Hi all,

These grooves are not unique to Vesta and have been found on a number of
other bodies with numerous formation theories. In fact here is one paper
dedicated to grooves on asteroids and moons:

Cheers,

Jeff

Oh, what the heck, I'll throw in my thoughts too. Could the Vesta
grooves be faulting combined with later slumping (as seen many lunar
craters) caused by the force of impact?
