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 …

Araneiforms are enigmatic dendritic negative topography features native to Mars. Found
across a variety of substrates and exhibiting a range of scales, morphologies, and activity …

Upon their discovery in 2000, Martian gullies were hailed as the first proof of recent (ie less
than a few million years) flowing liquid water on the surface of a dry desert planet. Many …

During the Leidenfrost effect, a thin insulating vapor layer separates an evaporating liquid
from a hot solid. Here we demonstrate that Leidenfrost vapor layers can be sustained at …

For decades researchers have used the micro-erosion meter and its successor the
traversing micro-erosion meter to measure micro-scale rates of vertical erosion …

Carbon dioxide is Mars' most active volatile. The seasonal and diurnal processes of when
and where it condenses and sublimates are determined by energy balance between the …

Araneiforms are an exotic type of feature exclusive to the Martian south polar terrain which
have no known direct Earth analog. The dilation and recession of the seasonal CO 2 ice …

Abstract Mars Polar Science is a subfield of Mars science that encompasses all studies of
the cryosphere of Mars and its interaction with the Martian environment. Every 4 yr, the …

Numerous technical scenarios have been developed to facilitate a human return to the
Moon, and as a testbed for a subsequent mission to Mars. Crews appointed with …
