Sentinel-2
The Copernicus optical imaging mission for repeated observations of Earth's land and coastal areas.
Why it matters
Open Earth-observation data support environmental monitoring at broad geographic scales.

Overview
Sentinel-2 is a mission with multiple spacecraft, not one permanent view from a fixed point. Its multispectral observations support mapping and change detection. Clouds can obscure optical views.
Educational reference, reviewed . This page is not a live mission-status report.
How it works
An imaging instrument measures reflected light in different spectral bands. Repeated orbital coverage allows scientists to compare surface conditions over time.
