Grid Mapping the Northern Plains of Mars: Geomorphological, Radar, and Water‐Equivalent Hydrogen Results From Arcadia Plantia

A project of mapping ice‐related landforms was undertaken to understand the role of subsurface ice in the northern plains. This work is the first continuous regional mapping from CTX (ConTeXt Camera,

Radar sounder evidence of thick, porous sediments in Meridiani Planum and implications for ice‐filled deposits on Mars

Meridiani Planum is one of the most intensely studied regions on Mars, yet little is known about the physical properties of the deposits below those examined by the Opportunity rover. We report the

Widespread Shallow Water Ice on Mars at High Latitudesand Midlatitudes

We derive the depth of the water ice table on Mars by fitting seasonal surface temperature trends acquired by the Mars Climate Sounder and Thermal Emission Imaging System with a two‐layer regolith

The Mars Orbiter for Resources, Ices, and Environments (MORIE) Science Goals and Instrument Trades in Radar, Imaging, and Spectroscopy

The Mars Orbiter for Resources, Ices, and Environments (MORIE) was selected as one of NASA’s 2019 Planetary Mission Concept Studies. The mission builds upon recent discoveries and current knowledge

Geomorphological Evidence for Shallow Ice in the Southern Hemisphere of Mars

The localized loss of near‐surface excess ice on Mars by sublimation (and perhaps melting) can produce thermokarstic collapse features such as expanded craters and scalloped depressions, which can be

Exploring the Shallow Subsurface of Mars with the Ma_MISS Spectrometer on the ExoMars Rover Rosalind Franklin

An essential part of the Exomars 2022 payload is the Mars Multispectral Imager for Subsurface Studies (Ma_MISS) experiment hosted by the drill system. Ma_MISS is a visible and near-infrared (0.4–2.3

Image Reconstruction Techniques in Neutron and Gamma Ray Spectroscopy: Improving Lunar Prospector Data

We present improved resolution maps of the Lunar Prospector Neutron Spectrometer thermal, epithermal, and fast neutron data and gamma ray spectrometer Th‐line fluxes via global application of pixon

Water on Mars—A Literature Review

To assess Mars’ potential for both harboring life and providing useable resources for future human exploration, it is of paramount importance to comprehend the water situation on the planet.



Mars Odyssey neutron data: 2. Search for buried excess water ice deposits at nonpolar latitudes on Mars

[1] Global maps of hydrogen abundance near the surface of Mars, interpreted as the mass percent of water-equivalent hydrogen (WEH) have been generated from measurements of neutron leakage fluxes from

Global distribution of near-surface hydrogen on Mars

[1] Neutron data observed using the Neutron Spectrometer aboard 2001 Mars Odyssey provide a lower limit to the global inventory of Martian water-equivalent hydrogen. Hydrogen-rich deposits ranging

Hydrous minerals on Mars as seen by the CRISM and OMEGA imaging spectrometers: Updated global view

The surface of Mars has preserved the record of early environments in which its basaltic crust was altered by liquid water. These aqueous environments have survived in the form of hydrological

Evidence from the Mars Express High Resolution Stereo Camera for a frozen sea close to Mars' equator

High Resolution Stereo Camera images from the Mars Express spacecraft indicate that evidence is consistent with a frozen body of water, with surface pack-ice, around 5° north latitude and 150° east longitude in southern Elysium, which is a place that might preserve evidence of primitive life, if it has ever developed on Mars.

Ice concentration and distribution near the south pole of Mars: Synthesis of odyssey and global surveyor analyses

Mars Odyssey Gamma‐Ray Spectrometer (GRS) neutron spectrometer data are analyzed to determine the concentration and boundary of buried water ice near the south pole. The measurements are consistent

Mars Odyssey neutron data: 1. Data processing and models of water‐equivalent‐hydrogen distribution

[1] For more than 7 years, the Los Alamos built Mars Odyssey Neutron Spectrometer (MONS) has measured the neutron albedo from Mars in three consecutive energy bands: thermal, epithermal, and fast

Models of the distribution and abundance of hydrogen at the lunar south pole

Permanently shadowed locations at the lunar poles are potential sites for significant concentrations of cold‐trapped volatiles, including water ice. Hydrogen enhancements are seen at the poles, but

Global Distribution of Neutrons from Mars: Results from Mars Odyssey

Global distributions of thermal, epithermal, and fast neutron fluxes have been mapped during late southern summer/northern winter using the Mars Odyssey Neutron Spectrometer, and portions of the low to middle latitudes indicate subsurface deposits of chemically and/ or physically bound H2O and/or OH.

Characterization of Mars' seasonal caps using neutron spectroscopy

[1] Mars' seasonal caps are characterized during Mars years 26 and 27 (April 2002 to January 2006) using data acquired by the 2001 Mars Odyssey Neutron Spectrometer. Time-dependent maps of the column
