The Planetary Data System (PDS) is an archive of data products from NASA planetary missions, which is sponsored by NASA's Science Mission Directorate. We actively manage the archive to maximize its usefulness, and it has become a basic resource for scientists around the world.

The Navigation and Ancillary Information Facility (NAIF), acting under the directions of NASA's Planetary Science Division, has built an information system named 'SPICE' to assist NASA scientists in planning and interpreting scientific observations from space-borne instruments, and to assist NASA engineers involved in modeling, planning andexecuting activities needed to conduct planetary exploration missions The use of SPICE extends from mission concept development through the post-mission data analysis phase,including help with correlation of individual instrument data sets with those from other instruments on the same or on other spacecraft.
