The lander and rover of the Chang'e-4 probe have resumed work for the 14th lunar day on the far side of the moon after "sleeping" during the extremely cold night.
Both the lander and the rover are in normal working order, according to the Lunar Exploration and Space Program Center of the China National Space Administration.
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.
The rover Yutu-2, or Jade Rabbit-2, has worked much longer than its three-month design life, becoming the longest-working lunar rover on the moon.
A lunar day equals 14 days on Earth, and a lunar night is the same length. The Chang'e-4 probe switched to dormant mode during the lunar night due to the lack of solar power.
The scientific tasks of the Chang'e-4 mission include conducting 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 wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia.
China plans to launch the Chang'e-5 probe in 2020 to bring lunar samples back to Earth.
The Chang'e-5 probe includes a lander, an orbiter, an ascender and a returner. The key tasks of the mission will be lunar sample collection, takeoff from the moon, rendezvous and docking on lunar obit and high-speed reentry into Earth' atmosphere.
