The '''Planetary Data System''' ('''PDS''') is a distributed data system that [[NASA]] uses to archive data collected by [[Solar System]] missions.

The '''Planetary Data System''' ('''PDS''') is a distributed data system that [[NASA]] uses to archive data collected by [[Solar System]] orbital, landed and robotic missions and ground-based support data associated with those missions. The PDS is managed by NASA Headquarters' Planetary Sciences Division. The PDS is an active archive that makes available well documented, peer reviewed planetary data to the research community.<ref>{{Cite web|title = PDS: PDS Charter|url = https://pds.nasa.gov/about/pds_charter_12102015.pdf|website = pds.nasa.gov|accessdate = 2017-08-16}}</ref> The archive and data within are held to high quality standards established by the PDS. The PDS is divided into a number of science discipline "nodes" which are individually curated by planetary scientists. The Principal Investigators of the science discipline nodes, along with the leaders of the Technical Support Nodes, the Project Manager, and Deputy Project Manager form the PDS Management Council (MC). The MC serves as the Technical Policy Board of the PDS, and provides findings for NASA with respect to planetary science data management, ensures coordination among the Nodes, guarantees responsiveness to customer needs, and monitors the appropriate uses of evolving information technologies that may make PDS tasks both more efficient and more cost effective.<ref>{{Cite web|title = PDS: PDS Requirements|url = https://pds.nasa.gov/roadmap/pds_level123_requirements_20170420.pdf|website = pds.nasa.gov|accessdate = 2017-08-16}}</ref> The Solar System Exploration Data Services Office at the [[Goddard Space Flight Center]] handles PDS Project Management.<ref>{{Cite web|title = PDS: PDS Organization|url = https://pds.nasa.gov/about/organization.shtml|website = pds.nasa.gov|accessdate = 2015-10-16}}</ref>

==Nodes==

The PDS is composed of 8 nodes, 6 science discipline nodes<ref>{{Cite web|title = NASA Issues New Awards for Planetary Data System|url = http://www.prnewswire.com/news-releases/nasa-issues-new-awards-for-planetary-data-system-300157414.html|website = www.prnewswire.com|accessdate = 2015-10-16}}</ref> and 2 support nodes. In addition, there are several subnodes and data nodes whose exact status tends to change over time.

===Science discipline nodes===

*Atmospheres Node - handles non-imaging atmospheric data ([[New Mexico State University]])

*Geosciences Atmospheres Node - handles datanon-imaging ofatmospheric the surfaces and interiors of terrestrial planetary bodiesdata ([[WashingtonNew Mexico State University]])

* Geosciences Node - handles data of the surfaces and interiors of terrestrial planetary bodies ([[Washington University]])
* Cartography and Imaging Science Node - archives many of the larger planetary image data collections ([[Astrogeology Research Program]] of the [[United States Geological Survey]], and [[Jet Propulsion Laboratory]])

* Planetary Plasma Interaction (PPI) Node - handles data consisting of the interaction between the solar wind and planetary winds with planetary magnetospheres, ionospheres and surfaces ([[University of California, Los Angeles]])

* Ring-Moon Systems Node - handles planetary ring system data ([[SETI Institute]])

* Small Bodies Node (SBN) - handles asteroid, comet and planetary dust data ([[University of Maryland, College Park]])

** Comet Subnode ([[University of Maryland, College Park]])

** Asteroid/Interplanetary Dust Subnode ([[Planetary Science Institute]])

===Support nodes===

*Engineering Node - provides systems engineering support to the PDS ([[Jet Propulsion Laboratory]])

* Engineering Node - provides systems engineering support to the PDS ([[Jet Propulsion Laboratory]])
* Navigation and Ancillary Information Facility (NAIF) Node - maintains the [[Space Planet Instrument C-matrix Events|SPICE]] information system ([[Jet Propulsion Laboratory]])

==Organizational Structure==

The PDS is divided into a number of science discipline "nodes" which are individually curated by planetary scientists.

The PDS Management Council serves as the Technical Policy Board of the PDS, and provides findings for NASA with respect to planetary science data management, ensures coordination among the nodes, guarantees responsiveness to customer needs, and monitors the appropriate uses of evolving information technologies that may make PDS tasks both more efficient and more cost effective.<ref>{{Cite web|title = PDS: PDS Requirements|url = https://pds.nasa.gov/roadmap/pds_level123_requirements_20170420.pdf|website = pds.nasa.gov|accessdate = 2017-08-16}}</ref> It is formed by the [[Principal investigator|principal investigators]] of the science discipline nodes, along with the leaders of the Technical Support Nodes, the Project Manager, and Deputy Project Manager.

==Roadmap 2017-2026==

NASA and the PDS recently engaged in development of a Roadmap for the period 2017 to 2026. The purpose of the roadmap effort was to outline a strategy for moving forward in planetary data archiving under the auspices of a rapidly growing data volume (nearly 1 petabyte at present), new computing capabilities, tools, and facilities, and a growing community of planetary science investigators.<ref>{{Cite web|title = PDS: PDS Roadmap 2017 to 2026|url = https://pds.nasa.gov/roadmap/PlanetaryDataSystemRMS17-26_20jun17.pdf|website = pds.nasa.gov|accessdate = 2017-08-16}}</ref>
