Starfleet Medical: Knowledge Skills and Abilities of Crew Medical Officers on Exploration Missions

Anticipating the medical skills necessary for deep space exploration missions is one of the greatest space medicine challenges. Spontaneous medical events unrelated to the space environment for which resourcing is severely limited. Novel medical events in the space environment for which are unknown unknowns. Exploration missions are remote, long duration, and low resource which increases the risk and consequences of medical events and require increased crew autonomy.

GMAO Office Note No. 17 (Version 1.3) File Specification for GEOS-CF Products

The NASA Global Earth Observing System (GEOS) model has been expanded to provide global near-real-time forecasts of atmospheric composition at a horizontal resolution of 0.25 degrees (about 25 km). This GEOS Composition Forecast (GEOS-CF) system combines the GEOS weather analysis and forecasting system with the state-of-the-science GEOS-Chem chemistry module (Bey et al., 2001; Keller et al., 2014; Long et al., 2015) to provide detailed chemical analysis of a wide range of air pollutants including ozone, carbon monoxide, nitrogen oxides, and fine particulate matter (PM2.5). Full model description and evaluation of the GEOS-CF tropospheric simulation and forecast skill is given in Keller et al. (2021). For evaluation of GEOS-CF stratospheric composition see Knowland et al. (2021).
