AAE450 Senior Spacecraft Design Project Aquarius Kirk Akaydin Week 3: Feb. 1 st, 2007 Project Manager Cost/Schedule/Risk Analysis This Week: Cost Scheduling
AAE450 Senior Spacecraft Design Project Aquarius Assumptions for budgeting Project Aquarius –Development Cost 50% of total cost : spread evenly over 10 years directly preceding item launch –Launch Cost 30% of total cost : assessed year of first launch (based on Apollo analysis) –Refurbishment Cost 20% of total cost : assessed 5-12 yrs later –IMLEO: 9814 mt (~82 Ares V) –AMCM model (Larson )
AAE450 Senior Spacecraft Design Project Aquarius Assumptions for mission budget –60%* of NASA’s budget allotted to Mars missions (*on average) –0.1% budget increase yearly (inflation adjusted) Our budget (FY2007) –Yearly: ~ $11 Bil. –35 yrs: ~ $420 Bil. Budget Plan –Budget buffer –Always <= 81% NASA Total budget –Always have enough funds
