China's Chang'e-4 probe has survived 500 Earth days on the far side of the moon while conducting a scientific exploration of the virgin territory.

The lander and rover of the Chang'e-4 probe have resumed work for the 18th lunar day on the far side of the moon after "sleeping" during the extremely cold night.

The lander woke up at 3:25 a.m. Sunday (Beijing time), and the rover awoke at 11:53 a.m. Saturday. Both are in normal working order, according to the Lunar Exploration and Space Program Center of the China National Space Administration (CNSA).

The rover Yutu-2, or Jade Rabbit-2, has driven 447.68 meters, and is now 292 meters away from the lander. It has conducted scientific detection on lunar rocks, the lunar soil on its track and some impact craters.

Scientists used the Lunar Penetrating Radar on Yutu-2 to study the geological structure with a depth of 40 meters, unveiling the secrets buried under the surface of the far side of the moon, enriching our understanding about the history of celestial collisions and volcanic activities and shedding new light on the geological evolution on the moon.

Scientists also analyzed the data of the infrared imaging spectrometer on Yutu-2 and revealed the material composition on the moon's far side, verifying that the lunar mantle is rich in olivine, which deepens our understanding of the formation and evolution of the moon.
