Ariane 6 fairing release revealing Sentinel-1D

Artist's view of Copernicus Sentinel-1D on its Ariane 6 launcher moments after fairing release.

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

The Sentinel-1 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.
