In this course, students learn about the nature and origins of our solar system and the bodies that comprise it. Perhaps more importantly, the course examines how planets and moons are explored that cannot be visited. What can be discerned about the geology and conditions on these distant worlds? Many of the methods of planetary exploration are the same as those used to investigate the Earth, but they may need to be employed in slightly modified fashions. Rather than direct sampling, as can often be done on Earth, remote versions or substitutions are used. Course lectures review what is known and how planetary scientists have developed this body of knowledge. In-class exercises provide hands-on experience with some of these methods. This course provides not only a better understanding of the possibilities and limitations of the tools used in planetary science, but a sense of the excitement associated with space exploration.
