The main conclusion from the workshop is that AG during long-duration space missions is feasible from an engineering perspective, and that three types of scenarios should be considered: centrifugation inside a space vehicle; spinning part of a vehicle; or spinning the whole vehicle.

Because it has become of concern that astronauts might experience increased intracranial pressures in space as a result of the weightlessness-induced fluid shifts, the use of AG could provide the best solution for human health protection during long-duration deep space missions. If so, the most-likely future AG scenarios in space will probably constitute 1) intermittent intravehicular, 2) intermittent part-of-vehicle, or 3) continuous whole-vehicle centrifugation.

If so, the most-likely future AG scenarios in space will probably constitute 1) intermittent intravehicular, 2) intermittent part-of-vehicle, or 3) continuous whole-vehicle centrifugation. Technical feasibility studies have indicated that continuous, whole-vehicle centrifugation is possible during a transit to Mars, but physiological requirements such as G-level and rotation rate have not yet been defined. This information is needed before AG-configuration concepts can be determined. Results of previous ground studies have shown some protective effects of intermittent short-radius centrifugation on muscle, bone, the central nervous system, heart, and circulation. More research, however, is needed to better understand the relationship between physiological responses and G-levels between zero and one. AG rodent research on the International Space Station (ISS) can be a starting point in 2015 with NASA and Japan Aerospace Exploration Agency (JAXA) rodent habitats. Several ground-based short-radius human centrifuges are available worldwide for ground- based intermittent AG research, whereas only a few long-radius centrifuges exist for long-duration exposures (United States and Russia). Thus, for definition of the physiological requirements to the engineering community, NASA should initiate an AG research program encompassing animal investigations on the ISS and short- and long-radius centrifugations in humans on the ground to 1) identify the specific gaps associated with possible AG profiles, 2) perform trade-off feasibility analyses between potential AG profiles and non-AG solutions, and 3) initiate international collaboration for the most efficient and strategic use of available resources.</p>...9781311416902_Progressive Managementlibro_electonico_28ad50b4-2062-3405-a9e4-05d3394005c4_9781311416902;9781311416902_9781311416902Progressive ManagementInglésMéxicohttps://getbook.kobo.com/koboid-prod-public/smashwords-epub-5441ae5d-ac4c-425a-8b38-281da535682b.epub2015-04-30T00:00:00+00:00Progressive Management
