NASA Mars Reconnaissance Orbiter HiRISE Images – June 13, 2012

– Which Crater Came First?

This image shows two craters, both approximately the same diameter but quite different in appearance otherwise. Which one might have formed first?

– Sinuous Ridges in Aeolis Planum

The eroded ridges are located in a trough, while the well-preserved ridges are at higher elevation.

– Wavy-Looking Layers in the North Polar Layered Deposits

These layers near the North Pole of Mars probably record global climate changes, similar to ice ages on Earth.

– Bright Material along the Floor of a Trough in Noctis Labyrinthus

This HiRISE image shows an example of the bright material commonly found along the floors of some of the Noctis Labyrinthus troughs.

All of the HiRISE images are archived here:
