─The National Aeronautics and Space Administration (NASA) is currently working to return humans to the moon. multiple space vehicles will be utilized. In the execution of this, a plethora of in-space, dynamic events will occur, many of which require on-board crew to be awake and alert. During system and mission design, vehicle flight profiles are calculated and disseminated with a crew awake-sleep profile developed as an end product of analysis cycles. This singular crew awake-sleep profile is then integrated into the following design analysis cycle for assessment by the medical operations community. To enable faster roundtrip design and analysis of flight trajectory with crew awake-sleep implications, a novel approach and tool, HLS Yawn Prevention 'N' Outer Space (HYPNOS), was created for the Human Landing System (HLS) program out of Marshall Space Flight Center (MSFC) and has been used recently to great effect. Instead of manually crafting the crew sleep timeline based on pre-determined sleep requirements and other flight rules, these constraints are ingested into the MATLAB-based tool. The tool then automatically generates an initial assessment of a sleep schedule that violates the fewest crew requirements and / or maximizes crew sleep and performance. This is performed for the hundreds of flight trajectories that are available to ingest. The quality of these sleep shift profiles is also aggregated into an overall ' "heatmap ", presenting a distribution of the best options and suggesting what the stressing requirements are. Analysis assessments are delivered to mission planning Subject Matter Experts, the medical operations community, and the Flight Operations Directorate (FOD) periodically to aid in the Integrated Analysis Cycles. This integrated approach to design and analysis of crew sleep schedules with the HYPNOS tool is reminiscent of assessments performed by the NASA Jet Propulsion Lab's (JPL) Team X and the European Space Agency's (ESA) Concurrent Design Facility (CDF). The HYPNOS tool is reducing the risk and cost of complicated manned space mission planning for NASA in the HLS program.
