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 Program Centre of the China National Space Administration.

The lander was switched to dormant mode at 9.40pm as scheduled and the rover, Yutu-2 (Jade Rabbit-2), at noon on 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 the lack of solar power, had been on the far side of the moon for 660 Earth days as of Saturday, and the rover has traveled 565.9m.

During the 23rd lunar day, Yutu-2 went northwest, travelling toward an area with basalt and an impact crater area with high reflectivity.

Scientists carried out the first systematically documented measurements of radiation on the moon with data acquired by the neutron radiation detector onboard.

According to the study published in the journal Science Advances, the moon’s surface is highly radioactive, approximately two to three times compared to the International Space Station, five to ten times a civil flight, and 300 times the surface of the Earth in BeijingThe 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.

The rover Yutu-2 has far exceeded its three-month design lifespan, becoming the longest-working lunar rover on the moon. — Xinhua
