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… Expand

Topics from this paper

Internal structure and early thermal evolution of Mars from Mars Global Surveyor topography and gravity.
TLDR
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. Expand
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 contactExpand
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 southernExpand
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 assessesExpand
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 inExpand
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 topographicExpand
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,Expand
Density of Mars' South Polar Layered Deposits
TLDR
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. Expand
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 hypothesisExpand
Topography and morphology of the Argyre Basin, Mars: implications for its geologic and hydrologic history
Abstract Argyre, located in the southern highlands southeast of Tharsis, is one of the largest impact basins on Mars and formed in Early Noachian time. We use Mars Global Surveyor (MGS) data toExpand

TLDR
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. Expand
