In the early morning of December 1712 in Beijing, the chang’e-5 lander, carrying lunar samples, made a semi ballistic jump reentry and landed safely in the predetermined area of Siziwang Banner, Inner Mongolia. < / P > < p > with the successful completion of the lunar “digging” by the chang’e-5 lander and the smooth return home with the “local products” of the moon, the flight control site of the chang’e-5 mission of Beijing space flight control center immediately became a sea of joy, and everyone cheered, hugged and congratulated each other. < / P > < p > after 23 days, chang’e-5 has successfully carried lunar samples back to earth and completed this significant journey in the space. < / P > < p > “chang’e-5 mission is not only the final work, but also the foundation work.” Pei Zhaoyu, spokesman for the chang’e-5 mission and deputy director of the lunar exploration and space engineering center of the National Space Administration, said that the chang’e-5 mission is the main task of the “return” step in the three-step “circle, fall and return” of China’s lunar exploration project, which has successfully achieved the return of lunar surface samples. < p > < p > the lunar exploration project is one of the 16 major national science and technology projects determined in the outline of the national medium and long term science and technology development plan. Since its establishment, the National Space Administration has organized more than 2000 units and hundreds of thousands of scientific and technological workers across the country to work together to tackle key problems, complete six exploration missions with high quality and high efficiency, and achieve “six battles and six victories”. < / P > < p > come back from the moon and walk in a dream. As China’s space system engineering with the highest complexity and the largest technological span, chang’e-5 mission has achieved many major breakthroughs in China’s first lunar surface sampling and packaging, lunar take-off, lunar orbit rendezvous and docking, and re-entry and return with samples. Its successful implementation marks the completion of China’s three-step plan of “circling, landing, and returning” on schedule.
