Estimation of Cosmic-Ray-Induced Atmospheric Ionization and Radiation at Commercial Aviation Flight Altitudes

open access: yesApplied Sciences, 2022
The main source of the ionization of the Earth’s atmosphere is the cosmic radiation that depends on solar activity as well as geomagnetic activity. Galactic cosmic rays constitute a permanent radiation background and contribute significantly to the ...

Living With Cosmic Radiation

open access: yesPerspectives of Earth and Space Scientists, 2022
The last two decades of cosmic ray research have been eventful, to say the least. The Voyager spacecraft explored the outer‐most regions of the heliosphere and eventually left our local astrosphere to explore the galaxy.

Considering light-matter interactions in Friedmann equations based on the conformal FLRW metric

open access: yesJournal of Advanced Research, 2023
Introduction: Recent observations indicate that the Universe is not transparent but partially opaque due to absorption of light by ambient cosmic dust. This implies that the current cosmological model valid for the transparent universe must be modified ...

Analysis of the Cosmic Ray Effects on Sentinel-1 SAR Satellite Data

open access: yesAerospace, 2021
Ionizing radiation sources such as Solar Energetic Particles and Galactic Cosmic Radiation may cause unexpected errors in imaging and communication systems of satellites in the Space environment, as reported in the previous literature. In this study, the

Cardiovascular, Lymphatic, and Ocular Health in Space

open access: yesLife, 2022
Life on Earth has evolved continuously under Earth’s 1 G force and the protection of the magnetosphere. Thus, astronauts exhibit maladaptive physiological responses during space travel.
