There are three large objects in the middle and upper middle of this image. The shadows are longer than the boulders, so that seems unlikely. There are a few spacecraft landing sites nearby. The lowest object, the one located in the center of the image, has a long shadow much like a rocket. The others have shadows that appear more like castles. What are these objects?
