Systems Analysis and Concepts Directorate
The Systems Analysis and Concepts Directorate (SACD) is located at the NASA Langley Research Center in Hampton, VA and supports the future of aeronautics, exploration, space operations, and science.
Here at SACD, we solve problems associated with aeronautics, exploration, and science by analyzing advanced aerospace system concepts for NASA decision makers and programs.

SACD Branches
Aeronautics Systems ANALYSIS
ASAB is focused on creating advanced concepts and technologies, in relation to aeronautics, to improve connectivity and save valuable resources.
Space Mission Analysis – eXPLORATION
SMAB-EXP enables well-informed decision-making for complex space systems, architectures, and portfolios, focusing on human exploration.
SPACE MISSION ANALYSIS -SCIENCE & TECHNOLOGY
SMAB-S&T enables well-informed decision-making for complex space architectures and systems, focusing on science and technology portfolios.
Featured Projects

Hypersonics
Hypersonic aircraft travel faster than roughly five times the speed of sound. We’re working to make routine hypersonic flight in the atmosphere a reality to enable faster travel and access to space.
Moon to Mars
We’re designing a roadmap for long-term exploration of the lunar surface, our first steps on the Red Planet, and the journey beyond, working with our partners in industry, academia, and the international community.


Quesst
NASA’s Quesst mission, which features the one-of-a-kind X-59 aircraft, will demonstrate technology to fly supersonic — or faster than the speed of sound — without generating loud sonic booms.
