Through the Third Party Missions programme, ESA offers data from a wide range of EO satellite missions developed and operated by other agencies.

What are Third Party Missions?

The Third Party Missions (TPM) programme has been operating for over 45 years and consists of a series of satellites specifically focused on Earth Observation which are owned by commercial and public organisations worldwide.

The programme currently comprises over 50 missions with data sourced from more than 60 instruments which is supplied to users for research and development purposes. ESA promotes the availability of these third party datasets so that they are offered through a single programme for ease of access.

Some examples of Third Party Missions, that are currently operational, include Pléiades Neo, Spire, GHGSat, ICEYE and PlanetScope.
