The troughs of Raditladi are the focus of this high-resolution view inside the peak-ring basin. The troughs, which are largely concentric to the basin, formed through extensional stresses that caused portions of the floor to pull apart. Such extensional features are similar to those observed within Caloris. Some of the small, bright craters that dot Raditladi's floor may be secondaries from Fonteyn crater approximately 900 km away, whose rays appear to cross the basin.
This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.
