Can you recognize the main features of this slice of a sliver? In Maurice's image of a 2 day old Moon
many features are identifiable that are often poorly seen at this thin phase. The two flat spots near center
are Mare Smythii (right) and Mare Marginis (left), with Neper in between. This oblique view also shows
how these two lava-filled impact basins actually are convex instead of concave, because they are so
big that the curvature of the Moon controls their shape. And it is the tight curvature of a small world that
makes the walls of even a smaller feature like Neper be invisible for an astronaut standing on the central
peak.
