Thermophysical Properties of Europa's Surface Constrained by Galileo Photopolarimeter-Radiometer Temperature Measurements
L. Lange, S. Piqueux, P. O. Hayne +10
Thermal measurements constrain the physical properties of icy satellite surfaces, including grain size, porosity, and regolith structure. On Europa, analyses of the Galileo Photopo…
Simulation of laser travel-time on Mercury for BELA
Jean Barron, Frédéric Schmidt, François Andrieu +3
Recent laser altimeters are able to not only measure the ranging distance between the spacecraft and the surface but also the full time-of-flight of the photons or pulse shape. Thi…
The Blinking Crystallinity of Europa: A Competition between Irradiation and Thermal Alteration
Cyril Mergny, Frédéric Schmidt, Felix Keil
The surface of Europa experiences a competition between thermally-induced crystallization and radiation-induced amorphization processes, leading to changes of its crystalline struc…
LunaIcy: Exploring Europa's Icy Surface Microstructure through Multiphysics Simulations
Cyril Mergny, Frédéric Schmidt
A multiphysics simulation model incorporating a sintering model coupled with the MultIHeaTS thermal solver was developed to study the evolution of icy moons' microstructure. The si…
MultIHeaTS: A Fast and Stable Thermal Solver for Multilayered Planetary Surfaces
Cyril Mergny, Frédéric Schmidt
A fully implicit scheme is proposed for solving the heat equation in 1D heterogeneous media, available as a computationally efficient open-source Python code. The algorithm uses fi…
Data availability and requirements relevant for the Ariel space mission and other exoplanet atmosphere applications
Katy L. Chubb, Séverine Robert, Clara Sousa-Silva +52
The goal of this white paper is to provide a snapshot of the data availability and data needs primarily for the Ariel space mission, but also for related atmospheric studies of exo…
Gravity-Induced Ice Compaction and Subsurface Porosity on Icy Moons
Cyril Mergny, Frédéric Schmidt
Our understanding of the surface porosity of icy moons and its evolution with depth remains limited, including the precise scale at which ice compaction occurs under self-weight pr…
Toward a numerical deshaker for PFS
F. Schmidt, I. Shatalina, M. Kowalski +3
The Planetary Fourier Spectrometer (PFS) onboard Mars Express (MEx) is the instrument with the highest spectral resolution observing Mars from orbit since January 2004. It permits…
