Sulfate-dominated sedimentary deposits are widespread on the surface of Mars, which
contrasts with the rarity of carbonate deposits, and indicates surface waters with chemical …

Extensive fields of sub-kilometre-to kilometre-scale mounds, cones, domes, shields, and
flow-like edifices cover large parts of the martian lowlands. These features have been …

The northern plains of Mars cover nearly a third of the planet and constitute the planet's
broadest region of lowlands. Apparently formed early in Mars' history, the northern lowlands …

We have mapped 18,000+ circular mounds in a portion of southern Acidalia Planitia using
their sizes, shapes, and responses in Nighttime IR. We estimate that 40,000+ of these …

For the boundaries of each chronostratigraphic epoch on Mars, we present systematically
derived crater-size frequencies based on crater counts of geologic referent surfaces and …

Mariner 9 and Viking spacecraft images revealed that the polar regions of Mars, like those of
Earth, record the planet's climate history. However, fundamental uncertainties regarding the …

Landform classification and mapping of the Martian surface using Mars orbiter images can
provide an important reference for landing site selection and rovers' traversability evaluation …

Petrologic interpretations of thermal emission spectra from Mars orbiting spacecraft indicate
the widespread occurrence of surfaces having basaltic and either andesitic or partly altered …

A hemispheric dichotomy on Mars is marked by the sharp contrast between the sparsely
cratered northern lowland plains and the heavily cratered southern highlands. Mechanisms …

Abstract The quest for past Martian life hinges on locating surface formations linked to
ancient habitability. While Mars' surface is considered to have become cryogenic~ 3.7 Ga …
