Boneloss in Space

... well kind of. Bone loss and muscle degeneration occur much more rapidly in space where astronaut's bodies are not required to support as they would be in an environment with gravity. It has been shown that the longer an astronaut remains in space, the more damaging the irreversible effects of bone loss are. For astronauts going to Mar's this will be a big concern, as there is the potential for complete osteoporosis during the extended duration mission. Roger Long, with the support of the National Space Biomedical Research Institute, is researching ways to help combat this negative effect of long term space flight.
