Planetary Science Archive
The Planetary Science Archive is the central repository for all scientific and engineering data returned by the European Space Agency's Solar system missions: currently Giotto, Huygens, Mars Express, Rosetta, SMART-1, and Venus Express, as well as several ground-based cometary observations. It uses NASA's Planetary Data System standards as a baseline for the formatting and structure of all data contained within the archive. All of the data sets are peer reviewed and undergo an additional internal validation procedure.
