Acheron Catena

Image of the Day explores the nomenclature of Mars. Acheron Catera = Catera: chain of craters. Acheron: river of woe. Acheron is one of the nine rivers separating Hades from the land of the living. It is across Acheron that Charon ferries the dead. Cerberus guards this river. If a person is not buried correctly, or does not have the fare to pay Charon, his/her soul is doomed to wander the banks of Acheron forever.
Acheron Catena is a line of craters found on the flanks of Alba Patera - a very old volcano. The majority of the craters appear to have formed by collapse. Nomenclature Fact of the Day: Earth's Moon is the only body in the solar system (besides Earth) that uses the descriptor Oceanus.
