When I think about this, I usually think about two particular projects that I experienced in different ways. I spent seven years of my life on the Aura mission. I was the observatory manager, and so much of my life was invested to make that mission happen, so I feel a tremendous amount of accomplishment in its success. When I think of that spacecraft, I think about how well I knew every nook and cranny of it. It is a very complicated spacecraft, and I knew every little problem that we had encountered and solved, and every little flaw that we had to live with that was built into it. That spacecraft was launched in 2004 and was designed for a five-year lifetime. It is still operating and performing excellently today. So I feel a tremendous amount of pride in it.
And then the other one would be Curiosity. I was the Acting Deputy Director for Planetary Science at the time we landed Curiosity on Mars. So when I came into headquarters, I was there for the three years leading up to its launch. I was part of the most intense period of the project, where there’s a tremendous amount of pressure. When you do these planetary landings, Mars in particular, you don’t have a lot of margin of error. Everything’s got to work just right, and it did. It was one of the most stressful days of my career waiting for the landing on Mars. And again I had to know everything, not just with generally what could go wrong, but specifically what could go wrong. That was an incredible night!
