The International Space Station might be bigger than a football field, but it's equipped with just seven permanent sleeping pods, each about the size of a phone booth. NASA has to get creative for those rare times when there are more people than beds.
When the four new crew members arrive, they'll join seven already on board. Two astronauts will have to sleep in the docked SpaceX capsules. And that leaves two others without beds — but that's not a problem. "The nice thing about sleeping in space is that just about anywhere can be your bedroom," said NASA spokesman Dan Huot.
