Electromagnetic dissociation and space radiation [PDF]
Acta Astronautica, 2007 Relativistic nucleus-nucleus reactions occur mainly through the Strong or Electromagnetic (EM) interactions. Transport codes often neglect the latter. This work shows the importance of including EM interactions for space radiation applications.

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

Karymsky volcano eruptive plume properties based on MISR multi-angle imagery and the volcanological implications [PDF]
Atmospheric Chemistry and Physics, 2018 Space-based operational instruments are in unique positions to monitor volcanic activity globally, especially in remote locations or where suborbital observing conditions are hazardous.

Deep Space Observations of Terrestrial Glitter
Earth and Space Science, 2021 Deep space climate observatory (DSCOVR) spacecraft drifts about the Lagrangian point ≈1.4–1.6 × 106 km from Earth, where its Earth polychromatic imaging camera (EPIC) observes the sun‐lit face of the Earth every 1 to 2 hours.

Postsynaptic density radiation signature following space irradiation
Frontiers 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
Frontiers 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.

Frontiers in Astronomy and Space Sciences, 2023 Introduction: Missions beyond low Earth orbit (LEO) will expose astronauts to ionizing radiation (IR) in the form of solar energetic particles (SEP) and galactic cosmic rays (GCR) including high atomic number and energy (HZE) nuclei. The gastrointestinal

Limitations in Predicting the Space Radiation Health Risk for Exploration Astronauts [PDF]
, 2018 Despite years of research, understanding of the space radiation environment and the risk it poses to long-duration astronauts remains limited. There is a disparity between research results and observed empirical effects seen in human astronaut crews ...

Study of Modeling Parameters in Determination of TID, DD, and SEE Radiation Damages for Satellite in LEO Orbit Using OMERE Software [PDF]
فصلنامه علوم و فناوری فضایی, 2019 One of the important issues to be considered in the design of space systems is the attention to the difference between the terrestrial and space environment. This issue changes the design and affects all subsystems of space systems.
