Learn about how important it is to study bone loss in astronauts, due to long exposure of absence of gravity. Also learn how this research can help to prevent or cure osteoporosis in other people than astronauts

Male: America’s first long term presence in space but scientist discovered that astronauts loose bone mass during long flights at a rate of 1% a month. The challenge is to discover a counter measure that is a method of preventing accelerated bone loss seen in astronauts on long duration flights. On Earth, the same research would take 10 years while the data would be no where near as useful. There’s no doubt that the research findings could result in a treatment or cure for osteroperosis much sooner and help us better understand normal bone loss due to aging. By age 70 we’ve all lost 35% of our skeleton. During the 1st 3 to 5 years after menopause women will loss 2 to 4 % percent a year. Studying bone loss in space will greatly enhance our knowledge better base back here on Earth. When NASA artist imagined what the international space station would look like someday, the space scientist already knew how important it would be to use it to study bone density. Results of the study would help develop counter measures for astronaut’s eventual return to Earth and to prepare for human exploration and perhaps even colonization of other planets. How much bone loss can occur in the absence of gravity before irreversible damage is done? What exercises and dietary changes can retard or prevent bone loss and what could retard and prevent bone loss and what medications might encourage new growth? These are questions to be answered by conducting extended stay research on board the international space station.
