Well, yes, but,Mars isn't very interesting in the radio. It is one of the few planets for which astronomers' predictions were accurate. But, we can use radio waves to learn more about the surface of the planet. This is a radar map of the planet. Like the radar image of Mercury, the red areas represent surfaces of high reflectivity. The red regions in the center of the planet are associated with the giant volcanoes located there. |
