Welcome to the Systems Analysis and Concepts Directorate at NASA Langley Research Center

Defining the Art of the Possible

The Systems Analysis & Concepts Directorate (SACD) informs decision makers of the art of the possible.  We can examine existing systems or define future Architectures, Vehicles, or Operational Concepts across the trade space within a physics-based, multidisciplinary, variable fidelity environment to determine the performance, cost, risk, and schedule feasibility and systems requirements to enable informed technical, programmatic, and budgetary decisions.

From rockets to satellites, robotic precursors to human habitats, UAVs to commercial transports to hypersonic flight, from looking at the airspace we fly in to the air we breathe, SACD is helping move NASA forward.
