The selection of the Discovery Program InSight landing site took over four years from initial
identification of possible areas that met engineering constraints, to downselection via …

Radar sounding is a powerful geophysical approach for characterizing the subsurface
conditions of terrestrial and planetary ice masses at local to global scales. As a result, a wide …

The presence of liquid water at the base of the martian polar caps has long been suspected
but not observed. We surveyed the Planum Australe region using the MARSIS (Mars …

Thick deposits cover broad regions of the Martian mid-latitudes with a smooth mantle;
erosion in these regions creates scarps that expose the internal structure of the mantle. We …

The HiRISE camera features a 0.5 m diameter primary mirror, 12 m effective focal length,
and a focal plane system that can acquire images containing up to 28 Gb (gigabits) of data …

A committee of the Mars Exploration Program Analysis Group (MEPAG) has reviewed and

Lobate features abutting massifs and escarpments in the middle latitudes of Mars have been
recognized in images for decades, but their true nature has been controversial, with …

Abstract Morphological analyses of Utopia Planitia, Mars, have led to the hypothesis that the
region contains a substantial amount of near‐surface ice. This paper tests this hypothesis …

The Mars Reconnaissance Orbiter (MRO) is the latest addition to the suite of missions on or
