--- ST1.4: Outstanding Questions in Heliophysics

Conveners: Rumi Nakamura, Jonathan Rae, Chris Arridge, Lina Hadid, Louise Harra

Activities including the recent ESA Voyage 2050 exercise and the ongoing Heliophysics Decadal Survey in the US have triggered various new ideas on fundamental science themes in the area of solar, solar wind, magnetosphere, ionosphere-thermosphere physics at Earth and different planets, plasma physics around the moon and small body, as well as in the heliospheric boundary region. While the idea of implementation scheme (mission) may differ, there are commonality in the underlying physical processes of interest. Discussing the outstanding problems throughout the heliosphere by bringing the different discipline should bring us new perspective of the broad science area. In this session we invite papers which highlight the outstanding science questions in the different area of space plasma physics throughout the solar system and beyond. Ideas on new observations in space and from ground, new modeling, suggestions on new data analysis schemes are also welcome. We welcome active participation of Early Career Scientists and experts from the broad international heliophysics community


--- ST2.2: Foreshock and magnetosheath transient phenomena and their effects on planetary magnetospheres

Conveners : Savvas Raptis, Heli Hietala, Ferdinand Plaschke, Tomas Karlsson, Christian Mazelle

We look forward to your participation and to a fruitful session in Vienna and online.

Please feel free to forward this e-mail to any colleagues that may find the session relevant.


--- PS6.2: Gas Giant System Exploration in the Solar System and Beyond

Conveners: Joshua Dreyer, Lina Hadid,   J. Hunter Waite

The Gas Giant System Exploration session solicits abstracts on the scientific exploration of the Jovian and Kronian systems with past and current missions (e.g. Juno, Cassini, remote observations), as well as presentations on future exploration missions and concepts (e.g. JUICE). This includes studies on their interiors, atmospheres, ionospheres, and magnetospheres, out to their ring systems and satellites, as well as the respective interactions between these regions. We also explicitly welcome presentations on gas giant exoplanet systems and encourage participation by colleagues more traditionally aligned with astronomy.



--- ST1.11 "Turbulence in space plasmas: from injection to dissipation"

This session ST1.11 is co-organized with NP6

Convener: Olga Alexandrova | Co-conveners: Petr Hellinger, Luca Sorriso-Valvo, Julia Stawarz, Daniel Verscharen

Space and astrophysical plasmas are typically in a turbulent state, exhibiting strong fluctuations of various quantities over a broad range of scales. These fluctuations are non-linearly coupled and this coupling may lead to a transfer of energy (and other quantities such as cross helicity, magnetic helicity) from large to small scales and to dissipation. Turbulent processes are relevant for the heating of the solar wind and the corona, acceleration of energetic particles. Many aspects of the turbulence are not well understood, in particular, the injection and onset of the cascade, the cascade itself, the dissipation mechanisms, as well as the role of specific phenomena such as the magnetic reconnections, shock waves, expansion, and plasma instabilities and their relationship with the turbulent cascade and dissipation.

This session will address these questions through discussion of observational, theoretical, numerical, and laboratory work to understand these processes. This session is relevant to many currently operating missions (e.g., Wind, Cluster, MMS, STEREO, THEMIS, Van Allen Probes, DSCOVR) and in particular for the Solar Orbiter and the Parker Solar Probe.
