I grew up in the Apollo era. Making spacecraft go from one place to another, and in particular making them dock as in 2001: A Space Odyssey was just too cool. So, 40 years after the release of that movie, here I am working for a company that specializes in spacecraft guidance, navigation, and control, and in particular, specializes in rendezvous and proximity operations for human-rated spacecraft . And I don't even have a degree in this field!

NASA was pretty much gutted while I was in college, with human spaceflight taking the biggest hit. My high school dreams were just juvenile pipe dreams. I majored in physics, did a senior research project with my previous year's stat thermo instructor on a fairly new aspect of physics that is now called chaos theory. I was accepted into a couple of PhD program, one with some money attached: I was good to go. Not quite. My adviser convinced me, two days before graduation and 100 miles way from school, that I did not want to go into physics as a career. I was the best man at a wedding. I got a phone call right before the wedding. How he found out where I was, how he found some weasel way to keep from graduating (I took five liberal arts courses in my first two years, three in my last two years, instead of four and four), and why he did that are beyond me. A good friend at the wedding had graduated a year before I did (also in physics) asked whether petty school politics such as this was what I wanted to face for the rest of my life. "I could help you get a job at NASA -- unmanned space rather than human spaceflight, but it is still NASA". So, here I am. Not quite. It took another twenty years to get to the point where I was doing exactly what I envisioned doing in high school.
