The Chinese investigation Chang's 4, which at the beginning of the month first arrived in the history of the hidden face of the moon, woke up from the "siesta" of two weeks, the duration of the lunar night.
At that time the temperature dropped 190 degrees below zero, "colder than scientists," the Chinese Space Agency (CNSA) reported.
The moon night forced Chang to 4 to inactivity, because it works with solar energy, which has caused its awakening to be programmed that coincides with the new advent of sunlight, the National Space Administration of China (ANEC) said.
In the case of the vehicle, baptized as Utah 2, the "alarm clock" sounded on Tuesday at 8:00 am, while the moon landing module completed its hibernation at 20.39 in China on Wednesday.
To withstand low temperatures, both appliances, now separated by 18 meters, had minimum power supplied by the battery. ANEK also pointed out that all instruments they continued with the activity.
Began from the Central China Region of Sichuan on December 8, Chang's 4 marked on January 3 is a milestone for space exploration when it successfully landed on the hidden side of the moon.
Among the experiments carried out by the investigation are the capture of low intensity waves or germination of plants on the moon in containers that recreate the Earth's atmosphere.
Last January 15th, ANEC published a photo of the latest experiment showing the appearance of a cotton factory that survived hours before the advent of lunar night and the consequences of the fall in temperature.
