BEIJING, Oct. 25 (Xinhua) -- The following are the highlights of China's major technology news from the past week:

CHINA'S LUNAR ROVER

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 Center of the 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 noon Friday, said the center.

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 565.9 meters.
