Medical Constraints in Spaceflight: Venturing Beyond Low Earth Orbit
… extend the current model of medical care used in spaceflight in low-earth orbit to a model of medical care that will be conducive to exploration space missions. The intent of this project was to identify organizations that are doing research and development or have established products that will …

A Wearable Countermeasure for Musculoskeletal Deconditioning in Human Spaceflight
In the reduced gravity experienced during human spaceflight, the human body no longer experiences the constant loading provided by Earth’s gravity. Muscles atrophy due to disuse, the spine elongates, which may cause back pain and discomfort, and sensorimotor changes lead to impaired posture and …

Effects of Spaceflight on Phagocytic Function and Immune-Neural Interaction
<p>In spaceflight, astronauts will be exposed to several environmental risk factors that may lead to disturbances in homeostasis maintained by the central nervous system (CNS) and immune system. Low Earth orbit (LEO) spaceflight studies have shown that microgravity changes virtually all immune …

Developing individualized ground testing protocols for use of sleep medications in spaceflight
During spaceflight, sleep time are markedly reduced for astronauts. Sleep medications are used by astronauts during space mission for sleep. Spaceflight is an environment where abrupt alarm awakening is always a possibility and during that time high cognitive function and performance may be needed …

Bone Mass Preservation and Fracture Risk Assessment with Bisphosphonate Therapy During Spaceflight
… The great loss of bone due long-duration spaceflight increases fracture risk, jeopardizing the success of the mission and postflight recovery. Bisphosphonates may be able to counteract this bone loss by altering the remodeling process. These drugs increase bone mass, thus reducing fracture …
