摘要
嫦娥二号承担着试验直接奔月的新轨道,试验验证月面软着陆相关的关键技术的使命。嫦娥二号绘制了全月球7 m分辨率的影像图和嫦娥三号着陆区虹湾分辨率为1 m的高清图像,圆满完成各项科学探测任务。嫦娥二号在日地拉格朗日L2点监测太阳活动,在距离地球700万km处与4179"战神"号小行星最近距离小于1 km的交会探测,拍摄到分辨率10 m的小行星形状、大小与表面结构的高清图像。当前嫦娥二号已经远离地球6 500万km,成为绕太阳运行的人造小天体。
Chang＇E-2 （CE-2） was intended to test a new direct lunar entry orbit, and to test and verify key technologies related to soft landing on the Moon. CE-2 obtained 7 in resolution image map of the whole lunar surface and high resolution （1 m/pix） images of Sinus lridum, the future landing site of Chang＇E-3. CE-2 monitored solar activity at the Earth-Sun L2 Lagrangian point, and flew by asteroid 4179 Toutatis 7 000 000 km away from Earth. At a minimum rendezvous distance less than 1 km, CE-2 obtained high resolution images （10 rn/pix） of Toutatis showing its shape, size, and surface structures. Currently CE-2 is 65 000 000 km away from the Earth that became a manmade small body orbiting the Sun.
