China's aerospace exploration of the vast universe ("13th Five-Year", we have gone through this way)
On February 12, the National Space Administration released images of the Mars capture process of the Tianwen-1 probe, my country's first Mars exploration mission, showing the image of the probe flying over a near-fire point and braking to ignite.
These images fully record the gradual entry of Mars into view, the slight vibration of the probe after the engine is ignited, and the process of the probe flying from Mars to 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.
General Secretary Xi Jinping pointed out: "Exploring the vast universe, developing aerospace industry, and building an aerospace power is our unremitting aerospace dream." Since the "13th Five-Year Plan", my country's aerospace industry has continuously set new records, and space launch capabilities have been significantly improved, and space technology has been realized. Leapfrogging development, from a big space power to a powerful space power, sonorous and forceful steps.
Deep space exploration capabilities continue to increase, and lunar and fire detection have created multiple firsts
In the early morning of December 17, 2020, in the eager anticipation of people, Chang'e-5 experienced a 23-day space journey, carrying soil taken from the moon, and landed steadily in the scheduled landing area of Siziwang Banner in Inner Mongolia.
This is the first feat of human beings to sample and return from the moon after more than 40 years, creating 5 "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 realized the perfect ending of the three-step plan of the lunar exploration project "circumnavigation, landing, and return", laying a solid foundation for my country's future lunar and planetary exploration. basis.
From lunar exploration to Mars exploration, since the "13th Five-Year Plan", my country's space exploration range has been deeper and wider, and deep space exploration capabilities have continued to increase.
Lunar exploration projects continue to innovate and make breakthroughs, and there are more and more lunar marks belonging to China.
On January 3, 2019, the Chang'e-4 probe successfully landed on the back of the moon and sent back the world’s first close-range image of the back of the moon through the "Magpie Bridge" relay star, revealing the mystery of the back of the moon .
This is the first time that a human probe has achieved a soft landing on the back of the moon, opening a new chapter in human lunar exploration.
Up to now, 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.
Mars exploration starts a new interstellar journey, and planetary exploration forms an overall concept.
On July 23, 2020, my country’s first Mars exploration mission, Tianwen-1, officially set sail at the Wenchang Space Launch Site in China.
This is a space exploration with a global focus. Through a single launch, the three missions of Mars orbiting, landing, and patrolling and detection have been achieved, which is the first time in the world's space history.
A series of breakthroughs in key core technologies such as the vast expanse of the deep sky and over 100 million kilometers of measurement and control technology have made every movement of Tianwen No. 1 perfect and neat.
Taking the exploration of Mars as the starting point, our country has determined the next direction in the field of deep space exploration. More distant planets such as Jupiter and Saturn are waiting for us to explore one by one.
Manned spaceflight enters a new stage, the construction of the space station begins
Since the "13th Five-Year Plan", my country's manned spaceflight projects have successively performed major missions such as Long March 7, Tiangong 2, Shenzhou 11, Tianzhou 1, and Long March 5B, constantly setting new heights in China's manned spaceflight. The dream of staying in space is one step closer.
"Shenzhou" perfectly held hands with "Tiangong" to complete a thrilling "kiss" in space.
"The spacecraft turned 30 meters to hold, and the spacecraft finally approached, the state was normal, the docking mechanism was captured, the docking ring began to be pulled back, and the docking mechanism was locked..." At 3:31 on October 19, 2016, following instructions were issued. , Shenzhou 11 manned spacecraft and Tiangong-2 space laboratory successfully realized automatic rendezvous and docking.
During this manned mission, Jing Haipeng and Chen Dong stayed in orbit for 33 days, setting the record for the longest Chinese astronaut stayed 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 completed the rendezvous and docking with the Tiangong-2 space laboratory in orbit, and the first in-orbit propellant replenishment and other tests.
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 has begun, and China's aerospace has entered the space station era.
"5, 4, 3, 2, 1, light it up!" On May 5, 2020, the Long March 5B carrier rocket soared into the sky and went straight to the sky.
A few days later, the return cabin of the new generation manned spacecraft test ship returned successfully, 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 has officially entered the space station era.
Climb the heights and become self-reliant, aerospace science and technology achieve leapfrog development
Since the "Thirteenth Five-Year Plan", my country's aerospace science and technology level has achieved leapfrog development. A series of important independent innovations such as large rockets, Beidou navigation, and high-resolution satellites have emerged. Achievement, condensing the sweat and wisdom of Chinese astronauts, shows China's determination and courage to achieve technological self-reliance and self-reliance.
The technological level of the launch vehicle reached a new high.
The rocket development project adheres to independent innovation and bravely climbs to the peak. It has broken through many key core technologies such as large-size fairing separation technology, large-diameter cabin and rocket connection separation technology, large-thrust direct-to-orbit deviation precision control technology, etc., and its carrying capacity has reached world-class capacity. Level.
At present, my country’s “Long March” series of carrier rockets have blossomed 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 at sea; the Long March 8 successfully flew for the first time, which is closely related to the Long March 5, Long March 6, and Long March. No. 7 and other components constitute a new generation of carrier rocket type spectrum with reasonable layout.
"China's Beidou" became the "World's Beidou".
On July 31, 2020, the Beidou-3 global satellite navigation system was officially opened.
From then on, in any place 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 localization 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 truly achieved it. Starlight Global.
Aerospace science and technology benefit people's livelihood.
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, giving birth to new business forms such as smart cities and space breeding.
The most memorable thing is that in the fight against the new crown pneumonia epidemic, the combination of high scores and Beidou precise mapping and high-precision positioning, the whole network witnessed the construction of "China Speed" of Vulcan Mountain Hospital and Leishen Mountain Hospital, and the anti-epidemic radiation effect of science and technology was prominent.
The starry sky is vast and endless, and the exploration is endless.
The "14th Five-Year Plan" started, and China Aerospace will continue to forge ahead on a new journey.
