Sentinel-1D and Ariane 6 Ready for Liftoff
The Sentinel-1D satellite now stands on the launch pad at Europe’s Spaceport in French Guiana, prepared for liftoff aboard the Ariane 6 launcher. This milestone marks its entry into the Sentinel-1 mission, part of the Copernicus Earth observation programme.
The mission aims to expand radar imaging capabilities, offering a detailed view of Earth’s dynamic environment. Its advanced synthetic aperture radar (SAR) system can capture high-resolution images day and night, in all weather conditions, ensuring uninterrupted data delivery for global users.

Purpose and Applications
Sentinel-1D’s data supports a wide range of users worldwide — from disaster relief crews to climate researchers. The continuous stream of radar images helps monitor environmental changes and respond quickly to emergencies.
- Arctic sea-ice monitoring and iceberg tracking
- Mapping of sea ice and glacier movement
- Marine surveillance, including oil-spill detection and ship monitoring
- Observation of illegal fishing operations
- Detection of ground deformation from earthquakes, subsidence and volcanic activity
- Mapping of forests, soil, and water resources
Mission Impact
By joining the Sentinel-1 constellation, Sentinel-1D enhances the continuity and reliability of Copernicus services. The additional satellite will improve revisit times and data frequency, benefiting both environmental monitoring and security operations across the globe.
Author’s summary: Sentinel-1D’s launch with Ariane 6 strengthens the Copernicus programme by enhancing radar coverage for real-time Earth observation and swift global response.
