/u/mcmeekin91 on I am Jeff Hoffman, MIT Professor of Aerospace Engineering and former NASA Astronaut. Ask Me Anything!19 Feb 2015, 19:28 UTC
Dr. Hoffman I'll be taking your course this march and wanted to say thank you for doing this course. I'm just doing this course pure out of my curiosity of understanding aerospace engineering more then I do now. I don't know if you know the answer to this but from my understanding when the curiosity rover was on it's way to Mars it experienced a lot more radiation then we expected. Have we figured out a way to limit the amount of radiation a person would be exposed to on a trip to Mars to make it safe?
