I walked on the moon. This is my journey. But it didn’t begin when I stepped on board Apollo 11 on July 1, 1969. It began the day I was born.Becoming an astronaut took more than education, discipline, and physical strength. It took years of determination and believing that any goal is possible-from riding a bike alone across the George Washington Bridge at age ten to making a footprint on the Moon. I always knew the Moon was within my reach-and that I was ready to be on the team that would achieve the first landing. But it was still hard to believe when I took my first step onto the Moon’s surface. We all have our own dreams. This is the story of how mine came true.
