After focusing more on the planet’s distant past, one of the most exciting aspects of the new study of Mars were the traces of processes reshaping its surface today. Ice was expected to be found frozen into the soil at high latitudes, but now it appeared to move from place to place, around the globe, reshaping the surface and occassionaly producing traces of liquid water.

Aram Chaos crater is an example of one area whic was once underlain with water ice and beneath that, liquid water. After a violent eruption water gushed out and the ground around it collapsed in complex shapes.
