Surface of the moon with many craters

Ready for a Close Up art002e009283 (April 6, 2026) – 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. Image Credit: NASA
