Still distant from Titan, Cassini's VIMS spectrometer recorded the first images of the exotic, cloud-veiled moon's surface in visible and near infrared wavelengths on 2 July 2004. While taken at low resolution, surface textures are already visible, shown in varying brightness and false colour. In the southern hemisphere of the moon, a large methane cloud can be seen and, during the observations, could be seen to change. Yellowish areas are characterized by a high hydrocarbon content, including ethane and methane, while green indicates a higher content of ices. Credit: NASA/JPL/University of Arizona/USGS.
