"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."
