This graphic illustrates where Mars mineral-mapping from orbit has detected minerals that can indicate where a volcano erupted beneath an ice sheet. The site is far from any ice sheet on modern Mars, in an area where unusual shapes have been interpreted as a possible result of volcanism under ice.

This map shows unprecedented detail of local variations in Mars' gravitational pull on orbiters. The gravitational mapping has been applied to map variations in the thickness of the planet's crust and to deduce information about its deeper interior.

This Mars map shows variations in thickness of the planet's crust, the relatively thin surface layer overlying the mantle of the planet. It shows unprecedented detail derived from new mapping of variations in Mars' gravitational pull on orbiters.

Newly detailed mapping of local variations in Mars' gravitational pull on orbiters (center), combined with topographical mapping of the planet's mountains and valleys (left), yields the best-yet mapping of Mars' crustal thickness (right).

This HiRISE image shows gullies on a south-facing slope of a crater touched with late-Spring carbon dioxide frost. At this time of year, only the south-facing slopes of craters retain their frost, while the frost on the north-facing slopes has melted.
