Yutu enters hibernation again with its technical problems unresolved

Yutu on surface (Xinhua) China's Yutu lunar rover entered its third two-week hibernation period Saturday with technical problems that earlier appeared to jeopardize the mission unresolved, official media reported. The rover entered hibernation as lunar night began Saturday still suffering from unspecified "mechanical control issues that might cripple the vehicle," according to the Xinhua news agency. Those issues have not affected the rover's instruments, including radar, panoramic camera, and infrared imager, which are all working. However, the problems have apparently prevented the rover from moving, as the report indicated Yutu was limited to "fixed point observations" during the latest lunar day. Officials had reported the technical problems with the rover prior to going into hibernation last month, and problems establishing contact with the rover after that hibernation period ended two weeks ago led to reports that the rover had died. Yutu arrived on the Moon in December with the Chang'e-3 lander; that spacecraft also went into hibernation this weekend after carrying out observations with its instruments.
