A more or less true-color image of Titania, taken by Voyager 2 in 1986. This image and the one below show an ancient heavily cratered surface on the right, and extensive fault systems on the left. At the time these images were taken the South pole of Uranus and its moons were facing the Sun so South is on the right and North on the left.
(NASA, Voyager 2, apod000930)
Another image of Titania, with brightness and contrast adjusted to emphasize small detail. The large impact crater (Gertrude) at the bottom is about 180 miles across. A 60-mile wide fault valley, or chasma, cuts into a crater (Ursula) at the bottom. The prominent fault valley systems near the center extend for nearly 1000 miles, or about a third the circumference of Titania (and may of course extend even further into the unlit and therefore non-imaged portion of the satellite).
