Sentinel-1D Set to Ensure Continuity of Europe’s Radar Observations of the Oceans

Set for launch on 4 November 2025 from the European Spaceport in Kourou, French Guiana, Sentinel-1D will secure the uninterrupted flow of radar observations provided by Copernicus, the Earth Observation component of the EU Space Programme. It will also strengthen the Copernicus Marine Service’s ability to deliver continuous, state-of-the-art information on the ocean surface.
