AI Summary

A new study published in Mayo Clinic Proceedings reports that astronauts who complete space missions longer than 90 days experience a higher incidence of hip fractures compared with those on shorter flights and with non‑astronaut populations. The research highlights a specific risk associated with extended microgravity exposure, suggesting that current health monitoring may be insufficient for long‑duration missions. Authors call for broader, long‑term skeletal assessments to better protect astronaut bone health.
