The various Surface systems can be combined in a very wide variety of options. Three surface architectures were developed in support of LCCR:

Rapid Outpost Buildup (Trade Space‐1) • Deliver as much outpost capability as soon as transportation system permits •Full‐up outpost based on the recommendations from LAT‐2. • Substantial robustness through element duplication

Initial Mobility Emphasis (Trade Space‐2) •Temper outpost build‐up based on affordability with initial emphasis on mobility capabilities •Full‐up outpost has less volume and limited eclipse operating capability than TS1 • Robustness achieved through functional reallocation

Initial Habitation Emphasis (Trade Space‐3) •Temper outpost build‐up based on affordability with initial emphasis on core habitation & exploration capabilities •Full‐up outpost has less volume and limited eclipse operating capability than TS1 • Robustness achieved through functional reallocation Lunar Transportation Figures of Merit

A comprehensive set of high-level FOMs must cover four or five major areas:

– Affordability - Comparison(s) between the projected costs of the campaign and the projected budget

– Benefit - Measure(s) of the total worth or value produced by the campaign across all themes of interest; including benefit items (e.g. science, operation experience, and public engagement) and indirect benefit items (e.g. extensibility to other destinations, enablement of future lunar activities)

– Safety & Mission Assurance - Measure(s) expected losses due to the uncertainty or reliability of the system

– Programmatic Risk - Evaluation of the likelihood and consequence of changes in the performance of the campaign due to multiple types of programmatic uncertainty (component performance, technology development, schedule, budget, reliability, etc.)

– Sustainability - Measure(s) of the campaigns ability to maintain a level of value (or perceived value) over time that justifies continued investment in the program Campaign Sensitivity 1600 40000
