positioned by the SSRMs using a Manipulator Foot Restraint (MFR) while the other will remain on the APS (Fig. 13c). The radiator will be deployed manually by the EVA crew using an EVA torque tool. For concentrator assembly, the EVA crew will be positioned on the APS as shown in Fig. 14a. A grapple fixture will be mounted on the back side (non-reflective surface) of the central hexagonal panel and grappled by the SSRMS. Each additional panel will be raised from the concentrator container by the EVA crew and latched to the panel above. The wrist joint of the SSRMS will rotate following the latching of each panel to provide clearance and prepare for the latching of the next panel. Once assembly of the concentrator is complete it will be placed on the concentrator support structure by the SSRMS (Fig. 14b). The operations will be planned to avoid positioning the concentrator on-sun until the initiation of start up procedures. Concluding Remarks A design for a Solar Dynamic power module that meets all of the performance requirements for operating on orbit as a power source on Space Station Freedom has
