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.

art002e009299 (April 6, 2026) – Captured from the Orion spacecraft near the end of the Artemis II lunar flyby on April 6, this image shows the Sun beginning to peek out from behind the Moon as the eclipse transitions out of totality. Only a portion of the Moon is visible in frame, its curved edge revealing a bright sliver of sunlight returning after nearly an hour of darkness. In final moments of the eclipse observed by the crew, the reemerging light creates a sharp contrast against the Moon’s silhouette and reveals lunar topography not usually visible along the lunar limb. This fleeting phase captures the dynamic alignment of the Sun, Moon, and spacecraft as Orion continues its journey back from the far side of the Moon.

art002e009301 (April 6, 2026) – Captured by the Artemis II crew during their lunar flyby on April 6, 2026, this image shows the Moon fully eclipsing the Sun. From the crew’s perspective, the Moon appears large enough to completely block the Sun, creating nearly 54 minutes of totality and extending the view far beyond what is possible from Earth. We see a glowing halo around the dark lunar disk. The science community is investigating whether this effect is due to the corona, zodiacal light, or a combination of the two. Also visible are stars, typically too faint to see when imaging the Moon, but with the Moon in darkness stars are readily imaged. This unique vantage point provides both a striking visual and a valuable opportunity for astronauts to document their observations during humanity’s return to deep space. The faint glow of the nearside of the Moon is visible in this image, having been illuminated by light reflected off the Earth.

This image was captured at 6:41 p.m. EDT, on April 6, 2026, just three minutes before the Orion spacecraft and its crew went behind the Moon and lost contact with Earth for 40 minutes before emerging on the other side. In this image, the dark portion of Earth is experiencing nighttime, while on its day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater shows terraced edges and a relatively flat floor marked by central peaks — formed when the surface rebounded upward during the impact that created the crater.

We see a glowing halo around the dark lunar disk. The science community is investigating whether this effect is due to the corona, zodiacal light, or a combination of the two. From this deep-space vantage point, the Moon appeared large enough to sustain nearly 54 minutes of totality, far longer than total solar eclipses typically seen from Earth. The bright silver glint on the left edge of the image is the planet Venus. The round, dark gray feature visible along the Moon’s horizon between the 9 and 10 o’clock positions is Mare Crisium, a feature visible from Earth. We see faint lunar features because light reflected off of Earth provides a source of illumination.

If you look closely, you can see linear, pitted features known as “crater chains” radiating from the Orientale basin, an impact crater with a patch of ancient lava at its center, visible in the bottom center of the image. These crater chains formed about 3.8 billion years ago, when rocks spewed from the collision that formed Orientale landed in lines extending away from the crater. These chains are found near other large craters on the Moon, but we don’t get to see them on Earth because our planet’s crust has been turned over so many times through plate tectonics and largely erased by rain, wind, and ice. In the upper left corner of the Moon disk is a line called the terminator, the boundary between lunar day and night. Here, low-angle sunlight skims the surface, casting dramatic shadows that expose the area’s topography — or the shape of its surface. Glushko crater is the bright spot just to the left of the dark mare, or “sea” of ancient lava flows on the near side of the Moon. It’s identifiable by the bright rays that shoot across the mare, some hundreds of miles away. These rays are made of ejected material after the collision that formed Glushko. Glushko and its rays are brighter than the surrounding area because that younger has experienced less weathering from radiation and impacts. Oceanus Procellarum, the largest lava-filled region on the Moon, spans the horizon. The Aristarchus crater, the bright spot in the sea of lava, creeps toward the right edge of the Moon.

art001e000268 (Nov. 21, 2022) A portion of the far side of the Moon looms large just beyond the Orion spacecraft in this image taken on the sixth day of the Artemis I mission by a camera on the tip of one of Orion’s solar arrays. The spacecraft entered the lunar sphere of influence Sunday, Nov. 20, making the Moon, instead of Earth, the main gravitational force acting on the spacecraft. On Monday, Nov. 21, it came within 80 miles of the lunar surface, the closest approach of the uncrewed Artemis I mission, before moving into a distant retrograde orbit around the Moon.

art002e009286 (April 6, 2026) – 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—formed when the surface rebounded upward during the impact that created the crater.

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. Near the center of the view lies Hertzsprung basin, an ancient and expansive impact feature described by the Artemis II crew as darker in overall tone compared to surrounding terrain. Crew observations highlight a striking contrast in texture: the interior of Hertzsprung appears unusually smooth, “like a paved road,” while the outer regions transition into rougher, more jagged terrain. Subtle variations in brightness and color across the basin create a patchwork of lighter and darker areas, offering clues to its complex geologic history. Surrounding regions show evidence of ejecta and crater rays, with faint brownish and gray tones radiating across the highlands. Together, these features provide a dynamic view of one of the Moon’s oldest and most intriguing basins. Credit: NASA

art002e009277 (April 6, 2026) - 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.

art002e009562 (April 6, 2026) - The Orion spacecraft is seen in the foreground lit up by the Sun. A waxing gibbous Moon is visible in the background. Orientale basin, a 600-mile-wide impact crater ringed by mountains, is visible toward the center bottom of the Moon. This basin straddles the Moon’s near and far sides. To the left of Orientale, which has a patch of ancient lava in its basin, is the far side; this is the hemisphere we don’t get to see from Earth. To the right of Orientale is the near side, the hemisphere we see every day from Earth. The nearside is notable for giant, dark patches of ancient lave flows that cover its surface.

art002e009278 (April 6, 2026) - 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.

art002e009287 (April 6, 2026) – Earth sets at 6:41 p.m. EDT, April 6, 2026, over the Moon’s curved limb in this photo captured by the Artemis II crew during their journey around the far side of the Moon. Orientale basin is perched on the edge of the visible lunar surface. Hertzsprung Basin appears as two subtle concentric rings, which are interrupted by Vavilov, a younger crater superimposed over the older structure. The lines of indentations are secondary crater chains formed by ejecta from the massive impact that created Orientale. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over the Australia and Oceania region.

Artemis I will be the first integrated flight test of NASA’s deep space exploration system: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy Space Center in Cape Canaveral, Florida. The first in a series of increasingly complex missions, Artemis I will be an uncrewed flight that will provide a foundation for human deep space exploration, and demonstrate our commitment and capability to extend human existence to the Moon and beyond. During this flight, the uncrewed Orion spacecraft will launch on the most powerful rocket in the world and travel thousands of miles beyond the Moon, farther than any spacecraft built for humans has ever flown, over the course of about a three-week mission.
