Close-up view of surface textures in the Ma’at region, close to the boundary with Maftet, on the small lobe of Comet 67P/Churyumov–Gerasimenko. In this boundary region the dust that dominates Ma’at seems to thin out towards Maftet, revealing rougher terrain below. In the section shown here the dust shows a pitted texture, which may suggest an ice-rich material that may be undergoing desiccation through sublimation.
The image is a crop from an image taken with the OSIRIS narrow-angle camera on 19 October 2014 from a distance of 8 km from the comet’s surface.
