"Flying dreams never lose weight, and scientific dreams have unlimited tension." Eight years ago, "space teacher" Wang Yaping gave a lesson to more than 60 million students in China. Now she is once again on a trip to space, and will become the first female astronaut in China and the first female astronaut in China. Looking at the sound, the mysterious and distant deep space is getting closer and closer to us, and the beautiful "flying dream" is becoming a reality. /kloc-in the early morning of 0/6, Shenzhou XIII was successfully launched, less than a month after the successful return of the Shenzhou XII manned spacecraft. A new "space travel trio" composed of Zhai Zhigang, Wang Yaping and Ye Guangfu went to China Space Station by manned spacecraft. This mission will achieve a number of "firsts" such as radial rendezvous and docking with the core cabin, transfer from a rescue ship to a formal mission ship, and will carry out more space science experiments and technical experiments on the basis of the Shenzhou 12 mission.
"Sit on the floor, travel 80,000 miles a day, and look at thousands of rivers." In 2003, the Shenzhou 5 spacecraft was launched with Yang Liwei at Jiuquan Satellite Launch Center, and it took 2 1 hour and 23 minutes to successfully return to the ground, realizing the Chinese nation's dream of flying for the first time. Since 18, there have been seven manned flights, with the interval from to. The frequency of "business trip" is faster, the contact is smoother and the preparation is more leisurely, which shows China's ability to stand on its own feet in science and technology. From "one-day tour" to "seasonal tour" to "in-depth tour" lasting for half a year, the "space business trip" takes longer, takes bigger, farther and firmer steps, and shows the self-confidence and pride of a big country.

Shenzhou XIII manned spacecraft will be launched in the early morning of June 10. In response, Zhao, a spokesman for the Ministry of Foreign Affairs of China, said on June 5438+05 that less than a month ago, China ushered in the triumph of the Shenzhou 12 manned spacecraft, and in the early morning of June 5438+06, China will once again watch the Shenzhou 13 fly into space with excitement. "This not only vividly interprets China's manned spaceflight spirit, which is particularly hard-working, especially capable of fighting, especially tackling key problems, and especially dedicated, but also reflects the scientific exploration spirit of China people who dare to pursue their dreams, dare to explore and never stop." At the regular press conference of the Ministry of Foreign Affairs held on the same day, Zhao said that on June 5438+05, the press conference of Shenzhou 13 manned mission was held in Jiuquan Satellite Launch Center, and the spokesman of China's manned spaceflight project introduced the relevant situation. Shenzhou 13 manned mission is the key technology verification stage of China Space Station, and Chang 'e-6 mission is the decisive battle and the final battle at this stage, and it is also the key battle to link the past with the future in the on-orbit construction of the space station.
"What I want to say is that the Shenzhou XIII mission shows China's new efforts and contributions to manned space exploration, the common cause of mankind. China will continue to increase the depth and breadth of international cooperation and exchanges in the field of manned spaceflight, and make positive contributions to mankind's exploration of the mysteries of the universe, the peaceful use of space, and the promotion of building a community of human destiny. " He said.

According to media reports, Shenzhou XIII manned mission is the sixth and last mission in the key technology verification stage of the space station. Its main purposes are:
① Carry out experiments on key technologies of space station assembly and construction, such as mechanical arm assisted cabin transfer and manual teleoperation;
(2) Conduct 2-3 extravehicular activities, and install dual-arm combined adapters and suspension devices of large and small mechanical arms to prepare for the subsequent space station construction tasks;
(3) Further verify the health, life and work support technology of astronauts staying in orbit for 6 months;
④ Carry out scientific and technological experiments and applications in space medicine, microgravity physics and other fields, and carry out diversified popular science education activities;
⑤ Comprehensive evaluation of the functional performance of each system in the project, the model of mobile phone version and the matching between systems.

Fight the Gobi desert, dedicate your youthful life, break through the blockade and monopoly, and build a big country. Under the leadership of the Party, generations of soldiers and scientific and technological workers have made unremitting efforts to create brilliant achievements represented by "two bombs and one satellite", manned space flight and lunar exploration, and embarked on a development path of self-reliance and independent innovation. The launch of Shenzhou series spacecraft bears the Chinese nation's space dream and shows the great ambition of China people to "dare to board for nine days". These great achievements reflect the great spirit of the Party leading the people to realize the rejuvenation of the Chinese nation, and inspire party member to seize the strategic opportunity, persist in innovation-driven development, bravely climb the peak of science and technology, and write a new chapter in the Chinese dream of realizing the great rejuvenation of the Chinese nation. Nie, Zhang Aiping, Li, Qian Xuesen, Sun Jiadong, Wang Yongzhi, all great names will go down in the history of the Republic of China. The veteran I interviewed is also an ordinary and great member of this glorious group.

Manned space flight is the most complex, difficult and demanding system engineering in human space activities. According to the space station construction mission plan, the 1 1 mission will be carried out this year and next, including three space station module launches, four cargo spacecraft launches and four manned spacecraft launches. In 2022, the on-orbit construction of the space station will be completed and the National Space Laboratory will be built. After that, the space station will enter the application development stage. Every task is a "big project", with the hard work and wisdom of thousands of people behind it. In order to ensure the smooth implementation of the task, all units in each system are fully prepared to meet the future with excellent results.
Deep in the Badain Jaran desert, the vertical assembly test workshop of Jiuquan Satellite Launch Center is brightly lit and crowded, and the staff walks between the spacecraft arrow and the test instrument, running around day and night.
The aerospace industry has been described as "a thousand people with one arrow", and any link is related to success or failure, and no one can treat it lightly. As the home port for China astronauts to enter and leave space, X Satellite Launch Center has built a safe "ladder" with meticulous attitude.
"The hoisting team of dozens of people cooperates with the task, and every step of operation can't go wrong, and the hoisting and docking error is even smaller. Each product can only be hoisted and landed successfully once, and there is no chance of turning over and no mistakes. When hoisting the docking rocket, dozens of bolts in a circle should be aligned and connected at one time. " Shi Chuangfeng, the base staff, undertakes the lifting work. In order to be fast and steady, he invented his own training method, tied a covered electrode to the hook and operated a crane to insert beer bottles from high altitude. At the end of the exercise, he and his colleagues waved the heavy crane iron arm as flexibly as they waved their own arms.
Thousands of flights, safety first. Taking the life safety of astronauts as the bottom line, the Shenzhou-13 manned spacecraft team of China Academy of Space Technology has made plans and measures to ensure the safety of astronauts at all stages of launch, flight, docking, docking and return of Shenzhou-13, and will also start the emergency rescue mission mode of manned spacecraft for the first time to fully ensure the safety of astronauts going back and forth between heaven and earth.
Only by truly understanding where the starting point and road of manned spaceflight project are, can we draw strength from history and make better progress.
