The US space agency will expose between 18 to 28 of the moneys to low
doses of radiation daily to better understand the effects of long-term
exposure outside Earth's protective magnetic shield.

American anti-animal testing group, the Physicians Committee for
Responsible Medicine, has launched a protest asking concerned citizens
to tell NASA Administrator Charles Bolden to put a stop the
experiment.

"Radiation experiments involving nonhuman primates commonly involve
restraint and other cruel procedures," the organization claims.
"Monkeys, like other primates, are highly intelligent, have strong
family bonds, demonstrate empathy, and, most importantly, suffer."
