Sentinel-2

The Copernicus Sentinel-2 mission comprises a constellation of two polar-orbiting satellites placed in the same sun-synchronous orbit, phased at 180° to each other. It aims at monitoring variability in land surface conditions, and its wide swath width (290 km) and high revisit time (10 days at the equator with one satellite, and 5 days with 2 satellites under cloud-free conditions which results in 2-3 days at mid-latitudes) will support monitoring of Earth's surface changes.

For mission planning and updated coverage status information, see the Revisit and Coverage page.

This Sentinel-2 Mission Guide provides a high-level description of the mission objectives, satellite description and ground segment. It also addresses the related heritage missions, thematic areas and Copernicus services, orbit characteristics and coverage, instrument payload, and data products.

Copernicus Sentinel-2B MSI decontamination between 13 and 14 December 2021

06 December 2021

A routine decontamination activity of the Copernicus Sentinel-2B MSI is planned to take place over a continuous period of 24 hours between 09:00 UTC on 13 December 2021 and 09:00 on 14 December (corresponding approximately to the period between absolute orbits 24915 to 24929). During this temporal window no MSI acquisitions will take place.

Correlated calibration activities will be performed around the decontamination period, which will further affect the nominal acquisition plan between 00:10 UTC on 13 December and 07:40 on 15 December.
