Many
circular depressions -- probably impact craters -- are visible in this clear-filter
image returned by the Voyager narrow-angle camera. Other bright spots are
distinguished by radiating rays and are probably halo craters that mark
relatively more recent impacts. |

Even
more interesting are linear troughs (right) that are probably fault canyons.
The troughs break the crust in two directions, an indication of some tectonic
extension of Titania's crust. These features indicate that this icy satellite
has a dynamic, active interior. Titania is about 1,600 km in diameter; the
resolution of this image is about 9 km. |
