I get to travel quite a lot in my job, both for scientific conferences around the world (like one I was at just last week in Taiwan) and for team meetings for my spacecraft missions (for example, I was in England last month for a Cluster team meeting). Many missions these days have team members from around the world, each providing instruments and/or expertise - for example, MMS has instruments coming from Austria as well as the U.S., and Cluster (an ESA mission) has instruments from many countries. I also travel for educational outreach. For example, I have taken my Discovery Dome to reach 6000 students in Morocco last fall, and have done teacher or student events in Zambia, Ethiopia, Mexico, and many other places. I have interviewed some of my UK Cluster colleagues.. you can see them at my Cluster outreach website

One of the great things about participating in space science is that you have colleagues all over the world, all interested in science and how the universe works. I just wish I were more fluent in other languages... I speak some Spanish, German, and French but I'd love to be able to speak Chinese!
