Programme group scientific officers: Stephen J. Mojzsis, Stephanie C. Werner, Sarah Rugheimer

Evolutionary pathways of terrestrial planets: Interior/exterior coupling, feedbacks and interactions.

Terrestrial planets are complex systems. Their evolution is dependent on a wide array of different mechanisms and how they interact together. Earth - as the definitive 'terrestrial planet' - is different from the others and we need to have a deeper understanding of why via comparative planetology. The aim of this session is to emphasize the importance of coupling between different layers of the terrestrial planets and feedback processes. 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, with special emphasis on comparative planetology. Both solar system bodies and exoplanets studies are covered. Targeted disciplines include mantle dynamics, planetary structure and composition, tectonic regimes, geomagnetism, volcanism, surface interaction/erosion, atmospheric sciences, volatile cycling, climate and habitability.

Machine Learning in Planetary Sciences and Heliophysics

shouts out for new data analysis strategies. There is a need for frameworks that can rapidly and intelligently extract information from these data sets in a manner useful for scientific analysis. The community is starting to respond to this need. Machine learning, with all of its different facets, provides a viable playground for tackling a wide range of research questions in planetary and heliospheric physics.

We encourage submissions dealing with machine learning approaches of all levels in planetary sciences and heliophysics. The aim of this session is to provide an overview of the current efforts to integrate machine learning technologies into data driven space research, to highlight state-of-the art developments and to generate a wider discussion on further possible applications of machine learning.

Carbon transformation and mobility during planetary geochemical cycling

Earth’s habitability depends on the stable presence of different forms and redox states of carbon at its surface, which is facilitated by the active cycling of mobile carbon between different reservoirs. The past decade saw significant advancements in estimating carbon fluxes among Earth’s reservoirs. Nevertheless, many questions remain about the mechanisms and controlling factors of the transformations between solid carbon — carbonate, organic matter, graphite, diamond, SiC — and mobile carbon in aqueous fluids, gases, and melts in the Earth’s crust and mantle. How do redox gradients, chemical (dis)equilibrium, heterogeneous fluid flow, variable rock and fluid compositions, thermal and chemical gradients, and deformation influence carbon speciation and mobility? What insights on these environmental parameters can we get from studies of carbon-bearing rocks, fluids and melts? These questions are essential to understand if a reactive system acts as a carbon sink —for instance, through mineral carbonation— or a source due to dissolution or melting.
We invite contributions of experimental, modelling and natural case studies related to carbon transformation and mobility from shallow weathering/hydrothermal environments to high-pressure conditions in Earth as well as other planetary bodies.

Sharing numerical and observation based models across Earth and planetary magnetic field studies

Understanding the processes that generate the magnetic fields of Earth and other bodies is vital for explaining planetary evolution, past behaviour of the field and predicting future changes. Such understanding can only arise by combining observations to generate models of the fields and carefully comparing model properties with numerical simulations of the dynamo process. Key advances from this approach include linking observations and physics of rapid field changes, asymmetries in growth and decay; establishing geographic biases in paleosecular variations; and the potential for improved understanding of core-mantle interactions. Challenges arise from differences in documenting models both across and within the specific disciplinary groups. Observations and simulations are necessarily documented in very different ways so that discipline researchers can assess and reproduce the work. However, this hampers interdisciplinary links where observational and simulation data are combined/compared/contrasted. This session invites contributions from researchers in field models based on geo/paleo/rock magnetism and numerical/experimental modellers of planetary cores. Our aim is to cross discipline-specific boundaries and discuss the potential for community-wide efforts to share data and models driving a dialog that enables cross-disciplinary data-sharing through standardized formats allowing combined approaches to link modern, paleo and dynamo studies.

Generation of plate tectonics from mantle dynamics | Virtual PICO

Understanding the generation of plate tectonics from mantle convection is one of the long-standing “grand challenges” of geodynamics. While much progress has been made, a systematic understanding ranging from the grain scale to the global scale is lacking. Key is to understand processes that cause weakening and localisation at subduction zones, transform boundaries and divergent boundaries - processes including grain-size reduction, shear heating, compositional effects (e.g. hydration/dehydration, weak sediment advection) and anisotropy development. This session aims to combine interdisciplinary approaches (geodynamics, mineral physics, geology, …) to understanding these processes and how they manifest from the early Earth to the present day Earth and to exoplanets.

PS2 – Space weather and space weathering: Active and passive processes, observations and records

Programme group scientific officers: Ingrid Mann, Stephen J. Mojzsis

Exploring the stellar radiation and particle environment and its impact on (exo)planetary habitability

Currently, cool stars are prime targets for detecting habitable rocky (Earth-like) exoplanets. Next-generation missions like the JWST, ELT, and LIFE could, in principle, detect atmospheric biosignatures (indicators for life) in Earth-like atmospheres for the first time. Therefore, theoretical background studies addressing the particle- and radiation environment of cool stars and their imprint on exoplanetary habitability are mandatory. The conditions of stellar space weather vary with the presence of strong stellar winds, extreme stellar particle events, and coronal mass ejections (CMEs). These variations may lead to atmospheric erosion and could induce changes in the atmospheric composition via photochemical effects and changes in the atmospheric secondary particle environment. Subsequently, these effects may destroy atmospheric biosignatures and could prevent the creation and development of life.

Detailed knowledge of cool-star astrospheres and the astrospheric particle- and radiation environment in the form of (E)UV, X-Rays, and stellar particles is mandatory to understand planetary habitability. Thus, it is time to extend our knowledge to extrasolar planetary systems with potentially habitable exoplanets in the HZs of G-, K- and M-stars.

By bringing together scientists from all research fields related to solar, astrophysical, and (exo)planetary sciences, this session aims to stimulate discussions on how individual disciplines can share their knowledge and benefit from each other.

We solicit contributions related to:

* (Modeling) stellar astrospheres and the corresponding energy-dependent CR flux
* (Modeling) the environment of close-in exoplanets of cool stars
* (Modeling) stellar CMEs
* Solar scaling laws and their application for cool stars
* The imprint of the stellar particle and radiation field on exoplanetary magnetic fields and atmospheres
* Atmospheric (modeling) studies of climate and (biosignature) photochemistry and the influence of stellar activity

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. These objects 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.

Cosmic rays across scales and disciplines: the new frontier in environmental research

Cosmic rays carry information about space and solar activity, and, once near the Earth, they produce isotopes, influence genetic information, and are extraordinarily sensitive to water. Given the vast spectrum of interactions of cosmic rays with matter in different parts of the Earth and other planets, cosmic-ray research ranges from studies of the solar system to the history of the Earth, and from health and security issues to hydrology and climate change.
Although research on cosmic-ray particles is connected to a variety of disciplines and applications, they all share similar questions and problems regarding the physics of detection, modeling, and the influence of environmental factors.

The session brings together scientists from all fields of research that are related to monitoring and modeling of cosmogenic radiation. It will allow sharing of expertise amongst international researchers as well as showcase recent advancements in their field. The session aims to stimulate discussions about how individual disciplines can share their knowledge and benefit from each other.

We solicit contributions related but not limited to:
- Health, security, and radiation protection: cosmic-ray dosimetry on Earth and its dependence on environmental and atmospheric factors
- Planetary space science: satellite and ground-based neutron and gamma-ray sensors to detect water and soil constituents
- Neutron and Muon monitors: detection of high-energy cosmic-ray variations and its dependence on local, atmospheric, and magnetospheric factors
- Hydrology and climate change: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack, and vegetation
- Cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in archaeology or glaciology for dating of ice and measuring ablation rates; and as a tool for surface exposure dating and measuring rates of surficial geological processes
- Detector design: technological advancements for the detection of cosmic rays
- Cosmic-ray modeling: advances in modeling of the cosmic-ray propagation through the magnetosphere and atmosphere, and their response to the Earth's surface
- Impact modeling: How can cosmic-ray monitoring support environmental models, weather and climate forecasting, irrigation management, and the assessment of natural hazards

Energetic Particles: From the Sun to their Impacts at Earth and Other Planets

The heliosphere is permeated with energetic particles of different compositions, energy spectra and origins. Two major populations of these particles are galactic cosmic rays (GCRs), which originate from outside of the heliosphere and are constantly detected at Earth, and solar energetic particles (SEPs) which are accelerated at/near the Sun during solar flares or by shock fronts associated with the transit of coronal mass ejections. Enhancements in energetic particle fluxes at Earth pose a hazard to humans and technology in space and at high altitudes. Within the magnetosphere, energetic particles are present in the radiation belts, and particle precipitation is responsible for the aurora and for hazards to satellites. Energetic particles have also been shown to cause changes is the chemistry of the middle and upper atmosphere, thermodynamic effects in the upper troposphere and lower stratosphere region, and can influence components of the global electric circuit. This session will aim to address the transport of energetic particles through the heliosphere, their detection at Earth and the effects they have on the terrestrial atmosphere when they arrive. It will bring together scientists from several fields of research in what is now very much an interdisciplinary area. The session will allow sharing of expertise amongst international researchers as well as showcase the recent advances being made in this field, which demonstrate the importance of the study of these energetic particle populations.

Inner-magnetosphere Interactions and Coupling

The Earth's inner magnetosphere contains different charged particle populations, such as the Van Allen radiation belts, ring current particles, and plasmaspheric particles. Their energy range varies from eV to several MeV, and the interplay among the charged particles provides feedback mechanisms that couple all those populations together. Ring current particles can generate various waves, for example, EMIC waves and chorus waves, which play important roles in the dynamic evolution of the radiation belts through wave-particle interactions. Ring current electrons can be accelerated to relativistic radiation belt electrons. The plasmaspheric medium can also affect these processes. In addition, precipitation of ring current and radiation belt particles will influence the ionosphere, while up-flows of ionospheric particles can affect dynamics in the inner magnetosphere. Understanding these coupling processes is crucial.

While the dynamics of outer planets’ magnetospheres are driven by a unique combination of internal coupling processes, these systems have several fascinating similarities which make comparative studies particularly interesting. We invite a broad range of theoretical, modeling, and observational studies focusing on the dynamics of the inner magnetosphere of the Earth and outer planets, including the coupling of the inner magnetosphere and ionosphere and coupling between the solar wind disturbances and various magnetospheric processes. Contributions from all relevant fields, including theoretical studies, numerical modeling, observations from satellite and ground-based missions are welcome. In particular, we encourage presentations using data from MMS, THEMIS, Van Allen Probes, Arase (ERG), Cluster, cube-sat missions, Juno, SuperDARN, magnetometer, optical imagers, IS-radars, and ground-based VLF measurements.

PS3 – The early solar system (in partnership with GMPV and GD)

Programme group scientific officers: Stephen J. Mojzsis, Stephanie C. Werner, Patricia L. Clay

Formation and Chronology of Early Solar Systems

Meteorites and their components, such as pre-solar grains, refractory inclusions and chondrules, contain critical information on the accretion and evolution of the Solar System. Bulk meteorites reveal the existence of two early-formed isotopic reservoirs. This isotopic dichotomy between the non-carbonaceous (NC) and carbonaceous (CC) reservoirs provides a framework to explore the evolution of the solar protoplanetary disk. Using early-formed materials we can address key questions such as the nucleosynthetic heritage of the Solar System, thermal and mixing processes, and the accretion and compositional histories of planetesimals and planets. At the same time, astronomical observations of extrasolar planetary systems start to provide analogue constraints on the evolution of extrasolar accretion disks. This session will provide space to discuss constraints on the formation and evolution of the solar and extrasolar protoplanetary disks and their components to better constrain the timescales and mechanisms of planetary formation. We welcome contributions from different fields of expertise, including studies of nucleosynthetic isotope variations in Solar System materials, long- and short-lived chronometers applied to meteorites, geophysical modelling of planetesimals, and astronomical observations and models of protoplanetary disk evolution and dynamics.

Volatiles in the early Solar System: source(s), delivery, and influence

Volatile elements (such as H, C, N noble gases and the halogens) play an important role in the evolution of Solar System objects. Tracing the origin and evolution of volatile elements in the Solar System is therefore crucial to our understanding of the origin of water and planetary atmospheres, the physical and chemical processing of Solar System bodies, and the formation of habitable environments. Investigation of meteorites, interplanetary dust particles (IDPs) and the study of samples returned from missions all offer opportunities to further our understanding of the origin and character of volatiles. We invite contributions that aim to understand aspects of: (i) the origin and subsequent processing of volatiles in early Solar System materials and small bodies, (ii) the delivery of volatiles to planetary bodies, and (iii) the role of volatiles in the chemical evolution of planets. This includes, but is not limited to, geochemical analyses of meteorites and return samples, experimental samples, and the modelling of the behaviour of volatiles in planetary bodies. We welcome contributions on objects from the inner (e.g., the Moon and Mars) and outer (e.g., comets) Solar System and their precursors.

Coupled planet formation and evolution: from accretion to long-term evolution

Planetary accretion, giant collisions, core formation, magma-ocean crystallization and other important processes during the early days of the solar system set the stage for the long-term evolution of terrestrial planets. These early processes can happen simultaneously or in recurring stages, and are ultimately followed by progressive crustal growth, long-term mantle mixing/differentiation, core-mantle interaction, as well as inner-core crystallization. Indeed, the coupled early and long-term evolution shapes the present-day structure and thermal state of planetary interiors. We seek to gain a better understanding of the formation and evolution of terrestrial bodies by bringing together studies from geophysics, geodynamics, mineral physics, geochemistry, and petrology.
This session welcomes contributions focused on data analysis, modeling and experimental work that address the formation and evolution of terrestrial planets and moons in the Solar System, and around other stars.

Paving the Way to the Decade of Venus

In June 2021, NASA and ESA selected a fleet of three international missions to planet Venus. 28 years since the Magellan orbital radar mapping mission, and 37 years since the last Venera/VeGa landing, Venus remains our enigmatic neighbour. Shrouded by its dense atmosphere, the surface is only studied from space at radar frequencies and in a limited number of near-infrared spectral windows. Many significant questions remain on the current state of Venus, suggesting major gaps in our understanding of how our nearest planet's evolutionary pathway diverged from Earth's. Did Venus ever have an ocean, how and when did greenhouse conditions develop, and to what degree do volcanic eruptions still affect the surface and atmosphere today? Comparing the interior, surface and atmosphere evolution of Earth and Venus is essential to understanding what processes have shaped our own planet. This is particularly relevant in a decade where we expect hundreds of Earth- & Venus-size exoplanets to be discovered. The session will also address how these new missions will better understand Venus’ early evolution and past and present habitability.

Dynamic, structural, and compositional evolution of Earth and rocky planets

The present state of Earth and other rocky planets are an expression of dynamical and chemical processes occurring throughout their history. The rock-record, through geochemistry and magnetism, is used to interrogate changes in the tectono-thermal regime of Earth’s interior through time, while seismic imaging and gravity data, for instance, provide a snapshot of processes occurring in the contemporary mantle, crust and core. These classes of observations may be linked through geodynamic models, whose accuracy is underpinned by the physical properties (e.g., viscosity and density) of its constituent phases (minerals, melts and fluids). Information on the fundamental thermodynamic and physical behaviour of phases is subject to constant advance via experimental and ab-initio techniques.

This session aims to provide a holistic view of the dynamics, structure and composition of Earth, from core to atmosphere, and their evolution through time. We welcome contributions that address questions surrounding Earth’s major geological transformations and initial conditions that include, but are not limited to, plate tectonic behaviour, magma ocean dynamics and planetary oxidation. Studies using a multidisciplinary approach are particularly encouraged.

Earth's and planetary cores: structure, dynamics and evolution.

Understanding the structures and dynamics of the core of a planet is essential to construct a global geochemical and geodynamical model, it has implication on its thermal, compositional and orbital evolution.

Remote sensing of planets interior from space and ground based observations is entering a new era with perspectives in constraining their core structures and dynamics. Meanwhile, increasingly accurate seismic data provides unprecedented images of the Earth's deep interior. Unraveling planetary cores structures and dynamics requires a synergy between many fields of expertise, such as mineral physics, geochemistry, seismology, fluid mechanics or geomagnetism.

This session welcomes contributions from all these disciplines following theoretical, numerical or experimental approaches , with the aim to proceed towards an integrated, self-consistent picture of core structure, dynamics and history.

Melts and volatiles in Earth and planetary interiors across scales and disciplines

The global-scale cycling of volatile species (hydrogen, carbon, nitrogen, sulphur etc.) controls the mass, composition and state of the outermost layer of terrestrial planets over time, thereby controlling their habitability. These planetary volatile cycles involve the atmosphere, hydrosphere, crust, mantle and perhaps even core. On geological timescales, they are controlled by plate tectonics and/or mantle convection and by magmatism. Indeed, mantle melting is a key process that partitions (volatile) elements between the various planetary reservoirs, which brings the geochemists and petrologists expertise to the forefront of this topic. On Earth, major volatile cycles are balanced to first order through ingassing and outgassing, mainly occurring at subduction zones, and major sites of volcanism (i.e., mid-ocean ridges and hotspots), respectively. In planetary interiors, volatiles are partitioned into the existing minerals, or stabilize minor phases such as diamond or various hydrous phases in the mantle and crust, something that directly influences the spatial distribution of melt formation. Conversely, melt transport induces volatile exchanges between planetary reservoirs and favors outgassing. Understanding the complex dynamics of melt/fluid segregation or accumulation is thus crucial for understanding global-scale volatile/material cycling. Further, melt retention as well as volatile content and speciation strongly and non-linearly affect rock properties such as viscosity, modal mineralogy, melting behaviour, oxidation state, seismic velocity and attenuation, electrical conductivity and density, which put recent advances in geophysics under the spotlight for detecting and characterising these processes.
In this session, we invite contributions from all disciplines of the Earth and Planetary Sciences, with focus on volatile cycling and reservoir exchanges through fluid/melt percolation, magmatism from regional to global scales, effects of volatiles on material properties, melt stabilisation, related observations or processes. Experimental, observational, modelling and integrated multidisciplinary studies are highly welcome.

PS6 – (Exo)terrestrial-type planets: Endogenic and exogenic processes

Programme group scientific officers: Stephen J. Mojzsis, Daniel Kitzmann, Sarah Rugheimer

Interior-Surface-Atmosphere Volatile Exchange on Earth and Other Terrestrial (Exo)planets

The surfaces of terrestrial planets are central to the exchange of volatiles (e.g., C, H, O, S) between the interior and the atmosphere. Distribution of volatiles across reservoirs and processes controlling the volatile exchange rates regulate planetary climate and habitability. The carbonate-silicate cycle on Earth, for example, has provided a relatively stable climate on Earth for billions of years by regulating the amount of the key greenhouse gas, CO2, in the atmosphere. In addition to carbon, other volatile elements such as hydrogen, oxygen and sulfur are also cycled between the atmosphere and the interior, with their cycling pathways and efficiency dependent on numerous factors including the presence of liquid water and the tectonic mode.

The aim of this session is to bring together numerical, experimental and observational expertise from Earth and planetary sciences to advance the understanding of volatile exchange on Earth as well as terrestrial (exo)planets. Several important questions arise. Is plate tectonics a necessity to sustain volatile cycling? How do surface rock types (subaerial or submarine) influence the atmospheric composition? What can past climate states of Earth, Venus and Mars tell us about volatile exchange mechanisms and about the climate of exoplanets? What is the role of condensable and non-condensable gases in the preservation of temperate climates? We welcome a wide range of contributions from planetary sciences, atmosphere sciences, climatology, geochemistry, hydrology, petrology, geodynamics, and mineral physics on topics including but not limited to volatile cycles, surface lithology, tectonic regimes, outgassing, mantle redox states, ridge and arc volcanism, subduction zones, water-rock interactions, weathering, habitable zone, climate science, atmospheric structure and composition.

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 or nanosatellites (like BepiColombo, Juice, Solar Orbiter, Solar Probe, SunRISE, UVSQ-Sat, Inspire-Sat 7) are also welcome.

Life as a Planetary Phenomenon

The biosphere and geology of a planet are intrinsically interlinked. The geological habitat of Earth has driven the origin and evolution of life and biology has dramatically changed the planets surface and mineralogy over the last 4 billion years. In our Solar System, there are a broad range of planets and moons with potential habitable environments, and future missions will aim to determine if these ever had life or have life today. Planets orbiting other stars have different spectral types and metallicities and thus different starting bulk compositions which may impact the origin and evolution of life on those worlds. This session will examine the interplay of biology, and more broadly, habitability, from a planetary perspective.

Early Earth: Dynamics, Geology, Chemistry and Life in the Archean Earth | Virtual PICO

Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time.
In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons.
We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history.

PS11 – The geo in planetary and the planetary in geo: terrestrial analog studies, ground-truthing, training, mission development and testing

Programme group scientific officer: Jessica Flahaut

From the environment of the Earth to the environment of the Solar System

On Earth, we have seen consequential environmental problems in recent years, such as devastating floods, monstrous wildfires, and deadly health crisis. Though humans did not have the intention of affecting the whole planet with industrialization, our activities have shaped the Earth as new studies more confidently demonstrate human activity as one of the major contributing sources to these events.

Concurrently, advancing science and technology is allowing humans to significantly expand their presence beyond Earth with strong commitments by space agencies around the world to increase their efforts. This also raises issues. We have already seen concrete examples, such as defunct objects falling down to Earth. Some issues could arise soon, such as from utilizing lunar resources.

With this background, we invite geoscientists, environmental scientists, planetary scientists, engineers, and policy makers to think about the following question: What have we learned by studying the effect of human activities on Earth at planet scales, and knowing that, how will the advancing space programs impact the state of objects in the Solar System?

Suggested topics include but are not limited to; review of environmental problems on Earth with implications to other planetary bodies; overview of new missions and assessment of their footprints; analog studies; past climate on Earth and other planets; case studies of how geoscientists have hypothesized, designed experiments, measured, and assessed the impact of human activities on Earth. Field-based, remote sensing, experimental, modeling, and theoretical works are welcome.

Analogue Planetary Research and Instruments | Virtual PICO

Analogue planetary research (APR) describes the development and testing
of space exploration strategies including scientific, technical,
operational, social and medical aspects in terrestrial environments
under simulated space or planetary conditions. As such, APR can be
performed in analogue planetary simulation, for example Lunar or Martian
analogue missions, where future crewed or robotic space exploration
missions are simulated and evaluated towards their performance.

With increasing popularity of analogue planetary simulations as
test-beds to develop and test technologies, techniques and operational
procedures for planetary missions in facilities such as HiSeas, MDRS,
LunAres, AATC, MMAARS or similar facilities, this session invites
contributions in the field of analogue planetary research including, but
not limited to:

- data analysis about sites for future exploration
- results and lessons-learned from Lunar / Martian analogue missions
- instruments development for analogue and space research
- field tests for space exploration hardware, software and techniques
- scientific contributions through analogue research
- geological field work during planetary simulations
- future analogue mission concepts
- transferring APR results into actual space exploration missions

Planetary Aeolian Processes and Landforms

Aeolian processes are active on various planetary surfaces throughout the Solar System and yield similar landforms across a wide range of spatial scales despite differences in atmospheric and surface properties. They are typically associated with the movement of sediments driven by an atmospheric flow but can also be controlled by other modes of matter transport such as ice sublimation. The combination of terrestrial and extra-terrestrial experiments and observations provides the opportunities as well as challenges for improving our fundamental theories and numerical models for better understanding of these aeolian environments. Innovations in instrumentation and experimental techniques continue to yield novel insights on Earth, while space missions and remote probes constantly deliver new and surprising evidence from aeolian environments on other planetary bodies. This session welcomes research on all aspects of aeolian processes and landforms, contemporary and ancient, on planetary surfaces across the Solar System.

Planetary Geomorphology

The Planetary Geomorphology session 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.

Novel data, methods and applications in Geomorphometry

Geomorphometry, a science of quantitative land surface analysis, gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation model (DEM) or one of its derivatives. DEMs provide the backbone for many studies in Geo sciences, hydrology, land use planning and management, Earth observation and natural hazards.
One topic of active research concerns compromises between the use of global DEMs at 1-3 arc second, ~30-90 m grid spacing, and local LiDAR/structure from motion (SFM) elevation models at 1 m or finer grid spacing. Point clouds from LiDAR, either ground-based or from airborne vehicles, are a generally accepted reference tool to assess the accuracy of other DEMs. SFM data have a resolution comparable to LiDAR point clouds, but can cost significantly less to acquire for smaller areas. Globally available DEMS include the recently published Copernicus GLO-90 and GLO-30. This session provides an exciting forum to show the potential applications of this new DEM and its improvements over SRTM. We would like to investigate the tradeoff between the employment of the two kinds of data, and applications which can benefit from data at both (local and global) scales.
The improvements in the global DEMs, as well as the increasing availability of much finer resolution LiDAR and SFM DEMs, call for new analytical methods and advanced geo-computation techniques, necessary to cope with diverse application contexts. We aim at investigating new methods of analysis and advanced geo-computation techniques, including high-performance and parallel computing implementations of specific approaches.
Commercial applications of DEM data and of geomorphometric techniques can benefit important business sectors. Besides a proliferation of applications that can tolerate low accuracy geographical data and simple GIS applications, a large base of professionals use high-resolution, high-accuracy elevation data and high-performance GIS processing. We would like to survey and investigate professional, commercial and industrial applications, including software packages, from small enterprises to large companies, to ascertain how academic researchers and industry can work together.

How to build and grow your scientific network

Networking is crucial for scientists of all career stages for collaborations as well as for their personal growth and career pathways. Your scientific network can support you when struggling with everyday academic life, help with making career choices and give feedback on job applications/proposals/papers. Further, having a scientific network can provide new perspectives for your research while leading to interdisciplinary collaborations and new projects.
Building up an initial network can be challenging, especially outside of your research institution. As scientific conferences and social media platforms are evolving, the possibilities of academic networking are also changing. In this short course we will share tips and tricks on how to build, grow and maintain your scientific network. Additionally, panelist will talk about their own personal experiences. In a second part of the short course we will do a networking exercise. This short course is relevant to scientist who are starting to build/grow their network or want to learn more about networking in today’s scientific settings.

How to Find Funding

Finding funds can be challenging in academia, be it during PhD, or after that. A great proposal or just a great idea does not guarantee success, instead, it involves developing skills and exploring the paths which can lead to securing funds. It involves meticulous steps of evolving idea, proposal development, budget generation, and finally finding funding opportunities. In this course, early-career scientists, and faculty members with a wide range of backgrounds will provide guidance both in the research, and financial aspects of the proposal writing. The course is integrated with open Q&A which will provide participants to ask and seek advice from the experts. This course targets a wide range of audience ranging from graduate students to early-career scientists, but anyone with an interest in finding funds could participate

Scientific visualisation: Visualise your data effectively and avoid common pitfalls

Visualisation of scientific data is an integral part of scientific understanding and communication. Scientists have to make decisions about the most effective way to communicate their results everyday. How do we best visualise the data to understand it ourselves? How do we best visualise our results to communicate with others? Common pitfalls can be overcrowding, overcomplicated plot types or inaccessible color schemes. Scientists may also get overwhelmed by the graphics requirements of different publishers, for presentations, posters etc. This short course is designed to help scientists improve their data visualization skills in a way that the research outputs would be more accessible within their own scientific community and reach a wider audience.
Topics discussed include:

- Choosing a plot type – keeping it simple
- Color schemes – which ones to use or not to use
- Creativity vs simplicity – finding the right balance
- Producing your figures – software and tools
- Figure files – publication ready resolutions

This course is organized by the Young Hydrologic Society (YHS), enabling networking and skill enhancement of early career researchers worldwide. Our goal is to help you make your figures more accessible by a wider audience, informative and beautiful. If you feel your graphs are complicated or not intuitive, we welcome you to join this short course.
