After 565 days in space, they will finally be reunited with their families! On 30 April, the Shenzhou-17 manned astronaut crew will return safely to the earth and greet the triumphant return of this heroic space pioneer together with hundreds of millions of space station boosters. Let's feel the hardships and excitement of this space journey through the lens of words, and set our eyes on the farther interstellar gate!

How did astronauts survive the long journey to space?
Yu Kangyi misses the mountains and rivers of his hometown very much, he recalled: "Looking at the vast universe outside the window, the 'round blue dot' in the vast sea of stars, I suddenly remembered the mountains of the motherland, the lakes and towns embedded in it, and the general secretary's speech of 'the motherland is the precious plum blossom', which made me feel extremely homesick and excited to serve the motherland's aerospace dream." "

The nostalgia is like a bright spark, warming the hearts of the astronauts and illuminating the route of their spiritual course. Manned spaceflight is only a small step in the frontier of science and technology, but the significance is a big step in human space exploration.

Captain Hong Feng, who has been forged by aerospace training, has also moved his heart in space drifting. "We are diligently pursuing space exploration and the motherland's aerospace industry, but as human beings, we will inevitably miss our homeland!" It's just that when the green grass overflows in front of the window of the small courtyard, there are endless opportunities and challenges waiting for him in this small period of space rest.

With their steadfast intentions, they have overcome countless influences from extreme environments. The altitude difference of nearly 1,000 kilometers from the ground has created 26 days and nights every day; Super radiation brings hidden dangers to man-machine equipment; Daily high-intensity physical activity also produces serious problems with oxygen and energy supply...... This is more difficult than the other, and it has formed a great test of the astronauts' spiritual strength.

"I've been drowning in a lot of tension all day. When it comes to preparing for return, the intense weightlessness makes it impossible to walk and determine the bearing. That's when I have to do everything I can to control myself and prevent accidents from happening. Gu Wenxing introduced the difficult return voyage, which was only a point-and-go end, and its hardships were unimaginable to the outside world.
How can the aerospace dream be dispelled and passed on little by little?
Any yearning and pursuit requires a relay process, and every astronaut is a hand in hand relay person. At present, the Shen-17 astronaut crew has successfully completed about five months of active space residency, contributing to the country's further building into a space power.
As the vanguard of space exploration, before returning, they successively handed over the two astronaut crews of Shenzhou 16 and Shenzhou 18, guiding the new members with their own personal experience to ensure the efficient inheritance of key technical links such as orbital rendezvous and docking.
"We have jointly completed the first in-orbit assembly rendezvous and docking of China's space station, which is something that each of our astronauts is very proud of!" Looking back on the inheritance of the aerospace dream, Gu Wenxing said that he was very excited.
At the same time, the Shenzhou-17 astronaut crew also carried out a number of tasks such as extravehicular operations, application payload operation, and space station system upgrade and maintenance, which was the icing on the cake for China's aerospace industry. But behind these brilliant achievements is a process of exploration rooted in enthusiasm and experience.
"In the past, everyone was confused about the lack of practical experience in extravehicular repair and maintenance work. However, we learned from the valuable experience of our predecessors, and were not afraid of difficulties, arrogance or impatience, so that we finally successfully completed the extravehicular operation task," Yu Kangyi solved the confusion that had always existed in his heart.
The route of the Shenzhou journey has been laid out from generation to generation by such solidarity and mutual assistance and experience inheritance, and the aerospace pioneers who have gone forward and succeeded have turned their hard work into a channel to the vast universe, injecting inexhaustible impetus into the future of the aerospace industry.
A new chapter, what can be expected on the aerospace stage?
The return of the Shenzhou-17 astronauts also marks a new stage in China's manned space industry. During the "14th Five-Year Plan" period, China's aerospace projects climaxed one after another, with Tiangong, Chang'e, Tianzhou, and Tianlian ...... Wave after wave of unevenness, the majestic bearing standing in the world's aerospace field has become more prominent. Nowadays, the "space-ground integration" network system continues to be built, which is expected to fully release aerospace energy in the fields of space Internet and aerospace big data. Astronauts will take off again based on a higher starting point, and open a new mode and new track together with human-computer interactive unmanned spacecraft. At the same time, the manned lunar landing project is expected to be implemented this cycle, and the map of international commercial space cooperation is gradually being drawn, and China's aerospace industry is embarking on a new journey full of opportunities.
Every journey in space is a magnificent test to cross the sea of stars and touch the starry sky, and it will also be engraved in the annals of the motherland's aerospace history. Let us encourage the astronauts of Shenzhou-17 to go further and further on the journey of space, and work with the motherland to write the grand dream of human beings that will never stop!
