One of the main goals of most ongoing and future space exploration missions is to search for
habitable conditions and potential signs of extraterrestrial life on Solar System bodies …

In situ rover investigations on Mars have discovered manganese oxides as fracture-filling
materials at Gale and Endeavour craters. Previous studies interpreted these minerals as …

The atmosphere of Mars has been studied for many years now by a long series of missions.
The paper focuses on the results obtained by two of these that are led by European …

Aims. The aim of this work is to show that the seasonal changes and vertical distribution
profiles of hydrogen chloride (HCl) on Mars, as observed by the ExoMars Trace Gas Orbiter …

Organic matter is actively searched on Mars with current and future space missions as it is a
key to detecting potential biosignatures. Given the current harsh environmental conditions at …

Measurements of atmospheric methane by the Curiosity rover's SAM-TLS instrument are
providing evidence of seasonality and diurnal variation in concentration. Given methane's …

The abundance of inactive Martian volcanic centres suggests that early Mars was more
volcanically active than today. On Earth, volcanic degassing releases climate-forcing gases …

Many processes have been identified in the Martian subsurface which may produce or
release methane that eventually can be emitted into the atmosphere. Given the wide range …

Measurements of atmospheric methane by the Curiosity rover's SAM-TLS instrument are
providing evidence of seasonality with bimodal peaks in concentration. Given methane's …

Searching for the presence of biosignatures on Mars is central to understanding and
discovering clues to the geological and chemical history of the planet, and may lead us to …
