News

Following the previous news on the Sentinel-1B anomaly that occurred on 23 December 2021, further attempts to reactivate the proper functioning of the satellite power system’s affected unit were executed, but were not successful.

All necessary investigations to identify the root cause and possibly fix the issue are on-going.

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

We apologize for the inconvenience caused.

Due to Copernicus Sentinel-3B orbit correction manoeuvre, SLSTR IR products degradation is expected for sensing time from 12/01/2022T08:18:51 to 12/01/2022T08:28:27

Due to Copernicus Sentinel-3A orbit manoeuvres, SLSTR and OLCI products degradation is expected for the following sensing times:

- from 07/01/2022T00:04:18 to 07/01/2022T00:17:36

- from 07/01/2022T02:06:48 to 07/01/2022T02:17:25

Following the previous news on the Sentinel-1B anomaly that occurred on 23 December 2021, the resuming of the operations was carefully prepared including the on-board configuration changes preventing the anomaly to occur again.

However, during the preparation of the recovery operations, it became clear that the initial anomaly was a consequence of a potential serious problem related to a unit of the power system of the Sentinel-1B satellite. The operations performed over the last days did not allow to reactivate so far a power supply function required for the radar operations.

Further investigations to identify and remedy the root cause will be performed over the next days.

We apologize for the inconvenience caused.

Users are informed that from 08:00 to 18:00 UTC of the 04th of January 2022 there will be a maintenance activity on the Open Access Hub (SciHub and APIHub).
During the maintenance window user might experiencing short download interruptions.

We apologize for any inconvenience this might cause to your activities.

Copernicus Sentinel-1A was unavailable between 24/12/2021 19:32 UTC and 25/12/2021 12:08 UTC, due to an onboard software anomaly.

No SAR data were acquired during this period. Data acquisitions taking place indicatively within 2 hours before this period may have been affected.

We apologize for the inconvenience caused.

Copernicus Sentinel-1B is unavailable since 23 December 2021 at 06:53 UTC, no data are being generated.

Following the related news of 23 December 2021, detailed investigations have taken place. Specific actions will be performed over the next days to implement an onboard configuration change that will prevent the re-occurrence of the anomaly (that could result in satellite safety risks).
This requires simulations and system validation activities on ground, before upload to the satellite.

This satellite unavailability period may potentially last up to 2 weeks, however all efforts to shorten this unavailability are being deployed.

Further news will be issued on the recovery operations, we apologize for the inconvenience caused.

Copernicus Sentinel-1B is unavailable since 23 December 2021 at 06:53 UTC, no data are being generated.
An anomaly occurred onboard, that will require some time for detailed analyses.
The satellite is in a nominal mode, the SAR has been temporarily switched off. Further news will be issued on the recovery operations.
We apologize for the inconvenience caused.

Meet Anja Stromme

21 December 2021

In this 'mini pill', ESA's Sentinel-3 Mission Manager, Anja Stromme, describes what she enjoys most about the mission.

We are pleased to report that the Sentinel-5P Products Algorithm Laboratory (S5P-PAL) system provides a reprocessed consistent Sentinel-5P (S5P) TROPOMI NO2 product (processed with the same processor – version 2.3.1) for the time period 1 May 2018 to 14 November 2021.

This data set has been generated to allow consistent data analysis (e.g. trends in COVID-19 impact on air pollution) over the above mentioned time period.

This NO2 reprocessed dataset is made available through the S5P-PAL data portal at: https://data-portal.s5p-pal.com
