• Does head-down bed rest quantitatively track spaceflight bone/calcium loss, and by how much does it under-run actual orbital losses?

• In head-down bed rest, bone-resorption markers and PTH suppression run at roughly half their spaceflight magnitude

• In missions longer than 30 days, spaceflight bone-mineral-density loss runs about 0.8% per month at the lower limbs
