Introduction

     Why is Mars important?

     What will we be studying in this course, and what do we hope to achieve?

 

Mars in the Solar System

     Position and size compared to other planets

     Orbital characteristics, orbital variability, distance to Earth

     Exploration history and future/current missions

 

Physiography

     Topographic data – how was it acquired?

     Hemispheric dichotomy – age, nature, what caused it?

     Impact basins – nature, size, age, effects

     Volcanic features – Tharsis, Elysium, dikes/grabens

     Tectonic features – wrinkle ridges, Valles Marineris, rift valleys

     Fluvial features – outflow channels, valley networks, gullies

 

Geological History

     Crater counting and how to use it

     Crater caveats: are the northern plains really young? Is Tharsis?

     Noachian/Hesperian/Amazonian epochs

     Plate tectonics?
