A Collision Avoidance Manoeuvre executed on Sentinel-1A on 10 May 2025 induced an unrecoverable loss of data. The impact is fully reported in the Sentinel Operations Dashboard Events Page.
We apologize for the inconvenience this may have caused.

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.
