Hidden Ancient History
image by Jocelyn Sérot, France
Is this a corner of the Moon you overlook? Have you specifically observed any of these craters? I thought not. The north eastern limb is an area lacking in remarkable craters, has only the smallest patch of mare lava, and generally looks tired. There are no detected basins right here to provide interesting rilles and wrinkle ridges. Its not as highly cratered as the farside so at some point the really old craters were erased. About the only way to erase things is a large impact, so perhaps Spei does mark the location of an ancient |basin, gone except for crustal weaknesses that later allowed a little magma to reach the surface. This area was apparently much more interesting 3-4 billion years ago. We came too late for the best view.

The rotating globe shows locations of folks who visit LPOD. The most recent visits include location names - so you can see who else is on when you visit. For example, if you see "Wheeling/ West Virginia" I am probably editing an LPOD. After a few minutes just a small red dot appears.
