1) Voyage 2050 ---- Long-term planning of the ESA Science Programme

The next planning cycle in ESA's Science Programme, Voyage 2050, is now underway. Ideas are solicited from the scientific community for the science themes that should be covered during the Voyage 2050 planning cycle, which covers the time period 2035-2050. Deadline for receipt of White Papers: 5 August 2019, 12:00 (noon) CEST.

 a) Membership of Topical Teams

     Scientists working in ESA Member States and with an interest in any topic in space science and in the
     relevant technologies are welcome to apply for membership of the Topical Teams. Space
     science is defined here in a broad sense, including the observation of the Universe, planetary
     science, solar science, study of the space environment, and scientific experiments that can
     carried out from a spacecraft.

    The Topical Teams will be appointed by the Director of Science after the evaluation and recommendations
    of the Senior Committee. It is intended to have a mix of experience represented in each Topical Team
     and early career scientists are specifically encouraged to apply.

    Full details, including information about Voyage 2050, the tasks of the Topical Team members, and
     information needed by applicants, can be found in the Call for Membership of Topical Teams document.

  b) White Papers

     By means of the present Call for White Papers, the Agency is soliciting ideas from the scientific
     community for the science themes that should be covered during the Voyage 2050 planning cycle.

     White Papers are not proposals for specific missions; they should rather argue why a specific scientific
     theme should have priority in the Voyage 2050 planning cycle. At the same time, and to ensure realism
     in the resulting Programme, applicants should briefly illustrate possible mission profiles.

     Any scientist or science team can submit a White Paper, with no limitation in terms of residence or
     nationality. All White Papers must be submitted in English. White Paper lead scientists cannot be members
     of the Topical Teams.

     Full details, including information about Voyage 2050, the requirements for White Papers, and the role these
     will play in formulating the future Science Programme, can be found in the Call for White Papers document.


2) TRAPPIST-1 | 11-14 June 2019 | Liège, Belgium

Dear colleague,

I'm happy to announce you that on June 11-14 will take place at Liege, Belgium, a multidisciplinary conference totally dedicated to the TRAPPIST-1 planetary system. It aims to cover all aspects of the study of TRAPPIST-1, notably:
* The host star TRAPPIST-1 (and other ultracool dwarf stars): structure, evolution, activity, etc.
* Formation, migration, and dynamics of the planets of TRAPPIST-1 (and around other ultracool dwarf stars)
* Exploring ultracool dwarfs (including brown dwarfs) for more TRAPPIST-1-like systems.
* The structure of TRAPPIST-1 planets: observations vs models, evolution, etc.
* The atmospheric properties of TRAPPIST-1 planets: models, evolution (erosion, outgassing, impacts, pre-main-sequence phase, etc.),
* Atmospheric characterization of the planets with JWST and other upcoming facilities, the prospects for liquid water, possible biosignatures and their detectability, etc.
* The possibility of life on TRAPPIST-1 planets: prebiotic chemistry and photosynthesis around ultracool dwarfs, the impact of high-energy radiation and cosmics, tidal locking, lessons from the solar system, etc.

Contributions from all horizons are welcome: stellar physics, exoplanetology, solar system planetology, observational and theoretical astrophysics, astrobiology, etc. The conference will be divided in different sessions, each composed of an invited review talk, several contributed talks, and short poster presentations.

The discovery of TRAPPIST-1 planets triggered the imagination of many artists that integrated them in their works (novels, music, poems, etc). This is why the conference will also include a special session on Thursday 13th called “TRAPPIST-1: between science and fiction”, during which some artists, writers, game developers, etc will present their works related to TRAPPIST-1 to the participating scientists, enabling the two communities to discuss their visions of a fascinating planetary system.

Registrations are opened up to May 15. The deadline for contributed talk propositions is Apr 1st (not a joke).

For more info, please visit the conference website: https://events.uliege.be/trappist-1

Don't hesitate to advertise the conference to any possibly interested colleague, and to display the conference poster on the walls of your institute!

Best wishes,

4) EPSC-DPS Joint Meeting 2019 ---  Genève --- 15-20 septembre 2019

    Date limite pour la soumission des abstracts, le 8 mai: https://administrator.copernicus.org/authentication.php

     a) OPS1 - Ice Giant Systems
        Conveners: D. H. Atkinson
        This session welcomes abstracts addressing all aspects of ice-giants systems including the internal structure of the ice giants, the composition, structure, and processes of and within ice-giant atmospheres, ice-giant magnetospheres, satellites, and rings, and the relationship to exoplanetary systems. The session will comprise a combination of solicited and contributed oral and poster presentations on new and continuing studies of the ice-giant systems and the connection of the ice giants to our current understanding of exoplanetary system

We welcome papers that
Address the current understanding of ice-giant systems, including atmospheres, interiors, magnetospheres, rings, and satellites including Triton;
Advance our understanding of the ice-giant systems in preparation for future exploration, both remote sensing and in situ;
Discuss what the ice giants can tell us about solar system formation and evolution leading to a better understanding of the current structure of the solar system and its habitable zone
Address outstanding science questions requiring future investigations including from spacecraft, remote sensing, theoretical, and laboratory work necessary to improve our knowledge of the ice giants and their relationship to the gas giants and the solar system;
Present concepts for missions, instruments, and investigations to make appropriate and useful measurements.

b) OPS2 --- Saturn system and the Cassini-Huygens mission
Convener: Athena Coustenis
Results related to the Saturnian system from ground-based and Cassini-Huygens mission observations are welcome. All aspects of the system (planet, satellites and rings) will be presented with emphasis on recent results.

   c)  MIT6 -- Interstellar Probe: science, mission designs, opportunities and challenges
        Convener: Michel Blanc
An Interstellar Probe mission would be the first dedicated mission to venture into the unknown space between our star and other potentially habitable planetary systems. The idea was first discussed dating back to 1960 and the concept has been studied by multiple groups since then. The lack of propulsion technologies and launch vehicles have often presented a stumbling block for NASA and other space agencies to move further with these concepts. In 2016, a congressional report recommended NASA to take the enabling steps for an Interstellar scientific probe. A new NASA-funded study is under way to design a pragmatic Interstellar Probe mission with a goal of reaching 1000 AU within 50 years using available or near-term technology. The study objectives are to identify compelling science targets, develop realistic mission concepts and evaluate critical technologies. The cross-disciplinary science targets include exploration of the Very Local Interstellar Medium and its interaction with the heliosphere, characterization of the circum-solar dust disk, exploration of previously unexplored Kuiper Belt Objects, and observation of the extragalactic background light beyond the zodiacal cloud. A vantage point far away from the solar system, naturally enables these observations to be put in the context of other exoplanetary systems and astrospheres. At the same time, Chinese scientists are studying with their space agency CNSA a scenario in which two “Heliospheric Boundary Explorers” would be launched 6 years apart, one towards the “nose” of the Heliosphere, one in the direction of its putative tail, to address scientific objectives partly similar to the ones described in the NASA study. Not only will the synergies between these two missions be particularly valuable, but also both of them will offer unique opportunities for broad international collaborations, including European contributions.
This session will welcome reports on the unique science discoveries enabled by missions to the Interstellar Medium beyond heliospheric boundaries and will discuss their design concepts, enabling technologies and programmatic challenges.

d) EXO5 -- Aerosols and clouds in planetary atmospheres
Convener: P. Lavvas

Atmospheric aerosols and cloud particles are found in every atmosphere of the solar system, as well as, in exoplanets. Depending on their size, shape, chemical composition, latent heat, and distribution, their effect on the radiation budget varies drastically and is difficult to predict. When organic, aerosols also carry a strong prebiotic interest reinforced by the presence of heavy atoms such as nitrogen, oxygen or sulfur.

The aim of the session is to gather presentations on these complex objects for both terrestrial and giant planet atmospheres, including the special cases of Titan’s and Pluto's hazy atmospheres. All research aspects from their production and evolution processes, their observation/detection, to their fate and atmospheric impact are welcomed, including laboratory investigations and modeling.

e) EXO7 --- Planetary Aeronomy – Near and Afar
Convener: Antonio García Muñoz

Space missions, ground-based observations and theory allow for detailed characterization of planetary upper atmospheres in the solar system that provides novel insights into the physical mechanisms at play. At the same time, the detection of short-period extrasolar planets has inspired numerous studies of chemistry, dynamics, and escape of the upper atmospheres of these planets, at more extreme conditions than those found in the solar system. More than ever, it is critical to foster the communication between the communities working on the theoretical and observational aspects of both solar system and exoplanet upper atmospheres. This communication will secure a solid progress in the interpretation of new atmospheric observables and in the implications for e.g. planet demographics.

This session brings together researchers from the solar system and exoplanet communities in an attempt to exchange knowledge and ideas. We welcome papers on all aspects of planetary aeronomy i.e., the science of the upper atmosphere, either in the solar system or exoplanet systems. Suitable papers include results on photochemistry and ionization, magnetosphere-ionosphere coupling, energy balance and circulation, atmospheric escape and evolution as well as new observations and novel observational techniques.

5) Ninth International Conference on Mars ---- Caltech, Pasadena, California  ---- July 22-25

The Ninth International Conference on Mars will be held at the California Institute of Technology (Caltech) in
Pasadena, California, beginning the morning of Monday, July 22, and ending after a full day on Thursday, July 25.

The Mars Exploration Program Analysis Group (MEPAG) meeting is tentatively scheduled at Caltech on Friday, July 26,
following the Ninth International Conference on Mars. (These will be treated as two separate meetings for NASA
conference forecasting purposes. More information on the MEPAG meeting will be posted to the MEPAG website as it
becomes available.)

The Ninth International Mars Conference will be an ideal time to step back and summarize our current understanding
of Mars and the progress we have made so far. The aim of the meeting is to (1) synthesize changed paradigms in Mars
evolution and pull together the breadth of current Mars knowledge; (2) look forward toward the next decades of Mars
exploration; and (3) aid both individual community members’ and larger groups’/institutions’ planning for that next

7) Two exoplanets postdoctoral research positions in Grenoble and Paris (France)

As part of a research project funded by the ANR (Agence Nationale de la Recherche), the SPIRou Legacy Survey team invites applications for two postdoctoral research positions in the field of exoplanets detections and characterization. The positions will be hosted respectively at the Institut de Planétologie et d'Astrophysique de Grenoble (IPAG) and at the Institut d’Astrophysique de Paris (IAP), France, with a preferred starting date between July and October 2019. Both postdocs will be expected to carry out original research in using SPIRou data of the Radial Velocity (RV) survey dedicated to search and characterize exoplanets. The postdoc at IPAG will have to play an important role in the organization and the exploitation of the systematic RV monitoring of nearby M-dwarfs (under the supervision of X. Delfosse); the postdoc at IAP will have to play an important role to exploit the SPIRou RV monitoring of transiting planet candidates (under the supervision of G. Hébrard).

Interested candidates should contact Xavier Delfosse (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.) at IPAG and/or Guillaume Hébrard (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.) at IAP, and send (in a singe pdf file) a CV, a publication list, a motivation letter, a short research statement describing past achievements and future projects, and arrange for up to two letters of recommendation to be sent before 15 th May 2019.


8) POSTDOCTORAL position at ISTerre : X-ray analyses of Mars Returned Samples under quarantine


Université Grenoble Alpes invites applications for a 2-year postdoc position in Earth and Planetary Sciences, devoted to search of life on Earth at the Archean, as well as preparing X-ray analyses protocols under quarantine for Mars Returned Samples. The position can start as early as September 2019, and will be hosted at the Institut de Sciences de la Terre (ISTerre)

The cross-disciplinary project « Origin of Life » (funded by Univ. Grenoble Alpes IDEX, https://origin-life.univ- grenoble-alpes.fr) brings together the expertise of astrophysicists, astrochemists, planetary scientists, prebiotic chemists, biologists, geologists and paleontologists. It aims to understand the chemical processes that have led to life on Earth, to define habitability conditions for both Solar System planets and exoplanets, and to detect the most favorable exoplanets where to search for a putative existence of life in a near future.

The search for traces of life, in situ on planetary bodies, in samples brought back to Earth, or in Archean rocks has become a scientific goal displayed by space missions in progress (ExoMars - ESA, Osiris Rex, Mars 2020 and MSR - NASA, Hayabusa II - Jaxa), or by Origin of Life projects. The scientific issues involve:

- reducing the risk of false positives in the analyses
- controlling the possible degradation of the biological traces during the first diagnostics.
- establishing the absolute elemental composition and chemical environment of the biological traces during the first diagnostics.

Imaging primordial fossil microorganisms on host minerals by advanced non-invasive/non-destructive X-ray imaging methods of high spatial resolution and sensitivity opens new capabilities for Sample Return missions.

11) PhD position at the Unité Matériaux et Transformation (UMET), Université de Lille
Water in chondrites: experimental investigation of water - silicate interactions
           Carbonaceous chondrites are fossilized remnants of the solar system formation. They contain hydrated silicates resulting from water-rock reactions, the nature of which remains puzzling. What was the state of water at the time of hydration - liquid or vapor? Where did it occur – in the protoplanetary disk or within the asteroids?
          This project aims at investigating experimentally the water/silicate interactions in order to understand the conditions of the alteration events (location, temperature, duration). We will focus on how fast water vapor might alter amorphous silicates, one of the major components accreted in chondrites. We will conduct experiments in an environmental cell, explore various conditions (temperature, fH2O, etc...) and a range of precursor compositions. The reaction products are expected to be nanometer-sized, and we will use state-of-the-art transmission electron microscopy (TEM) techniques to reveal their properties. The lab has recently acquired an advanced TEM with a configuration ideal to perform high resolution images, chemical analysis by EDS and electron energy loss spectroscopy (EELS). The environment also offers multiple and complementary analytical instruments. The results will be interpreted in the frame of the protoplanetary disk evolution and the alteration of asteroids.
