I've been so lucky in my 28+ years at JPL, and I've almost exclusively worked in mission operations as a propulsion engineer. I like to say we have geniuses build these amazing spacecraft so monkeys like me can fly them! I ended up working on Galileo for over 7 years and Cassini for over 21 years, most of them as lead propulsion engineer. Part-time assignments on Deep Space One, Stardust, Mars Exploration Rovers, Mars Science Laboratory, Deep Impact, Spitzer, SMAP, and Dawn have been fabulous as well. However--and perhaps most unbelievably--I am now on the Voyager flight team, more than 41 years after launch! The actual mission that defined my future is now part of my every day life, and I just can't believe my good fortune!
