History of Underwater Simulation of Weightlessness for Extravehicular Activity (EVA) Training, Part 1

Discipline: Environmental Control/Life Support An attempt to clarify some vague memories of underwater studies of astronaut capabilities in space led Dr. John Charles to become acquainted with Sam Mattingly, one of the pioneers in the field, and to greater insights into Mattingly’s work simulating Gemini EVAs in the mid-1960s. Charles recounted major accomplishments by Environmental Research Associates (ERA), Mattingly’s company for contracting with NASA Langley on several early studies. ERA’s work was considered within the context of contemporary efforts to simulate weightlessness and the widespread development of neutral buoyancy facilities after ERA’s successful demonstration for Gemini 12.
