Simulations and analogs (test-beds)

Abstract

Space is not readily accessible for research and training and is costly. Many space environmental factors can be readily reproduced on Earth. However, prolonged microgravity and the full spectrum of radiation are difficult to replicate under Earth’s conditions. Substitute test-beds to probe hazards, address medical risks, and allow familiarization with the novel space environments offer a potential solution to access and cost constraints. All test-beds present unique hazards and health risks of which medical personnel should be cognizant. Understanding risks and familiarity with appropriate monitoring of subjects and astronaut help, together with proper interventions, will minimize health complications and improve operational safety. Familiarity of the test-beds safety ratings and institutional (ethics) review boards process will help ensure health and wellbeing in all exposure to environmental extremes.
