Sentinel-1D with Ariane 6 fairing half-shells

The Copernicus Sentinel-1D satellite photographed next to the Ariane 6 rocket fairing half-shells in preparation for liftoff from the European Spaceport in Kourou, French Guiana, on 4 November 2025.

Together with its sibling Sentinel-1C, Sentinel-1D will significantly enhance the capabilities of the Copernicus Earth observation programme.

The mission will continue to deliver radar images of Earth’s surface, performing in all weathers, day-and-night, providing a service vital for users who depend on frequent updates of critical data, such as disaster response teams, environmental agencies, maritime authorities and climate scientists.
