2. Page 2 Introduction to the ESA PSA PSA Definition and Purpose The Planetary Science Archive is the initiative, the setup, the process and the implementation to preserve data from ESA’s spacecraft to planetary bodies, as well as supplementary information acquired in laboratories or ground-based observatories. The prime objectives of the PSA are: to support the experimenter teams in the preparation for the spacecraft and ground-based long-term archives. to enable and ensure the (long-term) preservation of these archives. distribution of scientific useful data to the world wide scientific community. provision of supplementary data services aiming to maximize the usage of planetary mission data and ease the scientific data analysis.

3. Page 3 Introduction to the ESA PSA PSA and PDS The PSA is based in the Planetary Data System (PDS) standard. All the data distributed by and ingested to PSA have to be PDS compliant. All PSD compatible data formats conform to a unified standard format incorporating documentation, calibration, and raw and processed data files. The format distinguishes:  Data files. At this level each file will have a PDS label either appended to the beginning of the file or in a separate but proximate file.  Meta-data files. At the intermediate level are files which describe the circumstances and parameters of the data collection. These files are called “catalog objects” or just “catalog” files.  Volume/Dataset Description files. These files are included on any distribution medium intended to be an entire, self-contained archive. The volume description files detail the organization of the data in the archive and any additional documentation. The PDS Standards are defined in the PDS Standards Reference Document. A Data Dictionary exists for the PDS and PSA which contains all the keywords and values permitted by the Standard.
