1. Understanding after Shenzhou 13' s return to Earth
The "seamless connection" between Shenzhou 12 and Shenzhou 13, first of all, is to care for astronauts' humanity and protect shenzhou spaceship.
This is not only the replacement of spacecraft, but also allows a group of astronauts to have a rest after performing the tasks at this stage and replace a new group of astronauts to perform new tasks, so as to maintain the state and better complete the tasks. But also can find and solve the existing problems more efficiently.
Secondly, this is also the performance of China's further development in the aerospace field. China's aerospace industry is developing vigorously. We should seize the time to build our space station in an all-round way and break the technical restrictions imposed on us by foreign countries. China has achieved great improvement in its international status by relying on the aerospace industry, and we can't stop.
Finally, this is also telling the world that China's space journey will not stop here. "Holding the red flag high to show its national prestige, accompanying the stars to look around for thousands of miles is short", and we must make great strides forward!
2. What I realized after Shenzhou XIII returned to Earth
With the successful return of Shenzhou XIII, the doubts in my heart gradually subsided, and the big stone in my heart finally fell to the ground.
China's manned space program has achieved fruitful results. On the road of "chasing dreams", every time is a brand-new journey, and every time is an unprecedented challenge. Of course, the unprecedented challenge difficulty has also created an unprecedented height. Mr. Lu Xun once said: "In fact, there is no road on the ground, and more people walk, so it becomes a road." The road is made by two feet and is developed step by step. Since the development of China's space industry in 1956, self-reliance and independent innovation have been consistent in the development and the core competitiveness to promote the development of space industry. It is inevitable that detours will be necessary to take the road that the predecessors have not taken, and setbacks will be inevitable to break through the barriers that the predecessors have not. Only by being a pioneer can you become a pioneer. Only by daring to break through can you break through a new world and seize the "new highland".
Great cause breeds great spirit. Looking back at the development history of space industry, whether it is the successful launch of "Dongfanghong-1" or the great achievement of Shenzhou manned spaceflight project; Whether the Beidou satellite navigation system is completed in an all-round way or "Chang 'e" flying to the moon and "Tian Wen" exploring fire, from bold ideas to successful practice, China's space strength that keeps pace with the times is demonstrated. China's space industry has gone from a difficult start to a arduous journey to brilliant achievements, leaving behind China and China in the vast space, and China spirit and China's strength in the development of space industry. This spirit and strength will surely lead 1.4 billion Chinese sons and daughters to struggle with one heart and one mind, stir up great power, forge ahead in a new journey and dream of a new era.
3. Reflections on Shenzhou XIII's return to Earth
I heard that Shenzhou XIII has returned and gave us a live broadcast today.
In the live broadcast, we were told many scientific principles. For example, put a bottle full of water on the table, then put the ping-pong ball in it, and plunge it in with a straw. The ping-pong ball stuck in it instead of ejecting it, which is amazing. Then he left the bottle full of water uncovered. Instead of spilling it, it floated without leaking a drop of water.
There is also a magnifying glass placed on the table, and then the water is squeezed up with a water squeezing bag. The squeezed water is not spilled, but solidified on it as if it lives on it. In this way, it becomes a big crystal ball. Then I made a circle on it, and you can see two astronauts on the circle, one is straight and the other is upside down, which is amazing.
After watching this live broadcast, I feel the magic of science and the strength of my motherland, so I will study hard, so that I can contribute to my motherland.
4. Reflections on Shenzhou XIII's return to Earth
At 9: 56 on April 16th, 222, the Shenzhou XIII spacecraft, which had been traveling in space for half a year, landed safely at the Dongfeng landing site, and three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, who were on a business trip in space, left the warehouse safely and smoothly and returned to the embrace of the earth.
When I saw the mother who picked the stars come back! Wang Yaping, who smiled sweetly and waved happily in front of the camera, smiled and gave her daughter "Star" greeted with a red dress. My heart was excited, which was for her daughter and the people of the motherland.
By watching the live broadcast of Shenzhou XIII returning to Earth, I realized that China's space industry has left China in the vast space, contributed China's strength to human science and left China spirit in human space. As the "flowers" of the motherland, we should strive to learn scientific knowledge well and be good at using it, turn the great space spirit into the internal driving force of our study, grasp the baton of the scientific development of the motherland, undertake our mission, and make our own contribution to the development of the motherland and the progress of mankind.
5. Reflections on Shenzhou XIII's return to Earth
Today, April 16th, the 16th day of the third lunar month, coincides with a good day on Saturday, and Shenzhou XIII successfully returned home. Three astronauts who spent six months on business in space returned to Earth successfully.
Although the life of astronauts during their flight is rich and varied, the actual range of activities is greatly limited. In addition to ensuring the normal operation of instruments, it is a challenge not only to the body but also to the mind in an environment where gravity is not felt for a long time.
But they kept their faith, overcame many difficulties, and turned the incredible things into reality, setting a new record for continuous in-orbit flight, which will be a big step forward for China's space flight. I believe that in the future, there will be more China marks in the vast universe.
6. Reflections on the return of Shenzhou XIII to Earth
Today, my classmates and I watched the live lecture of Shenzhou XIII in the classroom. Among them, I think the most profound thing is that Aunt Wang Yaping took something like a magnifying glass, then took out the water bag and squeezed the water in the water bag into the round frame. Aunt Wang Yaping said to turn it into a big water polo, but she kept adding water to something like a magnifying glass, and the big water polo slowly swelled up. She also put the pink floret made by herself and her daughter in the water, and the floret opened instantly. Then Aunt Wang Yaping squeezed something full of air into the water polo, but through the air in the water polo, she saw that Aunt Wang Yaping was facing us, but from the water polo, Aunt Wang Yaping was the other way around.
Another experiment that impressed me deeply was that Aunt Wang Yaping put a ping-pong ball in a glass of water and held it with chopsticks for a few seconds, but the ping-pong ball didn't float. Aunt Wang Yaping put the uncovered cup in the air, but the water and ping-pong ball in the cup didn't pour out. This is really amazing.
Through this class, I learned a lot of scientific truths, further understood the mysteries of space and interesting and magical spaceships, and understood that science is everywhere and the motherland is powerful. I must study hard and make progress every day in the future, so that our motherland will become more and more developed in science and technology.
7. Understanding after Shenzhou XIII returned to Earth
Shenzhou XIII returned to Earth and brought us a live broadcast.
I learned many useful scientific tricks in the live broadcast.
In space, put a cup full of water on the table, then put the ping-pong ball in it and stick it into the water with a straw. Ping-pong is really amazing. Instead of popping out, it is fixed. When the cup filled with water is poured down, the water and ball in the cup are not poured out, but not a drop is leaked.
Another scientific coup is to put a magnifying glass on the table, and then squeeze water from a water squeezing bag. The squeezed water did not spill, but it solidified on it, like a big crystal. Then a circle is formed on it, and two astronauts can be seen on the circle, one is straight and the other is upside down, which is very magical.
After watching this interesting video, I feel the magic of science. We should study hard and strive to be a scientist.
8. Reflections on the return of Shenzhou XIII to Earth
Many years ago, China's space industry officially started, and the success of each space launch mission is a true manifestation of China's continuous efforts and struggles.
In the future, with the continuous development of a new generation of Long March series launch vehicles, China's launch vehicle capability will once again achieve a new leap: the development of a new generation of medium-sized launch vehicles such as Long March 6 A, Long March 7 A and Long March 8 is being carried out as planned to realize the "upgrading" of the launch vehicles as a whole; The Long March 5 rocket will carry out several important launch missions successively, supporting the steady implementation of major engineering projects such as the lunar sampling return in the third phase of China's lunar exploration, the launch of the Mars probe and the construction of the core cabin of the space station; The heavy launch vehicle is expected to make its first flight in 23, which will make 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 repeated use, from single space transportation to the combination of space transportation and space operation. It is not difficult to imagine that with the continuous enhancement of China's space comprehensive strength, the Long March series of launch vehicles will surely carry China's space dream, condense the struggle spirit of China astronauts, fly into space again and again, and start the "New Long March" of China's space industry.
Looking up at the starry sky, the journey is long. 3 launches are only the first step of the "Long March" of China's space industry, and there are 5, 1, 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 bigger "space dream" and leave a more wonderful China mark in the vast universe.
9. Thoughts after Shenzhou XIII returned to Earth
At 9: 56 on April 16th, 222, with a loud bang, several meters of smoke rose on the Gobi Desert, and the Shenzhou XIII return capsule successfully landed in the scheduled area! The whole land of China is cheering, and I jumped up in front of the TV. The space "business trip trio" finally triumphed safely!
When I saw three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, coming out of the cabin in turn with victorious smiles and waving to everyone, my previous nervousness was swept away, and my heart was filled with pride and excitement. From a one-day trip in space in 23 to a six-month trip in space by a "business trip trio" of 2XX; After returning from Shenzhou XII, it was compressed to 7 on Shenzhou XIII after more than 2 hours. Five hours, the leap of "hands can pick stars" is an ordinary and great dream of several generations of astronauts, and it is also a dream of the great motherland in the blue sky.
Under the guidance of powerful Chinese power, China people who look up at the starry sky and are down-to-earth will surely write different kinds of flowers on the vicissitudes of China.
1. Reflections on the return of Shenzhou XIII to Earth
Following the glorious return of Shenzhou XII manned spacecraft, Shenzhou XIII manned spacecraft successfully lifted off with three astronauts in the eyes of all people, and China people's dream of chasing the stars and the sea will take another big step forward and set a brand-new milestone for "realizing their dreams for nine days".
once in a thousand years. From The goddess patching the sky and the Goddess Chang'e flying to the moon to Sina and Kongming Lantern, we saw romantic and magnificent imagination from flying dreams, and also experienced a breakthrough from zero to one. "It's a long way to go in Xiu Yuan, and I will go up and down for it" is our insistence on our dreams and our initial intention of struggling hard for them. From romantic imagination to simple exploration tools, it is a step for China people to measure their dreams, and it is a vivid footnote for China people to dare to think and do well. A nation needs people who look up at the starry sky, who are the eyes to explore and discover new things; A nation also needs down-to-earth hard work, which is the way to turn imagination into results.
The Milky Way is rolling into dreams. The Chinese nation is a nation that is good at sublimating emotional romance into scientific practice, from "When did the Jade Rabbit go to the Moon Palace, and there was no trace of smashing medicine at night" to "Chang 'e III" reaching the surface of the moon; The global satellite navigation system from "the setting sun of Kuifu Gucheng, depending on Beidou Wangjinghua" to "Beidou-3" was officially completed and opened. In the poems full of emotion, we find the poetic and romantic expression of flying dreams. From the appearance of great powers, we find the spiritual inheritance and continuous struggle between generations, which is the romantic continuation of the aerospace spirit.
Great cause breeds great spirit, and great spirit promotes great cause. From Wang Yaping, who doesn't want a man, what we see is the tenacious spirit that can bear hardships; From Ye Guanfu, who is frequently mobilized and reset from scratch, what we see is the fighting spirit that is particularly capable of fighting; From Wang Xiji, who has made many career changes to meet the needs of the country and completed many pioneering work in the fields of sounding rockets, recoverable satellites and manned space flight, what we see is the spirit of exploration that is particularly capable of tackling key problems; From Qian Xuesen, who cherished the motherland, gave up foreign preferential treatment, broke through many difficulties, and boarded the returning ship, what we saw was the selfless spirit of special dedication ...
The stars don't ask the passers-by, and time pays off. On the journey of the great rejuvenation of the Chinese nation, generations of scientists have devoted themselves to the aerospace industry without stopping, not afraid of difficulties and without hesitation. With their consistent self-reliance and independent innovation, they have struggled all the way, worked hard in silence, and turned the scientific "desert" into an "oasis" in the romantic persistence of generations of astronauts, creating numerous achievements in the aerospace industry and leaving us behind.
A steady stream flows into a river; The journey is long, only struggle. A "flying history" of China people is also a history of struggle. Only by being down-to-earth can we irrigate the "romantic fruit" and go further and further in bravely climbing the peak. We should break the ultimate meaning of "romance" from the "aerospace spirit", temper our courage to forge ahead, learn from our determination to overcome difficulties and make contributions to the realization of the great rejuvenation of the Chinese dream.
