The Sentinel-1B radar satellite, launched in April 2016 by a Russian Soyuz-2 rocket from the Kourou launch site, has failed, and troubleshooting is underway. About it reported on the website of the European program Copernicus.
No data has been received from the spacecraft to Earth since December 23, 2021. “The initial anomaly was determined to be the result of a potentially serious problem with the Sentinel-1B power grid,” Copernicus said in a statement.
Satellites of the Copernicus system, in particular, Sentinel-1А and Sentinel-1B, have been repeatedly used to monitor the territory of Russia.

In July 2021, the Defense Blog wrote that Russian radars located in the Rostov region near the border with Ukraine “distorted” images taken by the European Sentinel-1 satellite.
In November 2020, the Covert Shores blog published “distorted” Sentinel-1 images of Russian warships in the Barents Sea, noting that publicly available Sentinel-1 images can be used to locate ground or surface radars.
