Operational Flight Project Kernels

SPICE kernels for currently active missions where NAIF produces the kernels or otherwise has access to them may be obtained directly from the NAIF server using the links below. Included under this category are kernels from past missions that have not yet been archived in the PDS. Mars Missions Outer Planet Missions Comet and Asteroid Missions Venus Missions Lunar Missions Mercury Missions Earth-Sun Connection Mission Astrophysics Missions 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. (Kernels for a few ESA-sponsored missions are mirrored at NAIF by agreement between ESA and NASA, for the convenience of U.S. participating scientists.)
