Copernicus Sentinel-1B anomaly (4th update)

28 January 2022

Following the previous news on the Sentinel-1B anomaly that occurred on 23 December 2021, very detailed investigations related to the satellite power system’s affected unit are on-going, and will require some additional weeks.

The objective is to identify the root cause of the anomaly and then possibly perform new attempts for the reactivation of the unit.

The satellite remains under control, the thermal control system works properly and the regular orbit control manoeuvres are routinely performed.

We apologise for the inconvenience caused.
