Rilles Almost All Around
image by " rel="nofollow Damian Peach
No, the vertical line crossing the top half of Arzachel's floor is not a mosaic seam boundary. It is the best view so far of a straight rille that was detected " rel="nofollow previously. With Damian's new image, there is a suggestion that the radial rille is tenuously crossed by a crater chain/rille extending from the bird's foot end of the Arzachel Rille. Opposite " rel="nofollow lighting supports this interpretation, but it is not certain if the connection is real. Damian's impressive image also confirms faint, apparently degraded rille segments cutting a rubbly area of the southern part of the floor. Thus, rilles have been imaged on three sides of Arzachel's floor; it will be interesting when modern orbiter images become available - or terrestrial imagers make the next quantum improvement - if rilles are found on the western side. If a crater floor moved up or down, I'd expect all parts to be fractured.
