Future space missions involve both a long-duration and long communication delays (up to 30 seconds for Near Earth Asteroid / Near Earth Orbit missions and up to 40 minutes for Mars missions). These factors mean that training crewmembers for these missions requires durable training, surviving long delays between training and actual use of the learned knowledge and skills. Yet, the current intervals of on-board-training (OBT) for emergencies and to maintain currency on EVA and the robotic arm are largely based on anecdotal experience. Furthermore, all our theories and knowledge about skill acquisition, retention, and transfer to new situations are based on studies conducted at university laboratories with undergraduate students as research subjects. We do not know how well these studies apply to astronauts in space operations.
We do not know how well crews retain knowledge trained pre-flight, how well the knowledge transfers, how frequently critical skill should be refreshed, or what type of information or guidance need to be available for autonomous crews in terms of Just-in-Time (JIT) training and performance support tools.


Three specific aims are included in this study:

  1. Test the retention and transfer of specific technical content learned pre-launch to assess the need for (and possible schedule of) onboard refresher and JIT training.
  2. Compare the process of skill decay on orbit with that of a closely matched subject on Earth, and with that of university undergraduate students on Earth.
  3.  Collect naturalistic data from onboard and previously flown crew on training-related crew performance including: performance errors, requests for ground support, need to review previously learned material, and training success stories. 

These results, along with results from the subsequent Training Retention – Flight Validation study, will help close the gap on how to determine retention in operational spaceflight and will identify information and guidance likely to be needed in the form of refresher training, JITT, or performance support tools.

The study addresses interests of three different Elements within the Human Research Program (HRP), and will thus be a close collaboration among these elements: Human Factors and Behavioral Performance (HFBP) and (ExMC) Exploration Medical Capabilities.
