TBONE - Advanced analysis of bone structural trajectories in long-duration space flight — Astronauts lose bone mass rapidly while in space. Some bone may recover after returning to Earth, but bone structure may be permanently changed. The ends of long bones are made of porous bone connected by thin rods and plates called trabeculae. When bone is lost, trabeculae thin and separate from one another, reducing the strength of the bone. With advances in high-resolution bone imaging, we can now measure bone on a scale finer than a human hair and assess changes in individual trabeculae. This study will discover how individual trabeculae change in response to microgravity and whether these structures recover after returning to Earth.
