Messina Chasma is the largest canyon on the surface of the Uranian moon Titania

. The 1492 km long chasma is made of two normal faults running NW–SE, which bound a down-dropped crustal block forming a structure called graben
. The canyon cuts impact craters, which probably means that it was formed at a relatively late stage of the moon's evolution, when the interior of Titania expanded and its ice crust
cracked as a result. Messina Chasma has only few crater superimposed on it, which also implies it is relatively young structure. The chasma was first imaged by the Voyager 2
spacecraft in January 1986.
