Christina Koch reached for the stars--and made it to space! As a kid, a love for science and engineering sent Christina to her school's rocket club and her backyard shed to build things with her dad. And that was all before she joined NASA, explored some of the most remote places on this planet, and finally blasted off for a historic space mission.
