In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, an overhead crane lowers the Tranquility module, or Node 3, toward a work stand. The module will be delivered to the International Space Station on the STS-130 mission and will eventually house the life support equipment necessary for the space station's permanent crew of six. It will also accommodate the European Space Agency's Cupola observation module, a seven-window, dome-shaped structure. Image credit: NASA/Jim Grossmann May 26, 2009
