Caption NASA:"The sponge-like Surface of Saturn's moon Hyperion is highlighted in this Cassini portrait, captured during the Spacecraft's Sept. 16, 2011, Fly-By. Hyperion (which is about 168 miles, or approx. 270 Km across) has an irregular shape, and it tumbles through its orbit: that is, it does not spin at a constant rate or in a constant orientation. (A standard reference latitude-longitude system has not yet been devised for this moon.)
Images such as this one extend previous coverage and allow a better inventory of the surface features, the satellite's shape and changes in its spin.
The image was taken in Visible Blue Light with the Cassini Spacecraft narrow-angle camera. The view was obtained at a distance of approx. 55.000 miles (such as about 88.000 Km) from Hyperion and at a Sun-Hyperion-Spacecraft, or Phase, Angle of 37°.
Image scale is roughly 1720 feet (524 meters) per pixel".
