    Instrument Characteristics
    ISS consisted of a narrow angle slow scan video camera (1500 mm narrow-angle f/8.5 lens) with its field-of-view nested in the view of a lower resolution (200 mm wide-angle with a f/3 lens) wide-angle camera. Each camera had an 8 aperture filter wheel mounted in front of the camera that was stepped by sequences built into the command file sent up to the onboard computer. Limitations of computer memory and the fact that the videos were red-blind produced a data set with considerable dynamical content but limited vertical information (no strong CH4 filter images).

    ISS Science Objectives

    • Observe and characterize the circulation of the planetary atmosphere, provide limits on atmospheric composition, and determine the wind velocities in the regions observed.
    • Map the radial and azimuthal distribution of material in the ring plane; search for new rings.
    • Obtain global multi-spectral coverage of all satellites; establish rotation rates and spin axis orientations, study the surface morphology of Triton at spatial resolutions less than 2 km; search for undiscovered satellites.
    • Provide support images to assist other onboard investigations in their data reduction
