Abstract :

Usability, acceptability, and habitability questionnaires have previously been developed and implemented by the National Aeronautics and Space Administration (NASA) to collect human factors engineering feedback about both operational and prototype space habitats. During a twelve-day simulated space mission at the Integrated Lunar/Mars Analog Habitat at the University of North Dakota, three crew members submitted habitability feedback using an adapted NASA questionnaire to measure the types, novelty, and priorities of feedback collected using space simulation as a human-in-the-loop (HITL) testing method. Of the categories surveyed, habitat equipment, environment, interface, and crew health were the most frequently reported feedback, followed by operations, activities, and use errors. The crew reported no feedback for recreation or group interaction. Most feedback for habitability items with the priority ‘must be addressed’ occurred by the second mission day. However, novel feedback with the priority ‘nice to have’ sustained new reports throughout the simulation. This study showed that short-duration mission simulations can be a useful HITL testing method to solicit actionable engineering feedback.
