Making an Impact

Light plains (outlined in yellow) are smooth, gently rolling deposits located in the lunar highlands. Their resemblance to mare ponds (outlined in blue) originally led to the idea that they were volcanic in origin. Image width is...

Chappy Oblique

Spectacular oblique view (65° slew angle) of a 1400 m diameter crater that formed on the rim of Chaplygin crater. Delicate lacy fingers of ejecta highlight the hummocky and steep topography around this young crater. The very brightest...

Fresh, But Not So Clean

LROC NAC image M131515002R showing two similarly sized craters, ~500 m in diameter, but one is littered with boulders and the other is not.  This boulder discrepency is most likely due to age differences between the two craters....
