My first and only ISS contact was with CDR Doug Wheelock on 8/29/10. Since I got an invite to hear Doug talk to students in Ashford AL on April 14th. It was a great opportunity to hand deliver the QSL for the contact. Doug visited a number of schools in Alabama and also was on the Rick and Bubba show.
CDR Wheellock gave a great talk for Ashford students. He said your math problems you do now give you problem solving skills you will use later in life. While Doug was the Commander on the ISS they had to solve a serious cooling pump problem. It took three spacewalks to resolve. And even with that challenge Doug took time to make contacts with schools and hams from the ISS.
