Saturday night, Chinas space agency got some very bad news, and its only getting worse. The countrys first lunar rover, the Jade Rabbit, ran into a mechanical control abnormality over the weekend, and a growing chorus of experts indicate this may be the end of the line for the robot. Observers say the equipment failure may have disabled the electrical motors needed to close the rovers solar panels, which would have disastrous effects as the rover heads into the two-week lunar night. By the time the lunar night lifts, the rover would be completely inoperable.
