1. China's first artificial satellite, Dongfanghong-1.
On April 24th, 0970, at 2 1 35, Dongfanghong 1 satellite was launched by the Long March 1 carrier rocket, and China's long March in space began.
After the "Dongfanghong 1" satellite was put into orbit, it operated well and all kinds of instruments worked normally. The short-wave radio transmitter on the satellite plays the music and telemetry signal of "Dongfanghong" circularly, and the sound of the music is clear and loud. Cycle once every minute. First, the music "Dongfanghong" is played twice in a row for 40 seconds. After an interval of 5 seconds, the telemetry signal broadcasts 10 second, and enters another cycle after an interval of 5 seconds. The telemetry instrument on the artificial earth satellite keeps sending back all kinds of data. When the satellite passes through major cities, people learn about the situation from the radio and newspapers. As soon as this time approaches, people can't help but run outdoors and look at their satellites excitedly.
The successful launch of the "Dongfanghong 1" satellite is the first major breakthrough in China's space technology, making China the fifth country in the world to independently develop and launch spacecraft after the Soviet Union, the United States, France and Japan.
2. Why should China develop manned space flight?
Why China should develop manned space flight has long attracted much attention. Manned space flight is the most representative high-tech project in contemporary times. Carrying out manned spaceflight project has great practical significance and far-reaching influence on a country's politics, economy, science and technology, national defense and personnel training.
Manned space flight is an important symbol to measure a country's comprehensive national strength. In today's world, nothing can fully demonstrate a country's comprehensive national strength than manned space flight. Without highly developed scientific technology and research capabilities, a solid economic foundation and strong economic capabilities, it is impossible for any country to carry out manned spaceflight projects. Therefore, China's manned spaceflight project can enhance China's international status and prestige, enhance the self-confidence and pride of the Chinese nation, fully display China's comprehensive national strength, and promote economic development and scientific and technological progress.
Manned space flight has a strong traction for the development of science and technology. Manned space technology concentrates the latest achievements of contemporary scientific and technological development and is a master of cutting-edge technologies in various disciplines and technical fields. While applying these existing technological achievements, manned space flight puts forward new and higher requirements for these scientific and technological fields in order to promote the development of manned space technology and the realization of manned space flight. The efforts and technical achievements made to achieve these goals have objectively promoted the development of these disciplines. Therefore, manned space flight has greatly promoted the development of science and technology.
Manned space flight plays an important role in promoting economic construction. At present, although the direct economic benefits of manned space flight are not obvious, many new technologies and products developed by manned space flight activities have played an important role in promoting the technological transformation of traditional industries, improving economic benefits and promoting economic construction, resulting in extensive social and economic benefits. At the same time, when people go into space, they can use the space environment to carry out a series of experiments. These experiments will not only obtain new materials that cannot be produced and processed under ground conditions, but also obtain new technologies and methods. These technologies and methods will have a positive impact on promoting economic construction and improving efficiency and economic benefits.
Manned spaceflight can promote the deepening of scientific research. Manned spacecraft provides an effective carrier for scientists to carry out scientific research. Observing the earth from space can help us understand the structure of the earth more deeply, find out its resources, predict natural disasters such as earthquakes, floods, hurricanes and volcanic eruptions, and protect people's lives and property. American astronauts made 146 earth observations in the space laboratory, including crop growth, the spread of pests and diseases, forest fires, snow melting and so on. By providing observation data to experts from relevant departments, we can study and evaluate geology, geography, agriculture, biology, hydrology, environmental pollution and mineral deposits.
China's manned space program is divided into three steps.
According to the development plan of China's space industry, China's manned space program is implemented in three steps.
The first step is to launch unmanned and manned spacecraft, send astronauts safely into low-earth orbit, conduct earth observation and scientific experiments, and return astronauts safely to the ground. With the safe return of China's first astronaut Yang Liwei in June 65438+1October 65438+June 2003, the first step of China's manned spaceflight project has been completed.
The second step is to continue to break through the basic technology of manned space flight: multi-person and multi-day flight, astronauts walking out of the cabin, and completing the rendezvous and docking of the spacecraft and the space capsule. On the basis of breaking through these technologies, a short-term manned space laboratory will be launched to build a complete space engineering system. The successful launch of Shenzhou VI marks the beginning of the second step of China's manned spaceflight project. The next step in China's manned space flight will be for astronauts to leave the cabin and walk in space.
The third step is to establish a permanent space laboratory and space engineering system in China, where astronauts and scientists can travel between the Earth and the space station and conduct large-scale space science experiments.
I hope it helps you.
