Editor's Note: Cady Coleman, Ph.D. is a NASA astronaut – a veteran of two space missions, who has logged over 500 hours in space. She is assigned to the Expedition 26 crew and is scheduled to fly to the International Space Station aboard the Russian Soyuz 25 in late 2010. This is part three of our year-long American Morning original series, "Counting Down Cady."

Houston, Texas (CNN) - It takes two people to help dress Cady Coleman for work.
The spacesuit she must wear for training at the Johnson Space Center here weighs more than twice the body weight of the petite astronaut.
"Some people think you might have a custom spacesuit, and you don't," she says. "They're in a generic size."
Pads are added and adjustments are made to ensure a custom, comfortable fit for each astronaut. The suit Coleman is training in is similar to the one she will wear if she must do a spacewalk next year while aboard the international space station.
In November, if everything goes according to plan, Coleman will blast off on a Russian Soyuz rocket for the station, where she will live for the next six months.
