Afzal,Xiaoli Sun +23 more
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
Ascent and eruption of basaltic magma on the earth and moon
Lionel Wilson,James W. Head +1 more
TL;DR: In this paper, the ascent and emplacement of basaltic magma on the earth and moon is modeled by the application of geological and physical observations and constraints, provided that allowance is made for the coalescence of gas bubbles.
Journal ArticleDOI
Recent ice ages on Mars
TL;DR: Evidence is shown that dusty, water-ice-rich mantling deposits on Mars formed during a geologically recent ice age that occurred from about 2.1 to 0.4 Myr ago, a key pacemaker of ice ages on the Earth.
Journal ArticleDOI
Character and Spatial Distribution of OH/H2O on the Surface of the Moon Seen by M3 on Chandrayaan-1

TL;DR: Analysis of recent infrared mapping by Chandrayaan-1 and Deep Impact, and reexamining Cassini data obtained during its early flyby of the Moon, Pieters et al. reveal a noticeable absorption signal for H2O and OH across much of the surface, implying that solar wind is depositing and/or somehow forming water and OH in minerals near the lunar surface, and that this trapped water is dynamic.
