1. Peeking at the Earth As the Artemis II crew came close to passing behind the Moon and experiencing a planned loss of signal, they captured this image of a crescent Earth setting on the Moon’s limb. The edge of the visible surface of the Moon is called the “lunar limb.” Seen from afar, it almost looks like a circular arc – except when backlit, as in other images captured by the Artemis II crew. In this photo, the dark portion of Earth is experiencing nighttime, while Australia and Oceania are in the daylight. In the foreground, the Ohm crater is visible, with terraced edges and a flat floor interrupted by central peaks. Peaks such as these form in complex craters when the lunar surface is liquified on impact, and the liquefied surface splashes upward during the crater’s formation. Source: NASA 2. The Edge of Two Worlds Our planet draws closer to passing behind the Moon in this image captured by the Artemis II crew during their lunar flyby, about six minutes before Earthset. Earth is in a crescent phase, with sunlight coming from the right. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over muted blue in the Australia and Oceania region. Source: NASA 3. Earthset Over the Lunar Limb Earth appears tiny as the Moon looms large in this photo taken by the Artemis II crew during their lunar flyby on April 6, 2026. Taken 36 minutes before Earthset, our home planet is visible in the blackness of space off the limb of the illuminated Moon. Earth is in a crescent phase, with sunlight coming from the right. Orientale mare basin, with its dark floor of cooled lava and outer rings of mountains, covers nearly the lower third of the imaged lunar surface. Different colors in the mare hint at its mineral composition. The lines of small indentations above Orientale are secondary crater chains, formed by material ejected during a violent primary impact. Both of the new craters that the Artemis II crew has suggested names for – Integrity and Carroll – are in full view. The edge of the visible surface of the Moon is called the “lunar limb.” Seen from afar, it almost looks like a circular arc – except when backlit, as in other images captured by the Artemis II crew.
