2012年12月13日,中国深空探测征程再传佳音—嫦娥-2月球探测器在飞离日地拉格朗日2点(L2)后的195天,成功飞抵距地球约700万千米远的深空,以10.73km/s的相对速度,与图塔蒂斯(Toutatis)小行星由远及近擦身而过,最近相对距离只有3.2km,交会时嫦娥-2上的星载监视相机对小行星进行了光学成像,首次实现中国对小行星的飞越探测。2013年1月5日,嫦娥-2飞抵距地球超过1000万千米的深空。嫦娥-2是中国科技重大专项探月工程二期的先
On December 13, 2012, China’s deep space exploration journey re-transmitted the good news - Chang’e-2 lunar probe flew from the Earth Lagrange 2 points (L2) 195 days after the successful fly to the Earth about 7 million km Far deep sky, with a relative speed of 10.73km / s, and Toutatis (Toutatis) asteroid far and near from the body, the recent relative distance of only 3.2km, the intersection of Chang’e-2 satellite surveillance The camera performed an optical imaging of the asteroid, making it possible for the first time to detect the overwhelming Chinese asteroid. On January 5, 2013, Chang’e-2 flew deep into the Earth with more than 10 million kilometers. Chang’e-2 is China’s major science and technology project lunar exploration first two
