Deployable Space Systems, Inc. (DSS), in partnership with Mark O'Neill LLC (MOLLC) will focus the proposed NASA Phase 1 effort on the development of our innovative SOLAROSA technology. SOLAROSA, named for Stretched Optical Lens Architecture on Roll-Out Solar Array, is a new lightweight, high performance space solar array that enables missions through low cost, lightweight, compact stowage volume, radiation hardness, high voltage capability, scalability to ultra-high power, and LILT/HIHT environment operability. SOLAROSA is a fusion of ENTECH's proven Stretched Lens Array (SLA) concentrator technology with DSS's innovative ultra-lightweight Roll-Out Solar Array deployable structural platform. The proposed Phase 1 program is uniquely focused on SOLAROSA development that provides multi-A.U. operability and large beta axis off-pointing operational capability. SOLAROSA promises to provide NASA/industry a near-term and low-risk solar array system that provides revolutionary performance in terms of high specific power (>400-500 W/kg BOL at wing level), affordability (>50% projected cost savings at the array level), lightweight, high deployed stiffness, high deployed strength, compact stowage volume (>60-80 kW/m3 BOL), reliability, high radiation tolerance, high voltage operation capability, scalability, and LILT & HIHT operation capability (LILT Low Intensity Low Temperature, HIHT High Intensity High Temperature).
