Helga & Zohar are mannequin torsos that took flight on Orion. Rather than astronauts, a mannequin named Commander Moonikin Campos helmed the spacecraft, with two mannequin torsos called Helga and Zohar along for the ride. Helga and Zohar will experience deep Space radiation inside Orion.
They are made of materials that mimic the soft tissue, organs, and bones of a woman to test how radiation passes through the human body.
Zohar will wear AstroRad, a radiation protection vest, to test how effective it could be if future crews encounter a solar storm, while Helga will be unprotected. The AstroRadvest was recently tested on the International Space Station.
