Journal ArticleDOI

In-flight radiation measurements on STS-60

TL;DR: The effects of spacecraft attitudes on TEPC dose rates due to the highly anisotropic low-earth orbit proton environment were evaluated and there was good agreement between the U.S. and Russian measurements.
Journal ArticleDOI

Overview of the Martian radiation environment experiment

TL;DR: An overview of the MARIE experiment is provided, including introductory material on space radiation and radiation dosimetry, a description of the detector, model predictions of the radiation environment at Mars, and preliminary dose-rate data obtained at Mars.
Journal ArticleDOI

Cosmic ray hit frequencies in critical sites in the central nervous system.

TL;DR: Critical sites in the CNS: the macula, and an interior brain point were chosen for the calculation of hit frequencies from galactic cosmic rays for a mission to Mars during solar minimum (i.e., at maximum cosmic-ray intensity), and variation of the position of the "target site" within the head plays only a small role in varying hit frequencies.
Journal ArticleDOI

Pre-engineering spaceflight validation of environmental models and the 2005 HZETRN simulation code

TL;DR: The HZETRN code has been identified by NASA for engineering design in the next phase of space exploration highlighting a return to the Moon in preparation for a Mars mission as discussed by the authors.
Journal ArticleDOI

Radiation measurements on the Mir Orbital Station

TL;DR: This paper represents a comprehensive review of Mir Space Station radiation data available from a variety of sources and indicates that there is a factor of about two in dose rate within a given module, and a similar variation from module to module.
