Sentinel-1 is the first of the Copernicus Programme satellite constellations for Earth observation operated by the European Space Agency (ESA). Data collected via the satellites are used e.g. for marine and land monitoring, emergency response to environmental disasters, and economic applications.
== Overview == The mission was originally composed of a constellation of two satellites, Sentinel-1A and Sentinel-1B, which shared the same orbital plane. Sentinel-1B was retired following a power supply issue on 23 December 2021, which left Sentinel-1A the only satellite of the constellation to be operating, until Sentinel-1C was successfully launched on 5 December 2024. Sentinel-1D launched in November 2025.
