The Chinese probe Chang # 4, which for the first time in history came to the hidden moon face, "woke up" from a "two-week" serenity, lunar night time.
During this period the temperature has decreased 190 degrees below zero, "cooler than scientists expected," China Space Agency (CNSA) reported.
Lunar night forced Chang & 4 on inactivity, because it works with solar energy, which has caused its awakening to be programmed to match the new arrival of sunlight, says the National Space Administration of China (ANEC).
In the case of a vehicle, baptized as Yutu 2, the "Alarm Clock" was broadcast at 8:00 on Tuesday, while the Moon Landing Module concluded its hibernation at 20.39 in China on Wednesday.
In order to resist the low temperatures, both devices, now separated by 18 meters, had a minimum strength batteries. ANEC also stated that all instruments were they continued their activities.
Launched from Sichuan Central China Region on December 8, Chang # 4 was marked Jan. 3 is the turning point of space exploration when it successfully falls to the hidden moon side.
Among the experiments conducted by the probe is capturing low-intensity waves or spinning plants on the Moon in pots that have created the Earth's atmosphere.
Last January 15, ANEC released a photograph of this last experiment in which the appearance of a cotton plant survived several hours before the lunar night came and the consequent fall in temperature.
