Hertzsprung in Light and Shadow 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.
