In today's rapidly evolving space environment, our department leverages both heritage and state-of-the-art knowledge, tools, and techniques in the areas of space vehicle attitude control, dynamics, and estimation and payload pointing, while also researching and applying methods from emerging and related topics such as artificial intelligence and robotics, to solve new and increasingly challenging problems. Comprised primarily of highly-trained mechanical and aerospace engineers, VSD provides national expertise in the areas of vehicle engineering; guidance, navigation, and controls; robotics; electro-mechanical devices; embedded systems; fluid mechanics; propulsion; thermal control; mechanisms; structures; structural dynamics; and dynamic environments.
