1. A Moment with the Moon In this view of the Moon, taken by the Artemis II crew at 2:19 p.m. EDT, just before the crew began their observation period, Orientale basin is visible in the center, with a black patch of ancient lava in the center that punched through the Moon’s crust in an eruption billions of years ago. This 600-mile-wide impact crater lies along the transition between the near and far sides and is sometimes partly visible from Earth. The small, bright crater to its left is Byrgius, which has 250-mile rays extending out from its basin. Source: NASA 2. It’s All in the Details During their lunar flyby observation period, the Artemis II crew captured this image at 3:41 p.m. EDT, showing the rings of the Orientale basin, one of the Moon’s youngest and best-preserved large impact craters. These concentric rings offer scientists a rare window into how massive impacts shape planetary surfaces, helping refine models of crater formation and the Moon’s geologic history. At the 10 o’clock position of the Orientale basin, the two smaller craters – which the Artemis II crew has suggested be named Integrity and Carroll – are visible. These features highlight how crew observations can directly support surface feature identification and real-time science. Source: NASA 3. Keeper of the Night Sky Just over half of the Moon fills the left half of the image. The near side, characterized by the dark patches of ancient lava, is visible on the top third of the lunar disk. Orientale basin, a round crater in the center with a black patch of ancient lava in the center, is wrapped in rings of mountains. The round black spot northeast of Orientale is Grimaldi crater, and Aristarchus crater is the bright white dot in the midst of a dark grey lava flow at the top of the image.
