Dennis: What do you do for a living, Frank?

Frank: I am an engineer. I have been working for NASA for over fifteen years.

Dennis: Wow, that sounds fascinating. What projects have you been involved in?

Frank: Well, until recently, I was heavily involved in the Cassini . I don't know if you're familiar with it or not - it's one of NASA's most expensive and projects. We are sending a to explore Saturn and its moons.

Dennis: That sounds really interesting. Are you in any way involved in the construction of the International Space Station?

Frank: Actually, that's what I'm working on now. I'm currently a technical between NASA and several European space agencies. It's an interesting job, but it can be a bit too much at times. The International Space Station is probably the largest international ever attempted, and I am constantly dealing with technical difficulties, budget problems, and delays. It's not easy the efforts of all those countries. I have been to Europe three times in the last month, and I have to go to Kazakhstan next week.

Dennis: I understand there's some surrounding the space station. Don't some people worry that NASA is spending too much money on the project?

Frank: Many experts have complained that the project has grown out of control and become far too expensive. But I look at it as more than a space station; I believe it's helping international scientific cooperation. It's nice to see the scientists of the world working together to create a to the future.
