BEIJING, Aug. 2 (Xinhua) -- The following is a summary of published science and technology news of China.
AS700 MANNED AIRSHIP
The AS700 airship took off from Zhanghe Airport in Jingmen, central China's Hubei Province, to show its performance and capabilities in serving low-altitude tourism, according to the Aviation Industry Corporation of China (AVIC).
This demonstration flight lasted nearly two hours, simulating low-altitude tourism application scenarios via a planned route.
The airship flew over local parks, an island in the river and other popular scenic spots across the city and then safely returned. It flew at a cruising speed of 60 kilometers per hour and an altitude of 500 meters during the flight, said the AVIC.
HIGH-ORBIT INTERNET SATELLITE
China sent a new high-orbit internet-services satellite into space on Thursday from the Xichang Satellite Launch Center in southwest China's Sichuan Province.
The satellite was launched at 9:14 p.m. (Beijing Time) aboard a Long March-3B carrier rocket and entered its preset orbit successfully.
REMOTE SENSING EXPERIMENTS
Chinese research teams have carried out multi-scale remote sensing joint experiments in north China's Luanhe River basin to achieve three-dimensional quantitative inversion of key ecological parameters such as soil and vegetation, according to the National Space Science Center (NSSC) under the Chinese Academy of Sciences.
Lei Yang, head of the joint experiments and a researcher at the NSSC, explained that soil and vegetation are essential components of terrestrial ecosystems, and that the physical and chemical properties of soil vary significantly with depths while the three-dimensional structure of vegetation is particularly intricate. ■
