Extra-Vehicular Activity Space Suit Simulator (S3)
Aurora Flight Sciences
Cambridge, MA

Aurora Flight Sciences has teamed up with professors Dana Newman and Jeffrey Hoffman of the Massachusetts Institute of Technology (MIT) Department of Aeronautics and Astronautics to develop an extra-vehicular activity (EVA) space suit simulator (S3).

Due to the limited availability of NASA’s current space suit, the Extra-vehicular Mobility Unit (EMU), it is often impractical for subjects to wear the actual equipment during training or experimentation procedures; the cumbersome mobility units are heavy and bulky as well. Designed to provide astronaut training and research without requiring an actual space suit, the S3 is a low-profile, lightweight, adjustable garment that mimics the properties of NASA’s familiar EMU.

The compact and easily-donned space suit simulator emulates the joint torques of the current EVA suit, which provide movement and locomotion capabilities. The tunable joint torques also allow the S3 to be used to test future space suit concepts. Aurora will demonstrate the feasibility of several joint designs and develop a concept for the S3 device.
