Suni Williams and Butch Wilmore originally planned to stay just a week on the space station, but problems with their Boeing vehicle forced them to remain there.

For Butch, the day starts at 04:30, and as for Suni, she makes a slightly kinder 06:30 start. Both have said they enjoy the two hours or more of exercise they must do daily to combat the loss of bone density from living in space. "Your joints don't hurt, which is quite nice," Butch has said.
