art002e021296 (April 6, 2026) – As the Artemis II crew flew around the far side of the Moon, they captured key scientific observations, photographs, videos, and records documenting critical observations to help scientists on the ground understand the composition and history of the lunar surface. Near the center of the view lies Hertzsprung basin, an ancient and expansive impact feature described by the Artemis II crew as darker in overall tone compared to surrounding terrain. Crew observations highlight a striking contrast in texture: the interior of Hertzsprung appears unusually smooth, “like a paved road,” while the outer regions transition into rougher, more jagged terrain. Subtle variations in brightness and color across the basin create a patchwork of lighter and darker areas, offering clues to its complex geologic history. Surrounding regions show evidence of ejecta and crater rays, with faint brownish and gray tones radiating across the highlands. Together, these features provide a dynamic view of one of the Moon’s oldest and most intriguing basins. Credit: NASA
