　　In the early morning of October 16, under the illumination of more than 100 spotlights, the manned space launch site of the Jiuquan Satellite Launch Center was brightly lit.

In the dark night beyond the lights, there is an endless expanse of land concealed.

　　The sky is wider than the earth.

The galaxy on the autumn night is brilliant, and the brightest group of "stars" is undoubtedly the Chinese Space Station.

　　What is broader than the sky is the mind and dream of human beings. Today, three Chinese astronauts, Zhai Zhigang, Wang Yaping, and Ye Guangfu, took the Shenzhou 13 to expedition to space again, starting China’s longest manned flight so far.

　　This is a courageous exploration, this is an expedition carrying a dream.

　　As the decisive battle and final battle in the verification phase of the Chinese space station's key technologies, and a key battle connecting the past and the future during the orbital construction of the space station, Shenzhou 13 ushered in the era of long-term manned presence on the Chinese space station.

China's manned spaceflight industry has reached another milestone, and the Chinese nation has a new coordinate point in the vast universe.

Love star, love moon, love space

　　Final assembly, testing, transfer, inspection... the launch site is one after another, like a moving movement, advancing layer by layer and constantly agitating.

Finally, this large-scale symphony has entered the most exciting section: the launch is about to begin, and the journey is just around the corner.

　　On the evening of the 15th, in Wentian Pavilion, three astronauts set out here.

　　Ask the Tiange, want to ask the sky?

　　More than 900 years ago, it was also such a clear autumn night. A Chinese poet asked the sky about the wine, imagining that there should be a Qionglou Yuyu on the horizon.

　　Today, the Chinese, who are full of romance and reason, will begin to fly beyond their dreams to the real "Heavenly Palace" built by themselves.

There is the accumulation of the wisdom and blood and sweat of generations of astronauts, and it is the heavenly palace that has made Chinese astronauts and hundreds of millions of people extremely practical and glorious.

　　"Comrade commander-in-chief, we are instructed to carry out the Shenzhou 13 manned flight mission. Preparations are complete, please give instructions!" Zhai Zhigang saluted the report in a white cabin space suit.

　　This is the second time that Zhai Zhigang has led the team as the commander of the "Flying Crew".

In 2008, he completed the first spacewalk of the Chinese.

His footprints were printed on the vast cosmic starry sky, and also on the spiritual starry sky of the Chinese nation.

　　The "space walk" took 19 minutes and 35 seconds, and Zhai Zhigang went on the road to the sky for 13 long years.

During these 13 years, he has served as a backup astronaut for the Shenzhou 10 and Shenzhou 12 missions.

Training day after day, accepting selections again and again, what supported him along the way?

　　He only answered two words: "Love!"

　　Without love, there is no support enough to deliver the tempering of youth and even life.

That is the love of flying, the love of profession, and the love of the aerospace industry of the motherland.

Under the rigorous, meticulous, calm, and calm package, this love is extremely hot.

　　"The five-star red flag flutters in the wind, how loud the victory song..." The familiar song played.

From Shenzhou 5 to Shenzhou 13, every astronaut’s expedition was accompanied by this background music.

There is an immature childlike voice in the singing, from a group of children from the central and western regions-no matter how high the mountain is, it can't stop the wings of dreams.

This "dialogue between youth and starry sky" will surely have an extremely profound response.

　　The children’s eyes are more focused on the female astronaut Wang Yaping. In 2013, this beautiful "female space teacher" gave an extraordinary space lesson to more than 60 million students across the country, which was buried in the hearts of many young people. The seeds of science.

　　On this expedition, Wang Yaping will once again "touch the dream with the eyes of children."

"As long as you have the courage to dream, chase it, and build your own dream spacecraft with wisdom and sweat, you will definitely be able to usher in the launch moment of your dreams and fly to the vast starry sky that belongs to you!" Wang Yaping said to the children before flying.

　　For Ye Guangfu, the astronaut who went to space for the first time, space is the call of dreams, and it is also a severe challenge.

The 6-month flight in orbit, complicated and arduous experiments and test tasks, put forward extremely high requirements for the astronauts' physical and mental quality, knowledge and skills, and emergency response capabilities.

The challenges faced by astronauts are unprecedented.

To this end, they have undergone more than 200 trainings in 8 categories.

　　The heart is in nine days, the road is under your feet, to realize your dreams, you must always struggle step by step. Perhaps only those who have experienced it can experience the sweat and tears.

　　"Learn from the astronauts! Salute the astronauts!" In the audience area, the crowd from all over the world waved the five-star red flag in their hands and shouted rhythmically.

Minority people dressed in costumes and danced cheerfully.

　　At this moment, from the old Huafa to the immature children, everyone's eyes are shining with stars.

Every star may be a surprise in the future.

There is light, dream, hero

　　On October 15, 2003, in front of Wentian Pavilion, the singing of "Singing the Motherland" sounded. Zhai Zhigang and Yang Liwei hugged tightly and sent their comrades to space for the first time.

　　On the same day 18 years later, in the same place and in the same song, two space heroes once again appeared at the expedition ceremony. This time, it was Yang Liwei seeing Zhai Zhigang off.

　　History often uses coincidences to witness achievements.

　　Over the past 18 years, from one person to multiple people for multiple days, from in-vehicle experiments to space walks, from short-term stays to long-term stays... China's manned space project has successively mastered key technologies such as world round trip, space exit, rendezvous and docking, etc. , Steadily advancing into the space station stage.

　　The three astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu started a six-month flight mission.

This is the sixth mission of the space station's key technology verification phase, and it is also the final battle.

When this crew of astronauts composed of one "post-60s" and two "post-80s" returns smoothly, China's manned space project will enter the space station construction phase.

　　Liu Feng, who was still a frontline staff member, has a deep memory of Yang Liwei’s expedition: It was the first manned launch mission of the Long March 2 F rocket. When the elevator door of the astronauts slowly opened, Yang Liwei walked out with a small square box. His eyes are calm and his steps are firm.

　　His eyes touched, Liu Feng's heart trembled, and his eyes moistened.

What kind of belief is it that allows a person to head toward unknown risks without hesitation?

　　Manned space engineering is a high-risk undertaking, but there has never been a shortage of heroes.

Not only the first space expedition back then, but also rendezvous and docking, out-of-cabin activities, crossing black barriers...

　　The six-month long-term space stay puts more stringent requirements on the physical and mental health of the space station, spacecraft, and astronauts.

The physical and mental health of astronauts has been negatively affected for a long time. The weightlessness effect of the musculoskeletal system and cardiovascular system will be more prominent, and problems such as sleep disturbance, fatigue, infection, gastrointestinal disease and cardiovascular dysfunction may occur, and emergency medicine will appear. The probability of problems will also increase.

　　When the Shenzhou 13 spacecraft successfully lifted off, another rocket had been erected in place, and the other spacecraft had also been fully equipped, ready to respond to extreme situations at any time.

　　In fact, the danger is not limited to space.

Except for the astronauts entering space, the scientific research participants in every process and every position are ordinary heroes.

　　China's development of extravehicular space suits with completely independent intellectual property rights also has a danger that ordinary people do not know.

Before the delivery of the extravehicular spacesuit, it needs to be worn by volunteers to perform a low-pressure cabin test, and check its various performance indicators in a simulated outer space state that is almost vacuum.

　　Even with minor mistakes, the lives of volunteers will be seriously threatened.

However, every time a volunteer is recruited from among scientific researchers, someone takes the initiative to sign up.

　　In order to carry out ground and field survival training for astronauts, the instructor team needs to set up various harsh environments in the forest and Gobi, take the road that no one has walked, and explore the risks that others have not explored.

　　There are also inspections, transportation, and refueling of highly toxic and volatile special fuels. Any deflagration or leakage may cost the participants their lives.

　　If there is no Qianqiu Karma in my heart, where will the prosperous world bloom.

Every milestone of China's manned spaceflight project is that every astronaut, with dreams and beliefs, walks toward the light step by step.

　　In order to adhere to the ideals and beliefs of generations of astronauts, the Shenzhou 13 crew entered the Jiuquan Satellite Launch Center. In addition to conducting special training and experiments, activities such as the flag raising ceremony and paying respects to the Dongfeng Martyrs Cemetery were also included in the work manual.

In the Dongfeng Martyrs Cemetery, there are more than 700 ancestors who have devoted themselves to China's aerospace industry.

　　In order to carry the spirit of human spaceflight, the Shenzhou 13 mission planned a series of popular science and public welfare activities. Wang Yaping will once again become "Teacher Wang" and will also combine the opportunities of traditional festivals to promote China's traditional culture.

　　Liu Feng, who watched Yang Liwei's first expedition, appeared in the crowd seeing off the new "space trio."

Now Liu Feng has grown into a rocket deputy chief engineer. He said that his belief and courage have never been lost over the years.

　　When the Shenzhou 13 spacecraft rose into the sky in the night, the hour hand had already pointed to the early morning of October 16.

　　On October 16, 57 years ago, a huge mushroom cloud soared into the sky over the Gobi Desert, and China's first atomic bomb exploded successfully.

Selfless, no regrets, endless

　　"5,4,3,2,1, light up!" At 0:23, the Long March 2 F Yao 13 rocket rose from the ground and went straight into the sky at 0:23.

　　From erection to launch, this rocket has been "standing" for more than 5 months, becoming the rocket with the longest "standing" time in the history of China's aerospace.

　　As the first rocket in China’s space history that integrates emergency rescue and launch missions, since the launch of Shenzhou 12, the Long March 2 F Yao 13 rocket has taken on emergency duty and has been "looking up" at the starry sky until Shenzhou 12 was launched. The 13th spacecraft was sent into space.

　　Looking up at the sky with the Long March 2 F Yao 13 rocket is a Chinese astronaut.

As the exploration of the vast universe accelerates, China will complete 11 intensive missions to build an independently constructed and independently operated space station.

In the meantime, there will be multiple recovery missions and verification of key technologies in orbit.

　　This is a career that will last a lifetime.

Being able to take a full weekend off has become the wish of many participants, but it can only be a wish.

　　From Shenzhou 1 to Shenzhou 13, the final assembly operator Chen Wei was not absent for every launch mission, and was called the "Old Master" by my colleagues.

With Chen Wei there, everyone is at ease.

For more than 20 years, although his home was in Shanghai, Chen Wei was more familiar with Dongfeng Aerospace City in the Gobi Desert, and he was not used to returning to Shanghai.

　　This is a career that must be kept in mind.

If the aiming orbit data deviates by 0.1 degree, the orbit point will deviate by hundreds of kilometers, and the consequences are unimaginable.

For each launch, the aiming personnel were the last group of evacuees until the rocket entered the 15-minute countdown to launch and the state of the rocket had stabilized before boarding the evacuation vehicle.

　　This is also a never-ending business.

In 2011, the Shenzhou-8 spacecraft and the Tiangong-1 target aircraft achieved axial docking. China achieved unmanned space rendezvous and docking for the first time, becoming the third country in the world to independently master space rendezvous and docking technology.

　　On the 10th anniversary of "Space Kiss", China Aerospace ushered in the first radial rendezvous and docking.

From unmanned to manned, from automatic to manual, from a few days to 6.5 hours, from axial docking to radial docking, in the endless journey of exploring the universe, manned space technology continues to make breakthroughs and innovations, but it is always on the way.

　　Resonance, which was once a world-class space launch problem.

During the rocket launch process in the United States, France and other countries, there was a resonance phenomenon that lasted for tens of seconds.

In the article "A Day in Space", China's first astronaut Yang Liwei also recalled the resonance phenomenon during the Shenzhou V mission: "The painful feeling is getting stronger and stronger, and the internal organs seem to be broken. I can hardly bear it, and feel myself. It's almost gone."

　　In subsequent missions, the astronauts said: "The rocket we were riding on was very comfortable, and there was almost no vibration."

　　Unlike other satellite launch centers in China, the Jiuquan Satellite Launch Center is located in the depths of the Gobi, with no settlements within a radius of tens of kilometers.

Choosing to come here is to choose selfless dedication.

　　However, here is a natural desert, but it is a palace of science.

Heavy and intensive space missions have also given young people a platform and opportunities for rapid growth.

In 2018, Chongqing boy Chen Qimeng chose to come here after graduating from University. He had a nosebleed for a whole month. "It's too dry and completely different from his hometown." Three years later, Chen Qimeng has quickly grown into a business backbone and escorted Yunhai No.1. 02 The satellite, Shenzhou 12 spacecraft and Shenzhou 13 spacecraft were successfully launched.

　　"We will continue to spare no effort to let more young people with dreams and willingness to strive to grow into talents in Dongfeng, the hot land of aerospace." said Jiang Hanmin, party secretary of the Jiuquan Satellite Launch Center.

　　Living in the desolate Gobi, but having a wonderful life.

Just before the National Day holiday, on the eve of the launch of the Shenzhou 13 spacecraft, 120 couples held a grand collective wedding under the launch tower.

Their wedding gift is a blessing video recorded by Chinese astronauts in space: "We send the most sincere blessings from space on the Chinese Space Station, and wish everyone a happy wedding, a hundred years of marriage, and a forever bond."

　　That is the romance of space people.
