• Rittweger et al. 2010, read in full, finds 56 days of strict bed rest produced tibial epiphyseal bone loss that was almost exclusively cortical, with virtually no trabecular loss

• The ground analog that fits bone better than muscle — head-down bed rest as a readout-dependent model of spaceflight musculoskeletal loss, and how matching the instruments inverted the field's working assumption

• Böcker et al. conclude that 60 days of bed rest without countermeasures models six-month spaceflight lower-limb bone loss, while equivalent muscle loss requires about 80 days

• A site- and instrument-matched pQCT comparison finds bone loss comparable between 6-month spaceflight and 2-month bed rest, while muscle loss shows the expected ~2x under-run

• Does a duration- and site-matched study confirm that head-down bed rest under-runs spaceflight BMD loss, not just turnover markers?

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

• Head-down bed rest of 42–90 days produces bone-mineral-density losses averaging about 1% per month at the hip, pelvis, and heel

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

• Head-down bed rest under-runs spaceflight bone loss by about twofold on turnover markers but nearly matches it on monthly BMD-loss rate

• Prolonged head-down bed rest is the standard ground analog for spaceflight bone loss, bridging aerospace physiology and clinical disuse osteoporosis
