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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Copernicus Sentinel-1

    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.

  • WorldView-4

    WorldView-4 was an imaging and environment-monitoring satellite from Maxar of the United States, which offered very high resolution imagery.

  • NOAA POES

    NOAA's AVHRR sensor is carried on the POES mission, a constellation of polar orbiting weather satellites.

  • SkySat

    SkySat is a constellation of high-resolution Earth imaging satellites from the commercial company Planet Labs.
