Geysers on Mars

Martian geysers (or CO
2
jets
) are putative sites of small gas and dust eruptions that occur in the south polar region of Mars during the spring thaw. "Dark dune spots" and "spiders" – or araneiforms [1] – are the two most visible types of features ascribed to these eruptions.

Martian geysers are putative sites of small-scale jet-like eruptions that are believed to occur in the south polar region of Mars during the spring thaw. "Dark dune spots" and "spiders" are the two most visible types of features ascribed to these eruptions. They are unlike any terrestrial geological phenomenon. The reflectance ( albedo ), shapes and unusual spider appearance of these features have stimulated a variety of hypotheses about their origin, ranging from differences in frosting reflectance to explanations involving biological processes. However, all current geophysical models assume some sort of geyser -like activity on Mars . [1] [2] [3] [4] [5] [6] [7] [8] [9] Their characteristics, and the process of their formation, are still a matter of debate.

Dark Dune Spots (sometimes abreviated DDS ) are Martian features that can be seen mostly in the southern polar region (between 60°-80° latitudes) of the planet, just under the polar ice sheet. The spots were discovered on images acquired by the Mars Global Surveyor during 1998-1999. [1]
