An anomaly affecting the Optical Communication Payload of Sentinel-2A has resulted in the loss of approximately 30% of the data sensed between 07 and 08 May 2025.
The affected acquisitions were not successfully downlinked and are therefore permanently unavailable (datatakes impacted: 51560-3, 51562-1, 51562-2, 51566-1, 51566-2, 51568-1, 51569-1, 51569-2, 51570-1, 51571-1, 51571-2, 51571-3).
Additional data acquired in the following hours may also be impacted. Mitigation measures are being implemented to address the root cause and prevent recurrence.
A follow-up communication will be issued once the anomaly is resolved and normal operations are restored.
We apologise for the inconvenience caused.
