Dynovasrsquo; Motorless Expandable Solar Array (MESA) system provides a novel solution that specifically addresses NASArsquo;s call for technologies enabling structural and mechanical innovations for a 50-kW-class solar array that can be relocated and deployed at least 5 times.nbsp; This solution was developed based on previous technologies that have proven track record such as inflatables and bistable composites and new technologies for deployment and packaging that specifically address the unique mission requirements for large deployable solar arrays.nbsp; The MESA system is unique in that uses multiple technologies developed by Dynovas personnel to achieve this innovation.nbsp; These include:nbsp;Bistable Composites ndash; Lightweight composite materials that provide motorless deployment force and strong structural support when deployed.nbsp; Because this technology has no moving parts it is naturally dust resistant.Inflatable Technologies ndash; These are lightweight and motorless deployment systems that house the solar arrays.nbsp; The use of gas pressure provides deployment AND retraction forces, making the need for no motors.nbsp; With no moving parts, the inflatable is inherently dust resistant.Mechanical and Structural ndash; Use of self-tensioning guy wires and ratcheting system provide a safe and repeatable system for deployment and stowage. nbsp;These are necessary to stabilize an array of this size on an uneven terrain.Novel Packaging Solutions ndash; By packaging the arrays within the base structure, the system is compact and modular for launch, deployment, stowage and relocation.nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; Using these technologies together, Dynovas was able to develop a solution for a deployable solar array that meets the requirements for the next generation 50-kW deployable solar array that can be lifted 10m high to avoid shadowing
