The Chinese probe Chang & # 39; e 4, which for the first time in the beginning of the month came to the hidden side of the moon, "woke up" from the two-week "siesta" – the moon night.
During this time the temperature dropped to 190 degrees below zero, "Cooler than the scientists expected," reported the Chinese Space Agency (CNSA).

In the case of a vehicle baptized as Yutu 2, an alarm clock sounded at 20:00 on Tuesday, while the moon landing module ended with hibernation Wednesday – 20.39 in China.
To withstand the low temperatures, both devices now separated by 18 meters were a minimum power battery. ANEC also stated that all the tools they resumed their activity.
Opened from China China Sichuan Region on December 8 January 3, space exploration phase successfully landing on the hidden side of the Moon.
The probe experiments include low-intensity waves or plant germination in lunar containers that restored the Earth's atmosphere.
On 15 January last year, ANEC published a photograph of this last experiment showing a cotton plant outbreak that lasted a few hours until the arrival of the Moon night and the resulting temperature drop.
