How is the generalized South Polar Region defined for missions like NASA's Artemis?

Any area within about 10 degrees latitude of the rotational pole

For modern exploration efforts, including NASA's Artemis program, mission planners utilize a broader definition for the target area than just the mathematically exact rotational pole point. The South Polar Region is generally encompassed by a zone extending approximately 10 degrees of latitude surrounding the true rotational pole. This broader definition is employed for engineering flexibility; while the exact pole is mathematically defined for coordinate systems, it may not coincide with the most advantageous geological or resource-rich locations. This 10-degree radius encompasses the critical resources—both the PSRs containing ice and the PELs offering perpetual sunlight—that are the true engineering objectives.
