China’s aerospace exploration of the vast universe (“thirteenth quinquennium”, we have gone this way)
On February 12, the National Space Administration released images of the Tianwen-1 probe’s Mars capture process, my country’s first Mars exploration mission, showing the image of the probe flying over a point near the fire. and braking to light. These images fully record the gradual entrance of Mars into view, the slight vibration of the probe after the engine is started, and the process of the probe’s flight from Mars at night. The solar wing, directional antenna, Martian atmosphere, and surface topography are clearly visible. Tianwen-1’s visit to Mars has become a vivid scene in my country’s journey to build a power in space.
Secretary-General Xi Jinping said: “Exploring the vast universe, developing the aerospace industry and building a space power is our relentless pursuit of the aerospace dream.” Since the “XIII Five-Year Plan”, my country’s aerospace industry has continuously set new records. , the space launch capability has been significantly improved, and space technology has been realized. Jump development, from a great space power to a powerful space power, loud and forceful steps.
Deep space exploration capabilities continue to increase, and fire and moon detection have created multiple firsts
In the early morning of December 17, 2020, in the eager anticipation of the people, Chang’e-5 went on a 23-day space journey, transporting earth pulled from the moon and steadily landed at Bandera’s planned landing area. of Siziwang in Inner Mongolia. This is the first feat for humans to sample and return from the moon in more than 40 years, creating five “firsts in China.” The successful implementation of the Chang’e-5 mission marks that my country has the ability to go back and forth between the earth and the moon, and has achieved the perfect end of the three-step plan of the lunar exploration project circle, “fall and return “, laying a solid foundation for the future lunar and planetary exploration base of my country.
From lunar exploration to exploration of Mars, since the “13th Five Year Plan”, the scope of my country’s space exploration has been ever deeper and deep space exploration capabilities have continued to increase.
Lunar exploration projects continue to innovate and advance, and there are more and more lunar brands belonging to China. On January 3, 2019, the Chang’e-4 probe successfully landed on the back of the moon and sent the world’s first short-range image of the back of the moon through the relay star “Magpie Bridge “, revealing the mystery of the moon. return. This is the first time that a human probe has made a soft landing on the back of the moon, opening a new chapter in human lunar exploration. So far, the Yutu-2 lunar rover has a cumulative mileage of more than 600 meters, making it the lunar rover that has worked on the moon for the longest time.
The exploration of Mars starts a new interstellar journey and the planetary exploration forms a general concept. On July 23, 2020, my country’s first Mars exploration mission, the Tianwen-1 probe, officially set sail from the Wenchang space launch site in China. It is a space exploration with a global focus. Through a single launch, the three missions of orbit, landing and patrolling and detection of Mars have been carried out, which is the first time in the history of the world’s space flight. A series of advancements in key technologies such as the vast expanse of the deep sky and more than 100 million kilometers of measurement and control technology have made every move of Tianwen No. 1 perfect and orderly. Taking as a starting point the exploration of Mars, our country has determined the next direction in the field of deep space exploration, more distant planets like Jupiter and Saturn await us to explore one by one.
Manned space flight enters a new stage, construction of the space station begins
Since the “Thirteenth Five-Year Plan”, my country’s manned spaceflight projects have successively carried out major missions such as Long March 7, Tiangong 2, Shenzhou 11, Tianzhou 1 and Long March 5, continuously setting new heights in the manned space flights from China. The dream of staying in space is one step closer.
“Shenzhou” perfectly holds hands with “Tiangong” to complete an exciting “kiss” in space. “The spacecraft turned 30 meters to support itself, and the spacecraft finally approached, the state was normal, the docking mechanism was captured, the docking ring began to withdraw, and the docking mechanism locked …” 3:31 on October 19, 2016, together with the issued instructions, the Shenzhou 11 manned spacecraft and the Tiangong-2 space laboratory successfully conducted automatic rendezvous and docking. During this manned mission, Jing Haipeng and Chen Dong remained in orbit for 33 days, setting the record for the longest-lasting Chinese astronaut in space.
Tianzhou-1 completed the first “space refueling”, filling the technological gap in the aerospace field. In April 2017, my country’s first cargo spacecraft, Tianzhou-1, was launched into space, and the rendezvous and docking with the orbiting Tiangong-2 space laboratory, and the first propellant supplementation test in orbit. The smooth implementation of “Space Refueling” has made my country the third country in the world to independently master this key technology.
The construction of the space station is opened and China’s space flight enters the era of the space station. “5, 4, 3, 2, 1, turn it on!” On May 5, 2020, the Long March 5B carrier rocket soared into the sky and headed straight for the sky. A few days later, the return cabin of the new generation manned spacecraft test ship successfully returned and the test was a complete success. As the first flight mission of the third step of China’s manned space project, the success of this mission marks the opening of the construction of China’s space station, and China’s aerospace industry has officially entered the space station era.
Climb to the heights and become self-sufficient, aerospace science and technology achieve great development
Since the “Thirteenth Five-Year Plan”, the level of aerospace science and technology in my country has grown rapidly. A number of major independent innovations, such as large rockets, Beidou navigation, and high-resolution satellites, have quickly appeared … Achievements, condensing the sweat and wisdom of Chinese astronauts, and demonstrating China’s determination and courage to achieve technological self-sufficiency and self-sufficiency.
The technological level of the launch vehicle reached a new record. The rocket development project adhere to independent innovation and bravely rise to the top. It has surpassed many key technologies such as large-size fairing separation technology, large-diameter rocket and cockpit connection separation technology, direct deviation to large-thrust orbit. precision control technology and other key key technologies The loading capacity has reached world-class capacity. Today, my country’s “Long March” carrier rocket series has flourished at many points: the Long March 11 carrier rocket was launched in the Yellow Sea, and my country’s first carrier rocket was successfully launched into the sea. ; The Long March 8 flew successfully for the first time, which is closely related to the Long March 5, Long March 6 and Long March. The number seven and other components constitute a new generation of carrier rocket type spectrum with a reasonable design.
The “Beidou of China” became the “Beidou of the world”. On July 31, 2020, the Beidou-3 Global Navigation Satellite System was officially launched. Thereafter, anywhere in the world, the navigation, positioning and timing services of the Beidou system can be obtained. Since the “13th Five-Year Plan,” Chinese astronauts have raced against time and stepped up their efforts to tackle key problems. The location rate of Beidou navigation satellites and key components has reached 100%. My country has become the third country in the world to independently own a global satellite navigation system. China Beidou has really done it. Starlight Global.
Aerospace science and technology benefit people’s livelihoods. Since the “13th Five-Year Plan”, my country’s civil space infrastructure has been continuously improved. The “high score family” is getting stronger and stronger, and satellite communications, satellite navigation and satellite remote sensing are widely used in many fields. More than 2,000 aerospace technology achievements have been transplanted and deeply cultivated, spawning new forms of business such as smart cities and space replication. Most memorable is that in the fight against the new corona pneumonia epidemic, the combination of high scores and precise Beidou mapping, high-precision positioning, the entire network witnessed the construction of “China Speed” of Vulcan Mountain Hospital and Leishen Mountain Hospital. , and the effect of radiation against the epidemic of science and technology was highlighted.
The starry sky is vast and endless, and the exploration is endless. The “14th Five-Year Plan” began, and China Aerospace will continue to advance on a new journey.
