Bone Research at NASA: Career Pathway to the Space Program

This viewgraph document is comprised of two presentations about Bone Research at NASA. The first document has slides that show the percent of bone loss from specific bones as demonstrated from research of the Mir cosmonauts, and the required preflight and postflight BMD measurements for long duration flights. The second presentation entitled "Recovery of Spaceflight-induced Bone Loss: Bone Mineral Density after Long-duration Missions as Fitted with an Exponential Function" reviews the recovery of Bone Mineral Density (BMD) after long duration missions. Between 1990 and 2004, 56 missions were flown with 45 crewmembers for an average of 181 days +/- 47 days. For each of these flights the change in BMD was calculated after the flight. The BMD changes were plotted against the number of days for bone recovery after the landing. The plots for the bones that were measured are shown.
