China's first lunar rover, Yutu, and the lander together formed the Chang 'e-3 probe. The design mass of Yutu lunar rover is 140 kg, and the energy source is solar energy, which can withstand the extreme environment such as vacuum on the moon surface, strong radiation and extreme temperature from-180℃ to-150℃.

The lunar rover is equipped with scientific detection instruments such as panorama camera, infrared imaging spectrometer, lunar radar, particle excited X-ray spectrometer, etc.

2019,65438+The Chinese lunar exploration project Chang 'e-4 lander and Yutu-2 lunar rover successfully landed at the Von Kamen crater in the Antarctic-aitken basin on the back of the moon, setting many firsts and firsts in one fell swoop.

For example, this is the first time in the world to achieve a soft landing and patrol survey on the back of the moon, the first time to land at the high latitude of the moon, and the first time to relay communication between the back of the moon and the earth. 20 19, 12, Yutu-2 also became the lunar rover with the longest working time on the moon.

The Jade Rabbit Lunar Rover sparkles and dazzles people. "Golden Flower" is to reflect the bright light of the moon during the day, reduce the temperature difference between day and night, block the radiation of various high-energy particles in the universe, and support and protect the infrared imaging spectrometer and laser dot matrix device in the belly of the lunar rover.

There are two solar panels that can be opened on the shoulder of the lunar rover Yutu, and there are six wheeled mobile devices below. Jade rabbit has extremely high requirements for wheels. During the development process, after comparing dozens of schemes such as four-wheel, six-wheel, eight-wheel, crawler-type and so on, researchers finally determined the scheme of "six-wheel independent drive and four-wheel independent steering".

"Jade Rabbit" is equipped with an antenna for dialogue and communication between the earth and the moon; Navigation cameras overhead and obstacle avoidance cameras front and rear; Mechanical arm for drilling, grinding and sampling. "Jade Rabbit" has achieved all "Made in China", and the domestic production rate has reached 100%.
