The stalwart Cassini orbiter continues to explore Saturn and its rings and moons. On 25 August 2011 the orbiter flew within 25,000 km of Hyperion, an oddly shaped moon just 270 km across whose tumbling orbit has obscured details of its surface.

The new images collected will be used to map the moon’s terrain and relate the brightness and colours seen as the moon rotates to surface composition and texture. This is an unprocessed image of Hyperion showing its irregular cratered surface.

This image is published in the October 2011 issue of Astronomy & Geophysics.
