Aouda.X, spacesuit simulator for planetary surface exploration

Aouda.X is a novel spacesuit simulator developed by the Austrian Space Forum. It is not a real suit, but simulates the functions and feel of a spacesuit that would possibly be used by the astronauts on a planetary surface. This lets us learn here on Earth how difficult it is to operate and perform science on a distant planetary body.

With a helmet featuring a Head-Up Display (HUD), full air circulation with carbon dioxide control, medical monitoring for safety, joints and gloves emulating the stiffness of a real suit and radio equipment, Aouda.X is a perfect way to simulate extravehicular activity on a planetary surface.

An advanced human-machine interface, a set of sensors and purpose-designed software act as a local virtual assistant to the wearer. It is designed to interact with other field components like the rover and instruments.

System Overview

Aouda.X
  • Mass less than 45 kg
