BEIJING, July 29 (Xinhua) — The following is a summary of published science and technology news of China.
MARS PROBE CAPTURES IMAGES
China’s Mars probe, Tianwen-1, captured images of the Earth and Moon, about 1.2 million kilometers from Earth, the China National Space Administration said on Tuesday.
China launched its first Mars mission Tianwen-1, which means Questions to Heaven, on July 23, marking the country’s first step in planetary exploration of the solar system.
FOSSIL WOOD DISCOVERED
Researchers have discovered a fossil of a new extinct conifer wood species in east China’s Zhejiang Province, according to the Chinese Academy of Sciences (CAS).
The species, Brachyoxylon zhouii, dating back to the Cretaceous period about 110 million years ago, was found by a team led by researchers with the Nanjing Institute of Geology and Palaeontology under the CAS and the Chinese Academy of Geological Sciences.
IMPERVIOUS SURFACE MAPPING
Chinese researchers have generated a global 30-meter impervious surface map with high accuracy.
The amount of impervious surface is an important indicator in monitoring the intensity of human activities and environmental changes. The use of remote sensing techniques is crucial to undertake global mapping of impervious surfaces covering large areas.
