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.
