Explore the European Space Agency's Earth Observation satellite missions. Learn all about ESA's dedicated Earth Explorers or collaborations with otheragencies through the Third Party Missions programme.
Swarm is dedicated to creating a highly detailed survey of the Earth’s geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of three identical satellites.
CryoSat determines variations in the thickness of continental ice sheets and marine ice cover. Europe's first ice mission is an advanced radar altimeter specifically designed to monitor the most dynamic sections of Earth's cryosphere.
ESA's Gravity field and Ocean Circulation Explorer (GOCE) mission mapped Earth's geoid very accurately, opening a window into Earth's interior structure as well as the currents circulating within the depths of its oceans.
The Copernicus Sentinel-1 mission comprises a constellation of two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar imaging, enabling them to acquire imagery regardless of the weather.
