Today's image of Mars shows banded features indicative of past (and maybe present) glacial flow in Hellas Basin on Mars. The banded features we see in this HIRISE image are similar to those left on Earth where glaciers once flowed.
Being able to understand these banded features on Mars will help scientists create a better image of what Mars looked like in the past. Being able to map out the Martian past will let scientists determine at which rate the icy glaciers moved. Understanding the Martian past will help us deal with the present and prepare for future exploration.
Just as understanding Earth's past has helped us figure out why different continents have similar features, studying the geologic history of Mars will give us insight into the different features on Mars.
