With the rapid growth in the exploitation of space for applications serving society, and ambitious plans for scientific missions, proper evaluation of the effects of the space environment on future space infrastructures is crucial for all aspects of this evolution. Evaluations of space weather and space environmental climate for these missions face numerous difficult challenges. Effects that have to be coped with include solar array degradation, dose effects on electronics and humans, electrostatic charging and discharging, and single event effects.
Solar Energetic Particle (SEP) events are an important transient component of the space weather. It remains very difficult to predict the occurrence, magnitude and timing of SEP events at Earth based on observations of different types of solar precursors and eruptive events (solar flares, coronal mass ejections, etc.), and current understanding of physical solar processes, particle acceleration and transport. Similarly, the ability to predict time variations of the Earth’s Radiation Belts (RBs) is lacking. The belts respond to solar events via geomagnetic storms, but also reflect changes to the source and loss processes at low altitude via the atmosphere.

This session will focus on SEP and RB phenomena as sources of space environment hazards. For both SEP and RB environments, contributions discussing the following are solicited: end user experiences of effects and consequent needs; data processing and statistical analysis/modelling; and physics based modelling serving end user needs. These contributions can address both space weather and climatological (long-term statistical) aspects. The organisers encourage discussion of the needs of mega-constellations, missions with “electric orbit raising” and future human exploration such as the “deep space gateway”.
