In 1950s and 1960s, China conducted a series of animal experiments before manned space flight. 1959, China successfully carried two mice on high-altitude rockets for flight experiments. Since then, many rocket experiments have been carried out, carrying different kinds of animals, such as mice, dogs and rabbits. To study their antagonistic ability in the cosmic environment.
1964, in China, for the first time, animals were used for biological satellite experiments, and an artificial satellite named "Dongfanghong-1" was adopted. The mission carried two mice, fruit fly eggs, silkworm eggs and other biological loads into the space environment to study their physiological and biochemical changes under the conditions of gravity, radiation and microgravity.
Since then, China has carried out many animal carrying experiments. In a series of manned space missions in 2005 and 2006, mice were successfully carried to study their behavior, physiology and biochemical characteristics in space. These animal experiments provide valuable data for China's space science research, and help to provide experience and basis for future space exploration and manned spaceflight.
At the same time, it is also of great scientific significance to understand the influence of space environment on living things and the adaptability of human beings in space. It needs to be clear that these experiments will strictly follow ethical principles and animal welfare norms to ensure the safety and welfare of animals. Generally speaking, China has carried out animal carrying experiments in the process of space development to explore the adaptability and physiological changes of animals in the space environment. These experiments have made important contributions to space science research in China.
China was the first man to launch a rocket into space.
The first person to launch a China rocket into space was Yang Liwei. He is a member of the China Astronaut Team. He successfully entered space on the Shenzhou 5 spacecraft in June 65438+1October 65438+May 2003. This marks that China has become the third country to carry out manned space flight independently after Russia (former Soviet Union) and the United States. Yang Liwei carried out a series of scientific experiments and missions in space, flying for 2 1 hour for 23 minutes.
His space trip is widely regarded as a milestone of China's space program and has made great contributions to the development of China's space industry. Yang Liwei's success has made China's space industry get more attention and international recognition, paving the way for a series of manned space missions and the construction of China's space station.
