New generic PCK
----------------------
NAIF has placed an update of the SPICE “generic” PCK file on the NAIF server. This file contains orientation and size/shape data for the planets, natural satellites, Sun, and selected comets and asteroids. With a few exceptions, documented in the file, the data are taken from the “Report of the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements: 2006." The new file is named pck00009.tpc. The file may be accessed from the NAIF server ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/pck/ or from the NAIF web site by following the links “Data,” “Generic Kernels,” “generic_kernels,” and “pck.”
The new PCK also may be accessed using anonymous ftp to the location shown above.
We anticipate the IAU will publish its next “Report” fairly soon; NAIF will create a new generic PCK based on it soon thereafter.
Updated Tutorials
-----------------------
Many of the SPICE tutorials have been updated. Changes were made to add current information, improve clarity (we hope), or correct errors. The updated tutorials are dated March 2010.
