China’s Jade Rabbit moon rover (月球车) has “woken up” since it entered the lunar night two weeks ago.The moon rover,known as Yutu in Mandarin Chinese,and the Chang’e3 lander were restarted by the Beijing Aerospace Control Center (BACC),China’s Xinhua news agency said.
It had been set to sleep for two weeks to ride out extreme climatic conditions and will finally undertake its scientific mission.The Jade Rabbit was “put to sleep” on 26 December at the onset of the first lunar night of the mission.One night on the moon lasts for around two weeks on Earth and during this time,temperatures fall to 180℃—conditions too cold for the equipment to function in.There is also no sunlight to power the Jade Rabbit’s solar panels.
Zhou Jianliang,chief engineer with the BACC,explained:“During the lunar night,the lander and the rover were in a poweroff condition and the communication with Earth was cut off.
“When the night ends,they will be started up with the power provided by sunlight and resume operation and communication according to preset programmes.He added that the Jade Rabbit surviving the lunar night showed Chinese technology had proved successful.
