Global dust storms on Mars are rare, but can affect the Martian atmosphere for several
months. They can cause changes in atmospheric dynamics and inflation of the atmosphere …

The loss of water from Mars to space is thought to result from the transport of water to the
upper atmosphere, where it is dissociated to hydrogen and escapes the planet. Recent …

The detection of methane on Mars has been interpreted as indicating that geochemical or
biotic activities could persist on Mars today. A number of different measurements of methane …

It has been suggested that dust storms efficiently transport water vapor from the near‐
surface to the middle atmosphere on Mars. Knowledge of the water vapor vertical profile …

Reports of methane detection in the Martian atmosphere have been intensely debated. The
presence of methane could enhance habitability and may even be a signature of life …

Abstract The Nadir and Occultation for MArs Discovery (NOMAD) instrument on board
ExoMars Trace Gas Orbiter measured a large increase in water vapor at altitudes in the …

A major quest in Mars' exploration has been the hunt for atmospheric gases, potentially
unveiling ongoing activity of geophysical or biological origin. Here, we report the first …
