Sentinel 1-D Joins European Copernicus Satellite Network
Launched from Kourou aboard an Ariane 6 rocket, the Sentinel 1-D satellite has become part of the European Copernicus constellation, designed to observe the Earth continuously, day and night, regardless of weather conditions.
Advanced Observation Capabilities
Operated by the European Space Agency (ESA) from Darmstadt, Germany, Sentinel 1-D uses synthetic aperture radar (SAR), which allows it to capture detailed images even in complete darkness or through cloud cover. Positioned at an altitude of 700 kilometers, it monitors natural phenomena such as volcanic eruptions, landslides, and floods.
Scientific and Environmental Impact
This satellite offers scientists critical data on landform changes, deforestation, and sea-level rise. Dominique Gilliéron, head of Earth observation projects at ESA, highlights Sentinel 1-D’s ability to measure ground deformation, oversee illegal fishing, and evaluate agricultural yield.
"This type of radar satellite sees day and night and through clouds. It continuously documents the state of the planet," explains Dominique Gilliéron.
Copernicus Program Overview
Since its launch in 2014, Copernicus has become the world's premier environmental monitoring initiative, with Sentinel 1-D enhancing its capability to provide constant, reliable global data.
Author's summary: Sentinel 1-D, equipped with synthetic aperture radar, enriches the European Copernicus mission by delivering all-weather, day-and-night Earth monitoring to support environmental and climate science.
