Comparative Analysis of Electrodynamic Toroidal Radiation Shielding Configurations
… the protective confines of Earth's atmosphere and magnetosphere, spacecraft are subject to constant bombardment by high-energy charged particles originating from our Sun in the form of Solar Particle Events (SPEs), and from outside the solar system in the form of Galactic Cosmic Rays (GCRs). …

Hypervelocity Impact Analysis of Hybrid Nanocomposite Sensors for Inflatable Space Structures
<p>Future space exploration requires easy-to-transport, and easy-to-build and deploy space habitats. NASA and Bigelow Aerospace have collaborated so that human habitation can be made safe and easy with inflatable space habitats (Litteken, 2017). One of the biggest threats faced by these structures …

Numerical Study of Nutrient Mixing in Trabecular Bone in Microgravity, Disuse and Normogravity
… interstitial fluid flow which stimulates cells and drives nutrient transport within the trabecular network. In microgravity, the absence of mechanical stimulation or loading suppresses convective flow processes, causing diffusion-driven nutrient mixing and renewal, and accelerated bone loss. …

Artificial Intelligence in Human Spaceflight Safety-Critical Systems: A Requirements Framework for AI-Enabled Computer-Based Control Systems
<p>Currently, there is no governing standard that addresses the safe integration of AI into computer-based control systems (CBCS) in human spaceflight. The computer-based control expectations of those safety-critical systems on the International Space Station (ISS) are captured in SSP 50038, …
