Shadows at the Edge of Lunar Day - NASA
Summary: A high-contrast view of the Moon's terminator line, captured by the Artemis II crew on April 6, 2026, highlighting rugged lunar topography.
This image, taken by the Artemis II crew on the sixth day of their mission, captures the Moon along the terminator—the boundary between lunar day and night. The low-angle sunlight creates long, dramatic shadows that accentuate the rugged lunar surface, revealing intricate details of craters such as Jule, Birkhoff, and Stebbins, as well as surrounding highlands. The perspective provides a unique view of the Moon's complex topography that is not visible under full illumination.
