simple techniques which may provide construction materials at lower cost and with reduced development time. SSI, in conjunction with Alcoa Goldsworthy Engineering of Torrance, CA, has begun an investigation into glass-glass composites made from lunar material. Using simulant materials, Goldsworthy first produced glass fiber products and then developed a lower melting temperature glass matrix. The first successful glass fiber and matrix combinations were produced in 1988 [26]. Another resource processing area which is following the same trend towards simpler processing techniques is the use of man-made space debris as construction feedstocks. Specifically, SSI is examining the possibility of using spent shuttle external
