Sentinel-1 is the first of the Copernicus Programme satellite constellations conducted by the European Space Agency. The mission was originally composed of a constellation of two satellites, Sentinel-1A and Sentinel-1B, which shared the same orbital plane. Two more satellites, Sentinel-1C and Sentinel-1D are in development. Sentinel-1B was retired following a power supply issue on December 23, 2021, leaving Sentinel-1A the only satellite of the constellation currently operating. Sentinel-1C is currently planned to launch in the final quarter of 2024.
