Summary

[edit]
Description

Radar reveals layers in the mile-thick mountain of ice at the north pole of Mars. The top view shows the topography of the ice cap, which grows and shrinks and adds a new layer of dust and ice each season.

The middle section contains a radar view from the Mars Reconnaissance Orbiter, with alternating bright and dark layers of dust and ice extending back into the history of the Red Planet. Beneath the ice are additional, more opaque layers that may tell the tale of a time when Mars' climate was different.

The bottom section is a visual look at roughly the same region, taken earlier by a different spacecraft, the Mars Odyssey orbiter.
