The Yutu is a Chinese lunar vehicle created to investigate the surface of the Moon. It is 1.5 meters long, and weighs 120 kilograms. It was part of the Chinese mission Chang E3. In the middle of December 2013, the Yutu rover was already rolling on the lunar surface.
On February 12, 2014, the Chinese government announced that the Yutu rover had been disabled. The reason, a failure that prevented him from sheltering during the lunar night, which lasts 14 Earth days, and in which temperatures can fall below -153 degrees Celsius.
Only one day later, on February 13, the Chinese explorer robot reactivated again, being able to capture and emit signals despite its damage.
The lunar rover Yutu was equipped with several cameras and an articulated arm for excavations. Its mission was to analyze the lunar geology and try to find natural resources.
Thanks to investigations of the lunar rover Yutu, evidence of at least nine layers of rock has been discovered at different depths under its wheels. This indicates that the area of the Moon on which it was located, 50 meters away from a 450-meter crater known as C1, has been highly active for the past 3.3 billion years.
