記者昨天從中國航天科技集團獲悉,目前,嫦娥二號衛星距離地球已超過3500萬公里。預計星地距離將於今年7月14日達到5000萬公里,2014年7月有望達到1億公里。技術人員通過分析認為,嫦娥二號飛行距地最遠可達到約3億公里。

       Chang'e II, China's second moon orbiter launched into space on Octorber 1st, 2010, is now over 35 million kilometers away from Earth. It is estamitated, that till July 14th this year it will be about 50 million kilometers, while till July next year(2014) 100 million kilometers; meanwhie, it can be as far as 300 million kilometers away from Earth according to the analysis by technicians, said reporters from China Aerospace Corporation on 31st May.

嫦娥二號在完成為探月二期月球軟著陸任務開展先期技術驗證和深化科學探測的既定目標之後,又挖掘潛力,利用衛星剩餘能力,相繼實現了月球、拉格朗日點和小行星多類目標、多項任務的探測,成為我國首顆飛入行星際的探測器。

 Chang'e II has now become China's first interplanetary probe, by taking advantage of its surplus fuel and capacity in achieving the multiple detecting tasks and targets, such as the explorations of the Moon, Sun-Earth L2 point and the 4179 asteroid in succession after it sucessfully finished the set targets of testing and verifying the technology for the soft landing on Moon in the second-term Moon-exploration task and deepening the scientific explorations.

在後續的星際飛行中,嫦娥二號飛行目標將主要聚焦在星載設備長壽命考核、自主飛行能力、行星際遠距離測控驗證等方面。

 In future interplanetary flight, the targets of Chang'e II will focus on checking the longevity of the on-board apparatuses and the automatic filght ability and the verification of the remote observation and control ability of interplanetary probe.

Note:

Chang'e 2 (Mandarin: [t??ɑ??.?? ɑ?? xɑ??], simplified Chinese: 嫦娥二号; traditional Chinese: 嫦娥二號; pinyin: Cháng'é èr hào) is a Chinese unmanned lunar probe that was launched on 1 October 2010.[1] It was a follow-up to the Chang'e 1 lunar probe, which was launched in 2007. Chang'e 2 was part of the first phase of the Chinese Lunar Exploration Program, and conducted research from a 100-kilometer-high lunar orbit in preparation for a 2013 soft landing by the Chang'e 3 lander and rover.[2][3] Chang'e 2 was similar in design to Chang'e 1, although it featured some technical improvements, including a more advanced onboard camera with a resolution of one meter. Like its predecessor, the probe was named after Chang'e, an ancient Chinese moon goddess. The total cost of the Chang'e 2 mission was approximately CN?900 million (US$134 million).[4]

After completing its primary objective, the probe left lunar orbit for the Earth–Sun L2 Lagrangian point, to test the Chinese tracking and control network, making the China National Space Administration the third space agency after NASA and ESA to have visited this point.[5] It entered orbit around L2 on 25 August 2011, and began transmitting data from its new position in September 2011.[6][7] In April 2012, Chang'e 2 departed L2 to begin an extended mission to the asteroid 4179 Toutatis,[8][9] which it successfully flew by in December 2012.[10][11] This success made China the fourth spacefaring entity to directly explore asteroids, after the United States, the European Union and Japan. As of 2013, Chang'e 2 is conducting a long-term mission to verify China's deep-space tracking and control systems.[12] “以上採自維基百科”
