In Acidalia Planitia
Our science goal with this observation is to investigate the structure of the polygonal terrain as well as their superposition and crosscutting relationships with adjacent geologic units and landforms. Targeting high thermal inertial surfaces will help characterize surface materials. Thermal inertia means a material resists temperature changes by storing and releasing heat slowly, keeping its temperature more stable.
