Southern Solitude
image by Yuri Goryachko, Mikhail Abgarian, Konstantin Morozov, Minsk, Belarus.
What a variety of landforms in this view looking across the Australe sea. The mare itself is like a collection of lakes
rather than a broad sea. There is a basin under it all but it must have been an early one that healed isostatically -
the warmth of the early crust allowed the fractures to heal and the mountainous rim to subside. The lava fill is probably only a kilometer or so thick, not enough to cause subsidence to produce circumferential rilles. Looking across
Australe is the crater Jenner at 96° E longitude. At the far left is Humboldt, perhaps an outlier perhaps based on its
lava patches, but Humboldt's lavas are darker and perhaps younger than those of Australe. At the center of the scene
are two of the smallest fresh craters with the longest rays. With this lighting and excellent processing the two rayed
craters are finally visible. Finally, at the right is what looks like a railroad bending into the distance. This is the Rheita
Valley, a chain of secondary craters formed by debris ejected from the Nectaris Basin. This is a great corner of the
Moon to view with understanding. Visit the entire marvelous Minsk mosaic that this is only a fragment from.
