Ariane 62 • Sentinel 1D

Ariane 62 • Sentinel 1D

Arianespace will launch an Ariane 6 rocket on a mission designated VA265, to carry the Sentinel 1D Earth observation satellite for ESA into orbit. It will be part of the Copernicus program. The new satellite will replace Sentinel 1A, which is well beyond its planned lifetime. The mission was switched from Vega C to Ariane in January 2025. Ariane 6 will fly in the Ariane 62 configuration, using 2 solid rocket boosters. - Based on a Prima platform, developed by Thales Alenia Space for the Italian Space Agency, Sentinel 1D will weigh 2285kg at launch and will look at the Earth in swaths up to 700km with a ground resolution of between 5 and 25m according to the selected operative mode. It will carry a C-band Synthetic Aperture Radar (SAR), based on Thales Alenia Space's key technologies such as the Transmit-Receive modules inside the active antenna. Sentinel 1D also features a new Automatic Identification System (AIS), for use by sea-faring ships on Earth to avoid collisions when they are out of range of land-based radar systems. - Delayed from January and June. Moved forward from November. Delayed from late October. Webcast: https://www.arianespace.com/road-to-space/
