PS1 – Space Weather, Climate, Habitability, and Life in (Exo-) Planetary Context
Programme group scientific officer:
John Lee Grenfell
Open Session on Exoplanetary Research
We welcome general contributions in exoplanetary science including detection, characterisation and numerical modelling studies. We particularly welcome cross-disciplinary contributions involving interior-atmosphere, surface-geology, biogeochemistry, stellar-planetary interactions, high energy astro-particles, escape and plasma physics. We further welcome contributions on the climate, composition and interior of Mini Gas Planets and rocky exoplanets including Super-Earths, Earth-like and Venus-like worlds and their timescales of potential habitability.
Space environments of unmagnetized or weakly magnetized solar system bodies and the effects of space weather on these systems
The ionospheres and (induced) magnetospheres of unmagnetized and weakly magnetized bodies with substantial atmospheres (e.g. Mars, Venus, Titan, Pluto and comets) are subject to disturbances due to solar activity, interplanetary conditions (e.g. solar flares, coronal mass ejections and solar energetic particles) or for moons parent magnetospheric activity. They interact similarly as their magnetized counterparts but with scientifically important differences.
As an integral part of planetary atmospheres, ionospheres are tightly coupled with the neutral atmosphere, exosphere and surrounding plasma environment, possessing rich compositional, density, and temperature structures. The interaction among neutral and charged components affects atmospheric loss, neutral winds, photochemistry, and energy balance within ionospheres.
This session invites abstracts concerning remote and in-situ data analysis, modelling studies, comparative studies, instrumentation and mission concepts for unmagnetized and weakly magnetized solar system bodies.
The session solicits contributions that report on nonthermal solar and planetary radio emissions. Coordinated multi-point observations from ground radio telescopes (e.g., LOFAR, LOIS, LWA1, URAN-2, UTR-2) and spacecraft plasma/wave experiments (e.g., Cassini, Cluster, Demeter, Galileo, Juno, Stereo, Ulysses and Wind) are especially encouraged. Presentations should focus on radiophysics techniques used and developed to investigate the remote magnetic field and the electron density in solar system regions, like the solar corona, the interplanetary medium and the magnetized auroral regions. Interest also extends to laboratory and experimental studies devoted to the comprehension of the generation mechanisms (e.g., cyclotron maser instability) and the acceleration processes (e.g., Alfven waves). Further preparations, evaluations, investigations, analyses of forthcoming space missions (like BepiColombo, Juice, Solar Orbiter, Solar Probe, SunRISE, Taranis) are also welcome.
Originally the term ‘space weather’ referred to the way in which “the variable conditions on the Sun can influence, throughout space and in the Earth’s magnetic field and upper atmosphere, the performance of space-borne and ground-based technological systems and endanger human life or health”(1). In the last years it has been extended to all the objects of the Solar Systems, becoming “Planetary Space Weather”.
The different aspects of the interactions induced by the Sun with the many objects of the Solar System should be studied in comparison with the Earth case, to help understanding the processes involved. In fact, possible comparative studies have already proven to be a powerful tool in understanding the different effects and interactions of space weather occurring around all the bodies of the Solar System.
In the present session, we welcome abstracts from all planets’ upstream solar wind activities and their relation to planetary space weather, including especially magnetized bodies (like Mercury, the Earth, Saturn and Jupiter) as well as comparisons with unmagnetized bodies (Mars and Venus).
Nevertheless, a special focus of this session will be on the planet Mercury whose environment in a few years will be the main goal of the dual ESA/JAXA mission BepiColombo. Bepicolombo will perform the first of six flybys at the end of 2021, and will begin its orbiting phase in 2026. One of the two spacecraft, the Japanese MIO, is especially designed to study the magnetospheric environment. Additional instrumentation onboard the European planetary spacecraft, orbiting closer to the planet, will measure the inner magnetosphere interactions with the exosphere and the surface.
In this frame, we welcome studies on:
• magnetosphere-ionosphere coupling dynamics (and auroras where present);
• the solar wind interaction with planets and moons (nb: for smaller bodies refer to session PS2.3 and for pure studies on unmagnetized bodies refer to session PS1.2)
• inter-comparisons of planetary environments;
• observations of space weather effects from space probes and Earth-based instrumentation;
• theoretical modeling and simulations, especially in view of measurement analysis and interpretation;
• potential impacts of space weathering on technological space systems.

PS2 – Small Bodies (dwarf planets, asteroids, comets) to Dust
Programme group scientific officer:
Small Bodies Open (Asteroids, Comets, Meteoroids, and Dust)
This open session covers all aspects of small solar system objects, e.g., comets, asteroids, meteoroids, and dust. Topics include, but are not limited to, dynamics, evolution, physical properties, composition, detection, charging, heating, surface analysis, and further interactions. You are invited to present results obtained from space missions, remote sensing observations, laboratory studies, theory, and numerical simulations. This session also provides a forum for presenting future space missions and instrumentation. We encourage researchers with inter- and multi-disciplinary results.
Solicited contribution will be given by Stavro L. Ivanovski from National Institute for Astrophysics (Italy) on "The latest (dusty) pieces in the Rosetta story."
Particle and plasma interactions in the ionospheres, exospheres and at surfaces of solar system bodies
This session addresses interactions of plasma and (charged) dust in the vicinity and on the surfaces of small solar system objects and in planetary ionospheres, including meteor phenomena. Surface interactions were observed at several different objects including Mercury, Pluto, asteroids, comets, Kuiper belt objects, and a number of moons. Sub-surface layers influence the electromagnetic field locally and, in this way, can be measured remotely. Furthermore, observed surface properties and exospheres are strongly influenced by complex interactions between the dusty/icy regolith, micro-meteoroids, the plasma environment and UV radiation. These processes in turn affect the plasma conditions of the surroundings. A particular case are the moons of the giant planets where interactions occur with the magnetospheres of their host planets. In this session we invite contributions that will move forward our understanding of electromagnetic, surface-plasma and dust-plasma interaction with (small) solar system bodies. The different topics include (but are not limited to) the physics of meteors and of dust in ionospheres, fundamental electromagnetic interactions of satellites enclosed in diverse atmospheric envelopes, the physics of plumes and their influence on the local electromagnetic fields, the electromagnetic effects of sub-surface (magma) oceans, ionospheric phenomena and space weathering of surfaces.
The chat will be divided in two sections:
Topic 1 (14:00 until 14:50): meteors, dust and upper atmosphere
Topic 2 (14:55 until 15:45): rocky and icy bodies in the solar system
PS3 – Terrestrial Planets Systems - Global Settings
Programme group scientific officers:
Evolutionary pathways of terrestrial planets: Interior/exterior coupling, feedbacks and interaction.
In this session, we will share diverse approaches and ideas exploring the evolutionary pathways of terrestrial planets as complex systems. Their evolution is dependent on a wide array of different mechanisms and how they interact together. Based on present-day observation of examples within our Solar System, and simulations, we wish to foster discussion of models of planetary development: is there a general evolution pattern or is the process stochastic? The aim of this session is also to emphasize the importance of coupling between different layers of the terrestrial planets and feedback processes. Those are still often under-explored and have potentially major repercussions on planetary evolution. For example, surface conditions are dependent on atmosphere composition, which results from early and on-going degassing, atmospheric losses and chemistry, and chemical reactions with the surface. In turn, surface conditions can affect the habitability of the planet. Changes in surface temperature affect surface alteration processes as well as volatile exchanges and might even govern the tectonic regime.
We welcome contributions focused on a single terrestrial body as well as from comparative planetology. Both solar system bodies and exoplanets studies are covered. This session will bring together scientists from a wide range of domains, with a multi-disciplinary outlook, and examine how they can affect planetary evolution. Targeted disciplines include planetary structure and composition, mantle dynamics, tectonic regimes, geomagnetism, volcanism, surface interaction/erosion, geochemistry, petrology, remote sensing, structural geology, atmospheric sciences, volatile cycling, climate and habitability.
Atmospheres and exospheres of terrestrial planets, satellites, and exoplanets
This session primarily focuses on the neutral atmospheres of terrestrial bodies other than the Earth. This includes not only Venus and Mars, but also exoplanets with comparable envelopes and satellites carrying dense atmospheres such as Titan or exospheres such as Ganymede. We welcome contributions dealing with processes affecting the atmospheres of these bodies, from the surface to the exosphere. We invite abstracts concerning observations, both from Earth or from space, modeling and theoretical studies, or laboratory work. Comparative planetology abstracts will be particularly appreciated.
Displays will presented in the same order as their numbering.

Planetary Geomorphology aims to bring together geomorphologists who study the Earth with those who work on other bodies such as Mars, Venus, Mercury, the Moon, icy satellites of the outer solar system, comets, and/or asteroids. Studies applicable to landscapes on any scale on any solid body are welcome. We particularly encourage those who use Earth analogues or laboratory/numerical simulation to submit their work. Considered processes could include aeolian, volcanic, tectonic, fluvial, glacial, periglacial, or "undetermined" ones. We especially welcome contributions from early-career scientists and geomorphologists who are new to planetary science. This year our invited speaker Michelle Koutnik will talk about the general theme of ice preservation and landscape erosion during glacial retreat on Earth and Mars.
Open Session on Moon, Mars, Mercury, Venus as terrestrial planets systems
The Open Session on Moon, Mars, Mercury, Venus as terrestrial planets systems aims at presenting highlights of relevant recent results through observations, modelling, laboratory and theory. Key research questions concerning the surface, subsurface, interior and their evolution will be discussed, as well as instruments and techniques from Earth and space.
Advances in geomorphometry and landform mapping: possibilities, challenges and perspectives
Geomorphometry and geomorphological mapping are important tools used for understanding landscape processes and dynamics on Earth and other planetary bodies. Recent rapid growth of technology and advances in data collection methods has made available vast quantities of geospatial data for such morphometric analysis and mapping, with the geospatial data offering unprecedented spatio-temporal range, density, and resolution. This explosion in the availability of geospatial data opens up considerable possibilities for morphometric analysis and mapping (e.g. for recognising new landforms and processes), but it also presents new challenges in terms of data processing and analysis.
This inter-disciplinary session on geomorphometry and landform mapping aims to bridge the gap between process-focused research fields and the technical domain where geospatial products and analytical methods are developed. The increasing availability of a wide range of geospatial datasets requires the continued development of new tools and analytical approaches as well as landform/landscape classifications. However, a potential lack of communication across disciplines results in efforts to be mainly focused on problems within individual fields. We aim to foster collaboration and the sharing of ideas across subject-boundaries, between technique developers and users, enabling us as a community to fully exploit the wealth of geospatial data that is now available.
We welcome perspectives on geomorphometry and landform mapping from ANY discipline (e.g. geomorphology, planetary science, natural hazard assessment, computer science, remote sensing). This session aims to showcase both technical and applied studies, and we welcome contributions that present (a) new techniques for collecting or deriving geospatial data products, (b) novel tools for analysing geospatial data and extracting innovative geomorphometric variables, (c) mapping and/or morphometric analysis of specific landforms as well as whole landscapes, and (d) mapping and/or morphometric analysis of newly available geospatial datasets. Contributions that demonstrate multi-method or inter-disciplinary approaches are particularly encouraged. We also actively encourage contributors to present tools/methods that are “in development”.

Ice Giant System Exploration
This session welcomes abstracts addressing the exploration of ice giants systems, including the internal structure, and atmosphere composition, structure, and processes of the ice giants, as well as ice giant magnetospheres, satellites, and rings. Potential concepts for future ice giant system exploration, instrumentation, technology developments, and international cooperation are also of high interest.
The Juno and Cassini missions investigated Jupiter and Saturn, respectively. Juno is on-going and continues to obtain data from its polar orbit with the goal of understanding Jupiter's origin and evolution by investigating the interior, atmosphere and magnetosphere. As the largest and most massive planets in our solar system, Jupiter and Saturn offer unique insight in the history of our solar system and how planetary systems in general form and evolve. Juno has provided new observations of the global atmospheric structure and composition, storm and lightning distribution and cloud morphology and dynamics. Our view and understanding of Jupiter’s and Saturn’s auroras and magnetosphere are ever-changing as we explore these regions in situ with coordinated efforts from Earth-based observatories such as Hubble, Hisaki, Keck, etc. Constraining the present-day interior structure and dynamics of giant planets is critical to understanding the formation and evolution of planets in our Solar System and beyond. Both the Juno and Cassini have provided a wealth of new measurements, revealing key aspects of the interiors of Jupiter and Saturn for the first time. This session will bring together both observations and theoretical interpretations to improve our understanding of giant planets interiors, atmospheres and magnetospheres. We welcome submissions on wide range of topics, including: gravity science; strong differential rotation (zonal flows); properties of intrinsic (dynamo) magnetic fields; the existence and properties of the central core; bulk composition (including helium and heavy element abundance); as well as formation scenarios and evolutionary pathways. This session includes results from atmospheric and magnetospheric observations (Juno, Cassini and Earth-based) as well as theoretical modeling of atmospheric structure, composition, dynamics, planetary aurorae, magnetospheric dynamics and processes and comparative planetology.

New mission concepts, instruments and enabling technologies for planetary exploration in the next decade
This session is seeking papers that address new mission concepts, instruments and enabling technologies for future planetary science and exploration. In particular, papers describing mission concepts proposed for ESA and international space agency programs are encouraged.
Cartography and mapping are at this time the only means to conduct basic geoscientific studies (on planetary surfaces). The field of Planetary Cartography and Mapping has been stepping out of its niche existence in the last 15 years due to the availability of an unprecedented amount of new data from various planetary exploration missions from different countries and the advent of internet technology that allows to manage, process, distribute, analyze, and collaborate efficiently. Geospatial information system technology plays a pivotal role in this process and essentially all planetary surface science research in this field benefits from this technology and frequent new developments.
With the availability of data and connection, however, comes the challenge of organizing and structuring available data and research, such as maps and newly derived and refined (base) data that is about to enter its new research life cycle.
This session welcomes presentations covering planetary data and its development into cartographic products and maps. This covers aspects of data archival, dissemination, structuring, analyzing, filtering, visualizing, collaboration, and map compilation but is not limited to these topics.
It should also be emphasized that the exchange of knowledge and experiences from the Earth Sciences would be highly beneficial for the Planetary Data Sciences.
Open session on planetary and space instrumentation
