Access to the Space Physics Data Facility (SPDF) public archive by directory, with additional access methods(including web services).
The Satellite Situation Center (SSCWeb) provides orbits from multiple spacecraft in listings and plots, and interactively with the 4D orbit display. It also enables complex queries based on geophysical regions, magnetic field tracing, and ground stations.

NASA's Space Physics Data Facility (SPDF)
Heliophysics studies the nature and dynamic interactions of the Sun, the heliosphere, and the plasma environments of the planets and interstellar space. The Heliophysics Digital Resource Library (HDRL) archives and serves the heliophysics data, as a project in the Heliophysics Science Division (HSD) at NASA's Goddard Space Flight Center. Space Physics Data Facility (SPDF) is the active and permanent archive for the space physics data, while solar data is archived at Solar Data Analysis Center (SDAC), as components of the HDRL, per NASA’s Heliophysics Science Data Management Policy.
SPDF provides multi-project, cross-disciplinary access to data to enable correlative and collaborative research across discipline and mission boundaries with present and past missions. Many datasets from current missions are updated regularly (even daily), including reprocessed data for older time periods, and SPDF only preserves the latest version. SPDF maintains the CDAWeb data explorer and browsing system, the SSCweb database of spacecraft orbits, the OMNIWeb cross-normalized database, and the Common Data Format (CDF) self-describing science data format and associated software.
News & Announcements
2023 November: Try out our new prototype browser-based 4D Orbit Viewer to display the SSC spacecraft orbits in an interactive 3-D animation tool.
2023 November: The SPDF website has been completely revised to apply the US Web Design System (USWDS) to provide consistent usability, accessibility, editorial style, and a common look-and-feel across the US Government. We tried to preserve existing URLs where possible, and added an acronym/glossary list and a large list of heliophysics resources. Please contact us with any issues, additions, or suggestions.
2023 November: The PSP data have been extended to August 2023 (availability depending on data sets), covering Encounter 16 and some of Orbit 16. Please check CDAWeb for the data and PSP inventory plot and annual inventory plots for details.

Process and requirements for submitting new data to HDRL archives (SPDF and SDAC)
The OMNI dataset provides cross-normalized solar wind field and plasma data mapped to the nose of the bow shock, geomagnetic and solar activity indices, and energetic particle flux data. COHOweb provides access to magnetic field, plasma, energetic particle, and spacecraft position (also at HelioWeb) data from many deep-space spacecraft (Voyager, Ulysses, STEREO, Pioneer, Helios, etc.).
CDF scientific file format stores multi-dimensional data in a platform-independent self-describing format, with associated software libraries, including SKTeditor for defining the structure and metadata for new datasets.
