Simulating Movement in Reduced Gravity

Live Video Chat: Active Response Gravity Offload System, or ARGOS

"NASA Explorer Schools invites students in grades 9-12 from across the U.S. and Departments of Defense and State schools to participate in a special live video web chat with Larry Dungan, project manager and electrical engineer designer for the Active Response Gravity Offload System. Dungan will answer student questions about ARGOS, a computer-controlled overhead crane system that allows a human test subject to move in a simulated reduced-gravity environment, such as the moon, Mars or space."
