Submit your abstracts for EPSC2021 before 26 May: Reminder of TP (Terrestrial Planets) sessions
The coordinators of the EPSC2021 Terrestrial Planets (TP) program invite scientists to participate in the congress, submit contributions and share their research with colleagues and friends. This year we have organised a rich program which includes the following sessions:
TP1 – Planetary Dynamics: Shape, Gravity, Orbit, Tides, and Rotation from Observations and Models
Shape, gravity field, orbit, tidal deformation, and rotation state are fundamental geodetic parameters of any planetary object. Measurements of these parameters are prerequisites for e.g. spacecraft navigation and mapping from orbit, but also for modelling of the interior and evolution. This session welcomes contributions from all aspects of planetary geodesy, including the relevant theories, observations and models in application to planets, satellites, ring systems, asteroids, and comets.

TP3 – Multi-disciplinary perspective on late accretion processes: from impact processes to early differentiation
Late accretion onto the terrestrial planets is of critical importance for understanding the early chemical differentiation processes and the evolution of the terrestrial planets in the solar system. This session aims at obtaining an integrated understanding of these processes from a multidisciplinary perspective. The session aims at bringing together geodynamics, (isotope) geo- and cosmochemistry, experimental petrology, and numerical modeling with a particular focus on the Earth, Moon and Mars.
We welcome contributions from any of these disciplines, especially contributions aimed at improving our current understanding of key processes involved in the early evolution of the terrestrial planets including the provenance and composition of late accreted bodies, the role of giant impacts in volatile loss processes and core formation, the formation and evolution of magma oceans, early convection processes in planetary mantles, and the cooling history of terrestrial planets.

TP4 – Impact Processes in the Solar System
mpact processes shaped the Solar System, and modify planetary surfaces and small bodies until today. Impacts also have a technical application for Planetary Defence, exemplified by the joint ESA/NASA Asteroid Impact and Deflection Assessment (AIDA) collaboration. This session aims at understanding impact processes at all scales in terms of shock metamorphism, dynamical aspects, geochemical consequences, environmental effects and biotic response, and cratering chronology. Naturally, advancing our understanding of impact phenomena requires a multidisciplinary approach, which includes (but it is not limited to) observations of craters, strewn field or airbursts, numerical modelling, laboratory experiments, geologic and structural mapping, remote sensing, as well as petrographic and geochemical analysis of impact products.
We welcome presentations across this broad range of studies about natural or artificial impact collision phenomena on planetary and small bodies. In particular, we encourage work that bridges the gap between the investigative methods employed in studying planetary impact processes at all scales.

TP5 – Astrobiology
Astrobiology is the study of whether present or past life exists elsewhere in the universe. To understand how life can begin in space, it is essential to know what organic compounds were likely available, and how they interacted with the planetary environment. This session seeks papers that offer existing/novel theoretical models or computational works that address the chemical and environmental conditions relevant to astrobiology on terrestrial planets/moons or ocean worlds, along with other theoretical, experimental, and observational works related to the emergence and development of Life in the Universe. This includes work related to prebiotic chemistry, the chemistry of early life, the biogeochemistry of life’s interaction with its environment, chemistry associated with biosignatures and their false positives, and chemistry pertinent to conditions that could possibly harbor life (e.g. Titan, Enceladus, Europa, TRAPPIST-1, habitable exoplanets, etc.). Understanding how the planetary environment has influenced the evolution of life and how biological processes have changed the environment is an essential part of any study of the origin and search for signs of life. Earth analogues experiments/instruments test and/or simulation campaigns and limits of life studies are included as well as one of the main topics of this session. Major Space Agencies identified planetary habitability and the search for evidence of life as a key component of their scientific missions in the next two decades. The development of instrumentation and technology to support the search for complex organic molecules/sings of life/biosignatures and the endurance of life in space environments is critical to define unambiguous approaches to life detection over a broad range of planetary environments.

TP6 – Earth – a laboratory to prepare space exploration
Study of terrestrial analogue extreme environments is essential to prepare space researchers and coming missions, including (field) testing and improving technologies and prototype instrumentation, and space mission concepts. In addition it provides critical information to train astronauts for surface extra-vehicular activity, to develop science-driven robotic and human exploration missions. Planetary exploration and research in astrobiology have to rely on experiments and detection strategies that can be tested and proved on Earth.
We welcome abstracts on different surface planetary processes, geochemical and astrobiological investigations using field analogues and laboratory simulation studies, field methods and sampling techniques. We also encourage abstracts focused on studies testing robotic missions and research regarding training crewed exploration missions and strategies, and testing exploration technology applications. Furthermore, we welcome abstracts outlining the use of the analogue field sites in engaging the public, as well as space agencies, the media, and educators. Terrestrial analogues are absolutely essential during all steps of a planetary mission, from the planning and definition phase, to the development of the space hardware and instrumentation, in situ operations and for understanding the limits of potential extraterrestrial microbial habitability and testing the reliability of biosignatures in the sedimentary record. Terrestrial analogues are also useful for training educators and developing public outreach activities.

TP7 – Cruise and planetary flybys investigations through space missions
In the latest years, many spacecraft missions operating in the Solar System are collecting data from the many regions of the heliosphere, sensibly increasing the scientific return of each mission, and providing additional opportunities for synergistic data acquisitions from environments and conditions that are different from each mission’s original baseline science operation plan.
In addition, coordinated observations among different spacecraft is allowing to perform valuable investigations of the heliosphere from different point of view at the same time; thereby addressing many aspects of plasma processes related to the Sun, as well as the interactions of the solar wind and radiation with the planetary environments.
A bright example is the Venus atmosphere and magnetosphere investigations recently performed by BepiColombo, Parker Solar Probe and Solar Orbiter during their flybys around the planet, as well as their coordination with Akatsuki spacecraft orbiting around Venus itself, and with other spacecraft during their cruise measurements and with space and Earth-based telescope observations made jointly.
In this session, we welcome contributions to any kind of planetary and Solar System investigations made by space missions during their cruise and flybys operations. They may include the present flybys to Earth and Venus by BepiColombo, Solar Orbiter and Parker Solar Probe, but also future flybys investigations that will be made by future missions (i.e. JUICE); lessons learnt from past flybys to other planets such as the Rosetta flyby to Mars, the Earth and Venus flybys from Cassini or the legacy of the flybys to the Giant planets made by the Voyager missions.

TP8 – Planetary space weather and space weathering on airless bodies
The surfaces of air-less celestial bodies are directly exposed to the environmental radiation, ions, and micrometeoroids. The result of these interactions is an alteration of the surface structure and chemical composition, generally referred to as space weathering. At the same time, these interactions release surface material that refills the surface-bounded exosphere and, directly or indirectly, is a source of planetary ions in the environment. The study of the planetary response to variable external conditions is the broad meaning of planetary space weather.
Over the next decade, the BepiColombo mission to Mercury and JUICE mission to Jupiter’s system, together with the Moon space exploration program, will offer unprecedented opportunities to investigate the interaction processes at airless bodies.
In the present session, we welcome observation-driven, theoretical, and experimental studies
• on all the air-less bodies interacting with solar wind (like Mercury, Moon and asteroids) or with magnetospheric ions (outer planets icy moons);
• on micrometeoroid gardening and impact vaporization effects onto the surface and onto the exosphere;
• on the effects of other agents like photons, electrons, and high-energy particles;
• on laboratory experiments for investigating surface release processes and surface modifications.
• on spectral measurements of various planetary analogous undergone space weathering processes.

TP10 – Ionospheres of unmagnetized or weakly magnetized bodies
Ionospheres are a fundamental part of planetary and cometary atmospheres that are formed by solar radiation and are affected by a myriad of different processes, such as space weather activity or neutral atmosphere variations. Moreover, ionospheres play an important role in controlling the dynamics of the system, as they are the link between the neutral atmosphere, exosphere and surrounding plasma environments (e.g. the solar wind for Mars, Venus, Pluto and comets, and the Kronian magnetosphere for Titan). Understanding how each unmagnetized body reacts to all these factors is a key in comparative aeronomy because although a priori all of them have a general similar behaviour, they also have scientifically important differences caused by their different natures.
This session focuses on the ionospheres of Mars, Venus, Pluto, Titan, and comets, and solicits abstracts concerning remote and in situ data analysis, modelling studies, instrumentation and mission concepts. Topics may include, but are not limited to, day and night side ionospheric variability, sources and influences of ionization, ion-neutral coupling, current systems, comparative ionospheric studies, and solar wind-ionosphere interactions and responses of the ionized and neutral regimes to transient space weather events. Abstracts on general plasma and escape processes are also welcome.
Convener: Beatriz Sanchez-Cano | Co-conveners: Niklas Edberg, Xiaohua Fang, Christopher Fowler, Francisco González-Galindo, Yingjuan Ma
TP12 – Atmospheres and Exospheres of Terrestrial Bodies
Space missions have provided a wealth of data on the atmospheres and aeronomy of rocky planets and moons, from the lower layers up to the external envelopes in direct contact with the solar wind. A recent emerging finding is evidence that the atmosphere behaves as a single coherent system with complex coupling between layers.
This session solicits contributions that investigate processes at work (chemistry, energetics, dynamics, electricity, escape etc…) on the terrestrial bodies of the Solar System and includes studies of the coupling between the lower/middle and upper atmospheres. Contributions based on analysis of recent spacecraft and ground-based
observations, comparative planetology studies, numerical modelling and relevant laboratory investigations are particularly welcome. The session will consist of invited and contributed oral talks as well as posters.
Convener: Anni Määttänen | Co-conveners: Francisco González-Galindo, Dmitrij Titov
TP14 – Mercury Science and Observations
Understanding the formation, evolution, composition, the interior structure and the environment of Mercury is a primary goal of the ESA/JAXA BepiColombo mission and of many theoretical, observational, and experimental studies. NASA’s MESSENGER spacecraft provided many new insights and surprising results regarding these goals. However, the mission also raised many new questions that will be addressed by ESA/JAXA BepiColombo that has been successfully launched in October 2018. This session welcomes contributions addressing the planet’s geology, surface composition, geodesy, interior structure, laboratory measurements, ground-based observations, exosphere, magnetosphere, gravity and magnetic fields and all those work related to the investigation of this terrestrial planet.
A second focus lies on plans for new mission ideas to Mercury including Mercury landing modules.

TP15 – Venus Science and Exploration
The session welcomes presentations on all aspects of the Venus system including interior, surface, atmosphere and ionosphere. We welcome presentations based on past or current observations, theory and modelling, as well as presentations related to future instrumentation, orbiter & in-situ mission concepts.

TP18 – Fluid Circulation, Fluid-Rock Interactions, and Cryosphere on Mars
This session welcomes presentations about aqueous/ice migrations and fluid flows on the surface and subsurface of Mars. Fluid flows are central in fields such as volcano-tectonic, diagenesis, deep-biosphere and water/ice cycles. Accordingly, participants are encouraged to apply for this session with contributions concerning: 1) fluid migration mechanisms, products and effects (e.g. fluvial lacustrine environments, mud volcanism, hydrothermalism) and 2) volatile evolution from erosion to deposition and diagenesis. Experimental and numerical modeling of fluid circulation processes and water-rock interaction are also welcome.

TP21 – The emergence of Life in our Solar System and Beyond
This session seeks papers on the biological, physicochemical, astrophysical, and paleontological studies of the living-matter origination problem, mechanism, conditions necessary and sufficient for living-matter origination and development on the Earth and other celestial objects; promising celestial objects for the living-matter occurrence, and other experimental, theoretical, and observational works related to the emergence and development of Life in our Solar System and beyond are welcomed.
This includes work related to theme of the Origins of Life to study interstellar chemistry, meteorites and comets chemistry as well as the chemistry of planets. A central issue in the research on the emergence of life is the paradoxical role of water in pre-biotic chemistry. Infact,on the one hand, water is essential for all known life, on the other hand it is highly destructive for key biomolecules such as nucleic and polypeptides.
A truly interdisciplinary approach is needed to delve into the core of the issue of emergence of life, because in addition to physics and chemistry it is also need to deploy a number of other sciences. We rely on contribution caming from mathematical or philosophical perspectives not only on astrobiology moreover we think that a part of the answers may lie in scientists who working on cancer research, genetics, space exploration paleontology who are not necessarily involved in this field. I argue that synthetic biology field, challenging most accepted definitions of life too, might also shed some novel and interesting perspectives on one of the most puzzling unanswered questions of science.

EXO1 – Zooming In On Planet Formation
The inner regions of planet forming disks surrounding young stars are key to our understanding of the formation of rocky, Earth-like planets and super-Earths. We know from exoplanet surveys that such planets are abundantly present around low mass stars. Rocky planets are essential ingredients in the quest for life outside the solar system. Understanding their properties and formation history is key to our efforts to put the solar system in perspective.
Investigations of the outer regions of the accretion disk provide us with information on the distribution of volatile material and ices in planetary systems, and studies on disk properties, on evolved cold, gaseous or sub-Neptune planets, as well as migration studies of planets leading to various different system architectures (e.g. to hot Jupiters close to their host star) help us to better understand the evolution of our own solar system.
We invite abstracts from different disciplines working on planet formation, including for example observations of planet forming disks, recent or on-going exoplanet surveys, theoretical and computational models, as well as comparative studies using solar system data from exploration missions, meteorite analysis and remote sensing.

MITM7 – Developments in the detection and characterization of planetary atmospheres
The study of planetary and exoplanetary atmospheres involves a wide range of techniques and disciplines which provide crucial information about their vertical layering, their dynamics and chemistry, the role of condensable species in their meteorology. It is also a key contribution to the understanding of planet and moon climates and of their potential as habitable worlds, particularly in the case of exoplanets. The techniques involved in such investigations include, among other, ground-based telescopic observations, computer simulations and numerical models, and direct spacecraft observations (orbiters, landers, entry probes).
We welcome presentations reviewing the current state-of-the-art techniques for the observation and investigation of (exo-)planetary atmospheres (composition, chemistry, dynamics), discussing the technical challenges and recent developments, and the implications for the potential habitability of exoplanet candidates.

OPS5 – Aerosols and clouds in planetary atmospheres
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.
