Overview of suggested candidate landing sites near the Shackleton crater, shown on the 20 m pixel⁻¹ LRO LDEM topographic base map (M. K. Barker et al. 2023). Black boxes are the two Artemis candidate landing regions “Connecting Ridge” and “Peak Near Shackleton” (NASA 2022b). Candidate landing sites proposed for the CE-7 mission are shown in red (Deep Space Exploration Laboratory 2022), and potential Artemis landing sites are shown as blue triangles (L. Wueller et al. 2026a, 2026b).
