Low-spin ferrous iron suppresses mantle oxidation beyond Earth-like pressures
Alice Girani, Sylvain Petitgirard, Sergey Yaroslavstsev +5
The Earth's mantle has elevated Fe relative to those of other rocky bodies, yet the oxidation- and electronic state of iron at extreme pressures is poorly known. We present…
Estimation of the tidal heating in the TRAPPIST-1 planets. Influence of the internal structure
Emeline Bolmont, Mariana Sastre, Alexandre Revol +2
With the arrival of JWST observations of the TRAPPIST-1 planets, it is timely to reassess the contribution of tidal heating to their heat budget. JWST thermal phase curves could re…
Modeling the formation of N2 and CH4 frost on Pluto's slopes
L. Lange, T. Bertrand, V. Belissa +3
Context. The equatorial region of Cthulhu as revealed by New Horizons appears to be generally dark and largely devoid of volatiles because its surface albedo is low. Localized brig…
Investigating the extent of bladed terrain on Pluto via photometric surface roughness
I. Mishra, R. Dhingra, B. J. Buratti +2
NASA's New Horizons spacecraft discovered fields of sub-parallel sets of steep ridges situated in the high-altitude, low-latitude regions in Pluto's encounter hemisphere called 'bl…
The Atmosphere of Titan in Late Northern Summer from JWST and Keck Observations
Conor A. Nixon, Bruno Bézard, Thomas Cornet +42
Saturn's moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan's northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017)…
Peculiar rainbows in Saturn's E ring: Uncovering luminous bands near Enceladus
Niels Rubbrecht, Stéphanie Cazaux, Benoît Seignovert +4
We report observations of stripe-like features in Enceladus' plumes captured simultaneously by Cassini's VIMS-IR and ISS NAC instruments during flyby E17, with similar patterns see…
Open Questions and Future Directions in Titan Science
Conor A. Nixon, Natalie Carrasco, Christophe Sotin
In this chapter we attempt to distill the very large number of possible future inquiries of Titan into a relatively concise list of twenty high level questions - each of which of w…
Drifts of the sub-stellar points of the TRAPPIST-1 planets
Revol Alexandre, Émeline Bolmont, Mariana Sastre +4
Accurate modeling of tidal interactions is crucial for interpreting recent JWST observations of the thermal emissions of TRAPPIST-1~b and c and for characterizing the surface condi…
Spin evolution of Venus-like planets subjected to gravitational and thermal tides
Alexandre Revol, Émeline Bolmont, Gabriel Tobie +5
The arrival of powerful instruments will provide valuable data for the characterization of rocky exoplanets. It is then crucial to accurately model the dynamical state of exoplanet…
Dynamic reorientation of tidally locked bodies: application to Pluto
Vojtěch Patočka, Martin Kihoulou, Ondřej Čadek
Planets and moons reorient in space due to mass redistribution associated with various types of internal and external processes. While the equilibrium orientation of a tidally lock…
High and dry: billion-year trends in the aridity of river-forming climates on Mars
Edwin S. Kite, Axel Noblet
Mars' wet-to-dry transition is a major environmental catastrophe, yet the spatial pattern, tempo, and cause of drying are poorly constrained. We built a globally-distributed databa…
Tectonics of Cerberus Fossae unveiled by marsquakes
Simon C. Stähler, Anna Mittelholz, Clément Perrin +8
The InSight mission has measured Mars' seismicity since February 2018 and has allowed to investigate tectonics on another planet. Seismic data shows that most of the widely distrib…
Investigating Mercury's Environment with the Two-Spacecraft BepiColombo Mission
A. Milillo, M. Fujimoto, G. Murakami +76
The ESA-JAXA BepiColombo mission will provide simultaneous measurements from two spacecraft, offering an unprecedented opportunity to investigate magnetospheric and exospheric dyna…
Gravitational atmospheric tides as a probe of Titan's interior: Application to Dragonfly
Benjamin Charnay, Gabriel Tobie, Sébastien Lebonnois +1
Context: Saturn's massive gravity is expected to causes a tide in Titan's atmosphere, producing a surface pressure variation through the orbit of Titan and tidal winds in the tropo…
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…
Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
Distribution and intensity of water ice signature in south Xanadu and Tui Regio
Maélie Coutelier, Daniel Cordier, Benoît Seignovert +5
Titan's surface was revealed by Cassini's instruments, showing the presence of liquid hydrocarbons in lakes, and features like dry riverbed. In order to study the sediment transpor…
Iron Mobility During Diagenesis at Vera Rubin Ridge, Gale Crater, Mars
J l'Haridon, N Mangold, A Fraeman +18
The Curiosity rover investigated a topographic structure known as Vera Rubin ridge, associated with a hematite signature in orbital spectra. There, Curiosity encountered mudstones…
Voluminous silica precipitated from martian waters during late-stage aqueous alteration
L. Pan, J. Carter, C. Quantin-Nataf +6
Mars' transition from an early "warm and wet" to the "cold and dry" environment left fingerprints on the geological record of fluvial activity on Mars. The morphological and minera…
Solid tidal friction in multi-layer planets: Application to Earth, Venus, a Super Earth and the TRAPPIST-1 planets. Can a multi-layer planet be approximated as a homogeneous planet?
Emeline Bolmont, Sylvain N. Breton, Gabriel Tobie +3
With the discovery of TRAPPIST-1 and its seven planets within 0.06 au, the correct treatment of tidal interactions is becoming necessary. The eccentricity, rotation, and obliquity…
