China says it has restored communications with its space program's troubled "Jade Rabbit" moon rover, but that engineers are still working to fix its mechanical problems.

The official Xinhua News Agency cited Pei Zhaoyu, the lunar probe program's spokesman, as saying Thursday that the rover has 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.

The problems were a rare setback for China's burgeoning space program, which in recent years has conducted space walks and placed a space station in orbit.
