Learning Objective
I can describe the physical characteristics of Mars.
Key Concepts
The first images of Mars were captured by Mariner 4 in 1965, beginning a new era of exploration.
Scientists divide the surface of Mars into quadrangles to categorize data about events like Mars quakes and potential alien activity.
