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.
