由中国航天科技集团公司研制、发射的“嫦娥二号”卫星,进行了中国航天史上迄今航天器飞行最远的一次“太空长征”。与“嫦娥一号”卫星38万km的飞行距离相比,超期服役近两年的“嫦娥二号”卫星于2013年1月5日23点46分飞行距离突破1000万km,这标志着我国深空探测能力获得新的跃升。“嫦娥二号”卫星于2010年发射,在世界上首次实现从月球轨道出发,进入距离地球约150万km的日地拉格朗日L2点,并近距离探测距离地球700万km的图塔第斯小行星,在燃料最优化分析利用、轨道
The “Chang’e II” satellite, developed and launched by China Aerospace Science and Technology Corporation, conducted the “Space Long March” which is the furthest spacecraft flight in the history of China’s spaceflight. Compared with the flight distance of 380,000 km of Chang’e-1 satellite, the Chang’e II satellite which has been in service for over two years exceeded 10 million km at 23:46, January 5, 2013, This marks a new leap forward in our deep space exploration capability. “Chang’e II” satellite was launched in 2010 and is the first in the world to embark on lunar orbit at an angle of L2 to the Earth Day Lagrange approximately 1.5 million km above the Earth and to detect at a distance of 7 million km Tudas asteroids, utilized in fuel optimization analysis, orbit
