1. China's first artificial satellite - Dongfanghong 1
At 21:35 on April 24, 1970, the "Dongfanghong 1" satellite was launched by the "Long March 1" carrier rocket. China’s long march into space began.
After the "Dongfanghong-1" satellite entered orbit, it was operating in good condition and various instruments were working normally. The shortwave radio transmitter on the satellite broadcasts the music "The East Is Red" and telemetry signals in a loop, and the music sounds clear and loud. It loops once every minute. First, it broadcasts the music "The East is Red" twice continuously for 40 seconds. After an interval of 5 seconds, it broadcasts the telemetry signal for 10 seconds, and then enters another cycle after another 5 seconds interval. Telemetry instruments on artificial earth satellites continuously send back a variety of data. People get information from radio and newspapers about when satellites will pass over major cities. As the time approaches, people can't help but go outside and watch their country's satellites excitedly.
The successful launch of the "Dongfanghong 1" satellite is the first major breakthrough in my country's aerospace technology, making our country the fifth country in the world to be able to independently develop and launch satellites after the Soviet Union, the United States, France and Japan. Spacecraft country.
2． Why China wants to develop manned spaceflight
Why China wants to develop manned spaceflight has long been a matter of concern. Manned spaceflight is the most representative high-tech project of our time. The implementation of the manned space project has great practical significance and far-reaching impact on many aspects such as a country's politics, economy, science and technology, national defense and personnel training.
Manned spaceflight is an important indicator of a country’s comprehensive national strength. In today's world, nothing can fully demonstrate a country's comprehensive national strength than manned spaceflight. Without highly developed science and technology and scientific research capabilities, without a solid economic foundation and strong economic capabilities, it is impossible for any country to implement a manned space project. Therefore, our country's implementation of manned space projects can improve our country's international status and international prestige, enhance the self-confidence and pride of the Chinese nation, fully demonstrate our country's comprehensive national strength, and promote economic development and scientific and technological progress.
Manned spaceflight has a strong pulling effect on the development of science and technology. Manned space technology embodies the latest achievements in the development of contemporary science and technology. It is the culmination of cutting-edge technologies in multiple disciplines and technical fields. While applying these existing technological achievements, manned space technology also promotes the development of manned space technology. The development and realization of manned spaceflight have put forward new and higher requirements for these scientific and technological fields. The efforts made and the technical achievements achieved to achieve these goals have objectively promoted the forward development of these disciplines. Therefore, manned spaceflight plays a huge role in promoting 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 spaceflight are not obvious yet, many new technologies and new products developed by manned spaceflight activities have played an important role in driving the technological transformation of traditional industries, improving economic benefits, and promoting economic construction. , producing extensive social and economic benefits. At the same time, when people go to space, they can use the space environment to conduct a series of experiments. These experiments will not only obtain new materials that cannot be produced and processed under ground conditions, but also new processes and methods. These processes and methods will have a positive impact on promoting economic construction, improving efficiency and economic benefits.
Manned spaceflight can promote the in-depth scientific research work. Manned spacecraft provide an effective carrier for scientists to conduct scientific research. Observing the earth from space can provide a deeper understanding of the earth's structure, explore the earth's resources, predict earthquakes, floods, hurricanes, volcanic eruptions and other natural disasters, and protect people's lives and property. U.S. astronauts conducted 146 Earth observations in the space laboratory, including the growth of crops, the spread of pests and diseases, forest fires, and the melting of snow cover. By providing the observed data to experts from relevant departments, research and assessment on geology, geography, agriculture, biology, hydrology, environmental pollution and mineral deposits can be carried out.
3. China's manned space program will be implemented in three steps
According to China's space industry development plan, China's manned space program will be implemented in three steps.
The first step is to launch unmanned and manned spacecraft, safely send astronauts into low-Earth orbit, conduct earth observations and scientific experiments, and return astronauts to the ground safely. With the safe return of my country's first astronaut Yang Liwei on October 16, 2003, the first step of China's manned spaceflight project has been completed.
The second step is to continue to break through the basic technologies of manned spaceflight: multi-person multi-day flights, astronauts leaving the cabin to walk in space, and completing the rendezvous and docking of the spacecraft and the space capsule. On the basis of breakthroughs in these technologies, short-term manned space laboratories will be launched and a complete supporting space engineering system will be built. The successful launch of "Shenzhou 6" marks the start of the second step of China's manned spaceflight project. The next step for China's manned spaceflight will be for astronauts to leave the cabin and conduct space walks.
The third step is to establish a permanent space laboratory and build China's space engineering system. Astronauts and scientists can travel between the earth and the space station to conduct relatively large-scale space science experiments.
The meaning of Thousand Years Dream is: Flying Dream.
