	Why would we fly to another planet to study its rocks? Drawing on a rich range of sources, this presentation allows the teacher to introduce planetary geology^(topic), something not normally studied until degree level. It uses the narrative^(ta) of the Voyager Probes journey to illustrate the vastness of the solar system^(topic) and also the challenges of designing a spacecraft to travel that far. It ends with a discussion of the history^(topic) of Mars, and how the differences between it and the Earth resulted in Mars loosing its water and atmosphere whereas we have kept ours.
