Another Reason Why ISS Is Important For Exploration

One therapeutic dose of radiation causes 30 percent spongy bone loss in mice, American Physiological Society

"Astronauts lose 2% of bone mass for each month they are exposed to the effects of microgravity. So far, astronauts have not been exposed to the increased radiation of outer space, but that will change when they undertake a proposed 30-month trip to Mars, Bateman said. NASA has focused on radiation's cancer-causing properties and its ability to compromise the central nervous and immune systems. But the effect on bone health is an unexamined concern."

Editor's update: I am certain Bob Zubrin will fire out yet another ill-informed rant about how these experts don't know what they are talking about. C'mon Bob, fire away.
