Introduction to the PSA
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 ExoMars 2016, Giotto, Huygens, Mars Express, Rosetta, SMART-1, and Venus Express, as well as several ground-based cometary observations.
All PSA data comply with NASA's Planetary Data System (PDS) standards. Since the founding of the PSA, the PDS Standards have evolved from version 3 to version 4. You can find out more about the archiving process, the standards and the differences between the versions here:
