Why Study Ice on Mars?

On Earth, there’s a plethora of variables driving environmental change, from natural processes to the activities of humans. While Mars is most similar to Earth of all the known extraterrestrial worlds, its climate is still extremely different from our watery abode. The recent discovery of ice on the red planet’s surface has given us a new climate driver to study....
