I Walk the Line
This view shows a remarkable line of secondary craters, formed by a set of similar-sized blocks thrown out by the impact that formed an unnamed 150-km diameter crater, whose rim is just to the southeast of the lower right end of the crater chain. The individual secondary craters in the chain are each about 4 to 6 km wide. The uniformity of the size of these secondaries and their arrangement in a line nearly radial to the center of the primary crater hint at the complex physics involved in the impact process.
