– A Youthful Crater in the Cydonia Colles Region

Just what makes a Martian crater youthful, in a geologic sense? Very old craters tend to have eroded rims and can have plenty of material that’s filled in the floor.

– Monitoring Dune Gullies

Remarkably, we have learned that the gullies form primarily or entirely during seasons when there is carbon dioxide frost on the ground.

– Streamlined Landforms near the Cerberus Fossae

One of the earliest observations of Mars that indicated that water once flowed across its surface was the presence of large streamlined landforms.

– Sand Ripples at a Potential Landing Site

Landing of the surface of Mars requires extensive planning and imaging reconnaissance. This terrain west of Aeolis Planum is being considered as landing site for a future Mars mission.
