Radiation on trip to Mars near lifetime limit
Washington (AFP) May 30, 2013
Astronauts who travel on future missions to Mars would likely be exposed to their lifetime limit of radiation during the trip, not to mention time spent on the Red Planet, scientists said Thursday. The measurements were made aboard the Mars Science Laboratory, an unmanned NASA rover and mobile lab that set off for Mars in 2011 before landing 253 days later in August 2012, said the report in the US journal Science. "In terms of accumulated dose, it's like getting a whole-body CT scan once every f ... read more
