China has restored communications with its space program's troubled "Jade Rabbit" moon rover, but engineers are still working to fix its mechanical problems, AP quoted state media as reporting Thursday. The official Xinhua News Agency cited Pei Zhaoyu, the lunar probe program's spokesman, as saying the rover had survived the frigid cold of the lunar night that started Jan. 25. The "Jade Rabbit" rover was designed to roam the lunar surface for three months while surveying for natural resources and sending back data. But it ran into problems as it was shutting down in preparation for the lunar night, which lasts two weeks.
