Sentinel-2 is a satellite mission under the Copernicus program by the European Space Agency (ESA) and the European Commission. It consists of 2 optical imaging satellites. This advanced satellite mission provides crucial insights into our planet, aiding in environmental monitoring, climate change assessment, agriculture management, and more.

1. Mission Objectives and Applications

  • Sentinel-2’s primary objective is to provide multispectral Earth imagery from space.
  • Two identical satellites are employed, ensuring a continuous stream of data.
  • Sentinel-2 is part of the GMES program, jointly run by the European Commission (EC) and European Space Agency (ESA), for global land observation.

2. Technical Specifications

  • Sentinel-2 satellites are equipped with advanced multispectral cameras operating in various spectral bands.
  • Spatial resolution ranges from 10 to 60 meters with 13 bands – 3 visible bands with 10 m resolution, 1 visible band with 60 m resolution, 3 NIR bands with 20 m resolution, 6 SWIR bands with 60 m resolution.
  • Sentinel-2A was launched on the 23rd of June 2015 at French Guiana and Sentinel-2B was launched in March 2017 at French Guiana.
  • The approximate date of mission completion is 2038.
  • To meet the goal of frequent revisits and high mission availability, there’s a need for two satellites in space simultaneously, each with a 290 km wide swath using a single imaging instrument
  • Sentinel-2A and 2B will be replaced by Sentinel-2C and 2D in 2024 and 2025 due to their seven-year design life.

3. Observation Frequency

  • Those 2 operational satellites are used to reduce revisit time from 10 to 5 days, surpassing the revisit times of Landsat-7 and SPOT.

4. Open Access Data

  • Sentinel-2 data is openly accessible to the public, researchers, and governmental agencies.
  • This encourages collaboration and innovation in various fields.
