No evidence of magma ocean on Io based on Juno/JIRAM data
Federico Tosi, Alessandro Mura, Francesca Zambon
A recent paper (ref. 1) used infrared images of Io acquired by the Juno/JIRAM instrument to derive a latitudinal dependence of the spectral radiance and conclude that such latitudi…

We report recent observations of lava lakes within patera on Io made by the JIRAM imager/spectrometer on board the Juno spacecraft, taken during close observation occurred in the e…
Observations of Loki Patera by Juno during close flybys
Alessandro Mura, JIRAM-Io team
We used data from the Juno spacecraft to investigate both the spatial and temporal properties of Loki Patera on Io, acquired in two infrared bands between December 2022 and April 2…
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…

Identification of Ammonium Salts on Comet 67P/C-G Surface from Infrared VIRTIS/Rosetta Data Based on Laboratory Experiments. Implications and Perspectives
Olivier Poch, Istiqomah Istiqomah, Eric Quirico +29
The nucleus of comet 67P/Churyumov-Gerasimenko exhibits a broad spectral reflectance feature around 3.2 m, which is omnipresent in all spectra of the surface, and whose attribut…
The surface of (4) Vesta in visible light as seen by Dawn/VIR
B. Rousseau, M. C. De Sanctis, A. Raponi +9
We analyzed the surface of Vesta at visible wavelengths, using the data of the Visible and InfraRed mapping spectrometer (VIR) on board the Dawn spacecraft. We mapped the variation…
The science case for spacecraft exploration of the Uranian satellites: Candidate ocean worlds in an ice giant system
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +15
The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus' five largest '…
Correction of the VIR-visible data set from the Dawn mission at Vesta
B. Rousseau, M. C De Sanctis, A. Raponi +7
This work describes the correction method applied to the dataset acquired at the asteroid (4) Vesta by the visible channel of the visible and infrared mapping spectrometer. The ris…
The surface of (1) Ceres in visible light as seen by Dawn/VIR
B. Rousseau, M. C. De Sanctis, A. Raponi +9
We study the surface of Ceres at visible wavelengths, as observed by the Visible and InfraRed mapping spectrometer (VIR) onboard the Dawn spacecraft, and analyze the variations of…
Infrared detection of aliphatic organics on a cometary nucleus
A. Raponi, M. Ciarniello, F. Capaccioni +28
The ESA Rosetta mission has acquired unprecedented measurements of comet 67/P-Churyumov-Gerasimenko (hereafter 67P) nucleus surface, whose composition, as determined by in situ and…
The Science Case for Spacecraft Exploration of the Uranian Satellites
Richard J. Cartwright, Chloe B. Beddingfield, Tom Nordheim +14
The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moo…
Ammonium salts are a reservoir of nitrogen on a cometary nucleus and possibly on some asteroids
O. Poch, I. Istiqomah, E. Quirico +29
The measured nitrogen-to-carbon ratio in comets is lower than for the Sun, a discrepancy which could be alleviated if there is an unknown reservoir of nitrogen in comets. The nucle…
Correction of the VIR-Visible data set from the Dawn mission
B. Rousseau, A. Raponi, M. Ciarniello +6
Data acquired at Ceres by the visible channel of the Visible and InfraRed mapping spectrometer (VIR) on board the NASA Dawn spacecraft are affected by the temperatures of both the…
GAUSS -- A Sample Return Mission to Ceres
Xian Shi, Julie Castillo-Rogez, Henry Hsieh +26
The goal of Project GAUSS is to return samples from the dwarf planet Ceres. Ceres is the most accessible ocean world candidate and the largest reservoir of water in the inner solar…
Ice Giant Systems: The Scientific Potential of Orbital Missions to Uranus and Neptune
Leigh N. Fletcher, Ravit Helled, Elias Roussos +27
Uranus and Neptune, and their diverse satellite and ring systems, represent the least explored environments of our Solar System, and yet may provide the archetype for the most comm…
