  • 2/20/18 - Visit the PDS Booth at LPSC!
    The PDS booth in the LPSC exhibit area will be staffed with PDS personnel who can provide you with guidance or assistance on a wide range of PDS topics. Training opportunities will also be available! Sign up to request help with specific topics here:, or drop in for an informal chat with PDS staff.

  • 1/26/18 - The International Earth Rotation Service (IERS) has announced there will not be a new leapsecond added on June 30, 2018. As a consequnece, the currently offered SPICE leapseconds kernels (LSK), naif0012.tls for Linux and Mac, and naif0012.tls.pc for Windows, will remain in effect until at least the end of December, 2018.

  • 01/09/18 - The set of on-line SPICE tutorials has been upated.

  • 01/09/18 - NAIF offers a SPICE newsletter.

  • 11/03/17 - All of the on-line tutorials, the programming lessons, and the self-training packages (class tutorials and programming lessons) have been updated.

  • 8/9/17 - N0066 Toolkit DSK Bug. A bug, not very likely to be encountered, exists in the DSK subsystem of the N0066 Toolkits. Read the announcement (PDF) for details.

  • 6/1/17 - Due to equipment failure, NAIF will not be able to provide future Toolkits (version N67 and beyond) for the Sun/Intel Solaris environments.

  • 5/11/17 - Regarding CubeSat and Similar Missions
    Directions from NASA HQ stipulate that any cubesat or similar mission that would want support from the NAIF Group in deploying and operating SPICE production capabilities, or in providing consultation to SPICE operators or scientists using SPICE, must be paid for by the project, just as is done for larger projects. Projects are free to implement and operate SPICE on their own without help from NAIF. In this case you'll need people experienced in producing and validating SPICE kernels, and in monitoring the SPICE production pipeline for SPK, CK and SCLK kernels. Selecting an Ancillary Data System (PDF) provides some commentary that could be useful.

  • 4/10/17 - NAIF announces release of the Version N66 Toolkits, with the first formal inclusion of the tesselated plate portion of the Digital Shape Kernel (DSK) as the principle addition. See the above-mentioned newsletter for more detail.

  • 01/27/17 - Due to new NASA IT security requirements, on January 27, 2017 the NAIF HTTP server was reconfigured to redirect all http: requests to https:. While this change is transparent for access via most Web browsers, it might have affected access via curl and wget. Transfers initiated with recent versions of wget and of curl (with the -L option) should work but those done with older versions of both tools might fail. We recommend that all users who automatically copy kernels and toolkit packages from the NAIF server via HTTP using wget, curl, and similar utilities verify that they still do it successfully with this new server configuration.
