return assembly were successfully separated from the riser at 12:35 on December 6th, and entered the waiting phase of the ring moon, and were ready to return to earth by chance.
At 5:42 today, the chang’e-5 lander successfully rendezvous and dock with the orbiter and returner assembly, and safely transferred the sample container to the returner at 6:12.
According to the previous news on the official website of Aerospace Science and technology group, the chang’e-5 mission will last 23 days and collect about 2 kg of lunar rock and soil samples to return to earth. It has been 12 days since the launch in the early morning of November 24, and it is more than half the time.
According to the plan, after the completion of the lunar surface work, the chang’e-5 lander will finally land in Siziwang Banner, Inner Mongolia, after going through the flight stages of lunar surface rise, lunar orbit rendezvous and docking, sample transfer, lunar orbit waiting, lunar ground transfer and reentry return.
At 4:30 on November 24, China successfully launched the chang’e-5 probe of the lunar exploration project with the long March-5 remote-5 carrier rocket at China’s Wenchang space launch site. After about 2200 seconds of flight, the rocket successfully put the probe into the predetermined orbit, starting China’s first return journey of sampling extraterrestrial objects.
Chang’e-5 mission plans to achieve three major engineering objectives: first, to break through the key technologies of narrow window multi orbit binding launch, automatic lunar surface sampling and packaging, lunar surface take-off, lunar orbit rendezvous and docking, and lunar sample storage, so as to improve China’s aerospace technology level; The second is to realize the automatic sampling and return of extraterrestrial objects for the first time in China, and promote the great progress of science and technology in China; Third, improve the lunar exploration engineering system to accumulate important talents, technology and material foundation for China’s future manned lunar landing and deep space exploration.
The reporter learned from the National Space Administration that at 6:59 on December 8, the chang’e-5 ascent was controlled to leave orbit according to the ground instructions, and landed at the predetermined landing point near 0 degrees longitude and 30 degrees south latitude of the lunar surface at about 7:30.
Previously, the chang’e-5 lander took off for the first time in China, rendezvous and docking with the orbital reentry assembly in the predetermined orbit, completed the transfer of lunar samples, and successfully separated from the orbital reentry assembly at about 12:00 on December 6.
Experts from the lunar exploration and space engineering center of the National Space Administration said that the chang’e-5 ascent has successfully completed its mission, and the controlled off orbit landing on the moon can prevent it from becoming space garbage and affecting the follow-up lunar exploration missions of the international community. This is an important commitment of China, as a responsible power, to the peaceful exploration and utilization of space by mankind.
