Today's Featured Image looks like a parched Arizona mudflat after a monsoon downpour. Not quite! You are looking at the broken surface of an impact melt pond inside Giordano Bruno crater. A surface crust fragmented into angular blocks up to about 40 m in width as still molten rock was drained from beneath a hardening crust. The small clusters of relatively bright rock fragments are likely boulders that rolled down from the nearby steep walls.
