Kernels for currently active missions where NAIF produces the kernels or otherwise has access to them, kernels from some pre-SPICE era missions, and miscellaneous other mission kernels
may be obtained from the NAIF server
using the links below. Included under this category are some kernels from past missions that have not yet been archived in the PDS.
Please note that kernels produced by agencies other than JPL are usually available only at those agencies, and may not be
available to other than the flight project's team members. (By
agreement between ESA and NASA, kernels for a few ESA-sponsored missions are mirrored at NAIF for the convenience of U.S. participating scientists.)
