1. Planetary Science Archive PSA User Group Meeting #1 PSA UG #1  July 2 - 3, 2013  ESAC PSA Introduction / Context

2. PSA-UG  2-3 July 2013  Slide 2 Science data is the final “product” of the mission Much longer lifetime than the mission itself Requirements for long term preservation Prior to 1998, ESA Science Archives “given” to the community No insurance of long term availability Loss of image for ESA in the scientific community Since 1998 (ISO), ESA Science Archives kept at ESAC Ensuring long term preservation and availability Higher ESA image in the scientific community –ESAC Centre of Scientific Excellence Some similar concepts across archives On-line, search / view / select / download, curation, statistics, … ESA Science Data Archiving

3. PSA-UG  2-3 July 2013  Slide 3 PSA Definition and Purpose The Planetary Science Archive (PSA) 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 main 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.

4. PSA-UG  2-3 July 2013  Slide 4 Planetary Science Archive Available since March 2004: http://archives.esac.esa.int/psa Active development Datasets received from PI teams Peer-reviewed by independent team Internally validated before ingestion into the PSA Around 20TB of data on hard disks Access services (details this afternoon) Advanced search interface Map based query for MEX FTP Browser (not searchable) Machine interface (PAIO)

5. PSA-UG  2-3 July 2013  Slide 5 PSA Successes Prior to 2004 : ESA missions data (Giotto) in CDROMs in a cupboard @ ESTEC Today : PSA @ ESAC is a single entry point to all ESA planetary science data Seen now as the “European” PDS Datasets are peer-reviewed Datasets are PDS compliant ESA SRE and PSA is a major partner in all European and worldwide initiatives IPDA EuroPlanet

7. PSA-UG  2-3 July 2013  Slide 7 PSA Usage Some basic PSA usage statistics follow, generated via our internal statistics tool We have also implemented statistics for access via the ftp links on the web site. This is an interim solution to an action to provide access statistics for each instrument. >85% of data access is currently through the FTP interface
