For the first time ever, a spacecraft approached closely enough to the asteroid Lutetia to see its surface clearly. Craters dot the surface, as well as grooves. Note the elongated crater near the bottom (left of center); was that from a nearly horizontal impact? It's curious that it points almost directly to the crater to the left. That may just be coincidence; the surface is so cratered that some are bound to be in patterns just randomly.
