BEIJING, Oct. 27 (Xinhua) -- The following are the highlights of China's key technology news from the past week:
CHINA'S PRIVATE REUSABLE ROCKET
A Chinese reusable carrier rocket that uses liquid oxygen-methane propellants will be launched for the first time in 2021.
The rocket, named the Hyperbola-2, may make up for China's lack of reusable liquid-propellant rockets.
5G UNMANNED MINING TRUCK
China has developed a 5G intelligent unmanned mining truck, according to Science and Technology Daily on Wednesday.
The unmanned mining truck is used for opencast mining. It measures 10.2 meters long, 5.4 meters wide and five meters tall, and has a carrying capacity of 110 tonnes.
In the wilderness of Daocheng, southwest China's Sichuan Province, 4,400 meters above sea level, Chinese scientists are constructing a cosmic ray observation station on an area equivalent to 200 soccer fields.
Huge rocks left from the Ice Age have been blasted. Different detectors are being installed to form a huge "net" to catch the particles generated by cosmic rays in the atmosphere, to help scientists study both the micro and the macro worlds in the universe.
CHINESE MARINE RESEARCH VESSEL
Chinese marine research vessel Haiyang 6 (Ocean 6) has completed its deep-sea exploration mission in the Western Pacific ocean after 122 days and 35,000 km at sea.
