Sentinel-1B satellite mission ends

Sentinel-1 Satellite

The European Space Agency announced today that efforts to repair the failed C-band SAR sensor onboard the Sentinel-1B satellite have not been successful. Therefore, the mission has been terminated. The satellite will be de-orbited starting after the Sentinel-1C satellite has been launched and becomes operational, sometime during the third quarter of 2023.
