China's lunar rover has driven 170.92 meters on the far side of the moon.
 
中国的月球车已在月球背面行驶170.92米。
 
The rover Yutu-2, or Jade1 Rabbit-2, took a "noon break" from April 2 to April 8, as the temperatures on the moon were extremely high, and continued its exploration, according to the Lunar Exploration and Space Program Center of the China National Space Administration.
 
The rover was sent to the Von Karman Crater2 in the South Pole-Aitken Basin on the far side of the moon on Jan. 3 for the Chang'e-4 mission. It has worked longer than its three-month design life.
 
As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation3 cycle, and the same side always faces the Earth.
 
The far side of the moon was regarded as a virgin4 territory with unique features, and scientists expect important discoveries.
 
The 135-kg Jade Rabbit-2 is the first ever rover to drive on the moon's far side, as well as the lightest rover ever sent to the moon.
 
The rover has scientifically examined some stones on the far side of the moon, which might help scientists find out whether they are from outer space or native to the moon.
 
Scientists hope Jade Rabbit-2 will travel farther to send more images of the unknown terrain5, "listen" to the stories recorded in the ancient lunar rocks, and find more traces of the early history of the moon and the solar system.
