Paper Abstract

The quest for knowledge and understanding of the universe has consumed almost everyone at one time or another. Because of this, modern history is full of events in the parallel search for instruments and technology that will better allow this search to continue, that will allow us to seek even further and more faint celestial objects. The progress of this technological search has led to steadily larger telescopes. It has now reached a point of demand for primary objective elements that are so large and accurate that their specifications typically exceed the capabilities of the available materials and manufacturing processes. With apertures in excess of 10 m in diameter now being specified, only multiaperture or segmented mirror techniques appear viable from the point of view of cost and material.
