Analog Astronauts
Analog astronauts are specifically trained spacesuit tester. After an extensive selection process they run through a several month long basic training. Analog astronauts are used for technical tests and Mars simulations.
OeWF analog astronauts are specifically trained for the OeWF Mars spacesuit simulator “Aouda” and are assigned “in analogy to” future human (Mars) expeditions for preparatory research and development projects.
