HiRISE: Textures in Deuteronilus Mensae

This enhanced color image shows the surface of a lobate debris apron in the Deuteronilus Mensae region of Mars, on the boundary between the Northern plains and Southern lowlands. These lobe-shaped formations commonly emanate from mesas in this region and … Continue reading

HiRISE: Go with the (bright) flow

Many slopes in the middle latitudes of Mars show icy flows or glaciers. The region shown here, in the south-facing slope of a crater, is unusual because the flows have bright highlights. The color and brightness variations are likely due … Continue reading

HiRISE: Surface patterns of glacier-like landforms

The rotational axis of Mars is currently tilted by about 25 degrees, very similar to that of the Earth (at 23.4 degrees). However, while Earth’s axial tilt (also known as “obliquity”) tends to change very slightly over time (almost 3 … Continue reading

Mars has mid-latitude belts of glaciers

Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as the surface of the … Continue reading
