Extensive evidence of landform-scale martian geomorphic changes has been acquired in
the last decade, and the number and range of examples of surface activity have increased …

Mars exhibits diverse surface changes at all latitudes and all seasons. Active processes
include impact cratering, aeolian sand and dust transport, a variety of slope processes …

Before NASA's Dawn mission, the dwarf planet Ceres was widely believed to contain a
substantial ice-rich layer below its rocky surface. The existence of such a layer has …

Recent analysis of radar data from the Mars Express spacecraft has interpreted bright
subsurface radar reflections as indicators of local liquid water at the base of the south polar …

The rapid and nonintrusive deployment of seismic sensors for near-surface geophysical
surveys is of interest to make data acquisition efficient and to operate in a wide variety of …

Abstract Mars Reconnaissance Orbiter (MRO), with its arrival in 2006 and nearly continuous
operation since, has provided data for the study of martian polar processes spanning nine …

Ahuna Mons is a 4 km tall mountain on Ceres interpreted as a geologically young
cryovolcanic dome. Other possible cryovolcanic features are more ambiguous, implying that …

In its polar layered deposits (PLD), Mars possesses a record of its recent climate, analogous
to terrestrial ice sheets containing climate records on Earth. Each PLD is greater than 2​ km …

Many discoveries of active surface processes on Mars have been made due to the
availability of repeat high-resolution images from the High Resolution Imaging Science …

Cryovolcanism, defined here as the extrusion of icy material from depth, may be an
important planetary phenomenon in sha** the surfaces of many worlds in the outer Solar …
