ESA Planetary Science Archive (PSA)

The Planetary Science Archive (PSA) archives digital data products from ESA’s planetary missions, and ground based observations supporting these planetary missions. The PSA is in contact with the science community to ensure that it is a valuable resource for scientists.

PSA is a multi-mission archive for all scientific and engineering data returned by ESA’s planetary missions. With a primary focus on scientifically related data sets, PSA provides a range of cross-mission and cross-instrument search and download services centralizing data access and resources for users wishing to use planetary data.

The PSA also ensures long-term preservation of ESA planetary missions’ data holdings and associated archives services during the legacy phases of these missions.

All PSA products are peer-reviewed for standards compliance, scientific correctness, and usability by other planetary scientists. All PSA products use the PDS standards. PSA products are available freely to the community, sometimes after a proprietary period, and can be downloaded from this portal

The data can be obtained from the PSA through various interfaces:
- FTP interface
- on line search interface
- scriptable machine interface
- IPDA interoperability data access interface

The PSA team is responsible for the development, implementation and operation of the archive, driven by the scientific needs of the community and the missions. The PSA is a single node for all ESA’s planetary missions that gather scientific and technical support from various resources (e.g., Project Scientists, Archive Engineers, Science Ground Segments, Archive Scientists, etc.). As such, the PSA is mostly located at the European Space Astronomy Centre (ESAC) in Spain.

The PSA team works closely with the missions (in particular with their Project Scientist and the Science Ground Segments) to advise and provide support in all aspects related to archiving, and to coordinate the integration of the mission archive into the PSA. Each mission is assigned an Archive Scientist who is responsible for defining archive formats, interface documents and the mission’s science data management plan. Archive scientists are the main interface with the mission instrument teams for all archiving aspects, while archive engineers ensure that all archiving aspects are implemented at the ESAC Science Data Centre (ESDC) level.
