Role of temperature‐dependent viscosity and surface plates in spherical shell models of mantle convection
Layered viscosity, temperature-dependent viscosity, and surface plates have an important effect on the scale and morphology of structure in spherical models of mantle convection. We find thatExpand
Mars Orbiter Laser Altimeter: Experiment summary after the first year of global mapping of Mars
The Mars Orbiter Laser Altimeter (MOLA), an instrument on the Mars Global Surveyor spacecraft, has measured the topography, surface roughness, and 1.064-μm reflectivity of Mars and the heights ofExpand
Resolution of crustal structure of {Mars} from gravity and topography
[1] Mars Orbiter Laser Altimeter (MOLA) topography and gravity models from 5 years of Mars Global Surveyor (MGS) spacecraft tracking provide a window into the structure of the Martian crust and upperExpand
Seasonal Variations of Snow Depth on Mars
TLDR
Using topography collected from the Mars Orbiter Laser Altimeter on the MGS spacecraft, temporal changes in the elevation of the martian surface that correlate with the seasonal cycle of carbon dioxide exchange between the surface and atmosphere are measured. Expand

TLDR
Observations point to a dynamically active interior in the early phases of martian history, followed by a rapid fall-off in heat transport that significantly influenced the geological, geophysical and geochemical evolution of the planet, including the history of water and climate. Expand
Ancient Geodynamics and Global-Scale Hydrology on Mars
TLDR
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. Expand
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
The Crust of the Moon as Seen by GRAIL
TLDR
The Moon's gravity field shows that the lunar crust is less dense and more porous than was thought, and high-resolution gravity data obtained from the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft show that the bulk density of the Moon's highlands crust is substantially lower than generally assumed. Expand
Mars high resolution gravity fields from MRO, Mars seasonal gravity, and other dynamical parameters
Abstract With 2 years of tracking data collection from the MRO spacecraft, there is noticeable improvement in the high frequency portion of the spherical harmonic Mars gravity field. The new JPL MarsExpand
The global topography of Mars and implications for surface evolution.
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,Expand
