Bruce commented (some time ago) on a suggestion that the grooves on Phobos may be caused by ejecta from its big crater stickney rather than as surface expressions of deep fractures.

This reference:

http://sci.esa.int/science-e/www/object/do...fobjectid=36756

suggests that Mars basin ejecta did the deed instead. Personally (IM not-so-H O) I think Murray does a better job than Wilson and Head of making the case for ejecta. I prefer a fracture explanation myself, and I have suggested previously that the fractures responsible may be more like terrestrial jointing, produced by relaxation after excavation from a parent body. At any rate, fractures or ejecta, the tie to Stickney is very dubious.

This dispute is why I have a particular interest in scrutinizing small bodies for evidence of grooves. It's nice to see a few on Pandora.
