Do they have any idea what that chain of craters is? Fricking weird.
I've heard the theory that the 'stripes' on Phobos (including the string of craters) are ejecta from earlier impacts. When the moonlet hits debris, the material that's ejected from the new crater spreads out radially, but falls back to the moon, forming strings of craters. Or something like that.
