Yutu still working after expected service span ended

China's moon rover Yutu, which landed on the moon on Dec 14, has exceeded its expected three-month life, and is still working, Chengdu Commercial Daily reported Wednesday, citing Yu Dengyun, deputy chief designer of China's moon exploration project.

Yutu can still receive signals, process information and send data and photos back to earth, but it can't walk due to a mechanical control abnormality, Yu said.

Yutu entered its fourth lunar night on March 24. It is now less than 20 meters away from its lander, and the two can take pictures of and communicate with each other. Yu said the moon exploration project will continue to use the moon rover until it completely stops working.
