Cell Research Experiment In Microgravity (CRExIM) was launched aboard Blue Origin’s New Shepard suborbital vehicle on Tuesday, December 12, 2017, from the West Texas Launch Site in Van Horn, Texas. One of the aims of this science experiment was to assess the effects of microgravity on murine T-cells during suborbital flight. These cells were placed in a NanoLab with a data logger that sensed the acceleration, temperature, and relative humidity during preflight, flight, and postflight operations. Some discrepancies in sensor measurement were noticed, and these errors were attributed partly to the difference in sampling rates and partly to the different …

A Wearable Garment To Mitigate Low Back Pain In Astronauts, Curtis Neeld, Miranda Moore, Alexis Quintana, Audra Romans, Arianne Scheller, Charles Swieczkowski, Nicholas A. Levine, Brandon R. Rigby

International Journal of Exercise Science: Conference Proceedings

The microgravity environment of space is known to cause a wide array of adverse physiological effects on the bodies of astronauts. Among these effects, low back pain due to space adaptation is commonly reported by astronauts. In fact, this pain, caused primarily by atrophy of the erector spinae musculature, has the highest incidence rate among all musculoskeletal-related conditions reported by this population while in space. Low back pain and the consequences of other medical conditions may become magnified as the duration of missions increases over the next few decades. Therefore, determining methods of preventing and mitigating the deleterious effects of …

The phenomenon of sloshing is a substantial challenge in propellant management, particularly in reduced gravity where surface tension-driven flows result in large slosh amplitudes and relatively long decay time scales. Propellant Management Devices (PMDs) such as the rigid baffles and elastomeric membranes are often employed to counteract motion of the free surface. In the present study, we investigate an active PMD that utilizes a free-floating membrane that, under an applied static magnetic field, becomes rigid and suppresses slosh. This semi-rigid structural layer can thereby replace bulky baffle structures and reduce the overall weight of the tank. In this paper, the …
