Meet Jessica Meir, one of NASA's newest astronauts. After hearing this week that she's been chosen for the Class of 2013 recruits, Jessica joined me today on America Weekend to talk about what's ahead in her space future -- possibly including Mars. We also talked about her adventures in another extreme environment, doing scientific research in (and under!) Antarctica. That's her with an Emperor Penguin above.
