The proposed Mega-ROSA-EX technology promises to provide NASA a near-term and low-risk solar array system that provides revolutionary performance in terms of ultra-high power (100's of kW to 10's of MW), high specific power (>200-500 W/kg BOL at the wing level depending on PV), affordability (up to >50% projected cost savings at the array level with concentrators), light weight, high deployed stiffness, high deployed strength, ability to react maneuvering accelerations, compact stowage volume (>50 kW/m3 BOL), reliability, high radiation tolerance, high voltage operation capability, scale-ability, and LILT & HIHT operation capability. The proposed highly-experienced team and unique capabilities will catalyze commercial infusion and rapidly increase Mega-ROSA-EX technology readiness. The predicted performance metrics for the Mega-ROSA-EX technology are incredible improvements over current state-of-the-art, and in many cases are mission-enabling for future NASA Exploration missions and other NASA applications, and particularly for NASA's deep space solar electric propulsion (SEP) high-voltage and high-radiation missions, space-tug missions, and large area Planetary / Lunar surface missions. Space applications are comprised of NASA missions that require large-power production through deployment of photovoltaic devices. Ultra-high power applications include high power spacecraft, Solar Electric Propulsion (SEP), space-tug, etc. Non-NASA space commercial applications are comprised of practically all DoD, and commercial missions that require large-power production through deployment of photovoltaic devices. Ultra-high power applications include high power spacecraft, Solar Electric Propulsion (SEP),and high-power telecommunications DoD customers may take advantage of the high-stiffness / strength capability for reacting maneuvering loads associated with rapid-response surveillance missions.
