Another closeup of Lutetia's surface provided by Rosetta. In this shot, you can again see a variety of craters peppering the asteroid, as well as some grooves that follow the landscape. Those curves give a relative age for the grooves: they must have formed after the impact crater on the right, which distorted the landscape. Also, had they formed before, the impact would have eradicated them. Images like this can give scientists a vast amount of insight into the history of the asteroid.
