China's lunar lander has woken up by a freezing fourteen sleep hibernation to find night temperatures on the moon's dark side are colder than previously thought, the National Space Bureau said Thursday.

The temperatures on the moon's surface dropped to minus 190 degrees (-310 degrees Fahrenheit) during the probe's first moon night, which was "colder than scientists expected," said China's National Space Management (CNSA).
The night time temperatures were recorded by the Chinese probe after it became active on Wednesday after a sleep that lasted for about two soils.
They were lower than those occupied by former US missions to the nearest side of the moon, Zhang He, executive director of the Chang 4 e mission, told the Xinhua news agency.
"This is probably due to the difference in soil composition between the two sides of the moon," he said.
A rover released from the probe -Dubbed Yutu-2 (Jade Rabbit) after the Moon-goddess pet – resumed operations "as planned" on January 29 and will conduct experiments in the Von Karman crater, CNSA said in a statement.
Chang & e-4 is equipped with instruments developed by researchers from Sweden, Germany and China.
It has the task of studying the moon environment, cosmic radiation and the interaction between solar wind and the moon's surface.
The probe will now continue with its experiments, CNSA says.
Scientific instruments aboard China's Former Chang-3-moon mission, sent in late 2013, has resisted over 60 moon nights and is still in operation, Xinhua said.
