HiRISE: Dunes and ripples in Olympia Undae
Olympia Undae is a large field of sand dunes surrounding Mars’ North Polar ice cap. Because of the high latitude of the dunes, they are covered with water and carbon dioxide frost in the winter and are poorly illuminated. They … Continue reading

HiRISE: Dramatic dune destination
This image of a sand dune field in a southern highlands crater was acquired when the Sun was just 5 degrees above the horizon. As a result, the image is mostly shadows, with sharply-delineated dune crests sticking up into the … Continue reading

HiRISE: Sand dunes in spring
Mars’ northern-most sand dunes are beginning to emerge from their winter cover of seasonal carbon dioxide (dry) ice. Dark, bare south-facing slopes are soaking up the warmth of the sun. The steep lee sides of the dunes are also ice-free … Continue reading

HiRISE image: Dunes in formation
Migratory birds and military aircraft — like during World War II — often fly in a V-shaped formation. The “V” formation greatly boosts the efficiency and range of flying birds, because all except the first fly in the upward motion … Continue reading
