The Shenzhou XIV mission(任务)—China’s ninth manned spaceflight—launched(发射) from the Jiuquan Satellite Launch Center on June 5, 2022.
The three astronauts—Chen Dong, Liu Yang and Cai Xuzhe—are being sent to the Tiangong space station. They will stay there for half a year. This is the second time Chen and Liu have gone into space. The flight of three astronauts is also expected to mark the beginning of a period of ten years. During this period, there will be Chinese people in outer space every day.
As of the spacecraft’s arrival on that day, the Tiangong station consists of three parts—the Tianhe core module(核心舱), the Tianzhou 3 and the Tianzhou 4 cargo(货运) ships.
The three astronauts will work with ground controllers to connect the Wentian and Mengtian space labs with the Tianhe module. And then they use a robotic arm to move the labs to their permanent position. Wentian, the station’s first lab part, will be lifted in July by a Long March 5B rocket from Hainan province, while the second lab Mengtian will be launched by the same rocket model in October. After they are connected with Tiangong, the station will form a T-shaped structure.
During their stay, the astronauts will finish two to three spacewalks and give science classes to students. In the second half of their mission period, the Tianzhou 5 cargo craft and the Shenzhou XV astronauts will arrive at the station. The Shenzhou XIV and XV astronauts will meet inside the Tiangong and work together for a short time before Chen’s team flies back to Earth in December.
China has been making one achievement after another with its space missions that reflects the rapid development of its aerospace area. The surprising achievements China has made in space exploration are expected to attract more young people to devote their talents to the meaningful thing that benefits humankind as a whole.
