As the first mission of the @CopernicusEU Programme, Sentinel-1 comprises two satellites orbiting 180 degrees apart, providing all-weather, day-and-night imagery of Earth’s surface, designed, built, launched and flown by @ESA.
The partner satellite, Sentinel-1A, remains healthy in orbit, continuing to deliver high-quality radar images for a multitude of applications.
Our focus is on fast-tracking the launch of Sentinel-1C.
