Meeting #1

PSA Introduction/ Context

PSA UG #1  July 2 - 3, 2013  ESAC

esa science data archiving
ESA Science Data Archiving
  • 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, …
psa definition and purpose
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.

psa successes
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 SREand PSA is a major partner in all European and worldwide initiatives
    • IPDA
    • EuroPlanet

psa usage
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 actionto provide access statistics for each instrument.

>85% of data access is currently through the FTP interface
