Mars trip threat
LOS ANGELES- Astronauts traveling to and from Mars would be bombarded with a lot of radiation according to new research. NASA is aiming to send a crew to orbit the red planet by the mid 2030s and private companies are seeking volunteers for a Mars flight. Using the radiation sensor aboard the NASA rover Curiosity, experts calculate a round-trip to Mars would expose astronauts to the same amount of radiation as getting a full-body CT scan every five or six days for a year. The latest findings do not include exposure to radiation while on the Mars surface.
