"For fun I play Irish music with my neighbors. We get together most Saturday mornings for a pot luck breakfast and music."

Where are you from?
I was born and raised in the Los Angeles area, near the coast. My father was an aeronautical engineer at the Rand Corp. in Santa Monica, Calif. My mother worked as a secretary.

Describe the first time you made a personal connection with outer space.
I guess there were a series of personal connections. I vaguely remember my father taking me outside to watch one of the first satellites pass overhead. It was probably Echo, but I think I was far too young to figure out what he was pointing at.

"I guess I got hooked on space through science
fiction ... I took away a vision of the future where
technology made life simpler and happier rather
than just busier and more complicated."
Gordon Johnston

I guess I got hooked on space through science fiction. One early book that made an impression on me was "The Forgotten Door" by Alexander Key. The main character comes from a time or place far more advanced than Earth in the present day. From the book I took away a vision of the future where technology made life simpler and happier rather than just busier and more complicated. At one point I read the whole science fiction section at my local library, reading my way across every shelf.

Several books by Arthur C. Clarke made an impression on me, including "The Deep Range" and "The City and the Stars." What I liked about "The Deep Range" is that it was about using the skills we learn in space to explore our oceans and feed the planet.

How did you end up working in the space program?
It was a lucky break. I was working on my master's degree in mathematics and I wanted to do space-related work. (I had applied to NASA's Jet Propulsion Laboratory (JPL) in Pasadena, but had yet to hear from them.) One day while looking through the Los Angeles Times I came across a want ad for mathematicians, which turned out to be for a contractor job at JPL working on the Viking 1 mission to Mars. I applied, interviewed and got the job. JPL liked my work, and when the Galileo mission to Jupiter got its new start a year later, JPL hired me as a permanent employee working half time on Viking and half time on Galileo.

Who inspired you?
I would have to say first my father and second, the writings of Arthur C. Clarke.

Although my father was a quiet man, he was not afraid to point out hypocrisy when he saw it, and in the days of segregation there was a lot of hypocrisy to notice.

My father was a competent engineer; he knew how to make things work. My father was also an airplane enthusiast. His hobby was to build accurate scale replicas of World War I aircraft. These replicas had gas engines and flew, controlled by "U-control" wires. I grew up helping him build, fly and repair these models.

Most Americans believe in the future, that the world we leave our children can be better than the world today; that it is our duty to work to make this true. Arthur C. Clarke wrote "The Deep Range" in 1957 when the world's population was approaching 3 billion. In this book he speculated that as the world's population grew to 6 billion, we would have to expand and farm the algae fields of our oceans in much the same way we have expanded and farm the grasslands on our continents. Today the world's population is approaching 7 billion and the UN medium projection is that we will peak at over 9 billion people later in this century. It is too late, there are too many of us, to go "back to nature," at least for the foreseeable future. But what we can do is use technology, including space technology, wisely and sustainably to gain the knowledge and capabilities to give all of us on Earth the opportunity to live rich and fulfilling lives.

What is a Program Executive?
I am currently a program executive in the Science Mission Directorate at NASA Headquarters in Washington, D.C. NASA currently runs its robotic space missions by having a team of three people at the Headquarters level who monitor the development and implementation of each mission. The program executive (PE for short) follows the engineering aspects of the mission; the program scientist (PS) makes sure the mission will achieve its science goals, while the resource analyst (RA) looks after the money and congressional reporting requirements.

I am currently assigned to the Planetary Science Division (PSD) and I am the PE for the Lunar Reconnaissance Orbiter (LRO) mission, which is orbiting the Moon. I am also the PE for a technology effort to develop new and improved propulsion systems for planetary spacecraft. I will be the PE for the next New Frontiers mission once the current studies are completed and the final mission is selected.

Tell us about a favorite moment so far in your career.
I have the most fun when I am learning new things or working with a team of dedicated people to understand a challenging problem or to assess widely varying technical options. I enjoy it when we turn a problem around, look at it in a new way and come up with approaches to solutions that were not obvious before.

Often in my line of work it can be years between when I work on technology or assess a mission option and when that technology or mission starts returning real science from space. Several of the instrument technologies I helped sponsor are now operating in space. When I worked in Earth Science I led the evaluation of several mission proposals, three of which are still operating (GRACE, CloudSat and CALIPSO). I feel a quiet sense of satisfaction when I see the new knowledge and useful results that come from things I helped make happen.

What advice would you give to someone who wants to take the same career path as you?
Look for a career, not just a job. Seek out work that you enjoy and believe in. This makes it far easier for you to get excited about and involved in the work you do, as well as be able to put in the extra effort needed to do well. A technical education is important, although it can be in any of a number of fields, as the main skill needed is the ability to understand complex problems and work them through to real solutions.

What do you do for fun?
I enjoy spending time outdoors and I ride my bicycle to work most days (except when it is icy or during thunderstorms when there is a chance of getting hit by lightning). I also enjoy music. When I moved to the Washington, D.C. area I met people who play traditional Irish music, so I have taken up the fiddle.

If you were talking to a student interested in science and math or engineering, what advice would you give them?
Here are a couple ideas:

1) Studying mathematics is like learning a foreign language; you need to spend time learning the vocabulary and the grammar before you can start appreciating the poetry. I did not start out in college as a mathematics major, so I ended up going an extra year. It was somewhere in my second year of college that I started to see mathematics as an art form made up entirely of concepts and ideas that fit together into a beautiful whole.

2) For engineering (or science), take the time to learn hands-on skills. Bicycle repair, for example, is a great way to learn first-hand how gears, levers and pulleys work. Bicycle repair is also a great way to learn the scientific method: You have a problem (the bike does not work), you come up with an hypothesis on the cause of the problem, then you have to come up with a way to test your hypothesis and either you have solved the problem, or more often than not (as in real science) you find your hypothesis was wrong and you need to come up with a new hypothesis. Repeat this process until the problem is solved.
