A new Mars Global Ionosphere-Thermosphere Model (M-GITM) is presented that combines the terrestrial GITM framework with Mars fundamental physical parameters, ion-neutral chemistry, and key radiative processes in order to capture the basic observed fe

[1] Phoenix, the first NASA Mars Scout class mission, was designed to “follow the water” and study the polar region. Landing in late northern spring, Phoenix measured soil chemistry, near-surface water ice, and studied numerous atmospheric proper

[1] This effort advances the exploration of the current Martian water cycle by analyzing the nighttime equatorial water ice deposits in the NASA Ames Mars General Circulation Model (version 2.1). The possibility that the current Martian water cycle p

[1] Water content and burial depths derived from thermal and epithermal neutron currents measured by the Mars Odyssey Neutron Spectrometer are used to determine north to south asymmetries and intercorrelations at high latitudes on Mars. Our goal is t

[1] The atmospheric processes underlying the observed spatial and temporal enhancement of noncondensing gases in Mars' atmosphere are investigated. The Gamma Ray Spectrometer (GRS) on board Mars Odyssey has obtained measurements indicating that the a

[1] One and one half Mars years, from 8 June 2002 to 2 April 2005, of atmospheric argon (Ar) measurements are described and studied in the context of understanding how Ar, a minor constituent of the Martian atmosphere that does not condense at temper

[1] The frequency of occurrence of small-scale convective vortices at the Mars Pathfinder lander location exhibits a diurnal variation similar to terrestrial dust devil observations. The 79 vortices detected via their pressure signatures during the 8
