TL;DR: The Mars Orbiter Laser Altimeter (MOLA) has been used to measure the topography, surface roughness, and 1.064-μm reflectivity of Mars and the heights of volatile and dust clouds as mentioned in this paper.
Journal ArticleDOI

David E. Smith,Maria T. Zuber,Maria T. Zuber,Sean C. Solomon,Roger J. Phillips,James W. Head,James B. Garvin,W. Bruce Banerdt,Duane O. Muhleman,Gordon H. Pettengill,Gregory A. Neumann,Gregory A. Neumann,Frank G. Lemoine,James B. Abshire,Oded Aharonson,C. David,Brown,Steven A. Hauck,Anton B. Ivanov,Patrick J. McGovern,H. Jay Zwally,Thomas C. Duxbury +21 more
TL;DR: Elevations measured by the Mars Orbiter Laser Altimeter have yielded a high-accuracy global map of the topography of Mars, which includes the low northern hemisphere, the Tharsis province, and the Hellas impact basin.
Journal ArticleDOI
Internal Structure and Early Thermal Evolution of Mars from Mars Global Surveyor Topography and Gravity
Maria T. Zuber,Maria T. Zuber,Sean C. Solomon,Roger J. Phillips,David E. Smith,G. Leonard Tyler,Oded Aharonson,Georges Balmino,W. Bruce Banerdt,James W. Head,Catherine L. Johnson,Frank G. Lemoine,Patrick J. McGovern,Gregory A. Neumann,Gregory A. Neumann,David D. Rowlands,Shijie Zhong +16 more
TL;DR: 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.
Journal ArticleDOI
The Mars Observer laser altimeter investigation
Maria T. Zuber,David E. Smith,Sean C. Solomon,Duane O. Muhleman,James W. Head,James B. Garvin,James B. Abshire,Jack L. Bufton +7 more
TL;DR: The Mars Observer laser altimeter (MOLA) was used to determine globally the topography of Mars at a level suitable for addressing problems in geology and geophysics as mentioned in this paper.
Journal ArticleDOI
Ancient Geodynamics and Global-Scale Hydrology on Mars
Roger J. Phillips,Maria T. Zuber,Maria T. Zuber,Sean C. Solomon,Matthew P. Golombek,Bruce M. Jakosky,W. Bruce Banerdt,David E. Smith,Rebecca M.E. Williams,Brian M. Hynek,Oded Aharonson,Steven A. Hauck +11 more
TL;DR: The release of carbon dioxide and water accompanying the emplacement of Tharsis magmas may have sustained a warmer climate than at present, enabling the formation of ancient valley networks and fluvial landscape denudation in and adjacent to the large-scale trough.
