（北京4日综合电）中国的月球探测器“嫦娥四号”周四上午成功登陆月球背面，成为第一个在月背软着陆的人类探测器。当天晚上，“嫦娥四号”上的月球车“玉兔二号”顺利分离，并在月背上留下第一道痕迹。

周四晚10时22分左右，“玉兔二号”月球车驶过月球表面，“嫦娥四号”上的监视相机，拍到玉兔二号在月背留下的第一道痕迹，并通过“鹊桥”中继星将影像图顺利传回地面。

嫦娥四号周四成功着陆月背后，科技人员按计划展开了着陆器与月球车分离的各项准备工作，对“鹊桥”中继星状态、着陆点环境参数、设备状态、太阳入射角度等两器分离的实行条件，进行了最终检查确认。

周四午3时07分，科技人员在北京航太飞行控制中心，通过“鹊桥”中继星向嫦娥四号探测器发送指令，两器分离开始。从北京航太飞行控制中心飞控大厅萤幕上可见，嫦娥四号着陆器矗立月面，太阳翼呈展开状态。月球车立于着陆器顶部，展开太阳翼，伸出桅杆。随后，月球车开始向转移机构缓慢移动。转移机构正常解锁，在着陆器与月面之间搭起一架斜梯，月球车沿着斜梯缓缓走向月面。晚上10时22分，月球车踏上月球表面。
