• Manned manipulator modules are not cost effective because of the high propellant consumption. 2.2.4.3 Support Equipment Requirements Preliminary definition of support system requirements have been established for the low altitude and high altitude assembly sites using data generated during NASA studies of space stations, research applications modules and remote teleoperator vehicles. Figure 2-26 summarizes the transportation and assembly approach used as a strawman in establishing support equipment requirements. The following lists the major equipments over and above the basic transportation systems required in support of assembly at the two candidate assembly sites: Fig. 2-26 Transportation and Assembly Elements Figure 2-27 summarizes the weight and cost factors assumed in the overall cost assessment of the SSPS assembly operation. To achieve consistency of data, the $/Kg non-recurring and recurring cost estimate for the Space Station has been applied to the cost of all support equipment.
