Review of Shuttle Microgravity Acceleration Data: Vibratory and Transient

Abstract

Knowledge about the acceleration environment on the National Aeronautics and Space Administration's Space Shuttle plays an important role in conducting many microgravity science experiments. The Microgravity Measurement and Analysis Program at the Lewis Research Center measures and characterizes the acceleration environment of the Shuttle and other free-fall platforms. The Space Acceleration Measurement System has been the primary source of Shuttle vibratory and transient acceleration data. These data, along with those from other accelerometer systems, have been analyzed by the Principal Investigator Microgravity Services team in order to identify, qualify, and quantify the effects of various acceleration disturbances. This paper highlights and summarizes the results of these analyses.
