ALT The Orion spacecraft captures an image of Earth setting behind the Moon. The metallic grey and white structure of the spacecraft dominates the left side of the image. To the far right, the dusty grey surface of the Moon looms large beside the small blue and white Earth in the far distance. The background of the image is the dark blackness of space. No stars are visible as the high contrast of the Moon and Orion spacecraft wash out the distant stars. Credit: NASA
