On the morning of October 16, Yang Hong, the chief designer of the space station system of China's manned space project and a researcher of the General Design Department of the Fifth Academy of Aerospace Science and Technology Group, listened to the 20th National Congress report in the Great Hall of the People.
In his report, General Secretary Xi Jinping once again mentioned "accelerating the construction of a strong aerospace country", and praised the innovations in the aerospace field such as manned spaceflight, lunar exploration and fire exploration, and satellite navigation, which made Yang Hong extremely excited.
Since the 18th National Congress of the Communist Party of China, China's aerospace industry has entered the fast lane of innovation and development.
In 2013, General Secretary Xi Jinping pointed out: "Developing the aerospace industry and building a strong aerospace country is our unremitting pursuit of the aerospace dream." He issued a mobilization order to all astronauts to build a strong aerospace country.
Facing the development of space technology, astronauts have transformed the general secretary's cordial care and scientific guidance into vivid practices to accelerate the construction of a space power.
Traveling in the Heavenly Palace, Chang'e catching the moon, Tianwen exploring the fire, Beidou Zetianxia... One by one, China was proudly sent into the vast universe, playing a new movement in the construction of a aerospace power.
Pursue the dream for nine days and build the Chinese people's own space home
Every one and a half hours, a unique "star" will cross the sky, causing space enthusiasts to chase after shooting.
The name of this "star" is "Heavenly Palace".
In order to build the Chinese people's own space homeland, the astronauts firmly follow the "three-step" strategy of the manned space project.
As the main force of my country's space technology development, the research team of the Fifth Academy of Aerospace Science and Technology Group has independently completed the whole process of China's space station from design, construction to on-orbit operation in the past ten years.
In 2013, the Shenzhou 10 manned spacecraft and the Tiangong-1 target aircraft rendezvous and docked and flew in combination, completing the first practical flight of my country's manned spacecraft; The key technology of a generation of multi-purpose spacecraft; in the same year, the Tiangong-2 and Shenzhou-11 manned missions achieved the first mid-term in-orbit astronaut residency; With the rendezvous and docking of the laboratories, the second step of the manned spaceflight project has been completed, and my country has fully grasped the key technologies required for the construction of the space station.
On April 29, 2021, the Tianhe core module, the first module of the Chinese space station, was successfully launched, kicking off the third step of my country's manned spaceflight project.
The research and development team has worked hard in many places and on multiple lines, and has fully guaranteed the success of the manned spaceflight project's 8 launches, 2 returns, and 6 out-of-vehicle missions.
"At present, we have completed the on-orbit verification mission of key technologies of the Chinese space station, and in the near future we will launch the third module of the space station - the Mengtian module." Yang Hong said, "We must carefully organize, prepare, and implement carefully to ensure that The space station assembly and construction mission was a complete success."
Make great strides, and realize the leap from the Earth-Moon system to the interplanetary system
For viewing the moon, ordinary people often "send lovesickness", but because of "Chang'e", astronauts will have deeper feelings.
"There are Chang'e 3 and 5 on the front of the moon, and Chang'e 4 on the back, and all of these are developed by us." The Lunar Exploration Team of the Fifth Academy said proudly.
In 2013, Chang'e-3 successfully landed on the moon and carried out a lunar inspection and survey, realizing my country's first soft landing direct detection of extraterrestrial celestial bodies, marking the full realization of the strategic goal of the second step of my country's lunar exploration project.
In 2019, Chang'e-4 achieved the first soft landing of human spacecraft on the far side of the moon, patrol detection and relay communication between the far side of the moon and the earth, leaving China's footprint on the back of the moon.
As the pioneer of the third phase of lunar exploration, the Chang'e-5 reentry and return flight test vehicle was successfully launched and returned in 2014. my country has successfully broken through and mastered the key technology of spacecraft reentry and return at a speed close to the second cosmic speed.
In 2020, the Chang'e 5 spacecraft will return samples of extraterrestrial celestial bodies in my country for the first time, and China's lunar exploration project will successfully complete the three-step plan of "circling and falling back".
The success rate of global lunar exploration missions is about 50%, and China's lunar exploration project has six victories and six victories. The first lunar soft landing, the first lunar back landing, and the first lunar surface sampling return have all been successful. Such a perfect performance can be described as a world aerospace history. is unique.
In addition to the moon, which is 380,000 kilometers away, Chinese astronauts have set their sights on Mars, which is 400 million kilometers away.
On July 23, 2020, the Tianwen-1 probe was successfully launched and successfully landed on Mars after a long journey of more than 9 months, making my country the second country in the world to successfully land and inspect Mars.
"It is the first time in the history of human spaceflight to complete the three goals of Mars orbiting, landing and inspection in one mission," said Sun Zezhou, chief designer of the Tianwen-1 probe of the Fifth Academy.
So far, my country has taken an important step in the journey of interstellar exploration, realizing the leap from the Earth-Moon system to the interplanetary system.
Going to the next level, a new starting point for the aerospace industry to create new achievements
In December 2012, the Beidou satellite navigation system officially provided regional services, marking the completion of the second-step strategic goal of my country's Beidou system construction.
The Beidou development team is non-stop.
They have conquered more than 160 key core technologies such as inter-satellite links with independent intellectual property rights, and achieved 100% localization of core components... They have completed the deployment of the Beidou-3 global satellite navigation system constellation in less than 3 years. The Beidou system has achieved a historic leap from existence to excellence, from regional to global.
On July 31, 2020, the Beidou-3 global satellite navigation system was officially completed and opened, marking the establishment of an independent, open and compatible global satellite navigation system in China.
my country has become the third country in the world to independently own a global satellite navigation system.
In addition to the above-mentioned major projects, over the past decade, China's space technology has flourished and competed in many fields.
In the field of remote sensing, the high-resolution earth observation system project has come to a successful conclusion, and my country has ushered in a new era of multi-layer, three-dimensional, multi-angle, all-round and all-weather earth observation; in the field of communications, my country has launched the first high-throughput satellite Satellite Zhongxing No. 16, my country's communication satellite has entered the era of Internet application; in the field of technical testing, the practice of No. 20 satellite benchmarking the world's most advanced technology level of super large public satellite platform marks the realization of my country's new generation of large-scale geosynchronous orbit satellite platform technology In the field of space science, Shishi No. 10 Space Microgravity Science Experiment Satellite, Hard X-ray Modulation Telescope Satellite, Zhang Heng No. 1 Satellite, Tianqin No. 1 Gravitational Wave Detection Experiment Satellite, etc. The development of my country's space science satellite system development technology, detection load technology and scientific application technology...
Taking the Fifth Academy of Aerospace Science and Technology Group as an example, from the 18th National Congress of the Communist Party of China to September 30, 2022, the Academy has developed and successfully launched a total of 262 spacecraft in the past ten years, accounting for the total research and development in the 54 years since its establishment. 65.8% of the number.
Standing at a new starting point, the astronauts feel a great responsibility.
Yang Hong said: "We must earnestly study and comprehend General Secretary Xi Jinping's important expositions on the aerospace industry, fully understand the far-reaching significance of the space station project as an important leading project for the construction of a scientific and technological power and a strong aerospace power, and establish new ones in order to achieve a high level of self-reliance and self-improvement in my country's aerospace science and technology. merit.” ◎Sun Shuyi Wu Xiaobo reporter Fu Yifei (source: Science and Technology Daily)
