Scientists have discovered eight locations on Mars where underground ice appears to be exposed on cliff faces
The scarps directly expose bright glimpses into vast underground ice previously detected with spectrometers on NASA’s Mars Odyssey orbiter, with ground-penetrating radar instruments on MRO and on the European Space Agency’s Mars Express orbiter, and with observations of fresh impact craters that uncover subsurface ice. NASA sent the Phoenix lander to Mars in response to the Odyssey findings; in 2008, the Phoenix mission confirmed and analyzed the buried water ice at 68 degrees north latitude, about one-third of the way to the pole from the northernmost of the eight scarp sites.
The important thing about this discovery is that, though we have known for several years that water ice exists underground in the Martian mid-latitudes, this is the first time we have identified specific places there it is exposed and accessible.
Unfortunately, the press release does not provide the specific eight locations, except for the one image, which is located in the southern hemisphere in a region called Promethei Terra, far from areas that have been studied much more extensively. I will do some digging to see if I can identify the other seven locations.
