This undated photo taken by the camera on the Yutu moon rover shows the Chang'e-3 moon lander and the moon surface. The Chang'e-3 lander entered its third dormancy on early Feb. 23, 2014. China's lunar rover Yutu also entered the dormancy on Feb. 22, with the mechanical control issues that might cripple the vehicle still unresolved. According to the State Administration of Science, Technology and Industry for National Defence (SASTIND), Yutu only carried out fixed point observations during its third lunar day, equivalent to about two weeks on Earth. Yutu's radar, panorama camera and infrared imaging equipment are functioning normally, the control issues that have troubled the rover since January persist. (Xinhua/SASTIND)
