1. Shadows at the Edge of Lunar Day The Artemis II crew captures a portion of the Moon coming into view along the terminator – the boundary between lunar day and night – where low-angle sunlight casts long, dramatic shadows across the surface. This grazing light accentuates the Moon’s rugged topography, revealing craters, ridges, and basin structures in striking detail. Features along the terminator such as Jule Crater, Birkhoff Crater, Stebbins Crater, and surrounding highlands stand out. From this perspective, the interplay of light and shadow highlights the complexity of the lunar surface in ways not visible under full illumination. The image was captured about three hours into the crew’s lunar observation period, as they flew around the far side of the Moon on the sixth day of the mission. Source:NASA 2. Ready for a Close Up Captured by the Artemis II crew, the heavily cratered terrain of the eastern edge of the South Pole-Aitken basin is seen with the shadowed terminator – the boundary between lunar day and night – at the top of the image. The South Pole-Aitken basin is the largest and oldest basin on the Moon, providing a glimpse into an ancient geologic history built up over billions of years. Source:NASA 3. Shadows Across Vavilov Crater A close-up view taken by the Artemis II crew of Vavilov Crater on the rim of the older and larger Hertzsprung basin. The right portion of the image shows the transition from smooth material within an inner ring of mountains to more rugged terrain around the rim. Vavilov and other craters and their ejecta are accentuated by long shadows at the terminator, the boundary between lunar day and night. The image was captured with a handheld camera at a focal length of 400 mm, as the crew flew around the far side of the Moon. Source:NASA @EverythingScience
