Overview
NSSDCA supports the space science research community, the education enterprise, and the general public. Further information on NSSDCA's designated community is available.
NSSDCA also maintains a large collection of film products. "Space science" here encompasses astronomy and astrophysics, solar and space plasma physics, and lunar and planetary science.
NSSDCA mainly distributes digital data. Effective 01 January 2007, requests for photos and non-digital data are handled on a case-by-case basis involving the head of NSSDCA. When appropriate, duplication can be initiated if all costs are recovered, including potential digitization of material and posting on FTP.
NASA Archives
NASA provides extensive resources for both long-term archiving of space science data through its Permanent Archive (NSSDCA) and more immediate short-term or real-time data access through active archives.
- Data ingest
- Archival storage
- Data management
- Preservation planning
- Cross-system access
- Data ingest
- Added-value services
- User access
- Data management
- Cross-system access
As the permanent archive, NSSDCA communicates with the various active archives. Active archives in turn communicate with NSSDCA and the scientists, educators, and others who are end users of the data. In addition, numerous project, mission, and investigator web sites provide access to current data, some of which are not yet available through an active archive.
Active Archives Within NASA's Science Mission Directorate
The Planetary Data System
PDS — NASA's primary repository for planetary science data
Space Physics Data Facility
SPDF — Heliospheric and magnetospheric data access and services
Astrophysics Data Centers
Consortium of NASA astrophysics archive and service centers
In addition to the principal NASA archives and various project, mission, and PI data sources, new information technologies are enabling higher-level access across heterogeneous data sources and systems. These new data venues are called virtual observatories or data grids:
Virtual Solar Observatory
Serves the solar physics community
Virtual Astronomical Observatory
Serves the astrophysics community
SPASE Initiatives
Space Physics Archive Search and Extract (SPASE) data model and dictionary activities currently include sample SPASE descriptions. Data for these collections may be offline but can be acquired through the CRUSO office listed below.

Further questions about data availability and ordering can be directed to the NSSDCA Coordinated Request and User Support Office (CRUSO). CRUSO staff are available to help researchers, educators, and the public access the data they need.
