The NASA Life Cycle Cost Model

< Cost Models


The Life Cycle Cost Model. The Life Cycle Cost (LCC) Model is the latest cost model in use for assessment and analysis.


Point of contact: Edgar Zapata NASA KSC


This model is:

  • A collection of historical cost data

  • A collection of cost estimates for new space systems based on historical cost data

  • Models that combine historical cost data, cost estimates for new systems and cost estimating relationships, for the assessment of either a launch system or a whole human spaceflight exploration architecture composed of launchers and in-space elements such as spacecraft, landers, etc.

The first model is the "Launch System Life Cycle Cost Model"

The Launch System LCC model can be used to generate cost estimates for a semi-reusable / launch system (a system that may have an expendable 2nd stage for example). These cost estimates are outputs. The inputs the model requires are descriptive, asking that a user describe the technical (design, technology) and the non-technical (process/practice) characteristics of the launch system concept.

The second model is the "NASA Scenarios Model for Human Exploration & Operations Budgets vs. Life Cycle Costs"

The NASA Scenarios model does not generate primary cost estimates for space systems (unlike with the Launch System LCC Model). Rather, cost estimates are inputs and the value added is in providing a budget context inclusive of other human spaceflight functions (mission ops, space flight support, etc.) for understanding the feasibility of proposed concepts as scenarios.
