Made of a mass of contradictions, the red planet has long been thought to be the home of little green men.

Made of water, ice,
and solid carbon dioxide,
permanent ice caps at both poles
exhibit a layered structure
with varying concentrations
of dark dust.

Made clear by evidence,
at some time in the past,
some sort of surface fluid
Made large floods,
small river systems,
large lakes
or even oceans.
