SPICE data produced by NAIF are offered through
this web site. This includes formally archived data sets, operations
data from active missions, generic kernels, and some pre-SPICE-era data that have been "restored" into SPICE formats.
SPICE data produced by other NASA centers and archived with the NAIF node of the
PDS are also available here.
Mission operations SPICE data produced by ESA (ESAC) for Mars Express (MEX),
Venus Express (VEX) and Rosetta are mirrored here. Once
archival SPICE data increments are produced for these missions, those data will be
available here in addition to being available from the primary location in
ESA's Planetary Science Archive (PSA).
SPICE data produced by other foreign space agencies may or may not be available from those agencies. Check our Useful Links page for further information.
NAIF has some additional SPICE data that are undergoing restoration—pieces
of which may be available. Galileo and Voyager are examples.
