The Copernicus Sentinel-1D satellite has joined the Sentinel-1 mission in orbit. Launch took place on 4 November 2025 at 22:02 CET (18:02 local time) on board an Ariane 6 launcher from Europe\u2019s Spaceport in French Guiana.<\/p>\n
The\u00a0Sentinel-1 mission\u00a0delivers high-resolution radar images of Earth\u2019s surface, performing in all weathers, day-and-night. This service is used by disaster response teams, environmental agencies, maritime authorities and climate scientists, who depend on frequent updates of critical data.<\/p>\n
Sentinel-1D will work in tandem with Sentinel-1C, flying in the same orbit but 180\u00b0 apart, to optimise global coverage and data delivery. Both satellites have a C-band synthetic aperture radar (SAR) instrument on board, which captures high-resolution imagery of Earth\u2019s surface. They are also equipped with Automatic Identification System (AIS) instruments to improve detection and tracking of ships. When Sentinel-1D is fully operational, it will enable more frequent AIS observations, including data on vessel identity, location and direction of passage, enabling precise tracking.<\/p>\n
Sentinel-1D was launched on Europe\u2019s heavy-lift rocket\u00a0Ariane 6\u00a0on flight designated VA265.\u00a0<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
