Conclusions A design study of parabolic solar concentrators as created out of triangular mirrors was performed. The mirror segment models which are the key elements were constructed and tested. Results are good so far. Our next steps are to review the design studies, and to confirm the durability of the fabricated mirror when exposed to the environment of space. We also plan to fabricate a new mirror with a resin specular surface. This could possibly be lighter and with smaller thermal deflection than the glass ones constructed for this study.
