Jiuquan, 25 Apr (Xinhua) -- The "giant dragon" took off to chase the heavens -- written on the occasion of the successful launch of the Shenzhou-18 manned spacecraft
Xinhua News Agency reporter
On the evening of April 25, the Long March-2F Yao-18 carrier rocket carried the Shenzhou-18 manned spacecraft and ignited and launched, and astronauts Ye Guangfu, Li Cong, and Li Guangsu took Shenzhou to space.
On the vast Gobi Desert shrouded in night, this is a dazzling light.
In the long journey towards the universe, this is another glorious departure.
The ninth "China Space Day" has just passed, and the third manned mission of the space station application and development stage and the 32nd mission of the manned space project have kicked off.
There was a thunderclap on the ground, and the "dragon" soared to the heavenly palace.
At 20:59 on April 25, the Long March-2F Yao-18 carrier rocket carrying the Shenzhou-18 manned spacecraft was ignited and launched at the Jiuquan Satellite Launch Center, and about 10 minutes later, the Shenzhou-18 manned spacecraft successfully separated from the rocket and entered the predetermined orbit. At present, the astronaut crew is in good condition, and the launch has been a complete success. Photo by Xinhua News Agency reporter Li Gang
Dream chasing, dream come true
Walking on the road of his hometown, the young Li Guangsu was accustomed to hearing the chirping of cicadas, frogs, and the wind blowing wheat waves. One evening, a helicopter flew over his head. The little figure who followed the prestige did not expect that one day he would fly higher.
Similarly, Li Cong, who watched the launch of the Shenzhou 5 manned spacecraft in front of the TV, did not know that he could be selected as the third batch of astronauts in the mainland after 17 years and fight side by side with the heroes in his heart.
And Ye Guangfu, who piloted the fighter plane at night, sighed that the stars above his head were brilliant, but he did not expect that the future journey would be a sea of stars.
"We are fortunate to have caught a great new era. Ye Guangfu, the mainland's first "post-80s" commander, said at a press conference with the Shenzhou 18 astronaut crew.

More than 2,000 years ago, the Chu poet Qu Yuan's long question could only be a long sigh in the long river of history; in the 70s of the 20 th century, due to various reasons, the mainland's first manned space program "Shuguang-1" lasted only five years before it was terminated, and Fang Guojun, one of the astronauts' candidates, had a shattered dream of flying to the sky, and it was difficult to let go of his life in his life.
"Looking up at the sky, in the vast space, there is our own 'space home' for Chinese. Ye Guangfu said that the crew must hand over an excellent answer sheet to the party and the people with a full mental state and a high-spirited attitude of struggle.
"5, 4, 3, 2, 1, ignition!" At 20:59 on the 25th, the command of No. 0 commander Zhao Lei resounded throughout the launch site area. The rocket jumped into the air, drawing a magnificent light trajectory, and the three astronauts flew to the Heavenly Palace.

Although he has participated in 13 manned missions and more than 100 satellite launches, Zhao Lei still finds the roar of rocket launches the most intoxicating.
In 2006, Zhao Lei, who had just graduated, plunged into the desert Gobi, from the arrow operator to the commander of the rocket subsystem, and then to the commander of the Shenzhou 18 manned mission No. 0, he has gone through 18 years.
In fact, giving the command and counting down the ignition in the command hall is only a small part of Commander 0's work. In addition, this position should not only be clear about the technical status and testing mechanism of each system, but also be good at force deployment, good at planning and coordination, and deal with emergencies efficiently and scientifically and efficiently.
"'Number 0' is not a single person, but a team. Zhao Lei said, "Since the launch of the space station mission, the launch density has increased, and we have refined a professional team with normal operation, dedicated supervisors, and capable and efficient." ”
With the continuous improvement of the mainland's comprehensive national strength and the vigorous development of the aerospace industry, astronauts like Zhao Lei not only have the opportunity to pursue their dreams, but also truly feel that the Chinese nation's aerospace dream has become a reality little by little.
After the ignition command was issued, the first detonation on the rocket engine was the pyrotechnics installed in the power system. In the two years since Li Hongyang served as the chief operator, he has participated in 33 satellite launch missions and 7 manned flight missions, which may be the workload of the previous operator for more than ten years.
Cang Huaixing, a 58-year-old expert in space application systems, has similar feelings: "In the past, due to the lack of opportunities and conditions for experiments in space, a project might have to be prepared for ten years or even longer. ”
According to the latest data released on the 24th, China's space station has implemented more than 130 scientific research and application projects in orbit, and has carried out five batches of more than 300 scientific experiment samples using the manned missions from Shenzhou 12 to Shenzhou 16.
The time used is only 3 years.
Great cause, great spirit
On April 24, 1970, the mainland's first artificial satellite was successfully launched at the Jiuquan Satellite Launch Center, and the song "Dongfang Hong" resounded throughout the world, sounding the clarion call for Chinese to explore the vast space.
On this day, 54 years later, still at the Jiuquan Satellite Launch Center, the Shenzhou 18 astronaut crew appeared at Wentian Pavilion. Ye Guangfu, who flew to the sky for the second time, paid tribute to all the strugglers and climbers who selflessly contributed to the motherland's aerospace industry.
The Dongfeng Revolutionary Martyrs Cemetery, 4 kilometers northeast of the Jiuquan Satellite Launch Center, is home to more than 700 heroic ancestors who have loyally and bravely sacrificed their lives for China's aerospace industry. Among them, there are both marshals of the republic and ordinary astronauts.
There is a special tombstone where a small tree grows in front of the monument.
He called the king. In 1965, during a training exercise, an operator accidentally caught fire while draining liquid oxygen. Wang Lai, who rushed to the rescue, also turned into a burning man in an instant.
At the critical moment, Wang Lai took his last breath, took off his colleague's clothes, and ran in the direction away from the personnel and equipment, one step or two...... Leaving 38 charred footprints.
The Si people are gone, but the spirit lives on. On the journey of the Chinese nation towards the sea of stars, thousands of "kings" have come one after another.
In the winter of 2022, propellant escort Cheng Zhenbao found that nitrous tetroxide was leaked due to extremely cold weather during the escort, and entered the carriage for disposal despite the danger of strong acid and corrosion. Half an hour later, the leak was blocked, and when he got up, he found that the protective suit and the stainless steel cabinet were frozen together, and his body had long since lost consciousness.
What kind of career is this? What kind of spirit is this?
Deng Jiaxian, the founder of the "two bombs and one satellite," said, "It is worth dying for it"; Sun Jixian, the first commander, made an oath to "work in the Gobi Desert and be buried in Qingshantou"; and the "seven warriors" who entered the underground launch control room in the mainland's first "two-bomb combination" test wrote in their suicide note: "If you die, you will die on the position and be buried next to the missile."
On September 21, 1992, China's manned space program was officially approved.
Continuing the glory and mission, a large number of scientific research workers packed up their backpacks and threw themselves into this great project aimed at realizing the Chinese nation's thousand-year-old dream of flying into the sky and building a "space homeland" for the Chinese.
Seven years later, on November 20, 1999, the mainland's first independently developed spacecraft, Shenzhou-1, flew into space. Since then, from unmanned to manned, from inside to outside, from single cabin to multi-cabin, and then to the full-configuration Chinese space station, manned spaceflight has continued to create new glories.
Generations of astronauts have worked hard to create the spirit of "two bombs and one satellite" and the spirit of manned spaceflight. With their heroic struggle and selfless dedication, the Chinese people and the Chinese nation have more confidence, stronger waists, and more weight in their speech.
In July 2023, a new famous wall was erected in the Dongfeng Revolutionary Martyrs Cemetery, with a 180-meter-long wall sloping slightly. This design is intended to allow the ancestors to see the scene of the rocket taking off.
On the night of April 25, 2024, the roaring tail flames erupting from the Gobi Desert reflect the British name as desired.

Space power, space power
On April 24, Lin Xiqiang, spokesman for China's manned space program, introduced at the press conference of the Shenzhou-18 manned mission:

"Shenzhou-18 will go up to the experimental device and related samples, and will implement the first domestic in-orbit aquatic ecology research project, with zebrafish and goldfish algae as research objects, establish a stable operation of the space self-circulating aquatic ecosystem in orbit, and achieve a breakthrough in the continent's cultivation of vertebrates in space. ”
"It will also carry out the world's first in-orbit study on the function of plant stem tip stem cells, reveal the adaptation mechanism of plant evolution to gravity, and provide theoretical support for the subsequent directional design of space crops adapted to the space environment. ”
……
For the first time, it has constantly refreshed the imprint of Chinese in space; it has taken off again and again, witnessing the mainland's progressive footprint from a space power to a space power.
"Chang'e" to the moon, "Zhurong" to explore the fire, "Xihe" to go by day, and the Beidou global satellite navigation system was completed and opened...... Not long ago, the name of the new vehicle for the manned lunar exploration mission was announced, and the new-generation manned spacecraft "Dream Boat" and the lunar lander "Lanyue" have entered the stage of initial sample development.
The aerospace industry is a cause to climb the peak of science and technology, and every step of development is inseparable from independent innovation. This space launch is no exception -
The Long March-2F rocket, known as the "magic arrow", has a safety assessment value of 0.99996 and has maintained a 100% launch success rate. Compared with the Chang-2F Yao-17 rocket, the Chang-2F Yao-18 rocket has undergone more than 30 technical status improvements.
The Shenzhou-18 spacecraft is a spacecraft produced in batches. "Although it is a spacecraft in the normal flight phase, we have continuous optimization in terms of technology. Chen Tongxiang of the Fifth Academy of China Aerospace Science and Technology Corporation introduced, "For example, the energy system has been updated, and the endurance has been improved while the weight has been reduced." ”
Hu Yonggang, head of the launch site information center, also talked about the innovation of the launch site system. In recent years, the launch site has carried out "digital and intelligent construction", and through the deployment of a sensing system, the status information of ground facilities and equipment can be obtained in real time, and the full-time information collection and all-factor situation display of filling and launch periods have been realized.
To promote aerospace technology to better benefit the people, innovative achievements are like spring breezes and spring rains, empowering new quality productivity. As far as the eye can see, a hundred flowers are blooming, and it is a good spring.
Up to now, more than 4,000 space application achievements have entered the biological, medical and other industries. Commercial aerospace services such as communications, navigation, and remote sensing are becoming more and more extensive, and related industries are growing rapidly. In 2023, the number of launches and success rate of commercial launch vehicles on the mainland will increase significantly, with a year-on-year increase of 160%, and in 2024, the two sessions of the National People's Congress will be written into the government work report for the first time.
Exploring the vast universe, developing the aerospace industry, and building a space power are the aerospace dreams that we unremittingly pursue. Surprisingly, more and more young people are joining in and injecting a steady stream of motivation into this career.
Luo Jiayu, who was born in 1995, served as the team leader before the Shenzhou-15 manned mission, and Liu Yunyi, who grew up in Dongfeng Space City, chose to return here after graduating from university to take over the baton from his parents......
"China's aerospace is cool, isn't it?" said Chen Muye, a rocket engineer born in 1992. In that year, China's manned space program was officially approved. (Reporter Li Guoli, Liu Yi, Huang Yichen, Liu Yide, Zhao Yeping, Chen Kaizi)
