China's Moon Rover Yutu goes to sleep as Night Approaches

ChinaAfter the first lunar night for the mission fell, China's moon rover 'Yutu' was reported to have gone to sleep at 5:23 a. m. Beijing time on Thursday. The new has been confirmed by the State Administration of Science, Technology and Industry for National Defence.

Beijing Aerospace Control Center gave the command to Yutu to go on sleep mode. It takes 14 days on earth for one night to get over on the moon. During this time, the temperature goes down to minus 180 degree Celsius. As a result, there is no other source available there to provide light to Yutu's solar panel.

According to scientists, a Yutu has been outfitted with a thermal control system to help it survive the night. The system has a radioisotope heat source.

Yutu and the lander are part of the Chang'e-3 mission. The soft and smooth landing was recorded on December 14. After this, Yutu separated from the lander.

A lot of data has been collected by both of them as of now. "The brief Apollo missions were terminated before we could start investigating the requirements for longer term missions away from Earth", said Stephen Mackwell, director of the Lunar and Planetary Institute in Houston.
