ESA Launches Third Sentinel‑3 Satellite to Sustain Climate Monitoring

The European Space Agency has launched the third satellite in its Copernicus Sentinel‑3 series, a mission that has become one of the most versatile tools for measuring Earth’s climate systems. Sentinel‑3 collects a wide range of environmental data, from sea‑surface temperature to land‑surface reflectance, and has supplied scientists with critical observations that have shaped our understanding of climate change over the past decade. The new satellite will continue this legacy, ensuring that the continuous stream of high‑quality data remains available for researchers, climate modelers, and policy makers who depend on it to track trends and assess impacts.
