The recent successful interception of a ballistic missile in flight recalls earlier fevered debates of the 1980s and 90s over the “feasibility” of missile defense. Back then, “settled science” declared that missile defense was either impossible, or of such technical difficulty as to make the eventual deployment of a working system extremely unlikely. Although such “expert” judgment aligned more with political inclination than with sound technical assessment, it served its intended and useful media purpose of providing “proof” that SDI (Strategic Defense Initiative), initiated in 1983, would never work. A similar set of circumstances exists today, as development and use of space resources to create new spaceflight capabilities faces familiar objections and roadblocks.
Leveraging access and capability in space through the use of the material and energy resources found in space gained traction during the initial study phases of SDI. Such a connection is logical – SDI was a program designed to establish a significant space presence by using a number of satellite assets with widely varying requirements (depending on their function: observation, monitoring, interdiction, or protection). Research initially focused on the deployment of unmanned systems from Earth, but it soon became apparent that the significant mass requirements needed by ...
