Sentinel-1B is a European radar imaging satellite launched on 25 April 2016. It is the second of two satellites in the Sentinel-1 constellation, part of the European Union's Copernicus programme on Earth observation. The satellite carries a C-SAR sensor, capable of providing high-resolution imagery regardless of weather conditions.

Satellite made its first observation on 28 April, capturing 250 km wide image of Austfonna glacier on Svalbard.^[6]

Beginning on December 23, 2021, the spacecraft experienced an anomaly which resulted in a loss of data transmission. On January 10, 2022, the European Space Agency confirmed online that a power issue was the root cause of the issue and that initial attempts to fix it had failed. The agency confirmed that efforts to restore spacecraft capabilities would continue.^[7]
