"In thinking about the how and the why of the economic development of space, mental frameworks are of crucial importance. A mental framework governs everything in terms of how any particular engineering project evolves from concept to implementation. Over time in the space arena our mental framework has evolved, in ways not all together positive from the perspective of those of us who believe that the economic development of space is practical and indeed crucial to the continuing development of our planetary civilization. This missive will explore the mental framework of economic development (the level zero requirement in government speak) and then explore how that would unfold."
