NASA's Orion spacecraft will need to protect astronauts from dangerous radiation when they visit the moon in the upcoming Artemis missions.
When NASA’s Artemis I mission launched on its journey around the moon in 2022, there weren’t any astronauts aboard — but there were two torso-shaped dummies, named Helga and Zohar, who were designed to test how much radiation astronauts can expect to be exposed to when they do eventually fly on the Artemis II and III missions.

But it’s not just the environment inside the capsule that is important. The study also found that the orientation of the spacecraft affected exposure, and that by turning the spacecraft 90 degrees during a flyby of the inner Van Allen belt, the exposure was reduced by 50%.
