I might not normally agree with the People for the Ethical Treatment of Animals (PETA), but when it comes to cute little monkeys, squirrel monkeys to be precise, I do...
PETA is protesting in front of various NASA sites about a study in which the space agency will expose 18 squirrel monkeys to the amount of space radiation in one big dose that astronauts would receive on an entire multi-month mission. In other words, a reallly high dose.
Here's a recent clip of PETA explaining the situation:
Come on NASA, can't you use opossums, or perhaps rats, or maybe some of your own engineers for the study?
