Cosmic Ray Shielding, Solar Power, and Planetary Habitability

Speaker

 Alaa Salah Afifi | Keplar Space University

Abstract

This research links cosmic ray shielding with the solar power and the solar heliosphere to improve planetary habitability and enable safer exploration. It covers the natural shielding properties of the heliosphere against galactic cosmic rays (GCR) and innovative solar satellite technologies with improved GCR protection and related power delivery to planetary bases. Events from solar eruptions and their propagation consequences on Earth, Mars, and beyond are studied using the Graduated Cylindrical Shell and Wang-Sheeley-Arge-Enlil coronal modeling tools. The results draw attention to the fact that advanced Solar Power Satellites need to be equipped with adequate shielding for mitigation of radiation and long-term energy sustenance. Suggestions for long-term infrastructure on the Moon and Mars need to be proposed to address the problems of dust storms, radiation, and temperature fluctuation extremes.
