Affordable Maximum Performance Solar Array System with IMM PV for NASA Space Science & Exploration Missions, Phase I

Completed Technology Project

Project Introduction

Affordable Maximum Performance Solar Array System with IMM PV for NASA Space Science & Exploration Missions, Phase I
Deployable Space Systems, Inc. (DSS) will focus the proposed NASA Phase 1 program on the development and validation of ROSA-Max, a significantly structurally/electrically optimized version of the basic ROSA solar array technology with advanced ultra-lightweight structures and IMM photovoltaics. The combined embodiment with advanced ultra-lightweight structures and IMM photovoltaics offers maximum performance in all key metrics and unparalleled affordability for NASA Space Science missions. ROSA-Max will enable emerging Solar Electric Propulsion (SEP) Space Science missions through its ultra-lightweight, ultra-compact stowage volume, ultra-affordability, high strength/stiffness, and its high voltage and high/low temperature & illumination operation capability within many environments. The ROSA-Max technology will provide NASA/industry a near-term and low-risk solar array system that provides revolutionary performance in terms of high specific power (>300-500 W/kg BOL at the wing level, PV-blanket dependent), affordability (>50% projected cost savings at the array level, PV-blanket dependent), ultra-lightweight, high deployed stiffness (10X better than current rigid panel arrays), high deployed strength (10X better than current rigid panel arrays), compact stowage volume (>60-80 kW/m3 BOL, 10X times better than current rigid panel arrays), high deployment reliability and operation reliability, high radiation tolerance, high voltage operation capability (>200 VDC), scalability (500W to 100's of kW), and LILT & HIHT operation capability (LILT – Low Intensity Low Temperature, HIHT – High Intensity High Temperature).
