If you think it's really claustrophobic to live in work in outer space, wait till you hear what it's like aboard the International Space Station.

The secret that we keep from everybody on the Earth is that the space station is enormous.

Astronaut Katie Coleman joins us in the hour ahead on travel with Rick Steves to share what

it's like to spend nearly six months conducting scientific experiments with an international crew.

But being weightless does take some getting used to.

When new people first get up there, they're sort of clumsy and they're come flying through the lab and they knock everything

You've met guides to some pretty unusual places well off the beaten path here on Travel with

Rick Steeves.

Today, we get the inside scoop on what it's like aboard the International Space Station

Katie eventually became an Air Force lieutenant

and a mission specialist on the Space Shuttle Columbia.

Katie has also lived weightless for nearly half a year

while conducting experiments on the International Space Station.

She joins us today from the studios of Johnson Space Center in Houston to share what it's like to live and work in outer space.

Katie, thanks for joining us.

You're welcome. I was laughing because my mom used to tease me that at last I had a job in a place that I'd been
