Advancing Environmental and Climate Research - Sentinel-1C Delivers First Data

Integrating Earth Observation and life sciences at universities is key to addressing climate change and biodiversity loss.

ESA has officially decommissioned the Sentinel-1B satellite following an unresolved power supply problem that has kept it inactive since December 2021. Launched in 2016 as part of the Copernicus program, Sentinel-1B played a vital role in providing radar data for environmental monitoring, emergency response, and climate studies. Despite extensive efforts, the technical issue could not be resolved, leading to its end of mission in August 2022.   

Meanwhile, Sentinel-1C, launched successfully in December 2024, has begun delivering its first high-quality radar images. Equipped with advanced synthetic aperture radar technology, Sentinel-1C ensures continuity of the program’s critical services, including surface water monitoring, disaster management, and polar ice tracking. 

Easy access to satellite images and scalable computation platforms is important to ecosystem monitoring, innovation in data management, and sustainability research, and plays a key role in equipping future leaders to tackle environmental challenges.
