I grew up on the south side of Chicago in the 1960s, and I think there was a synchronicity of events that inspired me to be an astronaut, and, of course, the backdrop is nothing less than Mercury, Gemini, and Apollo. That was a time in our nation where we aspired to great things, and we achieved them.
