SPDF

Space Physics Data Facility (SPDF) is the NASA active and permanent archive for non-solar heliophysics data (solar data at SDAC), per the NASA Heliophysics Science Data Management Policy. SPDF is a project of the Heliophysics Science Division (HSD) at NASA's Goddard Space Flight Center. SPDF also provides multi-project, cross-disciplinary access to data to enable correlative and collaborative research across discipline and mission boundaries with present and past missions. SPDF maintains 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
NOTICE: December 3, 2021: ALL SPDF systems/services (CDAWeb, SSCWeb, OMNIWeb, CDF, etc.) will be unavailable from 8pm - 12:00am EST Friday December 3rd. Please plan your use of the systems/services accordingly.

October 2021: The Parker Solar Probe (PSP) data have been extended to June 2021 (for FIELDS) and July 2021 (for SWEAP and ISOIS), which covers all of Orbit 8, including Encounter 8 with perihelion in April 2021. The FIELDS and SWEAP data have updated quality flags. Because EPI-Lo species identification tables were updated on 14 June 2021, the ion composition (IC) files in this release have added the variables related to N and Ne count rates, although they are not populated yet.

September 30 2021: The SPDF websites use Let's Encrypt for our web site HTTPS certification. One of the Let's Encrypt root certificates (DST Root CA X3) expired on Sept. 30, 2021. You may find that some web tools report that our SSL certificates cannot be verified. If so, please update those tools to support the latest root certificates, and to use OpenSSL 1.1.0 or later. This includes updating the root certificates used by curl and wget, and IDL (IDL 8.7.1 and 8.8's ca-bundle.crt work). Compatible software package versions are listed at https://letsencrypt.org/docs/certificate-compatibility/.

The MMS Level 2 data products are available via SPDF HTTPS and all data sets are available in CDAWeb. The range of publicly available MMS data will continue to be updated weekly.
