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 - Heritage Missions
GRACE
GRACE stands for the Gravity Recovery and Climate Experiment and was a part of the international Earth Observing System (EOS) series of satellites.
Mission - Heritage Missions
JERS-1
The overall objectives of JERS-1 (Japanese Earth Resources Satellite) were the generation of global data sets with SAR and OPS sensors aimed at surveying resources, establishing an integrated Earth observation system
Mission - Heritage Missions
KOMPSAT-2
KOMPSAT-2 (Korea Multi-Purpose Satellite-2), also known as Arirang-2, was developed by KARI (Korea Aerospace Research Institute) to continue the observation programme of the KOMPSAT-1 mission.
Mission - Third Party Missions
OceanSat-2
OceanSat-2 provides service continuity for the operational users of the OCM (Ocean Colour Monitor) instrument launched in 1999 on board the predecessor IRS-P4/OceanSat-1 mission.
Mission - Third Party Missions
Odin
Odin is an atmosphere-studying satellite mission from Sweden, Canada, France and Finland.
Mission - Third Party Missions
SCISAT-1
SCISAT-1 is designed to make observations of Earth's atmosphere and its main instruments are an optical Fourier transform infrared spectrometer and an ultraviolet spectrophotometer.
Mission - Heritage Missions
Seasat
On board Seasat was the first-ever space-borne synthetic aperture radar (SAR) system for science applications.
Mission - Heritage Missions
SPOT 2
SPOT 2, like all the SPOT missions, was aimed at supplying high-resolution, wide-area optical imagery.

SPOT 7
SPOT 7 (also known as Azersky), like all of the other SPOT missions, was aimed at supplying high-resolution, wide-area optical imagery.
Mission - Earth Explorers
EarthCARE
EarthCARE will examine the role clouds and aerosols play in trapping infrared radiation emitted from Earth's surface.
Mission - Earth Explorers
FLEX
The FLEX mission will provide global maps of vegetation fluorescence, which can be converted into an indicator of photosynthetic activity.
Mission - Meteorological Missions
Meteosat Second Generation
The ESA Meteosat Second Generation (MSG) programme, started in 1994, is composed of four satellites.
Mission - Meteorological Missions
MetOp
MetOp is a mission dedicated to improving weather forecasts and monitoring Earth's climate.
Mission - Third Party Missions
Aura
NASA's Aura mission studies the chemistry and dynamics of Earth's atmosphere from the ground through the mesosphere.
Mission - Third Party Missions
ICEYE
As of June 2023, 27 X-band Synthetic Aperture Radar (SAR) satellites have been launched for the ICEYE constellation. This enables all-weather Earth observation.
