Morphological evidence for ancient channelized flows (fluvial and fluvial-like landforms)
exists on the surfaces of all of the inner planets and on some of the satellites of the Solar …

A committee of the Mars Exploration Program Analysis Group (MEPAG) has reviewed and
updated the description of Special Regions on Mars as places where terrestrial organisms …

Mars accumulated and differentiated into crust, mantle and core within a few tens of millions
of years of Solar System formation. Formation of Hellas, which has been adopted as the …

The early Martian environment is interpreted as warmer and wetter, before a significant
change in its global climatic conditions irreversibly led to the current hyperarid …

The KRC numerical thermal model has been used in the analysis of observations from
virtually all Mars missions with infrared sensors and for the selection of virtually all Mars' …

Recent studies of martian dune and non-dune gullies have suggested a seasonal control on
present-day gully activity. The timing of current gully activity, especially activity involving the …

A decade of high-resolution monitoring has revealed extensive activity in fresh Martian
gullies. Flows within the gullies are diverse: they can be relatively light, neutral or dark …

A new survey of Mars Orbiter Camera (MOC) narrow-angle images of gullies in the 30°–45°
S latitude band includes their distribution, morphology, local topographic setting, orientation …

Gully landforms are commonly taken as evidence for surface liquid water in the recent
geological history of Mars. Repeat observations with the High Resolution Imaging Science …

Martian gully landforms resemble terrestrial debris flows formed by the action of liquid water
and have thus been interpreted as evidence for potential habitable environments on Mars …
