Ysfunction is induced by low dose HZE irradiation. Mitochondrial dysfunction can be a main concern for the health and security of deep space astronauts. Mitochondrial dysfunction in liver will not be the only HZE-induced concern, these effects may also be very detrimental in brain and cardiac tissues which have higher cellular concentrations of mitochondria. As we appear to travel deeper into our galaxy, mitochondrial effects are of good danger for these missions because the HZE contained inside GCR effects may very well be additive together with the effects that have been observed on the ISS from things including microgravity, dehydration, hypoxia, stress, and high levels of microbial containment [546]. One particular other aspect that could exacerbate these problems additional once on the surface of the moon, Mars, or other stellar body is exposure to space dust. Lunar hay fever was a term coined for the duration of the Apollo moonInt. J. Mol. Sci. 2021, 22,31 ofwalks, which was an NPY Y5 receptor Antagonist Accession allergic reaction to lunar dust that the astronauts brought in to the space craft on their suits after surface exploration. Other studies have shown that exposure to meteorite dusts induces increases in ROS and inflammatory responses [57] which can be probably linked towards the higher levels of iron (III) oxides in meteorite dusts [58]. The effect of GCR exposure, microgravity, space flight stressors, and exposure to immunogenic space dusts will minimally be additive for the deep space traveler. Countermeasures targeted at enhancing mitochondrial function, decreasing ROS, and reducing unbridled immune response induced by GCRs, microgravity, in-flight stressors, and exposure to “novel space antigens” which include space dusts are going to be important to decrease cognitive decline, cardiac toxicity, and carcinogenesis for the duration of and after deep space journeys.Author Contributions: Conceptualization, M.R.E., R.L.U. and B.L.B.; Methodology, M.R.E., B.L.B. and Y.Y.; Formal evaluation B.L.B. and M.R.E.; Sources M.R.E.; Information curation, B.L.B.; Writing–original draft preparation, B.L.B. and M.R.E.; Writing–review and editing, M.R.E. and B.L.B.; Visualization M.R.E.; Supervision M.R.E.; Project administration M.R.E.; Funding acquisition M.R.E., R.L.U. and B.L.B.
