On October 29, long Jianhua, lisep, Zhao Hanyuan and others watched TV in the small meeting room to watch the space trip of old green, the first man in the world to fly in space for the second time. He was the first astronaut in the United States. He made his first flight around the earth in February 1962, with an interval of 36 years.


    This is a live broadcast. As a part of people who are determined to live in space, they all want to see "experience" once and worship the hero old green.


    350 miles above Hawaii, old green said to the camera, "gravity is zero! It feels great! "


    After these two sentences, he turned and floated away. The commentator seemed to find something, "Wow, old Green''s face is swollen. He volunteered to use his body as an experiment on the effect of space flight on aging. We should praise old green. "


    "Old green applied to participate in the Apollo program and the Challenger spaceflight, and was approved. However, he always adhered to his strict living system, running, weightlifting and swimming every day..."


    Long Jianhua said with a smile, "it seems that we still need a good body if we want to travel in space. How many of us can exercise like him? Let me flaunt it first. I exercise every day. Although I don''t swim every day, I swim once a week. "


    In my heart, I made a decision: build a swimming pool in No. 7 hospital and swim a few kilometers every day.


    Lisep shrugged. "I may not catch up with our space trip. I''m in my fifties and don''t like exercise. Of course, if we can step into space in 20 years, I can still travel once. It was only 73 at that time, younger than old Green''s 77. "


    Long Jianhua smiled, "lisep, you are the Dean, and the progress is mainly in your hands; Therefore, what you just said is purely shirking responsibility. "


    Daisy smiled and said, "I agree with Professor long. Lisep, don''t forget that you are also a member of the project, responsible for the supply of various semiconductor components. If you don''t work hard, even if we work hard at body design and engine design, we can''t take off. I want to make sure that you don''t exercise because you don''t want to go to space? "


    Zhao Hanyuan glanced at several people. "I can responsibly tell you that our first rocket engine has completed the test from parts to the whole machine three days ago. The data show that this engine is successful. As long as the rest of the design is completed, we can start the full arrow test. "


    The news surprised everyone. In less than two years, the engine has come to this step?


    After the test data came out, he told long Jianhua the situation for the first time, but most of the people present didn''t know.


    Daisy was a little depressed. "It may take some time for the body part, and there are difficulties in the selection of materials and processes in some places."


    Then he cheered up, "but we will finish the final draft soon. It won''t take more than a month. "


    Long Jianhua occasionally went to them and saw that they were constantly calculating and experimenting. They worked very hard and didn''t put pressure on her. "We are latecomers. We have learned a painful lesson ahead. For such things, we can''t blindly pursue progress. Everything should be based on safety. "


    Lisep nodded, "we have received two satellite launch missions from five countries, and the time is relatively urgent; However, everything should be based on safety. There is no security guarantee. If we fail, we have to pay compensation. People will not continue to give us orders. "


    Long Jianhua smiled, "don''t talk so long first. The food should be eaten mouth by mouth and the road should be walked step by step. In this field, we are new entrants and primary school students. We should take every step in a down-to-earth manner and can''t wrestle. "


    After reading old Green''s speech, the party broke up.


    When lisep stayed, he said with a smile, "Long Dong, our research institute and group have a good reputation. If we promise to launch satellites next year, we can receive more launch missions."


    Long Jianhua shook his head, "there''s no way. We just want to accumulate some data, increase some experience and recover some investment. "


    "Our goal is still space travel, flying to the moon, flying to Mars, and building a base there."


    Lisep laughed, "I''m looking forward to this goal now. On October 8, the Hubble Space Telescope discovered galaxies that may have existed for 13 billion years, which excited me for a while. "


    "If I can establish bases on the moon and Mars, make another breakthrough in aerospace technology and travel to distant planets, it is not impossible; Maybe you can jump directly to that galaxy. "


    As a scientist, the first thing is to dare to think, and then turn ideas into actions. Of course, this dare to think, not wishful thinking, need to have a scientific basis, or in line with the laws of nature.


    However, long Jianhua did not expect lisep to think so. In his impression, he has never said such an idea in other fields


    When having dinner at home, Zheng Yu said, "Dad, a 77 year old grandfather in the United States traveled to space for the second time today."


    Long Jianhua turned to look at him, "and then?"


    Zheng Yu responded, "many of our classmates want to be astronauts. They all wrote to the United States, hoping to travel in space by American Rockets next time. I wrote it, too. "


    Long Jianhua touched his head and said with a smile, "what are you writing to the United States for? Why don''t you write to me? "


    Liu Zhifei knocked Zhengyu''s head with chopsticks, "your father, they are studying rockets and will organize space travel in the future. Didn''t you say not to mine lunar minerals? "


    Qinglan said with a smile, "my brother, now he has become a fool. He has forgotten such things."


    Zheng Yu blushed, "I know Dad, they are studying, but they have gone to heaven in the United States. Who knows when they can go to heaven?"


    Long Jianhua nodded, "from this point of view, your idea is correct; Their has been made clear, and ours is only expectation. But you don''t believe in us or our wisdom. "


    Liu Zhifei gave him a white look and hummed, "in expectation and reality, how many people will choose expectation?"


    Zhengyu hurriedly said, "Dad, mom, things are not so complicated. First of all, people may not agree with us; Secondly, if we travel in space first, the United States will not go there. "


    Qinglan turned to look at him, "seize all opportunities. Brother, you have to go. "


    Liu Zhifei asked, "brother Hua, it seems that this project has been established for a long time. How is it going?"


    Long Jianhua responded, "the test of a single engine has been completed and achieved the expected results."


    Zheng Yu swallowed the rice in his mouth, "it will take a long time to go to heaven."


    Today''s children don''t know how to understand so much.
