On April 16, after the successful landing of the Shenzhou 13 manned spacecraft return module at the Dongfeng landing field, astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu were safely and smoothly discharged from the capsule and were in good physical condition.
"01 Feel good!" "02 Feel good!" "03 Feel good!" , safe landing, feeling good, gathering a thousand words - is another crystallization of the dream of spaceflight, is the feeling of safe return, is the excitement and pride of exploring the universe, all emotions can be released because of "feeling good", all expressions are in the unspoken because of "feeling good".

From October 15, 2021, When Zhai Zhigang, Wang Yaping, and Ye Guangfu set out to visit Tianhe (part of the Tiangong of the Chinese space station), to April 16, 2022, when the three astronauts successfully returned to Earth. In half a year, the space travel trio has brought us too many surprises and emotions.
The successful launch of Shenzhou 13 has calmed the hearts of countless people; the Shenzhou 13 crew has successfully left the capsule for the first time, and Wang Yaping has taken the first step in the Chinese women's extravehicular spacewalk; the Tiangong Classroom has fascinated countless children for space; the lunar calendar Chinese New Year's Eve, and the trip trio has sent New Year blessings in space, and Chinese spent the New Year in space for the first time... At every important node of Shenzhou 13, we witnessed and paid attention to it, and Wang Yaping said to his daughter: "The mother who picked the stars has returned." At that moment, I don't know how many people wanted to say to Wang Yaping and her colleagues: "Heroes who pick stars, hard work." ”

The smooth return of Shenzhou 13 is of great significance to China's manned spaceflight project. In 1992, the CPC Central Committee made a "three-step" development strategy for the implementation of manned space flight projects, that is, the first step was to launch manned spacecraft, build a preliminary supporting experimental manned spacecraft project, and carry out space application experiments; the second step was to break through the technology of astronaut out-of-the-cabin activities and the rendezvous and docking technology of space vehicles, and launch space laboratories to solve the problem of short-term manned space applications with a certain scale; and the third step was to build a space station to solve the problem of space applications with long-term manned care on a relatively large scale.
According to Berlin Hou, deputy chief designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group, 2022 is of great significance to the entire Chinese space station project, and it is planned to complete the assembly and construction of the space station in orbit through 6 launch missions to achieve the three-step strategic goal of manned space project. The space station mission planning consists of three phases: the key technology verification phase, the construction phase and the operation phase. It is expected that after the Shenzhou 13 astronauts return with a group of 6 months, a comprehensive assessment of the entire key technical verification phase of the space station will be carried out, and then it will be transferred to the construction stage.
According to the "Blue Book of China's Aerospace Science and Technology Activities (2021)", in 2022, China's aerospace will continue to open the "super mode", followed by the launch of the Shenzhou 14 Shenzhou 15 manned spacecraft, the Qingtian Experimental Module I., the Dream Experiment Module II., etc., and the space station will be fully completed this year. That is to say, the smooth return of Zhai Zhigang, Wang Yaping and Ye Guangfu will provide key information to achieve this goal.

Looking back at the history of China's aerospace industry, when China's first manned spacecraft, Shenzhou 5, successfully returned in 2003, "Shenzhou" and the space dream were deeply rooted in the hearts of countless audiences who sat in front of the TV set at that time to watch the return of "Shenzhou 5". 19 years later, the "Shenzhou" series is about to come to the 15th, and the list of astronauts has gradually been lengthened - Yang Liwei, Fei Junlong, Nie Haisheng, Jing Haipeng, Liu Yang, Wang Yaping... Step by step, China's aerospace industry has stepped into the reality of realizing the great dream of manned spaceflight. Ask the sky, dream day, they are spacecraft, but also space dreams.
The journey of Shenzhou 13 not only has a major breakthrough in scientific exploration, but also has great significance in scientific education. In the two Tiangong classes, the water-oil separation experiment showed that there is no natural stratification of water and oil in the space station state; the liquid bridge demonstration experiment showed that in a microgravity environment, water connects two plastic plates; the space parabola experiment demonstrated the different trajectories of the parabola between space and the earth... The experiment seems to be a small science popularization, but it will surely stimulate the curiosity of countless children, stimulate them to explore, to ask questions, to experiment, and to sow seeds for the development of future scientific careers.
Shenzhou 13 successfully landed, astronauts feel good, this is the continuation of the space dream, congratulations to China's spaceflight, look forward to China's spaceflight!
