This is a multispectral image cube of Io from NASA's Voyager 2 images, simple cylindrical projection.

New multispectral image cube of Io from Voyager 2 images, simple cylindrical projection. Top: Natural color, Middle: enhanced color, Bottom: color-ratio composite. Improvements compared to old global mosaics of McEwen (1988) allow us to recognize new spectral units and relations and will facilitate comparisons to HST and Galileo observations.
