IDL Used to Visualize and Analyze Saturn's Rings Customer Challenge Scientists at the Laboratory for Atmospheric and Space Physics (LASP) located at the University of Colorado, Boulder needed a method to analyze and visualize information coming from The Ultraviolet Imaging Spectrograph installed on board Cassini. Solution Achieved Cassini is a spacecraft that entered Saturn’s orbit on July 1, 1997 and began sending information and images of Saturns atmospheres, rings, and surfaces to Earth shortly after. “We use IDL to determine where the camera is pointing and where we need to look for information in the rings,” said Joshua Colwell, a scientist on the Cassini team with LASP. “We also use IDL to model the ring plane, map the sensor data onto the ring model and then generate an accurate ima
