The SPDF is a project of the Heliophysics Science Division (HSD) at NASA's Goddard Space Flight Center. SPDF consists of web-based services for survey and high resolution data and trajectories. The Facility supports data from most NASA Heliophysics missions to promote correlative and collaborative research across discipline and mission boundaries. Read More here.

News & Announcements
August 1, 2019: As part of Federal policy to encrypt all network connections, FTP access to the SPDF and CDAWeb data archive was changed to TLS-encrypted FTPS on July 31, 2019. Browsers and traditional command line FTP will NO LONGER CONNNECT with FTP, but HTTPS access remains. For more information and alternatives, see our FTPS Readme.
