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 …

Reconstruction of the palaeoenvironmental context of Martian sedimentary rocks is central to
studies of ancient Martian habitability and regional palaeoclimate history. This paper reports …

Progress in the geosciences has often followed the same fundamental paradigm for about
two centuries: Earth's present is the key to understanding its past and its future. This concept …

Recent robotic missions to Mars have offered new insights into the extent, diversity and
habitability of the Martian sedimentary rock record. Since the Curiosity rover landed in Gale …

Sand mobilized by wind forms decimeter-scale impact ripples and decameter-scale or larger
dunes on Earth and Mars. In addition to those two bedform scales, orbital and in situ images …

Abstract The Mars Science Laboratory rover Curiosity visited two active wind‐blown sand
dunes within Gale crater, Mars, which provided the first ground‐based opportunity to …

Aeolian ripples are common in sandy environments on Earth and Mars. On Earth, ripples in
sorted dune sands typically are< 1 cm high and are erased in high winds. On Mars in similar …

Wind-blown sand creates multiscale bedforms on Earth, Mars and other planetary bodies.
According to conventional wisdom, decametre-scale dunes and decimetre-scale ripples …

Large ripples with meter‐scale wavelengths are ubiquitous across Mars. Curiosity's traverse
of the Bagnold Dune Field revealed a morphologic diversity of large Martian ripples that …

Although there is little doubt that rivers once flowed on Mars' surface, how sustained and
frequent their flows were remains enigmatic. Understanding the hydrology of early Mars …
