BEIJING, Sept. 8 (Xinhua) -- The following is a summary of published science and technology news of China.


China launched a new optical remote-sensing satellite from the Taiyuan Satellite Launch Center in northern China's Shanxi Province on Monday.

The Gaofen-11 02 satellite was launched by a Long March-4B rocket. It will be mainly used for land surveys, city planning, land rights confirmation, road network design, crop yield estimation and disaster prevention and mitigation.


China will see intensive satellite launches for the country's space-based Internet-of-Things (IoT) network in 2021, sources with the China Aerospace Science and Industry Corporation (CASIC) said.

The CASIC is scheduled to launch 12 satellites of the Xingyun project, China's first low-Earth-orbit narrowband constellation for IoT operated by its subsidiary Xingyun Satellite Co. The company plans to send a total of 80 satellites into space to complete the three-stage network around 2023.


Chinese researchers have found that the impact of human activities on the Aral Sea is far greater than that of climate change.

The Aral Sea, located between Kazakhstan and Uzbekistan, was once the world's fourth-largest inland waterbody.

Its area saw a sharp contraction since the 1960s due to large-scale reclamation and construction of water conservancy projects, thereby seriously affecting the ecosystem of the waterbody.


Researchers have found that the loss of Arctic sea ice intensified the transport of pollutants, such as aerosols, to the Qinghai-Tibet Plateau.

Due to the influence of atmospheric circulation, aerosols emanating from South and Central Asia around the Qinghai-Tibet Plateau are transported to the plateau and affect its climate and environment. Enditem
