BAGHDAD, Iraq (WRN) - Wisconsin astronaut Jeff Williams and a partner aboard the International Space Station talked for about 20 minutes Tuesday with troops in Iraq.

Williams is from Winter in northwest Wisconsin. He and T.J. Creamer floated in their weightless cabin while answering questions from Wisconsin National Guard troops and others at a studio in Baghdad. Williams, a retired Army colonel, said there’s not a day that goes by when he and his fellow astronauts don’t remember the service and sacrifice the troops are making.

NASA said Williams and Creamer asked for the satellite meeting. Creamer is also an Army colonel. Williams is on his second mission aboard the International Space Station. He’s been there since October, and is due to return in the spring.

Among other things, the soldiers asked the astronauts how they stay fit, how they keep in contact with their families, and how they fixed a broken system on their craft that processes urine. Williams and Creamer said they use a stationary bike to stay in shape. And they didn’t fix the urine system yet. It’s being stored until that gets done.
