Announcements

(Most recent at top)

  • 11-19-14 - The IERS has announced a new leap second will NOT be added at midnight on 31 December 2014. Thus the current SPICE leapseconds kernels (LSK) available from the NAIF server at the usual location, http://naif.jpl.nasa.gov/pub/naif/generic_kernels/lsk/, will remain effective. Separate versions for Unix/Linux/Mac (naif0010.tls) and for PCs running Windows (naif0010.tls.pc) are available.

  • 10-31-14 - NAIF put on a SPICE training class in Columbia, Maryland on October 21 - 23. Notes from that class in PDF format, including student feedback, are available.

  • 7-23-14 - The SPICE Toolkits have been changed to the new N65 versions. These are fully backwards compatible with previous versions, so we recommend all SPICE users to upgrade. Read the "whats.new" for your programming language and computing environment for details about new and revised capabilities and bug fixes.

  • 4-17-14 - A new, generic planetary constants kernel (PCK) containing Gm values for the planets, their major satellites, and the planet-satellite systems has been placed on the NAIF server here:

  • 1/2/14 - A new link has been added to the NAIF website: "Self training." This provides access to the reduced set of SPICE tutorials (generally smaller versions, and fewer of them) and the SPICE programming lessons used in the SPICE training classes taught on occasion near JPL. Use this link to conduct your own beginner's SPICE training class.

  • 10/31/13 - NAIF has announced the release of Version 1.0.0 of WebGeocalc (PDF). WGC provides a graphical user interface to many of the observation geometry capabilities available within the SPICE system. A WGC user need have only a computer with a standard browser and an Internet connection — all of the computations are done on the NAIF server, which has access to all of the SPICE data stored thereon.

  • 7/1/10 - An alpha-test version of the SPICE Digital Shape Kernel (DSK) subsystem is available. This release makes use of the latest and final underlying Digital Shape Kernel file format—it will not change from now on. Contact NAIF for details on how to access one of these toolkits.
