This spectacular view of the crater Degas was obtained as a high-resolution targeted observation (296 feet [90 meters] per pixel). Impact melt coats its floor, and as the melt cooled and shrank, it formed the cracks observed across the crater. For context, Mariner 10’s view of Degas is shown at left. Degas is 32 miles (52 kilometers) in diameter and is centered at 37.1° N, 232.8° E.
