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 …

Methane on Mars is a topic of special interest because of its potential association with
microbial life. The variable detections of methane by the Curiosity rover, orbiters, and …

The ExoMars Trace Gas Orbiter (TGO)'s Colour and Stereo Surface Imaging System
(CaSSIS) provides multi-spectral optical imagery at 4–5 m/pixel spatial resolution. Improving …

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 …

The mid-to high latitudes of Mars host assemblages of landforms consistent with a receding
glacial landscape on Earth. These landforms are postulated to have formed> 5 Ma under a …

Geomorphic and geophysical evidence supports a debris-covered glacier origin for a suite
of landforms at the mid-latitudes of Mars, including lobate debris aprons (LDA), lineated …

We reanalyse the global distribution of gullies in order to provide a set of observational
constraints that models of gully formation must explain. We validate our results derived from …

The localized loss of near‐surface excess ice on Mars by sublimation (and perhaps melting)
can produce thermokarstic collapse features such as expanded craters and scalloped …

Abstract Ancient stratigraphy on Isidis Basin's western margin records the history of water on
early Mars. Noachian units are overlain by layered, basaltic composition sedimentary rocks …

Water is one of the most common and important volatiles found throughout the Solar System,
influencing both the geological evolution of planetary bodies and their potential habitability …
