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…
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…
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…
