Learning outcomesOn successful completion of this module students should be able to:
1. Describe the physical processes that underlie the evolution of the solid planets.
2. Explain how climate is influenced by orbital motion.
3. Describe the evolution of terrestrial and planetary atmospheres. Explain how non-Keplerian orbital motion arises. Explain how observations enable us to probe planetary interiors.
4. Explain the balance of energy in an atmospheric system. Solve simple problems in radiative transfer.
5. Explain the vertical structure of the neutral atmosphere in terms of the underlying physics.
6. Discuss the factors controlling fluid flow above a planetary susface.
7. Use a computational modelling suite to derive flow pattenrs above a planetary surface, display the results using a visualisation system and interpret them in terms of the underlying physics.
8. Use the model results to plan the best path for an airbourne planetary robot to follow above the terrain for specific experiment targets.
8. Present the results in poster form.
This course will provide students with an overview of planetary science, including the constraints on robotic planetary exploration and the use of computational modelling of planetary atmospheres.
