Chang-e 2, six key technology breakthrough in rendering the West China space race
data for: assembly of the Chang-e II lunar satellite

China, “Chang-e II” lunar exploration began yesterday, the fuel filling. A day earlier, China’s lunar exploration project spokesman said it has completed the testing and inspection of the launch site area, will be at 18:59:57 on on October 1 at the Xichang Satellite Launch Center in lunar satellite. Although from time to time encounter the West “space race” voice of the harassment, but China’s determination never wavered in space exploration, lunar exploration from the first two years alone, the Chinese began a new attempt. Some Western media have commented that this indicates that China’s “space ambitions” and a step forward.
According to reports, this launch will use Long March III carrier rocket, the “Chang-e II” satellite into the perigee altitude of 200 km and an apogee altitude of about 38 million kilometers directly flying to the moon orbit. Satellite moon flight takes about 112 hours, during which the plan 2-3 times orbit correction. As a result of weather and other reasons can not be launched in the first window of time will be October 2 and 3, choose the launch.
for China’s second moon, the United Kingdom, “Belfast Telegraph” September 30, commented that this indicates that China’s space ambitions a step further. China also plans to launch next year, “Space Station” prototype — “One Temple” in preparation for eventually build its own space station. Agence France-Presse said that China has launched the second teeth to complete the final preparations for lunar exploration satellite, everything is ready, the 61 anniversary of National Day was launched. The satellite will conduct a series of tests for launch in 2013, “Chang-e III” to prepare in order to achieve the first unmanned landing on the moon. China in October 2007 launched the “Chang-e One”, lunar flight, and returned high-resolution photographs of the lunar surface. China hopes to collect in 2017 and brought back moon rock samples, and in 2020 to achieve a manned lunar landing. The report also said the country “Luna,” named Chang-e program is aimed at China and Russia on an equal footing with the United States space exploration.
Pang Hao of China’s space experts to the “Global Times” reporter, said, “Chang-e II” is equivalent to pioneer for the future, “Chang E III”, “IV” to prepare for the moon. Lunar exploration purposes experimental techniques, pre-selected landing zone for the photo; scientific purposes, including imaging of the moon, probe construction and so on. The moon to the six key technology breakthroughs, such as the first rocket to the moon probing satellite into earth-moon transfer orbit, the direct flying to the moon, this can save the Earth to the moon flight time, fuel savings of satellites, manned for the future space is important; verify 100 km lunar orbit capture technology, which is equivalent to the satellite to the moon too fast, you need to brake, and the lunar gravity field is uneven, the satellite to the moon to improve the braking capacity. Pang Zhihao said, the future, “Chang E III”, “IV” will encounter a series of complex technical landing, the landing to make the future more secure, the moon will gain experience.
CNN reports the United States reviewed the results of China’s space exploration, said China made great progress in recent years. In 2003, China after the United States and Russia, has become the third person into space in the country, known as China’s space hero Yang Liwei, the first man. 5 years later, Zhai Zhigang became the first Chinese person in space move. “Chang-e II” lunar landing satellite will test key technologies to carry high-resolution stereo camera, the “Chang-e III” landing zone to provide high-resolution photos. “Chang-e II” responsible for ground application system, Chinese media revealed that the moon will get fine exceeding 10 meters on the lunar surface map, which will become by far the most clear full month chart.
the Chinese people are busy for space exploration on the occasion, some Western media and the old tune, rendered from the space race. “Wall Street Journal” website article reported that China plans on October 1 National Day launch second lunar probe the day, it seems to China in Asia space race in the fierce leader. If the “Chang-e II” was successfully launched in China in the manned moon race in another country one step ahead of India. The article also said that China has vowed to complete before the moon landing in 2025, India 2020 years ago, said, “India’s space race between the Soviet Union during the Cold War space-like struggle of the 21st century Asia.” The Associated Press reported said, stretched in the United States and other countries, shortage of funds, the Chinese space program in the context of limited international cooperation is creating a new milestone.
Western media always like to compare India to take, and occasionally provoke a few. In the Indian media yesterday on the “Chang-e II” lunar exploration reports, the reporter did not find such a blatant “Cold War” type of discourse. “Hindu” had in a report, not without pride that China’s lunar mission is seen as a competition with India, the Indian lunar device “lunar spacecraft No. 1,” the release of a lunar probe successfully hit the moon surface, leaving the imprint of the Indian national flag has become the fourth day after United States and Russia to do this country, which has been leading China. The report also said some Chinese analysts have denied that the international community that China is working on an arms race in outer space, saying, stressing that China’s scientific exploration is the purpose of mankind as a whole.
