Sunday morning, space shuttle Endeavour is scheduled to blast off on a mission to the space station to deliver the Tranquility node, which is essentially a new room for the outpost. Attached to this room is a special structure called the cupola. It has seven large windows — the central, circular window is about 31 inches across — so astronauts can float inside and be surrounded by a panorama.
