The AstroEdge flight solar array wings for the Small Spacecraft Technology Initiative (SSTI) “Clark” satellite are now in the final stages of assembly and testing. The primary and secondary wing assemblies will be delivered shortly to CTA Incorporated for spacecraft integration and test. Vehicle launch from Vandenberg Air Force Base on the Lockheed launch vehicle is set for 31 August 1996. The SSTI spacecraft is a polar orbit mapping spacecraft used to support various sensor experiments. The array is a concentrator solar array that uses planar mirrors to enhance the level of illumination to the cells to approximately 1.5 suns. The reflectors are arranged to provide a stiff deployed structure and provide cushioning for the GaAs solar cells when stowed during launch. The array is lightweight-the primary wing weight was measured at 6.37 kg and generates 335 watts worst-case EOL for a specific power density of 52.6 W/kg at EOL or 77 W/kg at BOL
