Europe’s Copernicus program notched a significant milestone recently with the successful launch of Sentinel-1D, the final satellite in the first generation of the Sentinel-1 radar Earth-observing mission. The satellite lifted off on Nov. 4, 2025 aboard an Ariane 6 rocket.
With Sentinel-1D now in space, Europe has reinforced its capacity to monitor the planet independently and continuously, regardless of weather conditions or the availability of daylight.
