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 - Earth Explorers
Aeolus
The Aeolus mission provides global observations of wind profiles from space to improve the quality of weather forecasts, and to advance our understanding of atmospheric dynamics and climate processes.
Mission - Earth Explorers
CryoSat
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.
Mission - Earth Explorers
SMOS
The Soil Moisture and Ocean Salinity (SMOS) mission is dedicated to making global observations of soil moisture over land and salinity over oceans.
Mission - Third Party Missions
PROBA-1
PROBA-1 is a technology demonstration satellite that later became an operational Earth observation mission.
Mission - Heritage Missions
Envisat
Envisat was ESA's successor to ERS. Envisat carried ten instruments aboard for a wide range of Earth observing fields. The mission was operational from 2002 to 2012.
Mission - Heritage Missions
ERS
The ERS programme was composed of two missions, ERS-1 and ERS-2, which together observed the Earth for 20 years, from 1991 to 2011.
Mission - Third Party Missions
TanSat
The TanSat mission is one of the Earth Observation projects managed by the Ministry of Science and Technology of China and is dedicated to detecting and monitoring carbon dioxide in the atmosphere.
Mission - Third Party Missions
Vision-1
Launched on 16 September 2018, Vision-1 offers orthorectified products with resolution up to 87 cm in panchromatic mode and 3.48 in multispectral mode as standard.
Mission - Third Party Missions
Pléiades Neo
Pléiades Neo is a very high resolution optical constellation of two identical satellites phased at 180° from each other.
Mission - Third Party Missions
GHGSat
The GHGSat mission is dedicated to measuring emissions of greenhouse gases.
Mission - Copernicus Sentinels
Copernicus Sentinel-5P
The Copernicus Sentinel-5 Precursor mission is the first Copernicus mission dedicated to monitoring our atmosphere.
Mission - Copernicus Sentinels
Copernicus Sentinel-3
Copernicus Sentinel-3 is an European Earth Observation satellite mission developed to support Copernicus ocean, land, atmospheric, emergency, security and cryospheric applications.
Mission - Copernicus Sentinels
Copernicus Sentinel-2
The Copernicus Sentinel-2 mission comprises a constellation of two polar-orbiting satellites placed in the same sun-synchronous orbit, phased at 180° to each other.
Mission - Third Party Missions
GOSAT Series
The GOSAT series is composed of two environment-monitoring satellites developed by JAXA dedicated to the observation of greenhouse gases.
Mission - Third Party Missions
NOAA POES
NOAA's AVHRR sensor is carried on the POES mission, a constellation of polar orbiting weather satellites.
Mission - Third Party Missions
GOSAT-2
GOSAT-2 (Greenhouse gases Observing Satellite-2) is a JAXA satellite dedicated to the observation of greenhouse gases.
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
GRACE
GRACE stands for the Gravity Recovery and Climate Experiment and was a part of the international Earth Observing System (EOS) series of satellites.
