Arianespace will launch the Sentinel-1D satellite on Ariane 6's third commercial mission from Europe's Spaceport in French Guiana on November 4, 2025. The Sentinel-1D satellite is part of Copernicus, the Earth observation component of the European Union's Space Program.
Sentinel-1D will carry advanced radar technology to provide an all-weather, day-and-night supply of imagery of the Earth's surface, delivering data essential to monitoring sea ice, track icebergs and glaciers, subsidence, and oil spills.
