• The Moon, as Seen by Cassini Spacecraft

This brief movie illustrates the passage of the Moon through the ISS wide angle camera field of view as the Cassini spacecraft flew by the Moon, on the way to its closest approach with Earth. From beginning to end of the sequence, 25 wide angle images (with a spatial image scale of ~ 23 km/pixel) were taken over the course of seven and a half minutes through a series of narrow and broadband spectral filters and polarizers, ranging from the violet to the near-infrared regions of the spectrum, for the purposes of calibrating the spectral response of the wide angle camera. The exposure times range from 5 msec to 1.5 seconds. Two of the exposures were smeared and have been discarded and replaced with nearby images to make a smooth movie sequence. All images were scaled so that the brightness of Crisium basin, the dark circular region in the upper right, is approximately the same in every image.
