Astronaut on 'Talk of Iowa'

Clayton Anderson waves during a spacewalk.

Greetings from space

Clayton Anderson, who earned a master's degree in aerospace engineering from Iowa State in 1983, waves to the camera during a July spacewalk at the International Space Station. Anderson's nearly five months in space featured spacewalks, station repairs, science experiments, technology tests and at least two hours of exercise a day. The native of Nebraska even engaged in some home-state ribbing with Peggy Whitson, the station's Expedition 16 commander and a native of Iowa. NASA photo.
