Commander Peggy Whitson works on the OsteoOmics bone cell study that uses the Microgravity Science Glovebox inside the U.S. Destiny laboratory in May 2017. OsteoOmics investigates the molecular mechanisms that dictate bone loss in microgravity by examining osteoblasts, which form bone, and osteoclasts, which dissolve bone. (NASA)
