Economic development and people's prosperity. With the reform and opening up and the rapid economic development, the people are getting richer and richer. China's GDP ranks fourth in the world. The educational level of the people has generally improved. 4. Open the door to the world. Intensify reform and opening up, increase foreign exchanges, hold various international exchanges and forums, participate in various international rescue activities and safeguard world peace. 1On April 24th, 970, China's first artificial earth satellite "Dongfanghong-1" was successfully launched by the Long March-1 carrier rocket, and the music of "Dongfanghong" spread all over the world, thus China entered the era of exploring space. 1975165438+1On October 26th, the Long March II D carrier rocket successfully launched a recoverable satellite. After three days in orbit, the satellite was successfully recovered as scheduled, and China became the third country in the world to master the satellite recovery technology. Since 1970s, the remote sensing information obtained by recoverable satellite remote sensing has played an important role in land survey, resource survey, topographic mapping and disaster prediction. 1On April 8th, 984, cz-3 successfully launched Dongfanghong-2 experimental communication satellite, which indicated that China Aerospace mastered the technology of using hydrogen-oxygen engine and twice ignition in weightlessness, and became the fifth country in the world to develop and launch a geostationary orbit satellite. 1985101On October 25th, the government of China announced that the Long March series of launch vehicles would undertake international launch and satellite launch missions. Since then, China Aerospace has entered the international market. Since1launched AsiaSat- 1 on April 7, 1990, China has successfully launched 26 foreign satellites by 2000. 1On September 7th, 988, Fengyun-1 meteorological satellite was successfully launched by cz-4. Fengyun-1 is the first sun-synchronous polar-orbiting meteorological satellite in China, which has played a great role in meteorological observation, marine fishing, agricultural yield estimation, medium and long-term weather forecast and meteorological research. 1August, 1992 14, the Long March II bundled carrier rocket successfully launched the Australian "Ossett BI" communication satellite developed by Hughes Company of the United States. The Chang-2 bundled launch vehicle has made great achievements in large thrust engine, large satellite fairing and rocket bundling technology. China Aerospace has the ability to launch all kinds of large-load commercial satellites. 1997 May 12, the Long March 3A carrier rocket successfully launched Dongfanghong-3 communication satellite, and China achieved a major breakthrough in high-capacity communication satellite technology. 1On August 20th, 997, long march 3b successfully launched the Philippine Mabuhai communication satellite. Long March 3 B uses a large thrust hydrogen-oxygen engine, which makes its synchronous transfer orbit carrying capacity reach 5 tons, and enhances China's competitiveness in the international commercial satellite launch market. 19991June14th, the Long March 4B carrier rocket successfully launched the Resource-1 satellite, which was jointly developed by China and Brazil. Its comprehensive performance has reached the international advanced level and set a good example for China's successful cooperation in the field of aerospace high technology. 1October 20th 1999, 165438+ The new Long March launch vehicle successfully launched the Shenzhou test ship,1October 20th, the spacecraft was successfully recovered 165438+2 1. China's historic breakthrough in manned space technology is a milestone in China's space history. On June1+1October 10, China successfully launched the Shenzhou II experimental spacecraft. After completing the space science and technology test mission in space as scheduled, he returned to the central area of Inner Mongolia on June+10/October 16, 65438. On March 25th, 2002, China successfully launched the Shenzhou III experimental spacecraft, circled the earth 108, and landed in central Inner Mongolia on 1 day. On February 30th, 2002, at 65438, China successfully launched the Shenzhou IV spacecraft. From June 65438+1October 15 to June 16, 2003, China successfully conducted its first manned space flight. Chinese astronaut Yang Liwei flew 14 laps in Shenzhou 5 manned spacecraft, which lasted 2 1 hour for 23 minutes. After successfully completing all scheduled operations, he returned to the main landing site safely. From June 65438+1October 12 to June 16, 2005, China successfully conducted its second manned space flight. China astronauts Fei and Nie Haisheng took the Shenzhou VI manned spacecraft to run 76 times in space, which lasted 4 days 19 hours and 33 minutes, realizing multi-person multi-day flight and safely returning to the main landing site.

On 20071October 24th 18: 05, Chang 'e-1 probe was successfully launched from xichang satellite launch center by the Long March 3A rocket. It is the first lunar probe independently developed and launched by China. At 23: 35 on April 25th, 2008, China's first data relay satellite "Tianlian No.1 0 1" was successfully launched by the Long March III C carrier rocket in xichang satellite launch center. On September 25th, 2008, Shenzhou VII was launched on 2 1: 10, and returned to the main landing site safely on September 28th. China's space industry started in the 1950s and 1960s. 1965, China's first artificial satellite plan was put into practice. Although it experienced more hardships than usual in a special period, after more than five years of hard work, it was finally developed successfully, and the stars and arrows were in full swing, ready to go. 1On April 24th, 970, the Long March-1 carrier rocket was launched for the first time, successfully putting China's first man-made earth satellite Dongfanghong-1 into the scheduled orbit, which opened the prelude to China's space activities. At present, China has initially formed four major satellite series-recoverable remote sensing satellite series, "Dongfanghong" communication and broadcasting satellite series, "Fengyun" meteorological satellite series, "practical" scientific exploration and technical test satellite series and "resources" earth resources satellite. China is the third country in the world to master satellite recycling technology, and the success rate of satellite recycling has reached the international advanced level; China is the fifth country in the world to independently develop and launch a geostationary orbit communication satellite. The main technical indexes of China Meteorological Satellite and Earth Resources Satellite have reached the international level in the early 1990s. In recent years, six communication, earth resources and meteorological satellites developed and launched by China have been put into use, with stable work and good performance, resulting in good social and economic benefits. Different from the previous launch time of Shenzhou series, Shenzhou 5 chose daytime. In the past, the launch time of shenzhou spaceship was usually in the early morning and midnight. According to experts, space launch needs to determine a certain time of day as the opportunity for spacecraft launch, which is the so-called "launch window". It turns out that the launch window of Shenzhou series is chosen at night, mainly to facilitate the optical tracking and measuring instruments on the ground to capture the target when the spacecraft is launched. Shenzhou 5 chose to launch in the daytime, mainly considering that the daytime temperature will be beneficial to the work of astronauts, and it is easy to fully protect the personal safety of astronauts in case of accidents. 3. Shenzhou VI: Yang Liwei was the only passenger of Shenzhou VI, and in June 5438+1October 65438+February, two guests were welcomed in space-two astronauts Fei and Nie Haisheng of China Shenzhou VI. The increase in the number of people has brought different changes to all aspects of tasks and engineering systems. For example, the equipment to be carried has to be doubled, and there are also two astronauts' cooperation problems. Double flight can evaluate the performance of flying ships and other engineering systems more comprehensively than single flight. 4. Shenzhou VII: The Shenzhou VII flight will also be tested in a space relay station. The completion of this task will lay a good foundation for the establishment of TT&C network in China, greatly improve the coverage and efficiency of TT&C network, and lay a better foundation for manned spaceflight to engage in activities that require higher TT&C coverage in the future. 1999165438+1At 6: 30: 07 on October 20th, China's first experimental spacecraft, Shenzhou I, was successfully launched, and China became the third country in the world with manned space technology after the United States and Russia. After 2 1 hour space science experiment, it landed successfully at 3: 4/day on 2 1. The successful launch and recovery of the Shenzhou experimental spacecraft has become another milestone in China's space history. The success date is1999165438+10.21,which is only one month and nine days away from the end of the year. For seven years, many astronauts who count down their calendars every day just want to have a good sleep. But such a simple wish is also an unattainable luxury for many people. In the new drums, "Shenzhou II" set off again. Chinese astronauts driving cranes into space must race against time for the ideal of a nation!
