Elevations from the Mars Orbiter Laser Altimeter (MOLA) have been used to construct a precise topographic map of the martian north polar region. The northern ice cap has a maximum elevation of 3 kilometers above its surroundings but lies within a 5-kilometer-deep hemispheric depression that is contiguous with the area into which most outflow channels emptied. Polar cap topography displays evidence of modification by ablation, flow, and wind and is consistent with a primarily H2O composition… 

Winter clouds over the North Martian Polar Cap

The Mars Orbiter Laser Altimeter (MOLA) experiment, carried on the Mars Global Surveyor spacecraft, has observed echoes from cloud tops on roughly 2.5% of the total data taken above 70°N over the

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 of

Lithospheric Loading by the Northern Polar Cap on Mars

Abstract New topography data for the northern polar region on Mars, returned by the the Mars Orbiter Laser Altimeter (MOLA) during the aerobraking hiatus and science phasing orbits, allow

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

North polar region of Mars: Topography of circumpolar deposits from Mars Orbiter Laser Altimeter (MOLA) data and evidence for asymmetric retreat of the polar cap

We have used high-resolution Mars Orbiter Laser Altimeter (MOLA) data to analyze the topography, morphology, stratigraphy, and geologic history of the Martian north circumpolar deposits. The present

North polar stratigraphy and the paleo-erg of Mars

An accurate self-consistent way of coregistering the imaging and topographic data sets of the Mars Global Surveyor mission was developed and used to begin a stratigraphic analysis of the northern

Martian North Polar Cap Recession: 2000 Mars Orbiter Camera Observations

Abstract The wide-angle cameras of the Mars Orbiter Camera (MOC) on the Mars Global Surveyor have recorded the 2000 recession of the seasonal CO 2 cap in the north polar region from L S =330° to 90°.

The Role of Sublimation for the Formation of the Northern Ice Cap: Results from the Mars Orbiter Laser Altimeter

Abstract The evolutionary history of the martian ice caps is practically unknown, and the caps are key to understanding the climatic history of Mars. Sublimation and ice flow are two hypotheses that

Chasma Boreale, Mars: Topographic characterization from Mars Orbiter Laser Altimeter data and implications for mechanisms of formation

[1] Chasma Boreale, a large reentrant in the north polar cap of Mars, is distinct in scale, detailed topography, and orientation from the spiraling troughs that characterize the majority of the polar
