Chinese Moon Rover Says an Early Goodnight

hackingbear writes "The Chinese moon rover, Jade Rabbit, encountered an abnormality in its control mechanism before its planned sleep during the 14-day-long lunar night. In the form of a diary, the Jade Rabbit said, "The shi-fu ('kung-fu masters,' meaning the scientists and engineers) are working around the clock trying to fix the problem and their eyes look like a rabbit's (red due to fatigue), but I may not be able to survive over this lunar night." (translated, original in Chinese.) The rover landed on the moon on Dec 14 and was designed to operate for three months."
