One small step for mannequins, one giant leap for mannequin kind?
NASA will send two dummies into space to orbit the moon next June.
Helga and Zohar will be used to test new equipment designed to protect astronauts from cosmic radiation.
The science educator known as Nanogirl, Michelle Dickson, says that's because the plan is to send the first woman to the moon in 2024.
"Women are very different to men around risks of cancer. Your sending women to the moon or a long term space program, it is not as easy. It's quite restrictive, actually, as we have a lot more risk. We have to be in space for less time."
Dickinson says the amount of radiation the female mannequins are exposed to around vital organ areas will be measured.
