Mars missions will require up to three years in reduced gravity, so we need to make sure astronauts can not only survive but thrive as they move outward to explore this new world.

To avoid congestion, I get up at 5:10, grab a slice of raisin toast, and leave the house at 6 A.M. My husband, Tim Dunn, who works for an environmental agency, is still asleep when I slip out, and I find that rather annoying.

As a card-carrying space nerd and NASA's chief scientist, I love space movies, from 'Star Trek' to 'Star Wars' to my all-time favorite - 'The Dish', an Australian comedy that celebrates that first moment when Neil Armstrong stepped down onto the surface of our moon.
