PS1 – Terrestrial Planets Systems and Comparative Planetology

PS1.1

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.
Review talks on specific topics will be accepted on the basis of invitation by the conveners. Please contact the conveners if you have a topic that may be suitable for a review talk.
The session is open to all branches of terrestrial planets systems geosciences, and is intended as an open forum and discussion between their diverse experts and Earth geoscientists.

Planetary Geomorphology aims to bring together geomorphologists from terrestrial sciences with those who work on other bodies such as Mars, Venus, Mercury, the Moon, icy satellites of the outer solar system, comets, and asteroids. Studies of landscapes on any scale on any solid body are welcome. We particularly encourage those who use Earth analogues (either in the field or laboratory) to present their work. Submissions can include studies on glacial, periglacial, aeolian, volcanic, fluvial, or "undetermined" landforms. We welcome contributions from early-career scientists and geomorphologists who are new to planetary science.

The Mars Science and Exploration Session will address the latest results on the interior, surface, atmosphere and ionosphere of Mars from recent and ongoing Mars missions, as well as the future exploration of the Red Planet. In particular, the session is primarily targeted at: (1) presentations on scientific investigations as well as theoretical models concerning the deep interior and subsurface structure and composition; the surface morphology and composition; the atmospheric composition, dynamics and climate; the ionospheric environment and its interaction with the solar wind; Phobos, water evolution, astrobiology and habitability of Mars; (2) discussions on scientific goals, long-term plans and proposed experiments for future missions to Mars, as well as results obtained from ground-based measurements. The session includes also a small subsession of a community effort for a receiving and curation facility of Mars Sample Return. Both broad solicited talks and contributed presentations will be included in the program.

The InSight mission to Mars landed in Elysium Planitia on November 26. InSight's scientific objective is the study of the Martian interior using two seismometers, a heat flow probe and geodetical measurements. Auxiliary instruments will collect meteorological and magnetic data for at least one Martian year.
This session provides initial results from Mars, status reports of instrument deployment and relevant pre-landing science.

The Sustainable Development Goals (SDGs) (or Global Goals for Sustainable Development) are a collection of 17 global goals set by the United Nations Development Programme.The formal name for the SDGs is: "Transforming our World: the 2030 Agenda for Sustainable Development." That has been shortened to "2030 Agenda." The goals are broad and interdependent, yet each has a separate list of targets to achieve. Achieving all 169 targets would signal accomplishing all 17 goals. The SDGs cover social and economic development issues including poverty, hunger, health, education, global warming, gender equality, water, sanitation, energy, urbanization, environment and social justice.
For this interdisciplinary session, we invite contributions discussing How Earth, Planetary and Space Scientists can address UN Sustainable Development Goals . We shall discuss the relevance of fields of research disciplines covered by EGU, and how they can inform and support society government bodies, and stakeholders for the SDGs.
The session will include invited and contributed oral papers, as well as interactive posters, and panel discussions.

PS1.8

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.

PS1.9

The solar system terrestrial planets, and especially the Earth, provide the best opportunity to learn about the basic physical principles of rocky planets, which can then be applied to the evolution of exoplanets and their atmospheres. Similarly, knowledge of the diversity and properties of exoplanetary systems can provide important information about the formation and evolution of our own solar system. In this session, we will focus on general discussions of exoplanetary science, and especially the application of solar system based knowledge to exoplanets and understanding how the Earth can be understood in the exoplanetary context. Of particular interest are studies of atmospheric evolution due to surface-atmosphere interactions and atmospheric losses to space, as well as interactions between stars and planets. Topics include recent advances in observations of (exo)planets lying in the habitable zone, model studies calculating the habitable zone boundaries, factors affecting habitability including atmospheric processes (e.g. outgassing, escape), high energy particles, remote biosignatures and their spectra, planned missions such as JWST, PLATO, E-ELT, LUVOIR, HABEX and ELF and their impact on our knowledge of exoplanetary habitability.

GD9.1

Terrestrial planets are complex systems. Their evolution is dependent on a wide array of different mechanisms and how they interact together. 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 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 and examine how they can affect planetary evolution. Targeted disciplines include mantle dynamics, planetary structure and composition, tectonic regimes, geomagnetism, volcanism, surface interaction/erosion, atmospheric sciences, volatile cycling, climate and habitability.

GD3.1

Dynamic processes shape the Earth and other planets throughout their history. Processes and lifetimes of magma oceans establish the initial conditions on the development of rocky planets and their early atmospheres. The dynamics of the mantle, the composition and mineral physics shape the present-day observable structure of the Earth's mantle and planetary bodies visible through seismic observations.
This session aims to provide a multidisciplinary view on the processes and structures of the Earth and planets. We welcome contributions that address the structure, dynamics, composition and evolution of their mantle, and their interactions with the outer layers, on temporal scales ranging from the present day to billions of years, and on spatial scales ranging from microscopic mineralogical samples, kilometer-size seismic structures to global planetary models.

GD3.4

Mantle upwellings are an important component of the Earth’s convective system that can cause volcanism and anomalies in surface topography. Upwellings can rise from thermal boundary layers as hot “mantle plumes”. Alternatively, they can be the response to upper-mantle convective flow, subduction, or rifting. Clearly, different mechanisms sustain mantle upwellings of various temperature, vigour and composition, causing characteristic signals that can potentially be imaged using geophysical data, as well as expressed in the geochemistry and petrology of related magmatism.

This session invites contributions that focus on mantle upwellings from geophysics, geochemistry, and modelling perspectives. Our aim is to bring together constraints from multiple disciplines to understand the origin and dynamics of mantle upwellings, as well as their potential to trigger mantle melting, create volcanism, generate ore deposits, and build dynamic topography.
