The transport of sand and dust by wind is a potent erosional force, creates sand dunes and
ripples, and loads the atmosphere with suspended dust aerosols. This paper presents an …

Abstract The Colour and Stereo Surface Imaging System (CaSSIS) is the main imaging
system onboard the European Space Agency's ExoMars Trace Gas Orbiter (TGO) which was …

Laboratory experiments indicate that the fluid threshold friction speed, u* tf, required to
initiate fully developed aeolian saltation is much higher on Mars than on Earth. A …

This book describes how sand dunes work, why they are the way they are in different
settings, and how they are being studied. Particular attention is paid to their formation and …

Abstract Aeolian megaripples, with 5‐to 50‐m spacing, are abundant on the surface of Mars.
These features were repeatedly targeted by high‐resolution orbital images, but they have …

The first in situ investigation of an active dune field on another planetary surface occurred in
2015–2016 when the Mars Science Laboratory Curiosity rover investigated the Bagnold …

Abstract The NASA Mars Science Laboratory (MSL) rover, Curiosity, has safely landed near
a 35-km-long dark dune field in Gale Crater on Mars. This dune field crosses the landing site …

The morphology of isolated barchan dunes on Mars and Earth may shed light on the
dynamic conditions that form them, their migration direction and the physical properties of …

With the advent of high resolution imaging, bedform motion can now be tracked on the
Martian surface. HiRISE data, with a pixel scale as fine as 25cm, shows displacements of …

Martian dunes are sculpted by meter‐scale bed forms, which have been interpreted as wind
ripples based on orbital data. Because aeolian ripples tend to orient and migrate …
