Greetings Cosmic Origins Community!

Please join the next early-career talk in the Cosmic Chatter talk series organized by the Cosmic Pathfinders Program.

Cosmic Ray Shielding, Solar Power, and Planetary Habitability

Date

April 15th 4:00 – 5:00pm ET

Meeting connection info can be found here.

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.

Cosmic Pathfinders Program

Transforming the Early-Career Experience in STEM

Cosmic Pathfinders is a student-focused program of online events and in-person gatherings that provides an interface to NASA astrophysics. It is motivated by an immediate need to develop the next generation of the STEM workforce in space-related fields.

Cosmic Pathfinders | Cosmic Pathfinder Chapter Petition

Cosmic Chatter is a series of regularly scheduled, virtual/online colloquia aimed at an early-career science audience. These events will feature prepared remarks from an invited speaker as well as time for discussion and programmatic announcements. Presentation topics will consist of a combination of astrophysics research, as well as professional development topics relevant to this early-career audience. Examples of professional development topics include dealing with imposter syndrome, and how to communicate science effectively. The series will run during a fall term (September – December) and a spring term (January – June). Events will be scheduled monthly. Events will be managed and run by the Program Office, in consultation with student leadership on presenters and topics.
