When pediatric cancer survivor Hayley Arceneaux and a trio of crewmates spent three days in space in 2021 as part of SpaceX's Inspiration4 mission, they made history not only as the first all-civilian team to orbit Earth. New research based on this data details changes in the brain, heart, muscles, kidneys and skin, immune regulation and stress levels and a breakdown in the activity of subcellular structures called mitochondria amid the microgravity environment, increased radiation and other factors in space. "We did not see anything that was worrisome, thankfully," said Chris Mason, a professor of physiology and biophysics at Weill Cornell Medicine in New York who helped lead the research, with studies published on Tuesday in Nature and other journals.
