Gautam D. Badhwar,M.J. Golightly,A. Konradi,W. Atwell,John Kern,B. Cash,E.V. Benton,A.L. Franks,D. Sanner,R.P. Keegan,L. A. Frigo,Vladislav Petrov,I.V. Tchernykh,Yu. Akatov,Vyacheslav Shurshakov,V.V. Arkhangelsky,V.V. Kushin,N.A. Klyachin,N. Vana,W. Schöner +19 more
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
Cary Zeitlin,T. F. Cleghorn,Francis A. Cucinotta,Premkumar B. Saganti,V. Andersen,Kerry Lee,L. S. Pinsky,W. Atwell,R. Turner,Gautam D. Badhwar +9 more
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
John E. Nealy,F. A. Cucinotta,John W. Wilson,Francis F. Badavi,Ts.P. Dachev,Borislav Tomov,S. A. Walker,G. De Angelis,G. De Angelis,S. R. Blattnig,W. Atwell +10 more
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.
