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.
  • 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.

  • SMOS

    The Soil Moisture and Ocean Salinity (SMOS) mission is dedicated to making global observations of soil moisture over land and salinity over oceans.

  • Biomass

    The objective of the Biomass mission is to determine the global distribution of forest biomass.

  • Aeolus

    The Aeolus mission which was launched into space on 22 August 2018 and was retired on 30 April 2023, provided 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.

  • PROBA-V

    The PROBA-V mission provides multispectral images to study the evolution of the vegetation cover on a daily and global basis.

  • PROBA-1

    PROBA-1 is a technology demonstration satellite that later became an operational Earth observation mission.

  • 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.

  • 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.

  • HydroGNSS

    HydroGNSS is a microsatellite mission, which is part of the Scout framework, and consists of a GNSS-R (Global Navigation Satellite System Reflectometry) constellation that primarily addresses land. Scout missions are a new element in ESA's Earth Observation FutureEO Programme.

  • NovaSAR-1

    Launched on 16 September 2018, NovaSAR-1 features an S-band synthetic aperture radar (SAR) instrument offering a variety of modes with different resolutions and swath widths.

  • MOS-1/1B

    MOS-1 and 1B, Japan’s first marine observation satellites, were designed to monitor ocean currents, sea surface temperature, atmospheric water vapour, ocean chlorophyll levels, precipitation, and land vegetation.

  • FSSCat

    The FSSCat mission was an innovative concept that consisted of two federated 6-Unit Cubesats, called ³Cat-5/A and ³Cat-5/B, which operated in support of the Copernicus Land and Marine Environment services.

  • 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.

  • 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.

  • Pléiades Neo

    Pléiades Neo is a very high resolution optical constellation of two identical satellites phased at 180° from each other.

  • SAOCOM

    The SAOCOM (SAtélite Argentino de Observación COn Microondas) satellite series represents Argentina's approved polarimetric L-band SAR constellation of two spacecraft. It's objective is to provide an effective Earth observation and disaster monitoring capability.

  • COSMO-SkyMed Series

    COSMO-SkyMed (COnstellation of small Satellites for the Mediterranean basin Observation) Series aims to provide global Earth observation that can be repeated several times a day in all-weather conditions.

  • COSMO-SkyMed Second Generation

    COSMO-SkyMed Second Generation is at the forefront of radar technology, will ensure improvements and guarantee continuity with the First Generation CSK satellites, preserving the high quality and the highest precision features, both required for the interferometric activities.

  • GHGSat

    The GHGSat mission is dedicated to measuring emissions of greenhouse gases.

  • Copernicus Sentinel-5P

    The Copernicus Sentinel-5 Precursor mission is the first Copernicus mission dedicated to monitoring our atmosphere.
