China's first moon lander, Chang'e-3, automatically "awakened" on Thursday after "sleeping" during the lunar night, entering its 28th lunar day, China's State Administration of Science, Technology and Industry for National Defense (SASTIND) announced on Friday.
The spacecraft has withstood the test of extremely low temperatures experienced during 27 lunar nights since its successful soft landing on the moon in December 2013, according to a statement by the SASTIND. The probe has exceeded its operational life of one year and has been in service for 15 extra months since landing on the moon on Dec 14, 2013.
Although the moon lander has already exceeded its design life by 14 months, its astronomical telescope and the other surveying devices it carries are still functioning well. Lunar rover Yutu, which hitched a ride with Chang'e-3, was designed to operate for six months.
"Now, because of a mechanical control abnormality, Yutu is immobile. The defect also affected the solar panels that cover the rover during the lunar night to protect it from the harsh temperatures. Despite the panels not working, Yutu still continues to collect and sent data to Earth thanks to its innovative temperature control system,"
