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

The lander woke up at 6 pm Tuesday, and the rover, Yutu-2 (Jade Rabbit-2), awoke at 2:16 am Tuesday, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

For the sixth lunar day, the lander's neutron radiation detector and low-frequency radio detector will be restarted to conduct scientific tasks including particle radiation observation and low-frequency radio astronomical observation.

The rover's panoramic camera, detection radar, infrared imaging spectrometer and neutral atom detector will be restarted during the sixth lunar day.

China's 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.

A lunar day equals 14 days on Earth, and a lunar night is the same length. The Chang'e 4 probe switched to a dormant mode during the lunar night due to the lack of solar power.

As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation cycle, and the same side always faces Earth.

The far side of the moon has unique features, and scientists expect Chang'e 4 to provide breakthrough findings.

The scientific tasks of the Chang'e 4 mission include low-frequency radio astronomical observation, surveying the terrain and landforms, detecting the mineral composition and shallow lunar surface structure and measuring neutron radiation and neutral atoms.

The Chang'e 4 mission embodies China's hope to combine human wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia.
