Scientists are particularly interested in exploring the geology of Venus. Because of its similarity with the Earth in size, density, and overall location in the solar system, Venus may offer key insights into the workings of our own planet. Do the familiar processes of volcanism and plate tectonics occur on our sister planet as well as our own? The detailed radar mapping of the planet performed by the Magellan probe has gone a long way toward answering this question.
