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
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
Rapid reduction of Arctic perennial sea ice
[1] The extent of Arctic perennial sea ice, the year-round ice cover, was significantly reduced between March 2005 and March 2007 by 1.08 x 10 6 km 2 , a 23% loss from 4.69 × 10 6 km 2 to 3.61 × 10 6Expand
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
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
The extreme melt across the Greenland ice sheet in 2012
[1] The discovery of the 2012 extreme melt event across almost the entire surface of the Greenland ice sheet is presented. Data from three different satellite sensors – including the Oceansat-2Expand
Topography of the Moon from the Clementine lidar
Range measurements from the lidar instrument carried aboard the Clementine spacecraft have been used to produce an accurate global topographic model of the Moon. This paper discusses the function ofExpand
Improved estimate of tidal dissipation within Mars from MOLA observations of the shadow of Phobos
[1] We report on new observations of the orbital position of Phobos, the innermost natural satellite of Mars, and show that these observations provide an improved estimate of the rate of tidalExpand
