Explore ESA's Planetary Science Archive!
The European Space Agency's Planetary Science Archive (PSA) is the central repository for all
scientific and engineering data returned by ESA's Solar System missions: currently
Venus Express, as well as
several ground-based cometary observations.
The PSA uses NASA's Planetary Data System standards as a baseline for the formatting and
structure of all data contained within the archive. Learn more...
