Elevations measured by the Mars Orbiter Laser Altimeter have yielded a high-accuracy global map of the topography of Mars. Dominant features include the low northern hemisphere, the Tharsis province, and the Hellas impact basin. The northern hemisphere depression is primarily a long-wavelength effect that has been shaped by an internal mechanism. The topography of Tharsis consists of two broad rises. Material excavated from Hellas contributes to the high elevation of the southern hemisphere and… 

Internal structure and early thermal evolution of Mars from Mars Global Surveyor topography and gravity.

The strength of the lithosphere beneath the ancient southern highlands suggests that the northern hemisphere was a locus of high heat flow early in martian history and the thickness of the elastic lithosphere increases with time of loading in the northern plains and Tharsis.

Possible ancient oceans on Mars: evidence from Mars Orbiter Laser Altimeter data.

High-resolution altimetric data define the detailed topography of the northern lowlands of Mars, and a range of data is consistent with the hypothesis that a lowland-encircling geologic contact

The gravity field of Mars: results from Mars Global Surveyor.

Observations of the gravity field of Mars reveal a planet that has responded differently in its northern and southern hemispheres to major impacts and volcanic processes. The rough, elevated southern

Mars northern plains ocean

Abstract Based on our update to the global map of the proposed paleoshorelines from the 1980s using high-quality global image and topography data acquired since the late 1990s, this chapter assesses

Topography of the North and South Polar Ice Caps on Mars

Recent observations by Mars Orbiter Laser Altimeter have provided high resolution view of the Northern Ice cap [7], compiled on the basis of data returned during Science Phasing Orbit. Starting in

Northern lowlands of Mars: Evidence for widespread volcanic flooding and tectonic deformation in the Hesperian Period

[1] Recent Mars Orbiter Laser Altimeter (MOLA) data have provided a new picture of the Martian northern lowland basin topography and surface roughness. In order to assess detailed topographic

Online Mars digital elevation model derived from profiles

The topography of Mars is a key parameter for understanding the geological evolution of the planet. Since 1997, the Mars Orbital Laser Altimeter (MOLA), launched in the frame of Mars Global Surveyor,

Density of Mars' South Polar Layered Deposits

The results demonstrate that the deposits of south polar layered deposits are probably composed of relatively clean water ice and also refine the martian surface-water inventory.

Outflow Channels May Make a Case for a Bygone Ocean on Mars

High-resolution elevation data from the Mars Orbiter Laser Altimeter (MOLA) onboard the Mars Global Surveyor (MGS) spacecraft have been analyzed recently in Chryse Planitia to test the hypothesis



New radar‐derived topography for the northern hemisphere of Mars

Earth-based radar altimetry data for the northern equatorial belt of Mars (6°S–23°N) have recently been reduced to a common basis corresponding to the 6.1-mbar reference surface. A first look at

The Shape of Mars and the Topographic Signature of the Hemispheric Dichotomy

Reanalysis of occultation data from the Mariner 9 and Viking Orbiter spacecraft to determine the shape of Mars indicated that the hemispheric dichotomy is not a fundamental feature of the shape of

The Shape and Internal Structure of the Moon from the Clementine Mission

Global topographic and gravitational field models derived from data collected by the Clementine spacecraft reveal a new picture of the shape and internal structure of the moon, indicating that the structure and thermal history of the Moon are more complex than was previously believed.

Coastal Geomorphology of the Martian northern plains

The paper considers the question of the formation of the outflow channels and valley networks discovered on the Martian northern plains during the Mariner 9 mission. Parker and Saunders (1987) and

Geology and landscape evolution of the Hellas region of Mars

Hellas basin on Mars has been the site of volcanism, tectonism, and modification by fluvial, mass-wasting, and eolian processes over its more than 4-b.y. existence. Our detailed geologic mapping and

Buried topography of Utopia, Mars: Persistence of a giant impact depression

Knobs, partially buried craters, ring fractures, and some mesas permit a qualitative determination of the topography buried beneath younger northern plains materials. These features are widely

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

Topography of the shield volcano, Olympus Mons on Mars

Olympus Mons, one of the largest known shield volcanoes in the Solar System, covers an area of >3.2 × 105 km2and has a diameter of >600 km, excluding its vast aureole deposits. The structure is five

The MOLA Topographic signature at the crustal dichotomy boundary zone on Mars

MOLA data collected during the aerobraking hiatus provide good longitudinal sampling of the crustal dichotomy boundary zone in eastern Mars and reveal a significant topographic signature associated
