Abstract

The current debate in the U.S. Human Spaceflight Program focuses on the development of the next generation of man-rated heavy lift launch vehicles. While launch vehicle systems are of critical importance for future exploration, a more comprehensive analysis of the entire exploration infrastructure is required to avoid costly pitfalls at early stages of the design process. This paper addresses this need by presenting a Delphi-Based Systems Architecting Framework for integrated architectural analysis of future in-orbit infrastructure for human space exploration beyond Low Earth Orbit. The paper is structured in two parts. The first part consists of an expert elicitation study conducted between November 2011 and January 2012 involving fifteen senior experts and decision-makers concerned with human spaceflight in the United States and Europe. The elicitation study included the formation of three expert panels representing exploration, science, and policy stakeholders to be engaged in a 3-round Delphi study. Rationale behind the Delphi approach, as translated from social science research, is discussed. A novel version of the Delphi method is presented and applied in the context of technical decision-making and systems architecting.
