The IAU has just approved new names for 35 craters, dorsa, fossae, and sulci on the surface of Enceladus, based upon Cassini's high-resolution mapping of the little moon. What are dorsa, fossae, and sulci, you might ask?
A dorsum (plural: dorsa) is a ridge.
A fossa (plural: fossae) is a long, narrow depression.
A sulcus (plural: sulci) is a set of subparallel furrows and ridges.
Among the newly named features are Enceladus "tiger stripes," the south polar water-vapor-spewing grooves. Here's a map with the new names:
Jason Perry helpfully posted a map put together by Steve Albers with all of Enceladus' feature names; you can download that here (it's 6 MB).
I think it's interesting that the four large tiger stripes are named Alexandria, Cairo, Baghdad, and Damascus...it's really helpful mnemonically for these four prominent features to have names starting with A, B, C, and D—but they're not in that order! It's A, C, B, D instead. That's odd.
