China's lunar rover Yutu-2 has driven 318.62 meters on the far side of the moon to conduct scientific exploration of the virgin1 territory.
 
中国月兔二号月球车已在月球背面的处女地上行驶318.62米。
 
 
Both the lander and the rover of the Chang'e-4 probe have ended their work for the 11th lunar day, and switched to dormant2 mode for the lunar night on Monday (Beijing time), according to the Lunar Exploration and Space Program Center of the China National Space Administration.
 
The rover is now located 218.11 meters northwest of the lander.
 
China's Chang'e-4 probe, launched on Dec. 8, 2018, made the first-ever soft landing on the Von Karman Crater3 in the South Pole-Aitken Basin on the far side of the moon on Jan. 3.
 
A lunar day equals 14 days on Earth, a lunar night the same length. The Chang'e-4 probe switches to dormant mode during the lunar night due to a lack of solar power.
 
During the 11th lunar day of the probe on the moon, the scientific instruments on the lander and rover worked well, and a new batch4 of scientific detection data was sent to the core research team for analysis.
 
Scientists are planning the future exploration route for the rover.
 
As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation5 cycle, and the same side always faces Earth.
 
The far side of the moon has unique features, and scientists expect Chang'e-4 could bring breakthrough findings.
 
The scientific tasks of the Chang'e-4 mission include conducting low-frequency radio astronomical6 observation, surveying the terrain7 and landforms, detecting the mineral composition and shallow lunar surface structure and measuring neutron8 radiation and neutral atoms.
 
The Chang'e-4 mission embodies9 China's hope to combine wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia.
