UA Scientists Find Evidence for Geologically Recent Shallow Ground Ice at Mars’ Equator The University of Arizona

New high-resolution images from the Mars Orbiter Camera (MOC) show evidence of ground ice on Mars as recently as 10 million years ago. More striking is that the signs of geologically recent ground ice deposits are near Mars’ equator, where ice was probably no deeper than 5 meters (15 feet) below the surface, University of Arizona scientists say. “If ground ice was present within 5 meters of the surface only a few million years ago, it is very likely to persist today within about the upper 10 meters,” said UA planetary sciences Professor Alfred S. McEwen. “This is especially interesting because it is an equatorial region of Mars, more accessible to exploration.”
