1 . Having worked in the space station core module Tianhe for three months-the longest-ever human space mission in the Chinese history, three “taikonauts” of the Shenzhou-12 crew returned to Earth on Friday, hitting a new milestone in China's space exploration.
China's first self-developed space station, Tiangong, is independently constructed and operated by the country, demonstrating the country's breakthroughs in technologies concerning the astronauts' long-term stay and health care, recycling and life support system, supply of space materials and operations, as well as in-orbit maintenance.
As scheduled, the Tianzhou-3 cargo craft and the Shenzhou-13 manned spaceship will also be launched later this year todockwith the Tianhe module, and another trio of astronauts will stay in orbit for six months. For 2022, China is considering over a blitz of space missions, including the launch of the Wentian and Mengtian lab modules, two cargo spacecraft and two crewed spaceships, for the building of Tiangong, which is planned to be completed next year.
The two decades saw China launch seven manned spacecraft, two cargo spacecraft, Tiangong-1 experimental space lab and Tiangong-2 space lab, and send 12 astronauts into space, with the first “two steps” achieved, and the construction of Tiangong will mark a new peak of China's space technology.
The China Manned Space Agency has worked with the United Nations Office for Outer Space Affairs to invite UN members for scientific experiments aboard the Tiangong station. As the U.S. National Aeronautics and Space Administration(NASA)chief scientist for human exploration and operations Julie Robinson put it, “Increased scientific access to space is of scientific benefit globally, no matter who builds and operates platforms.”
There is no limit for the vast universe, nor for humanity's exploration endeavors. Tiangong, as a new outpost(前哨)in space and a platform for cooperation, will be China's gift and contribution to all humankind.
