The European Space Agency’s Planetary Science Archive (PSA) is the central repository for all scientific and engineering data returned by ESA’s planetary missions: currently ExoMars 2016, Giotto, Huygens, Mars Express, Rosetta, SMART-1, and Venus Express, as well as several ground-based cometary observations.
All data on the PSA are free to download and use. Please acknowledge the Principal Investigator(s) as well as the ESA Planetary Science Archive when making a publication using the data you download. Instructions can be found here.
