This Jupiter System HD DLC (addon) contains high-resolution textures of Jupiter and its major satellites - Amalthea, Io, Europa, Ganymede, and Callisto. It improves the level of detail of these objects compared to the default SpaceEngine installation, and replaces their low-quality JPEG textures with high-quality PNG ones.
