This map shows the frequency of carbon dioxide frost's presence at sunrise on Mars, as a percentage of days year-round. Carbon dioxide ice more often covers the ground at night in some mid-latitude regions than in polar regions, where it is generally absent for much of summer and fall.

The white arrows indicate locations in this scene where numerous seasonal dark streaks, called "recurring slope lineae," have been identified in the Coprates Montes area of Mars' Valles Marineris by repeated observations from orbit.

Blue dots on this map indicate sites of recurring slope lineae (RSL) in part of the Valles Marineris canyon network on Mars. RSL are seasonal dark streaks that may be indicators of liquid water. The area mapped here has the highest density of known RSL on Mars.

This graphic presents Martian atmospheric temperature data as curtains over an image of Mars taken during a regional dust storm. The temperature profiles extend from the surface to about 50 miles up. Temperatures are color coded, from minus 243 degrees Fahrenheit (purple) to minus 9 F (red).

This graphic shows Martian atmospheric temperature data related to seasonal patterns in occurrence of large regional dust storms.

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.

Buzz Aldrin, an Apollo 11 astronaut who walked on the moon, makes a holographic appearance in 'Destination: Mars,' a mixed-reality tour of a part of Mars that NASA's Curiosity rover has explored.

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).

NASA's Mars Reconnaissance Orbiter, nearing the 10th anniversary of its arrival at Mars, used its High Resolution Imaging Science Experiment (HiRISE) camera to obtain this view of an area with unusual texture on the southern floor of Gale Crater.

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.
