After a career that led me from the Air Force Academy to Space Command to now, I became a systems engineer, and recently I was drawn into an engineering problem associated with NASA's mission to Mars.
Pályafutásom során, amely a Légierő Akadémiától az Űrparancsnokságig ívelt, rendszermérnök lettem. Nemrég a NASA  Mars-expedíciójával kapcsolatos egyik mérnöki feladatba vontak be.
