BEIJING, Sept. 13 (Xinhua) -- The following are the highlights of China's major technology news from the past week:

CHANG'E-3

After more than 2,400 days on the near side of the moon, China's Chang'e-3 lunar mission continues to help scientists unravel the unknown about Earth's companion in space.

The Chang'e-3 lunar mission has been on the moon for 2,453 Earth days as of Sept. 1, and some of the scientific payloads carried by the lander are still operating. Chinese researchers recently reported finding multilayered young lava flows in the northeast of Mare Imbrium, also called Sea of Rains, where the Chang'e-3 mission made a soft landing in December 2013.

CHANG'E-4 PROBE

Based on data from China's Chang'e-4 probe, Chinese scientists have determined the thickness of the regolith and revealed the fine subsurface structures and evolutionary history of the probe's landing site on the moon's far side.

The study revealed that the landing area of the probe, located within the largest and oldest impact basin on the moon, had experienced multiple impact events and basalt magma eruptions.

REMOTE-SENSING SATELLITE

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.

IOT SATELLITES

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.

ROBOTIC BLOOD SAMPLING

A robotic blood sampling machine was introduced at the 2020 China International Fair for Trade in Services.

With the assistance of AI technologies, the machine can automatically complete the whole process of taking blood samples, including disinfecting and applying a band-aid to the venipuncture site. Enditem
