What is the Planetary Data Ecosystem?

NASA defined the Planetary Data Ecosystem (PDE) as the ad hoc connected framework of activities and products that are built upon and support the data collected by planetary space missions and research programs, which primarily are NASA funded.

The PDE IRB further elaborated on this concept by enumerating the types of information in the PDE and the communities involved.

  • Data returned from space missions and ground-based facilities, including observational data, telemetry and other engineering data, samples, and mission planning documents
  • Data generated by research and analysis projects, including observational data analysis, theoretical research, laboratory results, and Earth analog site field tests
  • Data generated by citizen scientists, including participants in observation campaigns, contributors to collaborative citizen-science services, and space enthusiasts
  • Standards for planetary science data and metadata
  • Software including data processing pipelines, analysis tools, search and browse tools, display tools, and simulation tools
  • Publications, including articles, books, conference abstracts, reports, posters, and presentations
  • Education and communication products, including value-added products from missions and facilities (websites, captioned photos, etc.), educational materials, recordings of outreach events, products generated for the media, and unpublished photo and video documentary material gathered for public engagement purposes.

The communities include:

  • Personnel from NASA and other space agencies (themselves containing many different stakeholder groups)
  • Mission and ground-based facility personnel
  • Science researchers, technology innovators, software developers, media professionals, historians, artists, and others who use planetary data in a professional capacity
  • Amateurs, enthusiasts, and hobbyists
  • Educators, students at all age levels, and parents of students, in both formal and informal education environments.
