Beijing, April 29 (Xinhua) – Lander and rover probes Chang e-4 resumed work for the fifth lunar day on the opposite side of the month after "sleeping" during an extreme cold night.
Lander woke up on Monday at 7:40 am and the rover, Yutu-2 (Jade Rabbit-2), woke up at 1:45 am. Sunday. Both are in normal working order, according to the Lunar Exploration and Space Program Center of the Chinese National Space Administration.
Rover traveled the accumulated 178.9 meters on the moon and worked one month longer than his designed life.
Launched on December 8, 2018, China's Chang & e-4 spacecraft made its first soft landing on Von Karman Crater in the South Pole-Aitken Basin on the far side of the Moon on January 3rd.
The lunar day is equal to 14 days on Earth and the lunar night is the same length. The Chang-e-4 spacecraft went into sleep mode during the lunar night due to lack of solar energy.
As a result of the tidal locking effect, the revolutionary cycle of the moon 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 deliver breakthroughs.
The scientific tasks of the Chang e-4 mission include low-frequency radio astronomical observation, terrain and relief exploration, mineral composition detection and shallow moon surface structures, and neutron radiation and neutral atom measurements.
Chang & e-4 embodies China's hope of combining human wisdom in a space exploration with four useful costs developed by the Netherlands, Germany, Sweden, and Saudi Arabia.
