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

SMAB enables well-informed decision-making with integrated analysis and assessments of complex space systems, architectures, and portfolios based on benefit, cost, and risk.

Vehicle Analysis

VAB focuses its expertise in designing and evaluating revolutionary aircraft, launch vehicles, and spacecraft to enable advances in aeronautics and space exploration.

Featured Projects

Artist concept of a fully reusable, two-stage-to-orbit space access system.


Hypersonic aircraft travel faster than roughly five times the speed of sound. VAB is working to make routine hypersonic flight in the atmosphere a reality to enable faster travel and access to space.


As NASA plans missions to the Moon and future deep-space destinations, the Agency is developing an advanced in-space platform to be located in orbit around the Moon. Gateway will serve as an outpost for missions to the lunar surface with the Artemis program.

X-57 Maxwell

NASA’s X-57 Maxwell is an all-electric experimental aircraft designed to demonstrate multiple leading-edge technologies. The goal of the X-57 is to demonstrate that an all-electric airplane can be more efficient, quieter and more environmentally friendly than traditional gas-powered airplanes.
