• The Moon, as Seen by Cassini Spacecraft

This brief 3-frame movie was made from 3 narrow angle ISS images. The purpose of this particular set of images was to calibrate the spectral response of the narrow angle camera and to test its on-chip summing mode in flight. From left to right, they show the Moon in the green, blue and ultraviolet regions of the spectrum in 40 msec, 60 msec, and 80 msec exposures, respectively. All three images have been scaled so that the brightness of Crisium basin, the dark circular region in the upper right, is the same in each image. The spatial scale in the blue and ultraviolet images is 2.3 km/pixel. The original scale in the green image (which was captured on the CCD in the usual manner and then reduced in size by 2x2 pixel summing within the camera system) was 4.6 km/pixels. It has been enlarged for display to the same scale as the other two through bicubic interpolation.
