The Atmospheric Chemistry Suite (ACS) instrument onboard the ExoMars Trace Gas Orbiter (TGO) European Space Agency‐Roscosmos mission began science operations in March 2018. ACS Mid‐InfraRed (MIR) channel notably provides solar occultation observations of the Martian atmosphere in the 2.3‐ to 4.2‐ μm spectral range. Here, we use these observations t...
Article
Mars northern polar latitudes are known to harbor an enhanced 3 μm spectral signature when observed from orbit. This may indicate a greater amount of surface adsorbed or bound water, although it has not yet been possible to easily reconcile orbital observations with ground measurements by Phoenix. Here we re-analyzed OMEGA/Mars Express observations...

The middle infrared (MIR) channel of the atmospheric chemistry suite (ACS) instrument onboard the ExoMars Trace Gas Orbiter ESA‐Roscosmos mission has performed Solar occultation measurements of the Martian atmosphere in the 2.3–4.2 μm spectral range since March 2018, which now covers two Martian years (MY). We use the methodology previously develop...

Plain Language Summary The H2O and CO2 ices that form at the surface on Mars play an important role in the exchange between the atmosphere and the surface of the planet. While most of the ice is located within the two polar caps that grew and shrink seasonally, ice is also known to condensate as surface frost during the night and sublimate during t...

Retrieving the optical depth of the Martian clouds (𝜏cld) is a powerful way to monitor their spatial and temporal evolution. However, such retrievals from nadir imagery rely on several assumptions, including the vertical structure of the clouds in the atmosphere. Here we compare the results of cloud optical depth retrievals at 320 nm from the Emira...

European Space Agency’s Mars Express (MEX) has been orbiting Mars for 20 years and its instruments have provided a plethora of observations of atmospheric dust and clouds. These observations have been analysed to produce many unique views of the processes leading to dust lifting and cloud formation, and a full picture of the climatologies of dust a...
Conference Paper
Full-text available
We combine simultaneous observations of water ice clouds on Mars in Solar Occultation with TGO/ACS-MIR and in nadir with EMM/EXI to discuss the impact of using actual cloud profiles versus the typical models when performing nadir retrievals.

The Emirates Mars Mission Hope Probe has been orbiting Mars since February 2021 and has started its science phase on May of that year. We present a summary of the most important results from the mission during its 3 years of orbiting the planet.

The OMEGA-Py Python module is a new powerful set of tools dedicated to the scientific exploitation of data provided by the OMEGA/MEx instrument. It provides a Python 3 alternative to the historical SOFT10 IDL routines, along with additional tools.

Full-text available
Planetary exploration relies considerably on mineral characterization to advance our understanding of the solar system, the planets and their evolution. Thus, we must understand past and present processes that can alter materials exposed on the surface, affecting space mission data. Here, we analyze the first dataset monitoring the evolution of a k...

The EXI instrument onboard the Emirates Mars Mission (EMM) spacecraft has been operating for more than one full Martian year, having entered its extended mission phase on April 1, 2023. The EMM orbit provides diurnal coverage over much of the planet on a time scale of approximately ten days. The observations are typically taken in both the ultravio...

The Emirate Mars InfraRed Spectrometer (EMIRS) instrument onboard the Emirates Mars Mission (EMM) "Hope" probe is a Fourier Transform Infrared spectrometer that is observing the Martian surface and atmosphere between 6 and 100 μm from February 2022. The unique orbit of EMM allows EMIRS to observe the entire Martian disk at each observation, coverin...

Condensation and sublimation of ices at the surface of the planet is a key part of both the Martian H2O and CO2 cycles, either from a seasonal or diurnal aspect. If most of the ices are located within the polar caps, surface frost is known to be formed during nighttime down to equatorial latitudes. The Emirate Mars InfraRed Spectrometer (EMIRS) ins...

Sur Mars, la signature infrarouge majeure de la surface consiste en une large bande d’absorption à 3 µm. Étant principalement associée à la présence de molécules H2O ou de groupes –OH, cette signature témoigne de la présence de glace d’eau ainsi que du niveau d’hydratation des sols ; elle est observée aussi bien en surface qu’au sein de l’atmosphèr...

Article
Seasonal flows on warm slopes, or recurring slope lineae (“RSL”), have been presented as strong evidence for currently flowing water on Mars. This assumption was supported by a correlation between activity and warm temperatures, and by the spectral identification of hydrated salts. Here we first demonstrate that salts spectral identification is not...
