On the journey of the sea of stars, the Shenzhou 17 astronaut crew once again wrote a brilliant stroke.
On March 2, 2024, Beijing time, Tang Hongbo, Tang Shengjie, and Jiang Xinlin, three space warriors, completed an 8-hour spacewalk, which not only demonstrated the courage of human beings to explore the unknown, but also achieved a major breakthrough in China's aerospace history - the maintenance of the first in-orbit spacecraft extravehicular facility.
Today, we should not only praise the technical achievements of this mission, but also delve into the unknown science and art behind it. The solar wings, the energy source of the space station, face countless challenges in the space environment, from tiny particle impacts to extreme temperature changes. Every successful repair is an ultimate test of astronaut skills, psychology and teamwork.
This out-of-cabin activity is not only the application of known technologies, but also a practical exercise for future deep space exploration. In the distant future, when humans set foot on Mars or other planets, this in-orbit repair capability will become crucial. Every step of the way today is paving the way for the future journey of the universe.
And all of this is inseparable from the precise calculation and support of the ground team. Space missions have never been a one-man stage, but a symphony of human wisdom and courage. During this mission, we have seen the rapid progress of China's aerospace science and technology, and we have also felt the endless spirit of human exploration.
In the future, with the deepening of the Shenzhou-17 mission, we will witness more scientific experiments and technical experiments. Every breakthrough is a deep understanding of the unknown world, and every attempt is expanding the boundaries of human activities.
I am convinced that these seemingly distant space explorations will ultimately benefit each and every one of us.
Because every advance in science brings us one step closer to understanding the mysteries of the universe and to our dream of creating a better world.
