China’s Lunar Rover Travels 565.9 Metres on Moon’s Far Side

BEIJING, The lander and the rover of the Chang’e-4 probe, have been switched to the dormant mode, for the lunar night, after working stably for the 23rd lunar day, according to the Lunar Exploration and Space Programme Centre of China National Space Administration.

The lander was switched to dormant mode at 9:40 p.m. Friday (Beijing Time) as scheduled, and the rover, Yutu-2 (Jade Rabbit-2), at 12:00 p.m. Friday, said the centre.

A lunar day is equal to 14 days on Earth, and a lunar night is the same length. The Chang’e-4 probe, which switched to dormant mode during the lunar night, due to lack of solar power, had survived 660 Earth days on the far side of the moon as of yesterday, and the rover has travelled 565.9 metres.

During the 23rd lunar day, Yutu-2 went north-west, travelling towards an area with basalt, and an impact crater area with high reflectivity. En route to the destination, the near-infrared spectrometer on the rover was used to detect a rock about 30 cm in diameter. The research team is analysing the transmitted data.

Scientists carried out the first systematically documented measurements of radiation on the moon with data acquired by the neutron radiation detector on board. According to the study, published in the journal Science Advances, the moon’s surface is highly radioactive, approximately two to three times the International Space Station, five to ten times a civil flight, and 300 times the surface of the earth in Beijing.

The study provided a reference for the estimation of the lunar surface radiation hazards and the design of radiation protection for future lunar astronauts.

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.
