Using the radiation sensor aboard the NASA rover Curiosity, scientists estimated that a round-trip voyage would expose astronauts to about 662 millisieverts. That’s similar to getting a full-body CT scan every five or six days for a year.
As plans for deep space exploration ramp up, radiation is a big concern. NASA aims to send a crew to orbit the red planet by the mid-2030s and private outfits are seeking volunteers for a Mars flight.
