Mars radiation levels tolerable to humans

By Elizabeth Landau, CNN

The Mars rover Curiosity has revealed that the radiation levels on Mars are not, according to initial measurements, lethal to humans.

“Absolutely, astronauts can live in this environment,” said Don Hassler, Principal Investigator for the rover’s Radiation Assessment Detector, at a press conference Thursday.

But don’t plan on booking a trip yet. You still have to add up the total radiation that you would soak up during the eight to nine months that it takes to get to Mars, and the eight to nine months back, not to mention the actual time on the surface. An astronaut would need to spend at least six months on the surface, and stay within the career limits for radiation.
