I suspect there is a lot of loose dust. Another possibility is lines of impacts from groups of small meteorites gravitationaly bound together.

A photo of the Vesta asteroid shows the same type of grooves.

I'm sure they know if there is or not. If I had the time now, I'd look into it. Makes sense that there would be, given all of the impacts. Our moon is covered in regolith as a result of countless impacts, mostly from billions of years ago.
