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...

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...

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...

The middle infrared (MIR) channel of the Atmospheric Chemistry Suite (ACS) instrument onboard the ExoMars Trace Gas Orbiter (TGO) 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 d...

Full-text available
The Atmospheric Chemistry Suite (ACS) MIR channel onboard the ESA-Roscosmos Trace Gas Orbiter (TGO) (Korablev et al., 2018, 2019) probes the Martian atmosphere in the 2.3-4.2 µm spectral range using the Solar Occultation technique. ACS-MIR has now provided infrared observations of the Martian atmosphere over more than one and a half regular Martian...
Conference Paper
Full-text available
We report the detection of a new spectral signature around 3 μm specific to the martian northern latitudes and present two putative scenarios to explain it.

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 reprocessed OMEGA/Mars Express observations...
Conference Paper
Full-text available
We present evidence for a new spectral component in the martian 3 microns water band that only appears under north polar latitudes, that may be of importance in the search for the origin of the strong polar increase of the surface aqueous alteration.

ACS Mid InfraRed (MIR) channel notably provides solar occultation observations of the martian atmosphere in the 2.3 – 4.2 μm spectral range. Here we use these observations to characterize water i...
Conference Paper
Full-text available
ACS (the Atmospheric Chemistry Suite) [1] instrument onboard the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO) is dedicated to measurements of the Martian atmosphere, in particular implementing the solar occultation technique for sensitive measurement of trace atmospheric gases TGO has started science observations from April 2018 (Ls=162°; MY34), a...

The Atmospheric Chemistry Suite (ACS) instrument from the ExoMars Trace Gas Orbiter (TGO) ESA-Roscosmos mission has started science operations in March 2018. The middle-infrared (MIR) channel is an infrared spectrometer dedicated to Solar Occultation, covering the 2,3-4,2 µm spectral range. It allows us to monitor the aerosols wavelength behaviour,...
