While the Artemis II astronauts have been protected from the icy vacuum of space on their journey, their bodies have nonetheless been left exposed to possibly high levels of radiation -- a danger of space travel that NASA is anxiously waiting to study.

Their trip around the Moon has taken the four astronauts farther into space than any human before -- more than 1,000 times the distance from Earth to the International Space Station.
