WebOct 13, 2009 · Cryopegs are isolated lenses or pockets of highly saline, liquid water that is permanently subzero (Celsius) in temperature due to chilling by the surrounding permafrost. The search for unfrozen Martian niches has expanded with the discovery of seasonally recurring linear features on slopes which might or might not be associated with cryopegs.

WebApr 13, 2024 · April 13, 2024. Expanded craters on Mars are thought to occur when the upper slopes of an impact crater in an ice-rich target sublimate (going directly from a solid to a gaseous state). The vaporizing ice makes the walls retreat while the lower slopes are armored by dust and debris, resulting in a funnel-shaped formation.
