1On April 24th, 970, China launched the Dongfanghong-1 satellite with the Long March-1 carrier rocket, which marked that China became the fifth country to launch satellites independently. 1975165438+1October 26th, China launched its first recoverable satellite, which is the third country to master recoverable satellite after the United States and the Soviet Union. On June 65438+1October 65438+May, 2003, China's Shenzhou 5 was launched, marking China's becoming a space power. Tiangong-1 has been docked one after another, forming a tripartite confrontation between China, the United States and Russia in space. The remarkable achievements made by China Aerospace are attributed to a team that is not afraid of difficulties and hardships. They are the backbone of China. I believe that under the guidance of this spirit, our motherland will become stronger and stronger.

The story of China's space hero 100 words.
Story 1: Zhai Zhigang, Han nationality, from Longjiang County, Heilongjiang Province. Selected as the first manned astronaut echelon in China and the Shenzhou-6 manned space flight crew echelon. Zhai Zhigang, with thick eyebrows and big eyes, is handsome and handsome. When he was an Air Force pilot, he became a "model" on the cover of China Air Force magazine. However, from Shenzhou V to Shenzhou VI, he was selected into the echelon twice, but he missed Tian Fei twice. Zhai Zhigang can break through his own limits again and again and finally succeed in flying, to a certain extent, because of his poor life experience as a child. Zhai Zhigang was born in the rural area of Longjiang County, Heilongjiang Province on the Nenjiang Plain. Despite the difficulties of life, illiterate mothers have high hopes: selling iron in the pot and letting their children study. In that poor village, it is rare to train all six children above high school. My mother sells fried melon seeds for Zhai Zhigang to finish primary school and junior high school. It is unbearable for Zhai Zhigang, who has just been admitted to high school, to see his mother, who is nearly sixty years old, get up early every day to sell melon seeds in the street. Zhai Zhigang loves his mother dearly and wants to drop out of school and go home to help her work. The mother who has always been kind is angry: "Mom can't read and can't speak anything, but find a reason, you must study!" " 1June, 1985, Flight Academy enrolled students, and Zhai Zhigang was successfully admitted. The day before I left, my mother made an exception and didn't go out to sell melon seeds. She borrowed money from her neighbor in 20 yuan and bought a travelling bag for her son. She wanted to help him pack, but there was nothing to fill at home. The old man wept silently at the empty bag. Finally, the mother fried a pot of melon seeds for her son, chose big and full ones one by one and put them in the travel bag. Mother took 5 yuan money out of her pocket and stuffed it into her son's hand. At that time, 5 yuan needed her mother to sell melon seeds outside for a few days to earn money. Zhai Zhigang couldn't help feeling sad any longer, and cried with his white-haired mother in his arms. After arriving at school, the monthly allowance is 12 yuan. Zhai Zhigang only keeps two yuan, and the rest is sent to his mother. Knowing that his mother likes to drink sugar water, he brought sugar and milk powder to his mother. After becoming an astronaut, Zhai Zhigang went home to visit relatives only a handful of times. Before leaving once, Zhai Zhigang left a small box made of paper shell to his mother. Mom opened it and found that it was full of coins, more than 200 yuan. At that time, the whole family cried. 165438+2004 1 October 20th, after the successful flight in Shenzhou 5 1 year1month, Zhai Zhigang's mother who loved him the most and cared about him the most died. Zhai Zhigang didn't see his mother for the last time because he had a task. When he hurried home and faced his mother's tombstone, the strong northeast man burst into tears. Story 2: Jing Haipeng's hometown is Yuncheng, the hometown of Guan Gong. In the fifth grade, Xiao Haipeng fell in love with playing basketball. When his family couldn't afford sportswear, his father bought him a vest with seagulls and the sea painted on the front and a big "5" on the back. Mother cut him a pair of shorts with her own blue cloth. Haipeng, who appeared on the court in this suit, was called "Seagull 5" by everyone. Because he is short, he can't play the main force, and he won't give up. Finally, he became the basketball star of the team with his accurate shooting skills, and now he is the "steel striker" of the astronaut basketball team. "Being a' steel shooter' depends on' stubborn temper'." Jing Haipeng said that by playing basketball, he understood a truth: As long as you work hard, no one is worse than anyone else. 1984 The Air Force recruited pilots in Yuncheng, but Jing Haipeng was unsuccessful. Jing Haipeng's sister, Jing Yanfang, recalled that at that time, it was probably because she studied too long and was overworked, and her eldest brother's eyes were a little bloodshot, so she didn't get in. A bigger blow followed-his father planned to never let him go to school again. "I also want him to go to school, but at that time, all three children at home had to go to school, and the family could not maintain it at all." Jing Haipeng's father, Jing Kaoxi, recalled that Xiao Haipeng didn't eat for three days and nights after learning that he could no longer go to school. Seeing the sad look of Haipeng, the distressed parents finally decided to let their son study again 1 year. After studying hard for 1 year, Jing Haipeng was successfully admitted to the Aviation School. Jing Haipeng is an excellent flight student in the Flight Academy. There is an event in the training-swimming. Swim 50 meters to pass, or you may be eliminated. Jing Haipeng is the "landlubber" in the north. He has never been in the water since he was a child. When training, you will either jump blindly or choke on water, and you will not be able to swim near the exam. On the day of the exam, Jing Haipeng bit his lip and went into the water from deep water. I don't know what magical power inspired him, but he swam 50 meters to the other side. His comrades applauded him, and he swam back to the deep water area. When he reached the pool, he felt that his physical strength was still very good, and he turned to a new goal. As a result, he can not only swim overnight, but also swim 200 meters in a row, with excellent results! The leader of the student team announced the "reward" on the spot, which was his first reward after joining the army and the first reward after the whole squadron entered school. Afterwards, someone asked him, what is the driving force of 200 meters upstream in one night? He replied: "No matter what you do, you must have faith and never give up!" " "Story 3: 1966 On September 16th of the lunar calendar, a baby boy was born in an ordinary farmer's home in Dongsheng Village, Hongxing Township, Yi 'an County, Heilongjiang Province, and his father Liu Zhisheng named him Liu Boming. Liu Boming has six brothers and sisters, and he is the second in the family. 1983, when Liu Boming was admitted to Yi 'an No.1 Middle School to attend high school, his family had to provide five children with schooling at the same time, and his father, who made a living by farming, was already deeply tired. Knowing the difficulties at home, Liu Boming decided not to live on campus like other students, but to run away from school. My father gritted his teeth and spent more than 100 yuan to buy him a second-hand "Baishan" bike for him to go to and from school. The school is close to home 10 km, and there are potholed dirt roads everywhere. It's hard to walk when the weather is fine, but when it rains, it turns into black mud, and it's hard to leave. The road is icy and slippery in winter. Liu Zhisheng said that in the third year of high school, Liu Boming got up at three or four o'clock every day. It was dark when he left, and it was dark when he went home. There was no sun at both ends. " This is very sinful, but there is no way, this is the condition at home. "Zhang Fulin, the head teacher of grade three in Liu Boming High School and now the deputy director of the Education Bureau of Yi 'an County, said that Yi 'an would be very cold in winter. Even if it doesn't snow, Liu Boming rides to school with frost on his face, neck and body, and his clothes are all wet.
