China's bullet-shape satellite test paves the way for very low orbit surveillance network
Chutian-001, which was launched from the Jiuquan Satellite Launch Centre a year ago, showed core capabilities – including satellite system performance, high-resolution smart imaging and space environment monitoring – Hubei Daily reported.
The outlet said the tests showed major progress in key areas, such as precise satellite control in very low orbits, real-time target detection using domestically developed technologies and multi-sensor monitoring of the near-Earth environment.

The report did not disclose the satellite's altitude or specifications such as mass or size. However, images from last year's Zhuhai air show revealed the satellite's streamlined, bullet-shaped body designed to reduce atmospheric drag, a key challenge for spacecraft operating below 300km (186 miles) where air resistance is much greater.
VLEO satellites typically circle the Earth at altitudes between 150km and 300km, offering advantages such as lower signal latency, stronger transmission, reduced power needs and potentially lower launch costs.
However, they must regularly fire on-board thrusters to counter atmospheric drag, which shortens their lifespan and demands more frequent replacement.
As part of China's broader effort to grow its commercial space sector, the Chutian constellation project was launched in July 2023 by China Aerospace Science and Industry Corp (CASIC) in partnership with the Hubei provincial government. The constellation will be deployed in three phases.

Chinese military researchers seek to draw electronic warfare lessons from Ukraine jamming
When Russia invaded Ukraine in February 2022 satellite navigation signals were one of its first targets. The jamming started with civilian navigation systems, but within less than two weeks, military bands had been targeted as well. All satellite navigation systems in the war zone, including the US GPS system, the European Union's Galileo, China's Beidou and even Russia's own Glonass, fell victim. Western powers, led by the United States, immediately launched a counter-jamming mission to stall Russia's attempts, according to a paper by Chinese scientists. While this did not receive a great amount of coverage at the time, some analysts have described it as the first major bout of electronic warfare between major military powers. It also presented a golden opportunity for Chinese observers, particularly given that Beidou was among the systems affected.

Cancer scientist Feng Gensheng leaves US for China as Trump cuts funding
Distinguished cancer expert Feng Gensheng has returned to China this month after 40 years in North America, mostly in the United States. Advertisement Feng, who was promoted to distinguished professor at the University of California, San Diego (UCSD) earlier this year, has joined the Shenzhen Bay Laboratory (SZBL) , where he will serve as director of the Cancer Research Institute. SZBL is a research platform established by Guangdong province and the southern city of Shenzhen to build leading science and technology innovation centres. Feng's research focuses on the mechanisms of liver cancer recurrence and immunotherapy for liver cancer. His most important contribution to the field is the discovery of SHP2, a new kind of enzyme. This type of enzyme can affect the stability of proteins and regulate the activity of other enzymes, which helps us understand the regeneration and differentiation mechanisms of various cells. Advertisement Feng, a fellow of the American Association for the Advancement of Science (AAAS), confirmed he had returned to China.

Hong Kong to look at mosquito-eat-mosquito strategy to tackle chikungunya fever
Hong Kong authorities will explore the use of a mosquito-eat-mosquito strategy deployed by the mainland Chinese city at the epicentre of a recent outbreak of chikungunya fever to control the disease's spread, with one more imported case recorded on Tuesday. Secretary for Environment and Ecology Tse Chin-wan told lawmakers at a special meeting on Tuesday that the government planned to test biological control strategies to curb the spread of the chikungunya virus in Hong Kong, which had recorded six imported cases since August 2. But he acknowledged that the government would have difficulty deploying these tech-driven methods immediately because they required time to develop. The latest case was recorded on Tuesday, involving a 31-year-old man who had stayed in Foshan, the Guangdong province city hit by an outbreak, between August 1 and 3. He returned to Hong Kong and developed a fever, rashes and joint pain on August 8. The next day, he visited Shenzhen and sought medical help there on August 10 but was not hospitalised.
