About SACD


Systems Analysis and Concepts Directorate

We solve problems associated with aeronautics, exploration, and science by analyzing advanced aerospace system concepts for NASA decision makers and programs.

We design future concepts and analyze them in an operational context to determine systems level outcomes.

Directorate Objectives

Mission, Concept, and Trade Analysis: Studying and designing how the project’s mission should function and be carried out
Life Cycle and Uncertainty Analysis: Evaluating the impacts that design decisions have on a system and how it affects the system’s life cycle
Technology Assessment and Portfolio Analysis: Studying and designing how a project’s mission should function and be carried out with regards to technology
Risk Analysis: Identifying the likelihood and consequence of a potential future event

We do this by performing system analysis and working with other NASA centers, along with industry, academia, Department of Defense and other government agencies.

Together, we’re able to collaborate on programs and projects like On-Demand Mobility, Asteroid Robotic Redirect Mission, and the Space Launch System.
