IamA SPACE.com journalist who just spent two weeks on a mock Mars mission, AMA!
NOTE: This AMA has now concluded. Thanks for your time and interesting questions!
I'm a space journalist who went on a two-week mission to the Mars Desert Research Station near Hanksville, Utah. My six-member team (Crew 133) spent our time setting up a new radio telescope, doing simulated "Marswalks" in spacesuits, and testing out protocols for medical procedures and astronomy, among other things. You can read about our experience on SPACE.com: http://www.space.com/24175-mock-mars-mission-complete-coverage.html
