Long-duration missions place astronauts under immense stress and workload performing science experiments and maintaining space systems. High stress levels are shown to be detrimental to crew health due to immune system suppression and the increasing susceptibility to disease.

Crew support by an artificial intelligence (AI) could assist the crew in complex science experiment and maintenance duties. The Crew Interactive MObile companioN (CIMON) is just such a device. This device is a non-interventional, observational sphere developed to obtain insight into the effects of AI on crew support during long-term missions in space. CIMON interacts directly with the crew using verbal commands and has access to software and components, similar to that of the ground based IBM AI called ‘Watson”.

CIMON will be used to demonstrate how CIMON can:

  1. Support the crew in their daily routine tasks (Maintenance)
  2. Perform mobile video documentation of complex science tasks (Science Support)
  3. Facilitate training of specific motor skills (Skill Training)

The first flight of CIMON will be a technical demonstration and a test of acceptance, feasibility and efficiency of CIMON support. A crew questionnaire will be used to determine the performance and usefulness of AI and to identify possible countermeasures to both prevent stress and reduce expected monotony during long duration space missions.
