　　"Chang'e" lunar exploration, "Zhurong" fire exploration, "Xihe" day by day, the Chinese people are constantly marching toward the moon, Mars, the sun and other planets, and the footsteps of inquiring the sky have never stopped, and the ancient myths and dreams have become reality one by one.

　　The realization of the "Legend of the Gods" carries the Chinese ambition and romance to explore the vast universe. Behind the cross-planet is the wisdom and hard work of aerospace central enterprises and countless astronauts.

"Chang'e" flies to the moon

　　In December 2020, when Chang'e 5 successfully brought back about 2 kilograms of lunar soil from the moon, an old newspaper became popular on the Internet.

　　This 2005 "Science Discovery" reported on the three-step strategy and timetable of China's lunar exploration "circling, falling, and returning". The same page also listed the lunar exploration plans of Japan, India, Russia and the United States.

But what is embarrassing is that only China has achieved its own "Lunar Exploration Flag" as scheduled.

　　"Only China takes it seriously."

Looking back at the journey of "Chang'e" to the moon, this is a steady and steady journey across the country.

　　In 2007, Chang'e-1 successfully entered the lunar orbit and sent back three-dimensional images of the moon; in 2010, Chang'e-2 achieved on-time launch, accurate orbital, direct Earth-to-moon transfer, and successful circumnavigation of the moon; in 2013, Chang'e-3 achieved the first time. Soft landing and inspection survey of Chinese spacecraft on extraterrestrial celestial bodies; in 2019, Chang'e-4 achieved the first soft landing and inspection survey of spacecraft on the back of the moon in human history, and realized relay communication between the back of the moon and the earth for the first time; 2020 In 2008, Chang'e 5 achieved the return of samples from extraterrestrial objects in my country for the first time.

　　Adhering to the lunar exploration spirit of chasing dreams, daring to explore, cooperating to tackle difficulties, and win-win cooperation, aerospace central enterprises and countless astronauts have persevered and made unremitting efforts. "Tackling key problems, advancing "a game of chess" together, and iteratively improving "integration", the millennium dream of the Chinese nation "to embrace the moon in nine days" has been realized.

　　Sun Zezhou from the Fifth Academy of China Aerospace Science and Technology Corporation is the chief designer of the Chang'e 3 and 4 probe systems, and the chief designer of the Tianwen-1 Mars probe system. , facing enormous pressure and challenges.

　　Among them, Chang'e-4 will land on the far side of the moon, which has never been seen in human history. The back of the moon cannot communicate directly with the ground, and the risk is huge.

Sun Zezhou led the research team to carry out technical research day and night, and built the Chang'e-4 detector system scheme of "lander + patroller + relay satellite", breaking through the core keys such as accurate and safe soft landing under rough terrain and full-time relay communication technology, and successfully achieved the feat of soft landing and reconnaissance on the far side of the moon.

On June 11, 2021, the National Space Administration announced the panorama of the landing site, the topography of Mars, the "China Imprint" and the "Patrol Group Photo" taken by the "Zhurong" rover.

"Zhu Rong" fire detection

　　From the moon to Mars, it means a span from 380,000 kilometers to 400 million kilometers.

　　On May 15, 2021, the Tianwen-1 probe landed on Mars, taking an important step in my country's interstellar exploration journey, realizing the leap from the Earth-Moon system to the interplanetary system, leaving the Chinese imprint on Mars for the first time. Make our country the second country to successfully land on Mars.

　　The Tianwen-1 Mars probe was developed by the General Manager of the Fifth Academy of Aerospace Science and Technology Group. It consists of an orbiter and a landing rover. The landing rover includes the "Zhurong" Mars rover and an entry module.

　　Zhu Rong is revered as the earliest god of fire in traditional Chinese culture, symbolizing that ancestors used fire to illuminate the earth and bring light.

On May 22, 2021, the "Zhurong" rover successfully landed on the surface of Mars and began to patrol and explore.

my country's first Mars exploration mission achieved the three goals of "circling, orbiting, and patrolling" at one time.

　　As the chief designer of the Tianwen-1 Mars rover system, Sun Zezhou choked up when he was interviewed by the media.

　　You must know that Tianwen No. 1 is actually competing with the UAE's Hope and the US's Perseverance.

"The UAE's 'Hope' has successfully orbited, and the US 'Perseverance' has successfully landed. At this time, Tianwen-1 is not as simple as a task in my mind. I am not very good at expressing my pressure in words. degree,” he said.

　　"The difficulty of Mars exists objectively. Why do we succeed? The success lies in our pursuit of excellence in our work and the pursuit of excellence in our work standards." Sun Zezhou attended the "Model Responsibility of Central Enterprises" on June 21, 2021, on behalf of party members of central enterprises. said at a press conference.

At 18:51 on October 14, 2021, China successfully launched the first solar exploration science and technology test satellite "Xihe" using the Long March 2D carrier rocket at the Taiyuan Satellite Launch Center.

"Xihe" Day by Day

　　"Imitate Xi and Yu Tianma, and aim to herd the stars in the sky."

In 2021, with the successful launch of my country's first solar exploration science and technology test satellite "Xihe", China has also entered the era of "exploration of the sun".

　　The name of the satellite is inspired by the sun goddess Xihe in ancient Chinese mythology, which symbolizes the origin and expansion of China's exploration of the sun.

　　People regard "Xihe" as my country's first dedicated "photographer" for the sun.

The "Xihe" satellite was developed by the General Manager of the Eighth Academy of Aerospace Science and Technology Group. It operates in a sun-synchronous orbit at an altitude of 517 kilometers. , equivalent to a CT scan of the solar atmosphere.

　　In August 2022, the results of the "Xihe" solar exploration were officially released, setting five international firsts, including the world's first space solar Hα band spectral scanning imaging, and the world's first atomic frequency discrimination solar velocimetry navigator on-orbit verification.

　　At present, China has achieved "Chang'e" lunar exploration, "Zhurong" fire exploration, and "Xihe" day-to-day in space science and exploration, covering the main types of celestial bodies in the solar system.

From the moon to Mars to the sun, the Chinese have taken a steady and farther step across the planet.

　　Space exploration never ends.

The people of aerospace central enterprises will continue to innovate and climb the peak bravely, and make greater contributions to the construction of a strong country in aerospace and science and technology.

As Sun Zezhou said, in the future, new breakthroughs in technology and new scientific discoveries will be realized through the implementation of major aerospace projects such as asteroid detection, Mars sampling return, and Jupiter galaxy orbit, and contribute more Chinese wisdom to the peaceful use of space by mankind , China's plan, China's power.
