Figure 11.2 Sensitivity Analysis of Energy Conversion and Power Transmission Systems Costs in Spacecraft Segment Space Construction and Support This segment includes all the facilities and activities required to build the satellite formation. This include space stations, construction facilities, manpower operations, logistics, etc... According to NASA/DOE study, the main costs are shown in Table 11.9. Table 11.9 Space Construction and Support Segment Costs The recurring costs for this segment are $165B and represent 7% of the total space power program cost. Due to this small percentage the total cost is not sensitive to this segment so no further sensitivity assessment was performed. Transportation This segment includes all the vehicles needed to built the satellite configuration. It includes Heavy- Lift Launch Vehicles (HLLV), Cargo Orbital Transfer Vehicles (COTV), Personnel Launch Vehicles (PLV), Personnel Orbital Transfer Vehicles (POTV), Personnel Modules (PM), Intra Orbital Transfer Vehicles (IOTV) and Ground Support Facilities. The main costs according with NASA/DOE study are shown in the Table 11.10.
