  • How ESA's Third Party Missions support European commercialisation

    ESA's Third Party Missions programme consists of Earth observation satellites that are owned by commercial and public organisations around the world.

  • How much data may I request in a Project Proposal?

    Access to some restrained data collections distributed by ESA require submission of a Project Proposal. These collections are typically for Third Party Missions when the data provider can only offer a limited amount of data.

  • A Satellite Perspective of Icebergs A-68 and B-46 in Antarctica, 2018

    See the transformations of Iceberg B-46 and Iceberg A-68 through Proba-V satellite images.

  • Explore sample data products from Third Party Missions

    ESA’s Third Party Missions programme consists of over 50 satellite missions from commercial and public organisations worldwide.

  • Go-to guide to Third Party Mission data offering

    ESA’s latest Third Party Missions Data Access Guide has been published, providing technical details and information on available data collections for all current or past Third Party Missions.

  • Sample data products from ESA’s Third Party Missions

    Samples of data products from a range of Third Party Missions are now available to download, offering a preview of what these missions provide.

  • How to find the geographical and temporal coverage of the ESA TPM archive collections

    Explore the ESA TPM archive collections, containing Earth Observation data from international partners, and learn how to discover their geographical and temporal coverage for research and pre-operational applications.

  • What are the Terms of Applicability?

    Essential information about data ordering, accessibility conditions, and distribution constraints for TPM EO data.

  • How to use space data to probe humankind’s ancient past

    Data disseminated by ESA’s Third Party Missions (TPM) programme are enabling archaeological investigations that could help to unravel the mysteries of past societies and cultures.

  • Monitoring the health of wheat crops from space

    Very high resolution space data can be used to improve the detection of a plant disease that impacts a major global cereal crop.

  • PROBA-V’s companion explores low-cost remote sensing

    With the launch of PROBA-V’s Companion CubeSat (PV-CC), ESA supports a future where clusters of cheaper, small satellites could complement full-scale missions for Earth observation.

  • Commercial space data help to regreen grasslands in Africa

    Commercial satellite imagery made available through ESA’s Third Party Missions programme is guiding an ambitious community-focused initiative to regrow natural grasslands in Sub-Saharan Africa.

  • Meet the Quality Assurance for EO Team

    The Quality Assurance For Earth Observation (also known as QA4EO) Service began its operations on 1 November 2019, providing support to the Data Quality and Algorithms Management Office at ESRIN, within the Sensor Performance, Processing and Algorithm section.

  • Meet one of ESA's first Africa Programme Research Fellows

    Research Fellow, Dr Gladys Mosomtai, from the International Centre of Insect Physiology and Ecology (icipe), works on applying Earth observation data to better understand the spread of infectious disease in livestock, in Kenya.

  • PROBA-V data improve surface albedo products in Africa

    As ESA’s PROBA-V satellite marks its 10-year launch milestone, data tasked during the mission’s lifetime are still being used to assess changes in land cover.

  • PROBA-V ‘Collection 2’ - Reprocessed Dataset available

    The improved PROBA-V data (Collection 2) has been released. Data is available via the PROBA-V MEP and Terrascope platforms so users can freely exploit the data using Virtual machines, Jupyter Notebooks, and the new viewing application.

  • International collaboration: Summarising ESA’s Third Party Missions

    ESA’s Third Party Missions programme consists of more than 50 missions from around the world. Learn more about the Third Party Missions in this video.

  • Global understanding of Earth's land surfaces greatly boosted by satellite data

    ESA perform land surface monitoring with a range of instruments onboard satellites acquiring optical and radar data. Collections of data from these missions are freely available for research purposes.

  • Satellites reveal changes to Earth’s icy zones

    ESA’s Earth observation activities are helping scientists investigate the influence of climate change on widespread ice-losses across the planet.

  • SkySat ESA archive

    The SkySat ESA archive collection consists of SkySat products requested by ESA supported projects over their areas of interest around the world and that ESA collected over the years. The dataset regularly grows as ESA collects new products. Two different product types are offered, Ground Sampling Distance at nadir up to 65 cm for panchromatic and up to 0.8m for multi-spectral.

Atmospherically corrected Surface Reflectance product. Analytic - orthorectified, multispectral BGRN. Radiometric corrections applied to correct for any sensor artifacts and transformation to top-of-atmosphere radiance. Analytic DN - orthorectified, multispectral BGRN, uncalibrated digital number imagery product Radiometric corrections applied to correct for any sensor artifacts Panchromatic - orthorectified, radiometrically correct, panchromatic (PAN) Panchromatic DN - orthorectified, panchromatic (PAN), uncalibrated digital number imagery product The Ortho Collect product is created by composing SkySat Ortho Scenes along an imaging strip. The product may contain artifacts resulting from the composing process, particular offsets in areas of stitched source scenes. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service. As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.
