Welcome to SPICE: NASA's Solar System Exploration
Ancillary Information System
|
The Navigation and Ancillary Information Facility (NAIF) offers an information system named
"SPICE" to assist scientists in planning and interpreting scientific observations from space-borne
instruments. SPICE is also widely used in engineering tasks needing access to space geometry.
SPICE is focused on solar system geometry, time, and related information.
The SPICE system includes a large suite of software, mostly in the form of subroutines, that
customers incorporate in their own application programs to read SPICE files and to compute derived
observation geometry, such as altitude, lattitude/longitude, and lighting angles.
SPICE data and software may be used within many popular computing environments.
The software is offered in FORTRAN, C, IDL® and MATLAB®.
NAIF is the "Navigation Node" of NASA's Planetary Data System.
