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.
In the future, with the continuous development of the new generation of long march series launch vehicles, China's launch vehicle capability will once again achieve a new leap: the new generation of medium-sized launch vehicles such as long March 6 A, Long March 7 A and Long March 8 are being developed as planned to realize the "upgrading" of the launch vehicle as a whole; The Long March 5 rocket will successively carry out several important launch missions to support the steady implementation of major engineering projects such as the third phase of China's lunar exploration, lunar sampling and return, the launch of Mars probe in 2020, and the construction of the core module of the space station; The heavy launch vehicle is expected to make its first flight in 2030, making the level and capacity of China's space transportation system rank among the world's space powers... At the same time, China's space transportation mode will also achieve major breakthroughs from one-time use to reuse, from single space transportation to the combination of space transportation and space operation. It is not hard to imagine that with the continuous enhancement of China's comprehensive Aerospace strength, the long march series launch vehicles will carry China's aerospace dream, condense the struggle spirit of Chinese aerospace people, fly to space again and again, and open the "new Long March" of China's aerospace industry.
Looking up at the stars, the journey is long. 300 launches are only the first step in the "Long March" of China's aerospace industry, and there are 500, 1000 or even more breakthroughs waiting for us to make unremitting efforts. I believe that in the future, we will be able to create more space miracles, realize a new and greater "space dream" and leave a more wonderful Chinese mark in the vast universe.
The exciting moment finally came. When Shenzhou 13 was launched, we were all worried that it could not send three astronauts into space to connect with Tiangong 1. The fire when it ignited was too large. I wondered whether it would cause a fire?
With the successful flight of Shenzhou 13 into the blue sky, my doubts subsided bit by bit, and the big stone in my heart finally landed. Then the two small rockets on the rocket fell down, followed by the shell and an auxiliary propeller. Finally, all unnecessary things fell down, and the solar panel stretched out. Shenzhou 13 finally entered the predetermined orbit. Shenzhou 13 was launched successfully! All the students are cheering because this is a new step in China's exploration of the universe and another starting point for China's exploration of the mysteries of the universe.
At this moment, I have a new ideal - to be an excellent astronaut!
By opening the door of the space station era, China Aerospace has demonstrated its confidence in unswervingly following the path of independent innovation with Chinese characteristics. The launch time of the long march 5B carrier rocket was announced in advance, and finally the rocket realized the "zero window" launch without delay. From Shenzhou 9, Shenzhou 10 to the Long March 5 B carrier rocket... The launch times of several missions were announced in advance and accurate to minutes, fully demonstrating the astronauts' confidence. The confidence comes from the 16 victories in manned spaceflight since the launch of shenzhou-1 spacecraft, and also from the implementation and persistence of the awareness of quality first and safety first in the manned spaceflight project with the most complex system and safety requirements. Self confidence is not only tempered by "grinding a sword in ten years", but also thirsty for knowledge by climbing and challenging the unknown. After the successful launch, the screen in the hall of Wenchang space launch site printed such a line: dare to overcome all difficulties and obstacles and climb the peak of space science and technology. Struggle is a reward for those who struggle. China's aerospace sword points to the vast sky, and the "Long March" is always on the road.
Exploring the vast universe, developing the aerospace industry and building a aerospace power are our unremitting Aerospace dream. From the opening of the space age with the first man-made earth satellite "dongfanghong-1" XX years ago to today's space station era, China's aerospace has embarked on a new journey again. The space station is an extremely complex and challenging step, but the huge harvest will be unparalleled. It can accelerate the pace of exploration, development and utilization of the universe in China and even mankind. The leap of space station and aerospace technology can also promote Aerospace achievements and benefit social development and people's life. As an initiative in near earth space, the construction of the space station will lay the foundation for further realizing the longer-term goals of manned lunar exploration and Mars exploration, and become a landmark innovative practice in the construction of aerospace serving the country and a scientific and technological power.
Today, due to the limited resources of the earth, the world's aerospace powers have stepped into outer space. The space is vast and has rich space resources, such as high vacuum, solar energy, moon, micro planets and so on.
In addition, closely related to people's life, GPS navigation system is inseparable from the development of aviation. In recent years, space technology has made remarkable achievements in developing spacecraft high-position and high-speed resources to obtain, transmit and forward information, and has obtained great benefits, such as the wide application of communication satellites and remote sensing satellites.
On the other hand, with the rapid development of military spacecraft, various new space weapons such as military satellites, manned spacecraft, ballistic missiles and anti ballistic missiles have formed an integrated space battlefield military system and will play an important role in joint campaigns. As we all know, without a solid national defense, it is difficult to guarantee our happy life.
Without today's investment, there will be no tomorrow. The progress of aerospace industry will drive the development of relevant industries. The application of Aerospace Science and technology will have a significant impact on mankind. Only with the continuous progress of society and the continuous development of science and technology, our life will be more and more beautiful.
