The outgassing history of Mars and the prevailing temperature conditions suggest that ground ice may occur to depths of kilometers over large areas of the planet. The presence of permafrost is also indicated by several topographic features that resemble those found in periglacial regions of the earth. East of Hellas and in the Protonilus and Nilosyrtis regions there are features that resemble those formed on earth by gelifluction, the slow creep of near-surface materials aided by freeze-thaw of… 

Mars and Earth: Comparison of cold-climate features

The stability of ground ice in the equatorial region of Mars

Consideration of the partial pressure of H2O in the Martian atmosphere and the range of mean annual temperatures at the Martian surface suggests that the occurrence of ground ice in equilibrium with

Geomorphologic Evidence for Ground Ice on Mars

For ground ice to exist on Mars, two conditions have to be met. One is the presence of permafrost; the second is the availability of water. Because the mean temperature of Mars’surface is − 80 C.,

The subglacial birth of Olympus Mons and its aureoles

The vast volcanic plains and shields of Mars, together with the thermal, spectrographic, and morphological evidence for water ice at the poles, for several percent water in Viking soil samples, for

A thermodynamical study of the Martian permafrost

An outstanding result of the Viking mission has been the detection of water vapor in the martian environment. The only possible reservoir for the water, where no evidence of surface frost has been

Volcanism on Mars

More than 15 years of planetary exploration of Mars have given insight into the geologic processes that have shaped its surface. The newly acquired Viking data have shown that volcanism is one of the

Ice in the northern lowlands and southern highlands of Mars and its enrichment beneath the Elysium lavas

A comprehensive study of the Elysium region has revealed evidence of widespread ground-ice, whose concentration and depth has varied considerably. Ejecta mobility and crater morphology analyses of a

Permafrost and Periglacial Processes on the Martian Surface

Following the development of high-resolution imaging, digital elevation models, thermal and hydrological data, and onsite ground information during the early period of the 21st century, the



Martian impact craters and emplacement of ejecta by surface flow

Several types of Martian impact craters have been recognized. The most common type, the rampart crater, is distinctively different from lunar and Mercurian craters. It is typically surrounded by

Some Martian volcanic features as viewed from the Viking orbiters

The plains to the south and southwest of Arsia Mons are composed of elongate lava flows, many of which appear to originate at a reentrant in the Arsia Mons edifice. Individual flows can be traced for

The surface of Mars 2. Uncratered terrains

Mariner 6 and 7 photographs reveal two types of uncratered terrain on Mars. These are descriptively termed chaotic and featureless. Chaotic terrain is younger than cratered terrain and displays

The thermal state and internal structure of Mars

The evolution and state of the interior of Mars are studied through the use of theoretically calculated thermal history and density models. These models satisfy the constraints of mean density,

Classification and time of formation of Martian channels based on Viking data

Fluviatile and volcanic Martian channels, first discovered on Mariner 9 pictures, have been reexamined by using Viking orbital photography. The superior discrimination of the Viking photographs,

The martian surface.

With the scarcity of factual data and the difficulty of applying crucial tests, many of the properties of the Martian surface remain a mystery; the planet may become a source of great surprises in

Frost Phenomena on Mars

The hypothesis that the Martian wave of darkening might be a frostheaving phenomenon has been examined and it is concluded that without strongly deliquescent salts to attract and retain liquid water in the Martian soil, frost-heaving phenomena are not to be expected on Mars.

Latitudinal distribution of a debris mantle on the Martian surface

Mariner 9 narrow angle pictures show that many areas on Mars are buried by debris mantles that later have been partially eroded. A survey of the present debris distributions shows that they are
