One of the most attractive approaches for deploying and supporting the flexible-blanket version of SLA on orbit is ABLE Engineering’s SquareRigger platform, originally developed for the Air Force Research Laboratory. SLA on SquareRigger could provide very large power arrays (50 kW to MW class) for a variety of future space missions. Fig. 14 (on the following page) shows a schematic of the SLA/SquareRigger array. The stowed package of SquareRigger is a tight bundle of structural tubes with the . . .
