A patchy CO exosphere on Ganymede revealed by the James Webb Space Telescope
Dominique Bockelée-Morvan, Olivier Poch, Françcois Leblanc +25
Jupiter's icy moon Ganymede has a tenuous exosphere produced by sputtering and possibly sublimation of water ice. To date, only atomic hydrogen and oxygen have been directly detect…

We examine the observed properties of the Nili Fossae olivine-clay-carbonate lithology from orbital data and in situ by the Mars 2020 rover at the Séítah unit in Jezero crater, inc…
The CH abundance in Jupiter's upper atmosphere
A. Sánchez-López, M. López-Puertas, M. García-Comas +3
Hydrocarbon species, and in particular CH, play a key role in the stratosphere--thermosphere boundary of Jupiter, which occurs around the -bar pressure level. Previous analy…
Thermal structure and aerosols in Mars' atmosphere from TIRVIM/ACS onboard the ExoMars Trace Gas Orbiter : validation of the retrieval algorithm
Sandrine Guerlet, N. Ignatiev, F. Forget +12
The Atmospheric Chemistry Suite (ACS) onboard the ExoMars Trace Gas Orbiter (TGO) monitors the Martian atmosphere through different spectral intervals in the infrared light. We pre…
The SuperCam Infrared Spectrometer for the Perseverance Rover of the Mars2020 mission
Thierry Fouchet, Jean-Michel Reess, Franck Montmessin +38
We present the Infrared spectrometer of SuperCam Instrument Suite that enables the Mars 2020 Perseverance Rover to study remotely the Martian mineralogy within the Jezero crater. T…
Pluto's atmosphere observations with ALMA: spatially-resolved maps of CO and HCN emission and first detection of HNC
E. Lellouch, B. Butler, R. Moreno +6
Following the detection of CO and HCN in Pluto's atmosphere, we report on new ALMA observations of Pluto with two main goals: (i) obtaining spatially-resolved measurements (~0.06''…
First direct measurement of auroral and equatorial jets in the stratosphere of Jupiter
T. Cavalié, B. Benmahi, V. Hue +11
Context. The tropospheric wind pattern in Jupiter consists of alternating prograde and retrograde zonal jets with typical velocities of up to 100 m/s around the equator. At much hi…
A stringent upper limit of the PH abundance at the cloud top of Venus
T. Encrenaz, T. K. Greathouse, E. Marcq +7
Following the announcement of the detection of phosphine (PH) in the cloud deck of Venus at millimeter wavelengths, we have searched for other possible signatures of this molec…
18-year long monitoring of the evolution of H2O vapor in the stratosphere of Jupiter with the Odin space telescope
B. Benmahi, T. Cavalié, M. Dobrijevic +14
Comet Shoemaker-Levy 9 impacted Jupiter in July 1994, leaving its stratosphere with several new species, among them water vapor (H2O). With the aid of a photochemical model H2O can…
Herschel map of Saturn's stratospheric water, delivered by the plumes of Enceladus
T. Cavalié, V. Hue, P. Hartogh +13
Context. The origin of water in the stratospheres of Giant Planets has been an outstanding question ever since its first detection by ISO some 20 years ago. Water can originate fro…
In situ Exploration of the Giant Planets
Olivier Mousis, David H. Atkinson, Richard Ambrosi +27
Remote sensing observations suffer significant limitations when used to study the bulk atmospheric composition of the giant planets of our solar system. This impacts our knowledge…
Radiative-equilibrium model of Jupiter's atmosphere and application to estimating stratospheric circulations
