quality. Therefore, the microgravity environment appears to be ideally suited for growing crystals with improved quality ( Kuranova et al., 2011 ; McPherson et al., 1999 ; Snell et al., 1997 ). In this context, it is important to investigate the effect of crystal growth rates versus crystal quality and size.
The first reported protein crystallization experiments in microgravity, performed in 1984, described the growth of lysozyme and b-galactosidase crystals on Spacelab-1 ( Littke and John, 1984 ). Since then in subsequent space shuttle missions, unmanned satellite

Salivary and Serum 8-Hydroxydeoxyguanosine Level in Simulated Microgravity
Background. Microgravity is associated with an increased of peroxidative. The effect is more pronounced after long duration space flight and can even last for several weeks after landing.
Aim. To determine the influence of a simulated microgravity on antioxidant status of the human body.
Material and Methods. 10 healthy volunteers were studied in condition before, during, and just after the simulated microgravity of -6 head -down -tilt (HDT) bed rest for 10 days. We measured the salivary and serum 8-hydroxydeoxyguanosine before, during and recovery of HDT.
Results. The 8-hydroxydeoxyguanosine showed significant increase in simulating microgravity.
Conclusion. The data provides evidence that oxidative stress is among critical nutritional concerns for long duration space travellers.

In early 2016, the Department of Applied Aviation Sciences (AAS) at the Embry-Riddle Aeronautical University (ERAU) was granted a suborbital flight opportunity to work on a Science, Technology, Engineering, and Mathematics (STEM) research project. The Spaceflight Operations team in the AAS department was already developing other suborbital payloads as part of the Arete STEM Project (ARETE) to demonstrate joint commercial spaceflight activities. The main aim of this research was to investigate the effect of microgravity on T-cells and to

There is a large body of research ( Licato and Grimm, 1999 ; Uva et al., 2002 ; Gridley et al., 2009 ; Singh et al., 2010 ; Thiel et al., 2012 ; Hauschild et al., 2014 ; Martinez et al., 2015 ; Nickerson et al., 2016 ) showing that exposure to microgravity leads to suppressed immunity in both rodents and humans. The downregulation of the immune system is measured by a decreased number of T-cells, alterations in immune cell subsets, epigenetic regulation, slower proliferation rate, and other immunological parameters. Altered gravity has
