On the basis of geological evidence, it is often stated that the early martian climate was
warm enough for liquid water to flow on the surface thanks to the greenhouse effect of a thick …

Water ice clouds play a key role in the radiative transfer of the Martian atmosphere,
impacting its thermal structure, its circulation, and, in turn, the water cycle. Recent studies …

Isotopic studies indicate that natural perchlorate is produced on Earth in arid environments
by the oxidation of chlorine species through pathways involving ozone or its photochemical …

Atmospheric loss has controlled the history of Martian habitability, removing most of the
planet's initial water through atomic hydrogen and oxygen escape from the upper …

The detection of methane on Mars,, has revived the possibility of past or extant life on this
planet, despite the fact that an abiogenic origin is thought to be equally plausible. An …

The NOMAD spectrometer suite on the ExoMars Trace Gas Orbiter will map the composition
