A few more details dribble out regarding the problems tht China’s Yutu (Jade Rabbit) rover is having on the Moon:\u00a0China Exclusive: Control circuit malfunction troubles China’s Yutu – Xinhua<\/a><\/p>\n

China’s Yutu (Jade Rabbit) moon rover suffered a control circuit malfunction in its driving unit, which troubled its dormancy in extremely low temperature, a scientist said on Saturday.<\/em><\/p>\n

The control circuit problem prevented Yutu from entering the second dormancy as planned, Ye Peijian, chief scientist of the Chang’e-3 program, told Xinhua in an exclusive interview.<\/em><\/p>\n

“Normal dormancy needs Yutu to fold its mast and solar panels,” said Ye. “The driving unit malfunction prevented Yutu to do those actions.”<\/em><\/p>\n

The rover is currently in another 2 week long night and will experience extremely low temperatures. The rover has radioisotope heater units<\/a>\u00a0(RHUs) to keep its internal systems warm. However, if the rover is not configured properly\u00a0before a night period starts<\/span>, e.g. closing panels to keep heat from escaping and putting solar panels in the right orientation, it may have problems powering back up when daylight returns.<\/span><\/p>\n
