BEIJING -- The lander and rover of the Chang'e-4 probe have resumed work for the 22nd lunar day on the far side of the moon.
The lander woke up at 5:15 am on Saturday (Beijing time), and the rover Yutu-2, or Jade Rabbit-2, woke up at 11:54 am on Friday, sources with the Lunar Exploration and Space Program Center of the China National Space Administration said.
The Chang'e-4 probe, launched on Dec 8, 2018, made the first-ever soft landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan 3, 2019.
A lunar day is equal to 14 days on Earth, and a lunar night is the same length. The Chang'e-4 probe, switching to dormant mode during the lunar night due to the lack of solar power, has survived about 618 Earth days on the moon.
