That’s Enceladus, a tiny water-ice moon orbiting Saturn. The ridges and cracks are ice floes, not too different from what you see on the Earth’s north pole. Note that there’s no solid land under our terrestrial arctic region, and for the same reason we think that Enceladus is actually a global ocean covered with floating ice. The lack of craters is because there are few old features on the moon. The shifting floes erase anything that isn’t young.
