On Tuesday November 4, 2025, at 6:03 p.m. Kourou time (9:03 p.m. UTC, 10:03 p.m. CET) Copernicus Sentinel-1D lifted off from Europe’s Spaceport in Kourou, French Guiana, onboard an Ariane 6 launcher.
Sentinel-1D will ensure the continuous full operational capacity of the Sentinel 1 mission by replacing the Sentinel-1A satellite, which was launched in 2014.
Like its predecessor satellites, Sentinel-1D will monitor our planet day and night, under all weather conditions. Its dedicated radar instrument can detect oil spills, illegal maritime activities, floods, icebergs, and sea ice concentration, among others.
EMSA will integrate Sentinel-1D into its mission portfolio, supporting the monitoring of pollution at sea under the CleanSeaNet service.
Copernicus is the Earth Observation component of the European Union Space Programme, of which the European Commission is the project manager and owner.
