 As the daughter of two NASA rocket scientists, I've been surrounded by astronauts and spacecraft my whole life. As a journalist, though, I've only ever watched from the sidelines. Now I'm going to find out what it really takes. From the physical demands of the job to being fitted with my very own spacesuit. I'm going to train for the most amazing job of all. And then I'm breaking free of Earth's gravity. I can't control where I'm going. I can tell why people become astronauts though. George Clooney moves so much faster. Suit me up. I'm Lauren Grush and this is Space Craft.
