3) GEISA2022 update : call for contributions
The GEISA spectroscopic database, developed and maintained by the LMD (for its scientific part) and AERIS/ESPRI (for its technical part), is preparing its new GEISA2022 update for the end of the year. Since the launch of the European polar satellite METOP (2006, 2012, 2018), GEISA is the reference spectroscopic database for the validation of IASI level 1 data (CAL/VAL activities), but also for the preparation of future space missions (IASI-NG, Merlin, Microcarb). This database includes (currently) the line parameters of 58 molecules, but also data for cross-sections and optical properties of aerosols.

In the context of the new update in 2022, the team in charge at the LMD is launching a call for contributions to integrate the latest spectroscopic data into GEISA2022. This update will also be the occasion for numerous evolutions in the format of the "line parameters" database, in particular by taking into account non-Voigt parameters for the line profile (HTP, speed-dependent, Rautian... etc). The team is also carrying out an important work to validate the new data and to quantify their contribution to the database. More information on

This call is open until 10/31/2022.

Dear Colleagues,
We are happy to announce that the registration for the Hera international workshop (May 30-June 3, Nice) is open, with a deadline on May 15th, 2022.
All the information can be found here:
Registration fees include the five lunches over the week, a diner cocktail on Monday May 30th, and a diner cocktail and ceremony celebrating Hera at the Côte d’Azur Observatory on Wednesday June 1st, including the transport from and to the meeting venue (Hôtel Saint-Paul) and a visit of the instruments and our new amazing multimedia area. A registration for accompanying persons for the Côte d’Azur Observatory evening on June 1st is possible.
The number of participants being limited to 100 persons, we recommend that you register as fast as possible as we will apply the rule "first come first served", on the following website (also indicated in the registration menu of the workshop website):

Oral speakers will be solicited directly by the session organizers. Other participants who would like to bring a poster can do so, and we will arrange a board that can contain up to 20 posters in the meeting room (if we have more than 20 posters, then we can change them during the week).  

Also, note that June 3 is devoted to a restricted meeting of the Hera Science Operation Working Team (SOWT), and members who are solicited to participate will be contacted by the organisation.
After more than two years, this workshop will be our first opportunity, to celebrate in person the approval of Hera at the ESA Ministerial in November 2019 and the amazing new knowledge that the mission will bring. It will contribute, together with DART, to mitigate the asteroid hazard, but also bring new science knowledge on these small worlds, their dynamics, their compositional and physical properties, and on impact physics at asteroid scale.
We are looking forward to your participation and contribution to the important discussions that will take place during the workshop.
Best wishes,
Patrick Michel and Michael Kueppers

7) PhD position in cometary physics | Université Bourgogne Franche-Comté

The chemical composition of comets is an important tool for a good understanding of solar system formation. Thanks to the Rosetta spacecraft and its in situ observations by mass spectroscopy of the comet 67P/Churyumov-Gerasimenko new chemical species in comets have been detected. The objective of this PhD is to use these results to provide the molecular data necessary for detect some of these species in other comets with ground-based facilities. Such molecular data will permit a good modeling of the infrared spectrum of these species and, consequently, will open the possibility of detecting them with the present and future generations of near-infrared spectrometers (such as CRIRES+ at the 8-m Very Large Telescope or futures instruments on the 39-m Extremely Large Telescope).

The PhD student will develop algorithms and codes adapted for large amplitude motions (for internal rotators such as -CH3, -NH2, -OH, -SH). Some computations in quantum chemistry will permit to predict the wavelengths as well as intensities in absorption and emission necessary to the detection of these species. This work will be peformed in collaboration with experimentalists (AILES line of Synchrotron SOLEIL). If it appears that some species could be observed the student will also participate to some analysis of archive data available with 8-m class telescopes of proposals for instruments like CRIRES+.

8) Thèse, HDR, Séminaire
a) Séminaire de la SFE: Recherche de traces de vie microbiennes : attention aux faux amis | Julie Cosmidis | 9 juin
Le prochain webinaire de la Société Française d’Exobiologie aura lieu le Jeudi 9 Juin 2022, à 17h. Julie Cosmidis, Professeure Associée de Géobiologie à l’Université d’Oxford, donnera une conférence en ligne en français au sujet de la difficulté de démêler le vrai du faux dans la recherche de traces de vie microbiennes.

Inscription obligatoire ici :

Résumé: La vie sur Terre fut exclusivement microbienne pour la plus grande partie de son histoire. Ailleurs dans le système solaire, il y a fort à parier que si des organismes vivants – actuels ou fossiles – sont un jour découverts, ceux-ci partageront des caractéristiques de la vie microbienne terrestre. Certaines de ces caractéristiques, telle la petite taille ou la simplicité morphologique, rendent la découverte de traces de vie microbiennes particulièrement difficile. Un phénomène souvent négligé, et compliquant encore d’avantage le travail des paléobiologistes et exobiologistes, est la possibilité pour des processus abiotiques (non biologiques) de produire des objets qui ressemblent morphologiquement et/ou chimiquement à ceux produits par la vie. Lors de ce séminaire, je passerai en revu certains de ces « faux amis » dans la recherche de biosignatures. J’expliquerai aussi que la méconnaissance de ces processus biomimétiques représente un risque important pour notre capacité à interpréter les résultats des missions martiennes actuelles et futures.

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*

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.

6) From Clouds to Planets II: The Astrochemical Link | 3-7 October 2022 | Harnack Hause, Germany

In 2015, we gathered at the Harnack Haus in Berlin to discuss about star and planet formation and the crucial role played by Astrochemistry in our understanding of the various steps that transform an interstellar cloud in stellar systems like our own. It is now time to meet again and present the exciting results that have been achieved in recent years, thanks to ALMA, IRAM, JVLA, GBT, APEX, SOFIA and other facilities, as well as thanks to coordinated efforts in the laboratory and theory (in particular, quantum chemistry and chemical-dynamical models of evolving clouds and disks). This will be important to cast a fresh look into the future, which we already know is going to be bright, thanks to revolutionary telescopes coming up in the near future (such as JWST and ELT) and next decades (SKA and ngVLA).

During the conference, we will make a journey through space and time, starting from interstellar clouds and then moving to cloud filaments and dense cores on the verge of star formation, to protostars and their embedded disks, to planet-forming disks to exoplanet and finally landing in our Solar System, while delving into laboratory facilities and theoretical calculations and simulations. Each evening, before dinner, there will be a general talk on each topic of the conference (the “aperitive talk”), to allow all communities to understand better the “big picture” and to facilitate finding links across disciplines, which always provide fertile ground in our journey towards understanding our astrochemical origins.

Students and young researchers will be encouraged to attend and interact with all participants, to present their work and broaden their horizons. Some financial help will be available for them upon request.

The total number of participants is limited to less than or equal to 120.

8) Exploration of Jupiter’s moons: How American-European collaboration promotes the search for habitable worlds | 6 Avril 2022 (19h CET) | On line

Europe et Ganymède, et potentiellement Callisto, trois lunes de Jupiter, abritent sous leur surface gelée un océan global d’eau liquide maintenu par des sources de chaleur internes. Ces océans suscitent l’engouement et la curiosité de la communauté scientifique : est-il possible qu’ils regroupent les conditions nécessaires au développement de la vie?

Après une introduction sur la Présidence Française du Conseil de l'Union Européenne 2022 et sur la collaboration scientifique Américano-Européenne, nous donnerons la parole à Olivier Witasse (ESA), Julie Castillo-Rogez (NASA/JPL-Caltech), Mathieu Choukroun (NASA/JPL-Caltech) et Elodie Lesage (NASA/JPL-Caltech), qui tentent de percer les secrets des lunes de glaces de Jupiter au travers des missions JUICE (ESA) et Europa Clipper (NASA) qui partiront vers le système de Jupiter en 2023 et 2024. Leur intervention de vulgarisation scientifique ouverte à tout public sera l'exemple d'une collaboration Américano-Européenne efficace qui promeut la recherche de mondes habitables.

Cet événement hybride est organisé par les attachés pour la Science et la Technologie au Consulat général de France à Los Angeles (Karim Belarbi et Clara Devouassoux). Scientifiques et diplomates européens seront à l'écoute des 4 experts à l'Alliance Française de Pasadena. La présentation et les échanges seront en anglais.

Rejoignez l'événement en ligne le 6 Avril 2022 (19h CET) !

c) SETI: Hard Science | Steve Croft | mardi 29 mars à 14h
ID de réunion : 854 1577 2719
Code secret : 837752
The Breakthrough Listen Project, launched in 2015 at the Royal Society in London, is humanity's most comprehensive, sensitive, and intensive search for technosignatures (signs of technology developed by extraterrestrial intelligence). But in addition to the technosignature search, Breakthrough Listen's efforts are benefiting many other areas of astronomy, machine learning, and high performance computing. With some of the most powerful digital spectrometers in the world deployed on some of the world's most capable telescopes (including at NenuFAR), the Listen program has accumulated tens of petabytes of data that it is making available to the public and to the scientific community.

Listen data are being used to understand the physics of fast radio bursts, to search for axion dark matter in the galaxy, to understand the radio frequency interference environment at the telescopes, to train future radio astronomers and the interested public to find signals of interest (such as the Voyager 1 spacecraft) and to develop innovative methods of signal detection and classification using machine learning, including as part of a collaboration with the "Kaggle" data science platform.

As well as these areas of "hard science", Breakthrough Listen also brings rigorous scientific vigor to the challenging task of searching for technosignatures. I will describe how technosignature searches are highly complementary to biosignature searches that have until recently been the main focus for astrobiology research, and highlight some key results from the search so far.

Steve Croft est Directeur de Recherche au Berkeley SETI Research Center, Dept. of Astronomy, UC Berkeley, en charge du programme « Research Experience for Undergraduates ». Il est également Project Scientist Breakthrough Listen au Green Bank Telescope & Adjunct Senior Astronomer au SETI Institute.
