5) IMA 2022 | July 18th-22nd 2022 | Lyon, France

Dear all,

we cordially invite you to attend the 23rd International Mineralogical Association General Meeting  in the beautiful and vibrant city of Lyon-France (July 18th-22nd 2022), where we will paint mineralogy with the colours of space exploration and contribute to sessions dedicated to the mineralogy of Mars.

There are two complementary sessions:

Alteration mineralogy of Mars: insights from orbit, in situ robotic exploration, and meteorites
Proposers: Erwin Dehouck (LGL-TPE, Lyon, France), Benjamin Bultel (University of Oslo, CEED, Norway), William Rapin (IRAP, Toulouse, France), Joseph Razzell Hollis (JPL, Pasadena, CA, USA)

Although it is a very dry place today, the surface of Mars displays ample evidence for past aqueous activity, including in the mineralogical record. Several decades have passed since the first detection of alteration minerals on the surface of Mars from orbit. Orbital surveys have shown that alteration phases are widespread at the global scale, and their presence in ancient terrains highlights a rich history of early aqueous processes not yet fully understood. In situ missions have provided petrological and geochemical data allowing for the reconstruction of paleoenvironments at the local/regional scale. Together, orbital and in situ observations have revealed multiple complex and long-lived alteration scenarios for ancient Mars. In the last decade, new instruments deployed on the surface of Mars, including the first X-ray diffractometer aboard the Curiosity rover (2012) and a suite of submillimeter analyzers (SuperCam, PIXL and SHERLOC) aboard the Perseverance rover (2021), have brought new ways to detect, identify and characterize the Martian alteration phases. A whole collection of alteration and primary minerals has been thus identified and used to apprehend the geological evolution of the planet. Our perception of the composition of the martian crust evolved from a simple basaltic planet to the detection of alkaline rocks. In parallel, the study of Martian meteorites (including the first Noachian regolith breccia) as well as terrestrial analogs has helped to deepen our understanding of the alteration processes that have occurred on Mars.
In this session, we welcome all contributions that tackle the question of formation mechanisms of Martian alteration phases to explain their observed nature and diversity, or that explore their significance to past climates and habitability of the planet.

Primary mineralogy on Mars : insights from orbit, in situ robotic exploration and meteorites
Proposers: Agnes Cousin (IRAP OMP Toulouse), Olivier Beyssac (IMPMC Sorbonne univ. Paris) & Arya Udry (Univ. Nevada Las Vegas)

During the last decade, the igneous and sedimentary mineralogy and petrology of Mars has known a revolution thanks to several missions: in situ robotic exploration using cutting-edge instruments for mineralogy (NASA Curiosity and Perseverance rovers, CNSA Zhurong rover), new unique martian meteorites (regolith breccia NWA7034/7533, Tissint and many others) and ongoing high-resolution exploration from orbit (MRO/CRISM). Several missions for in situ mineralogical exploration are also scheduled for the coming years (rovers ESA ExoMars, JAXA MMX) with ultimately the return of Martian samples on Earth in the 2030s ! This session welcomes presentations from past/current/future missions and/or studies of meteorites on igneous and sedimentary processes on Mars. Experimental and instrumental contributions or the study of Martian analogs are welcome as well.

Extract of previous email with details of the conference:

The Symposium is organised under the auspices of the Gas Kinetics Group of the Faraday Division of the Royal Society of Chemistry. The Symposium has a long history, dating back to 1967. It has been held every two years, with host cities generally alternating between continental Europe and the English-speaking world, mainly the UK. The Royal Society of Chemistry’s prestigious Polanyi medal is traditionally presented at this Symposium. As the Symposium was unfortunately cancelled in 2020 (it was due to be held at KIT in Karlsruhe, Germany), both the 2020 and the 2022 Polanyi medals will be awarded at the 2022 Symposium.

The Symposium provides an open forum for discussion of the latest experimental and theoretical research on a wide range of topics related to gas-phase chemical kinetics, including: combustion; reaction dynamics; atmospheric, interstellar and planetary chemistry; heterogeneous- and particle-chemistry.

The list of invited speakers includes:

Frédérique Battin-Leclerc, CNRS, Université de Lorraine, Nancy, France*
Basile Curchod, University of Durham, UK
Barbara Ervens, CNRS, University of Clermont Auvergne, France
​Aamir Farooq, KAUST, Saudi Arabia
Brianna Heazlewood, University of Liverpool, UK
Stephen Klippenstein, Argonne National Laboratory, USA**
Paul Seakins, University of Leeds, UK
Donald Truhlar, University of Minnesota, USA

8) PhD position in Laboratory Astrophysics | Department of Molecular Physics of the Institute of Physics of Rennes, France.

The project aims at studying reactive collisions with ions at low-temperature to uncover new routes to complex organic molecules in astrophysical environments.

The selected approach is based on the combination of uniform supersonic flows generated with the CRESU method and mass spectrometry for product detection. The study will be focused on a selection of reactions involving carbonaceous ions identified as major players in the chemistry of Titan's ionosphere and the interstellar medium. The data obtained on the identification of products and their branching ratios will be directly usable in photochemical models of astrophysical environments. The candidate will benefit from the expertise of the Department of Molecular Physics in laboratory astrophysics and in the field of gas-phase physical chemistry in extreme environments.

Candidate profile
We are looking for a good candidate who must have a Master's degree (or equivalent diploma) in physics, physical-chemistry or astrophysics. She/he must have strong aptitudes for experimental work and an inclination for teamwork. Experience in the field of experimental molecular physics or mass spectrometry would be an advantage. Data analysis skills would also be appreciated.

Deadlines and procedure
The position will start on October 1, 2022 for a period of 3 years. The deadline for applications is 08 Jul 2022 but applications will be reviewed as they are received and the position will likely be filled before this date.

Small bodies such as comets, asteroids, and moons, can be covered by a layer of loose grains, referred to as regolith. The shape and size distribution of the surface grains vary drastically from one body to another, and the material properties of the grains are often unknown. The low-gravity found on small bodies coupled with their unknown surface environments makes it difficult to foresee how the bodies’ surface regolith will react to external forces. However, it is essential to understand the link between gravity and granular behavior in order to properly interpret impact events, to determine the origins of unique terrain features, and of course, to predict the outcome of in-situ operations during small body missions. In this thesis, we take a closer look at the dynamics behind slow, granular interactions on small body surfaces. Our work is motivated by the upcoming Martian Moons eXploration mission, which will visit the two moons of Mars and will deploy a wheeled-rover to the surface of the larger moon, Phobos. We use low-velocity impact experiments, single-wheel driving experiments, and numerical simulations per the soft-sphere discrete element method (DEM) to investigate how the low-gravity environment on Phobos will influence the landing, sinking, and rolling behavior of the rover. We demonstrate how these granular interactions scale according to gravity, and we discuss our results within the context of new and existing analytical models from the fields of granular mechanics and terramechanics. Finally, we show how rover-regolith interactions can be used to determine the surface material properties of a small body.

Les petits corps tels que les comètes, les astéroïdes et les lunes peuvent être recouverts d'une couche de grains meubles, appelés régolithe. La forme et la distribution de taille des grains de surface varient considérablement d'un corps à l'autre, et les propriétés physiques des grains sont souvent inconnues. La faible gravité présente sur les petits corps, couplée à leur environnement de surface inconnu, rend difficile de prévoir comment le régolithe de surface se comportera lorsqu’il sera soumis à des forces externes. Cependant, il est essentiel de comprendre le lien entre la gravité et le comportement de ce matériau granulaire afin d'interpréter correctement les impacts, de déterminer les origines des caractéristiques uniques du relief et, bien sûr, de prédire le résultat des opérations in situ lors de missions à destination des petits corps. Dans cette thèse, nous examinons de plus près la dynamique des interactions granulaires à faible vitesse à la surface des petits corps. Ces travaux sont effectués dans le cadre de la mission Martian Moons eXploration, qui visitera les deux lunes de Mars et déploiera un rover à roues à la surface de la plus grande lune, Phobos. Des expériences d'impact à faible vitesse, un banc d'essai de roulage et des simulations numériques (méthode des éléments discrets - DEM) sont utilisés pour étudier comment l'environnement à faible gravité sur Phobos influencera le comportement d'atterrissage, d’enfoncement et de roulage du rover. L'influence de la gravité sur les interactions granulaires est étudiée, et les résultats obtenus sont analysés à l'aide de différents modèles analytiques provenant de la mécanique granulaire et de la géomécanique. Enfin, nous montrons comment les interactions rover-régolithe peuvent être utilisées pour déterminer les propriétés du matériau de surface d'un petit corps.
