Design considerations for the use of laser-plasma accelerators for advanced space radiation studies [PDF]

open access: yes, 2012
We present design considerations for the use of laser-plasma accelerators for mimicking space radiation and testing space-grade electronics. This novel application takes advantage of the inherent ability of laser-plasma accelerators to produce particle ...

The Effects of Space Radiation and Microgravity on Ocular Structures [PDF]

open access: yesTurk J Ophthalmol, 2022
Long-term exposure to microgravity and space radiation leads to physiological and pathological changes in human biology. Pathological neuro-ocular changes are collected under the name spaceflight-associated neuro-ocular syndrome.

Global top-down smoke-aerosol emissions estimation using satellite fire radiative power measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Fire emissions estimates have long been based on bottom-up approaches that are not only complex, but also fraught with compounding uncertainties. We present the development of a global gridded (1° × 1°) emission coefficients (Ce) product for smoke total ...

Postsynaptic density radiation signature following space irradiation

open access: yesFrontiers in Physiology, 2023
Introduction: The response of the brain to space radiation is an important concern for astronauts during space missions. Therefore, we assessed the response of the brain to 28Si ion irradiation (600 MeV/n), a heavy ion present in the space environment ...

Evaluation of deep space exploration risks and mitigations against radiation and microgravity

open access: yesFrontiers in Nuclear Medicine, 2023
Ionizing radiation and microgravity are two considerable health risks encountered during deep space exploration. Both have deleterious effects on the human body.
