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.

  • 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.

  • Swarm Product Data Handbook

    The Swarm Product Data Handbook provides a detailed description of Level 1b and Level 2 products derived from Swarm data.

  • Swarm

    Swarm is dedicated to creating a highly detailed survey of Earth’s geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of three identical satellites.

  • SPOT

    The SPOT (from French "Satellite pour l'Observation de la Terre") series of missions has been supplying high-resolution, wide-area optical imagery since 1986.

  • Spire

    Spire Global's constellation of Lemur nanosatellites offer satellite-based maritime, aviation and weather tracking.

  • SMOS

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

  • 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.

  • PROBA-1

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

  • Odin

    Odin is an atmosphere-studying satellite mission from Sweden, Canada, France and Finland.

  • OceanSat-2

    OceanSat-2 which was launched on 23 September 2009 and ceased operations in December 2022 provided 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.

  • NOAA POES

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

  • 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.

  • MetOp

    MetOp is a mission dedicated to improving weather forecasts and monitoring Earth's climate.

  • Meteosat Second Generation

    The ESA Meteosat Second Generation (MSG) programme, started in 1994, is composed of four satellites.

  • 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.

  • GRACE

    GRACE stands for the Gravity Recovery and Climate Experiment and was a part of the international Earth Observing System (EOS) series of satellites.

  • GOSAT-2

    GOSAT-2 (Greenhouse gases Observing Satellite-2) is a JAXA satellite dedicated to the observation of greenhouse gases.

  • GOSAT-1

    GOSAT-1 is a Japanese environment-monitoring satellite

  • GOSAT Series

    The GOSAT series is composed of two environment-monitoring satellites developed by JAXA dedicated to the observation of greenhouse gases.

  • GHGSat

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