Costing the Mission Architecture Method 1 Method 2 • Assumptions • Launch Cost: $10K / kg (Smith 1/17/2007) • Total Cost = 2*(Launch Cost) • Overestimate Mass • IMLEO = 20,000 mt • ~ 170 Ares V payload capacity • Architecture Cost: $400 Billion • Underestimate Mass • IMLEO = 5,000 mt • ~ 45 Ares V payload capacity • Architecture Cost: $100 Billion • NASA AMCM equation (Larson 943-947) • Input: 6 architecture parameters • Output: Total program cost • Overestimate Mass • IMLEO = 20,000 mt • ~ 170 Ares V payload capacity • Architecture Cost: $550 Billion • Underestimate Mass • IMLEO = 5,000 mt • ~ 45 Ares V payload capacity • Architecture Cost: $220 Billion
Costing Conclusions • Project Cost Goal • Architecture Cost: < $200 Billion (2007) • Cost Drivers • Mass injected to LEO • Technology Readiness Level • Cost Constraints • NASA yearly budget • Low Risk
