Technology validation of optical fiber cables for space flight environments
Periodically, commercially available (commercial off the shelf, COTS) optical fiber cable assemblies are characterized for space flight usage under the NASA Electronic Parts and Packaging Program (NEPP). The purpose of this is to provide a family of optical fiber cable options to a variety of different harsh environments typical to space flight missions. The optical fiber cables under test are ...
متن کاملMagnesium and Space Flight
Magnesium is an essential nutrient for muscle, cardiovascular, and bone health on Earth, and during space flight. We sought to evaluate magnesium status in 43 astronauts (34 male, 9 female; 47 ± 5 years old, mean ± SD) before, during, and after 4-6-month space missions. We also studied individuals participating in a ground analog of space flight (head-down-tilt bed rest; n = 27 (17 male, 10 fem...
متن کاملSpace Flight Studies
A standard rodent diet for space flight must meet the unique conditions imposed by the space environment and must be nutritionally adequate since diet can influence the outcome of experiments. This paper evaluates the use of National Aeronautics and Space Administration (NASA) developed Foodbars as a standard space flight diet for rats. The Foodbar’s semipurified formulation permits criteria su...
متن کاملPsychological effects of space flight.
P S Y C H O L O G I C A L EFFECTS of space flight may arise from central nervous system changes produced by physiological stress or from emotional reactions to various aspects of the flight. Since either of these may disrupt crew performance or impair the health of crew members, potential sources of adverse psychological change must be identified and steps to control it must be taken. Man's beh...
