Fluidic Shaping and in-situ Measurement of Liquid Lenses in Microgravity [PDF]

arXiv, 2022
In the absence of gravity, surface tension dominates over the behavior of liquids. While this often poses a challenge in adapting Earth-based technologies to space, it can also provide an opportunity for novel technologies that utilize its advantages. In particular, surface tension drives a liquid body to a constant-mean-curvature shape with extremely ...

The impact of 60 days of ‐6° head down tilt bed rest on mitochondrial content, respiration and regulators of mitochondrial dynamics

The Journal of Physiology, EarlyView., 2023
Abstract figure legend Reductions in skeletal muscle mitochondrial respiration following 60 days of bed rest explained by a decrease in mitochondrial content, but resulting in an increase in OPA1 and Drp1 mediated mitochondrial fission. Abstract It is unclear how skeletal muscle metabolism and mitochondrial function adapt to long duration bed rest and ...

Nanopore sequencing in microgravity [PDF]

npj Microgravity, 2016
AbstractRapid DNA sequencing and analysis has been a long-sought goal in remote research and point-of-care medicine. In microgravity, DNA sequencing can facilitate novel astrobiological research and close monitoring of crew health, but spaceflight places stringent restrictions on the mass and volume of instruments, crew operation time, and instrument ...

Dependence of cyanobacterium growth and Mars-specific photobioreactor mass on total pressure, pN2 and pCO2

npj Microgravity
In situ resource utilization systems based on cyanobacteria could support the sustainability of crewed missions to Mars. However, their resource-efficiency will depend on the extent to which gases from the Martian atmosphere must be processed to support ...

Experimental and numerical study on capillary flow along deflectors in plate surface tension tanks in microgravity environment

AIP Advances, 2019
Surface tension tanks are the most widely used satellite propellant tanks, which use liquid surface tension for liquid transportation and gas-liquid separation to provide pure propellant for thruster.

Surface tension and microgravity [PDF]

European Journal of Physics, 2014
The behaviour of confined liquids on board an orbiting spacecraft is mainly driven by surface tension phenomena, which cause an apparently anomalous response of the liquid when compared with the behaviour that can be observed on an Earth laboratory provided that the amount of liquid is high enough.
