From Imaging to Intelligence: How Smart Remote-Sensing Satellites Are Changing the Market
Several smart remote-sensing satellites have recently been launched in China and other countries, entering a rapidly expanding applications market and attracting growing industry attention. But what does it mean for a remote-sensing satellite to become “smart”? What benefits could onboard intelligence provide, and how might it help satellite operators reach new markets and deliver services…

Can SAR Map Floods Without Manual Labels or Threshold Tuning?
In brief: Conventional SAR-based flood mapping often runs into two obstacles: thresholds must be adjusted repeatedly by hand, while supervised learning requires large volumes of labeled data. This paper proposes Felz-CNN, also known as the adaptive unsupervised Felz-CNN segment system (AUFCS). The method first uses Felzenszwalb superpixels to divide a SAR image into many internally…

What Really Caused Pakistan’s 2022 Floods: Extreme Rainfall, Snowmelt, or Glacial Lake Outburst Floods?
In brief: Published in Remote Sensing of Environment, this study does more than use Sentinel-1 data to map Pakistan’s catastrophic 2022 floods. It seeks to answer three broader questions: How much of the country was flooded? Why was the disaster so severe? And was it worse than the major flood of 2010? The authors developed…

From Detecting Change to Assessing Risk: Satellite Remote Sensing for High-Mountain Hazards
On August 26, 2026, a cascading debris-flow disaster originating on the Nepal side of the China–Nepal border struck Gyirong Port in Xizang, China. Based on pre- and post-event high-resolution satellite imagery, seismic reports, and imagery transmitted from the affected area, an expert working group organized by China’s Ministry of Natural Resources preliminarily assessed that the…

Mianyang, Sichuan Uses SAR Satellites to Monitor Ground Deformation and Identify Urban Building Safety Risks
Satellite remote sensing is moving beyond specialized surveying and scientific research into practical applications such as urban governance, agriculture, resource management and infrastructure monitoring. This shift is particularly visible in China. In 2025, China launched more than 120 remote-sensing satellites, while its civilian remote-sensing satellite fleet in orbit exceeded 640, maintaining the country’s position as…

From Carbon Emissions to Carbon Sinks: How Satellites Support Carbon Monitoring
As the world continues to pursue net-zero targets, carbon data is becoming an increasingly important foundation for climate governance, corporate emissions reduction, and ecosystem management. Countries need to quantify and assess greenhouse gas emissions more accurately. Companies need an ongoing understanding of emissions changes across their operations and associated facilities. Carbon markets and carbon projects…

From Crop Health to Irrigation Management: How Satellite Remote Sensing Can Help Agriculture Respond to Growing Water Pressure
In the summer of 2026, drought across Europe and the developing El Niño once again drew attention to risks affecting agricultural production and food security. On August 13, the Associated Press reported that persistent heat and drought were affecting agricultural production across Europe, putting crops ranging from potatoes in the Netherlands and maize in Bosnia…
