Anticipated electrical environment within permanently shadowed lunar craters

Shadowed locations near the lunar poles are almost certainly electrically complex regions. At these locations near the terminator, the local solar wind flows nearly tangential to the surface and interacts with large‐scale topographic features such as mountains and deep large craters. In this work, we study the solar wind orographic effects from topographic obstructions along a rough lunar surface. On the leeward side of large obstructions,...
