art002e024603 (April 6, 2026) - The Moon appears half-illuminated in this photo captured by the Artemis II crew on flight day 6. The terminator -- the difference between light and darkness -- provides a stark contrast and even greater perspective of the Moon's rocky, uneven, and otherworldly surface features. The near side, which is what we can see from Earth, appears in the dark gray regions at the top of this image.
