On November 4, 2025 at 6:03 p.m. local time in French Guiana (9:03 p.m. UTC, 10:03 p.m. CET), Arianespace plans to launch the Copernicus Sentinel-1D satellite aboard Ariane 6 from Europe's Spaceport. Mission VA265 marks the launcher's third commercial flight and will target Sun-synchronous orbit near 693 km.

Separation is expected about 34 minutes after liftoff. The mission underscores Europe's drive for autonomous access to space and Arianespace's role in enabling space capabilities that benefit life on Earth.

Sentinel-1D is part of Copernicus, the Earth observation component of the European Union's Space Programme, managed and funded by the EU with a partial contribution from ESA. Copernicus delivers continuous, free, reliable Earth observation data and services for public authorities, businesses, and citizens worldwide.

Carrying advanced radar, Sentinel-1D will supply all-weather, day-and-night imagery to monitor sea ice, track icebergs and glaciers, map subsidence, and detect oil spills. Thales Alenia Space, a joint venture of Thales (67%) and Leonardo (33%), is the prime contractor; the satellite arrived in French Guiana on September 11, 2025.
