MISSIONS
Explore the European Space Agency's Earth Observation satellite missions. Learn all about ESA's dedicated Earth Explorers or collaborations with other agencies through the Third Party Missions programme.
Mission - Third Party Missions
WorldView-4
WorldView-4 was an imaging and environment-monitoring satellite from Maxar of the United States, which offered very high resolution imagery.
Mission - Third Party Missions
TerraSAR-X and TanDEM-X
The TerraSAR-X and TanDEM-X satellites feature a unique geometric accuracy that is unmatched by any other spaceborne sensor.
