My presentation at the International Space Development Conference in May of 2024 on the impact of the Gravity Prescription on the future of space settlement.
JAXA finally released the results of their 2019 study on mice subjected to 1/6 G partial gravity in a paper in Nature in April 2023. The good news is that 1/6 G partial gravity prevents muscle atrophy in mice. The downside is that this level of artificial gravity cannot prevent changes in muscle fiber (myofiber) and gene modification induced by microgravity. There appears to be a threshold between 1/6G and Earth-normal gravity, yet to be determined, for skeletal muscle adaptation.
Study conducted by 100 Year Starship®, founded and led by former astronaut Dr. Mae Jemison, and University of California, Irvine and professor Ronke Olabisi, Ph.D. The team collaborated on the study entitled “Challenges and Benefits to Human Operations in Variable & Partial Gravity Earth Orbiting Habitats“
