-- CK Basic
-- This example creates a time frame based on the information provided by a single SPICE
-- kernel file. The created scene graph node will only be valid whenever the provided
-- kernel contains information about about the reference frame "-98000", which is the
-- interial orientation frame for the New Horizons spacecraft.

-- We need a SPICE kernel to work with in this example
