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

Dust devils: major source of atmospheric dust on Mars and Earth
Swirling columns of sand and dust, known as dust devils, are a feature of desert areas on Mars and on Earth. Now, a study of terrestrial dust devils has shown that around two thirds of the fine particles lifted by … Continue reading
