In 2006 I was approached by Rigel Woida, friend and fellow student at the University of Arizona College of Optical Sciences.  He was working on a NASA grant for a Mars Reflector system.  The idea was that using large, inflatable mirrors in Mars orbit, you could focus enough light continuously on one area so that the average ambient temperature of that area would increase.  You could provide enough light to maintain a constant raised temperature over a landing site or survey area, enabling simplified human exploration gear.  I completed several conceptual illustrations of the system in orbit and viewed from the surface.  Also, I worked with Rigel to create concept designs of the reflector craft and the potential inflation design.
