On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Unfortunately, despite all concerted efforts, ESA and the European Commission announced on 3 August 2022 that it is the end of the mission for Sentinel-1B.
This retirement will impact the availability of new change detection updates for some existing Global Change Monitoring users and will further restrict Capella's ability to provide new change detection analytics to new users in certain areas. Areas of Interest reliant on Sentinel 1B data can be found by viewing the Sentinel 1 Acquisition Segments: https://sentinels.copernicus.eu/web/sentinel/missions/sentinel-1/observation-scenario/acquisition-segments
Data collection on the Sentinel 1A satellite is not impacted and Global Change Monitoring will continue to be available for much of the Earth.
2022-08-03 | The European Space Agency and the European Commission announced the end of the mission for the Copernicus Sentinel-1B satellite. ESA’s Director of Earth Observation Programmes, Simonetta Cheli, stated, “Unfortunately, we have to announce the end of the mission for the Copernicus Sentinel-1B satellite. The conclusion drawn by the Anomaly Review Board is that it is impossible to recover the 28V regulated bus of the satellite’s C-band synthetic aperture radar antenna power supply unit, which is needed to provide power to the radar electronics." https://www.esa.int/Applications/Observing_the_Earth/Copernicus/Sentinel-1/Mission_ends_for_Copernicus_Sentinel-1B_satellite
2022-4-22 15:14 UTC | Copernicus continues to report that "Sentinel-1 users should assume a long-term unavailability of data provision (several months). It is however too early to consider a permanent unavailability of Sentinel-1B. We apologize for the inconvenience caused."

2022-1-28 16:08 UTC | Copernicus reported that "very detailed investigations related to the satellite power system’s affected unit are on-going, and will require some additional weeks." https://scihub.copernicus.eu/news/News00993
2022-1-17 08:16 UTC | Copernicus reported that planned fixes have not been successful and that "All necessary investigations to identify the root cause and possibly fix the issue are on-going." https://scihub.copernicus.eu/news/News00985
2022-1-10 07:10 UTC | Copernicus reported that further investigation into the anomaly is required. There is currently no forecast date of return to operation. https://scihub.copernicus.eu/news/News00980
2021-12-25 08:58 UTC | Copernicus reported that "this satellite unavailability period may potentially last up to 2 weeks, however all efforts to shorten this unavailability are being deployed." https://scihub.copernicus.eu/news/News00977
2021-12-24 06:43 UTC | Copernicus reported an anomaly on the Sentinel 1B SAR satellite that stopped SAR data acquisition since 23 December 2021 at 06:53 UTC. https://scihub.copernicus.eu/news/News00976
