gifmovie:Planet Mercury in amazing color showing rock compositionsNASA has been capturing images of the solar systems smallest planet Mercury for 2 years with its Messenger spacecraft, and has been collecting high resolution color images of the planet. Now the visual data has been stitched together to make a 3D model of the Mercury. “The areas that you see that are orange - those are volcanic plains. There are some areas that are deep blue that are richer in an opaque mineral which is somewhat mysterious - we don’t really know what that is yet. "And then you see beautiful light-blue streaks across Mercury’s surface. Those are crater rays formed in impacts when fresh, ground-up rock is strewn across the surface of the planet.” -- source link
