The main objective of the mission is to study the south pole of the moon

As the southern polar region points to the sun during the Martian summer, carbon dioxide, which is frozen in the polar cap, is evaporated.

Since the southern polar region is facing the Sun in summer, the frozen carbon dioxide contained in the polar cap begins to evaporate.

Since the southern polar region is pointed towards the Sun in the summer, carbon dioxide frozen in the polar cap evaporates.

Because the Antarctic region in summer, facing the Sun, the frozen carbon dioxide contained in the polar cap begins to evaporate.

Compared to much of the moon's southern hemisphere—the south polar region in particular—the north polar region is much older and covered with craters.

In particular, Cassini discovered water-rich plumes venting from the South Polar Region.

New images show that compared to much of the southern hemisphere on Enceladus--the south polar region in particular--the north polar region is much older and pitted with craters of various sizes.
