- Spaceflight osteopenia
Spaceflight osteopenia refers to the characteristic
bone lossthat occurs during spaceflight. Astronauts lose an average of more than 1% bone mass per month spent in space. There is concern that during long duration flights, excessive bone loss and the associated increase in serum calciumion levels will interfere with execution of mission tasks and result in irreversible skeletaldamage.
