China's high-tech development has advanced by leaps and bounds, the launch of Shenzhou 7 has been successful, and a major breakthrough has been made in 5g Internet research and industrialization. China's "first world-class high-speed railway has been opened between Beijing and Tianjin," the first research results of Chinese genome sequence have been published, "the construction task of major transformation project of Beijing electron positron collider has been successfully completed." Dawning 5000A ranks among the top ten supercomputers in the world.
The Dragon dives deep and Chang'e explores the moon. China's scientific and technological strength has made continuous progress. The continuous emergence of major scientific and technological achievements and the increasingly active scientific and technological innovation have injected new vitality into high-quality economic development.
The Millennium dream is now realized. On July 23 last year, tianwen-1 was launched by the long March-5 remote-4 carrier rocket at Wenchang space launch site and successfully entered the predetermined orbit. Tianwen-1 arrived on Mars in February 2021 to capture Mars. In May 2021, we will select an opportunity to carry out orbit descent, separate the landing inspector from the orbiter, soft land the Martian surface, drive the rover away from the landing platform, carry out inspection and exploration, and scientifically explore the surface morphology, soil characteristics, material composition, water ice, atmosphere, ionosphere, magnetic field and other aspects of Mars, so as to realize China's technological leap in the field of deep space exploration [5]. Deep space exploration will promote the all-round development of space science, space technology and space applications, and make greater contributions to serving the overall situation of national development and promoting human well-being.
As of February 3, 2021, the total flight mileage of "tianwen-1" probe has exceeded 450 million kilometers, about 170 million kilometers away from the earth.
We are standing at the historical intersection of the "two centenaries", and the new journey of building a modern socialist country in an all-round way is about to begin. The journey is long, only struggle. Through struggle, we cut through thorns and thorns and walked through thousands of rivers and mountains. We will continue to struggle, move forward bravely and create more brilliant brilliance!
The astronauts of Shenzhou 13 will stay in orbit for six months as planned. During these six months, their main work is to further verify the key technologies for the construction and operation of the space station. Specifically, it is necessary to cooperate with the core module, Tianzhou II and Tianzhou III for further verification.
If science and technology is strong, the country is strong. The road of self-confidence is successful and praises China's aerospace. The successful launch of Shenzhou 13 manned spacecraft once again makes us feel the strength of our motherland.
In the early morning of the 16th, Shenzhou 13 was successfully launched. At this time, it was less than one month before the successful return of Shenzhou 12 manned spacecraft. The new "space travel trio" composed of Zhai Zhigang, Wang Yaping and ye Guangfu took a manned spacecraft to the Chinese space station. This mission will achieve multiple "first times" such as radial rendezvous and docking with the core module and transfer from the rescue ship to the formal mission ship. It will also carry out more space science experiments and technical experiments on the basis of the Shenzhou 12 mission.
In 2003, Shenzhou V spacecraft was launched with Yang Liwei from Jiuquan Satellite Launch Center. It took 21 hours and 23 minutes to successfully return to the ground, realizing the Chinese nation's dream of flying for the first time. Over the past 18 years, there have been seven manned flights, with intervals ranging from years to months. The frequency of "business trips" is faster, the connection is smoother, and the preparation is more leisurely, showing China's ability to stand on its own in science and technology; From "one-day tour" to "quarterly Tour", and then to the "in-depth Tour" of this half year, the "space business trip" takes longer, takes greater, farther and more firm steps, demonstrating the pride of the self-confidence of a big country.
