HiRISE: Spiders
Not so itsy, not so bitsy: “Spider formations” are made by the process of sublimation, when a solid (carbon dioxide ice) transforms directly into a gas. Beautiful Mars series.

HiRISE: Honey, I shrunk the mesas
The South Polar residual cap (the part that lasts through the summer) is composed of carbon dioxide ice. Although the cap survives each warm summer season, it is constantly changing its shape due to sublimation of carbon dioxide from steep … Continue reading

HiRISE: On the evolution of spiders
On the evolution of spiders. “Spider” is the informal name we give to these features, which are caused by sublimation, when a solid transforms directly into a gas. Here, it’s carbon dioxide gas that sublimates and creates these patterns. Beautiful … Continue reading

HRSC: Cappuccino swirls at Mars’ south pole
Swirls of chocolate, caramel and cream – this image is definitely one to trigger sweet-toothed cravings. Smooth cream-coloured plateaus surrounded by cocoa-dusted ridges interspersed with caramel-hued streaks create a scene reminiscent of a cosmic cappuccino. This picture is, perhaps surprisingly, … Continue reading
