In addition to data provided by the Sentinel satellites, the Copernicus Contributing Missions play a crucial role, delivering complementary data to ensure that a whole range of observational requirements is satisfied. The existing or planned Contributing Missions include commercial missions from EU Member States or Copernicus Participating States, commercial Very High Resolution (VHR) optical and radar mission operators, and other emerging European New Space mission operators that make some of their data available for Copernicus.
