What is the abbreviation of China's space achievements?
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 space exploration.
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.
198510/kloc-0 On October 25th, the government of China announced that the Long March series of launch vehicles would undertake international launch and satellite launch business, and China Aerospace would enter the international market. From April 7th, 1990, when/KLOC-0 launched the Asia-1 communication satellite, by 2000, China had successfully launched 26 foreign satellites.
On September 7th, 1988, cz-4 successfully launched Fengyun-1 meteorological satellite. 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 long two-bundle 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 jointly developed by China and Brazil, and its comprehensive performance reached the international advanced level, which also set a good example for China's successful cooperation in the field of aerospace high technology.
1999165438+1On October 20th, the new Long March launch vehicle successfully launched the Shenzhou test spacecraft, and the spacecraft was successfully recovered on October 20th 165438+265438. China's historic breakthrough in manned space technology is a milestone in China's space history.
In June 1, 65438+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, circling 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 10 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 carrier 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.
Shenzhou VII was launched at 2 1 on September 25th, 2008, and returned to the main landing site safely on September 28th.
Shenzhou XIII
The successful launch of Shenzhou XIII manned spacecraft opened the longest manned flight in China so far. Three astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu embarked on a six-month space trip, and the China Space Station also welcomed the second batch of astronauts and the first female astronaut.
The space station flies in a near-earth elliptical orbit about 400 kilometers from the Earth. Astronauts live in microgravity, high vacuum, alternating temperature and space radiation. The space station orbits the earth once every 90 minutes, which means that the space station has to feel hot and cold alternately frequently, with the highest temperature reaching 200 degrees Celsius and the lowest temperature reaching-120 degrees Celsius.
Such a magical and harsh space journey has lasted for three months. Astronaut Shenzhou XIII spent half the time in this "business trip in space", not only successfully completed various scientific and technical experiments, but also became more and more accustomed to the living environment of the space station and the busy and wonderful space life.
