500 words after reading "Flying to Space Port"

What do you feel after reading a book? It is necessary to write a review about what you have gained. Is it impossible to write without a clue? The following are 500 words I collected after reading Fly to Space Port. Welcome to read, I hope you will like it.

Recently, I read the book "Flying to a Space Port" and realized that the development of China's space industry is hard-won, and I have many feelings.

From the first manned space flight in Shenzhou 5 to the launch of Shenzhou-12 and the successful docking with Tiangong-1, China went deep into space and achieved a breakthrough; From Dongfanghong-1 to Beidou satellite covering the whole world, China astronauts once again said "no" to the impossible, and let China satellite serve thousands of households.

However, behind China's nine-day dream of landing on the moon, it is not easy.

At first, China, the hometown of rockets, wanted to put its Long March III rocket into the market, which caused a short-lived "China rocket fever" around the world. But behind this upsurge is the commercial competition between the United States and France, and these two space powers compete for the business opportunities behind it. China's original plan was disrupted and was in a dilemma.

Finally, under the lobbying of China astronauts, the United States agreed to sign a contract and sell "Yaxing" to China for launch. However, the request of the United States is also very difficult, requiring Xichang Launch Center to build an international standard satellite test factory with a class of 100,000! There is no precedent in China, and there is no ready-made information. Time is tight and the risk is great. All kinds of pressures are like mountains on the shoulders of astronauts. What shall we do? Design it ourselves! In the voice of outside doubts, the satellite test plant began to be built. 50 days design, rapid construction, its cleanliness far exceeds the standard of100000, and the temperature control accuracy far exceeds the agreement! China's speed and China's strength have amazed foreign space experts!

After "Yaxing" successfully entered the factory, American experts kept putting forward a new round of requirements to the Chinese side: the factory should not be cut off for 24 hours; The phone is always on; Traveling to Xichang by bike; Climbing mountains to keep healthy ... Facing all kinds of "tests" from the United States, China astronauts responded reasonably: take off their military uniforms, put on suits and ties, speak concisely, and don't drag their feet ... So far, the United States has changed its attitude towards China and admired China astronauts even more!

From the arrival of "Yaxing" to the successful launch, astronauts have been overcoming difficulties: fighting against nature, weather and unexpected situations ... They have overcome natural disasters, overcome external doubts and written space history with their super abilities, excellent technology and cool heads.

Times are developing, so is China's space industry, and China's science and technology are going deep into space. I believe that in the future, China Aerospace will become China's space sword!
