Mission specialist Kathryn "Kay" Hire, at left, assigned to the crew of space shuttle Endeavour's STS-130 mission, takes a tour of the Tranquility Node 3 module in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida. Assisting her, at right, is Chris Hardcastle, an STS-130 flight crew representative with United Space Alliance.
Tranquility is a pressurized module that will provide room for many of the International Space Station's life support systems. Attached to the node is a cupola, a unique work station with six windows on its sides and one on top. Tranquility is the payload for the STS-130 mission. The module was built for the European Space Agency by Alenia Spazio in Turin, Italy. Cupola resembles a circular bay window that will provide a vastly improved view of the station's exterior. Just under 10 feet in diameter, the module will accommodate two crew members and portable workstations that can control station and robotic activities. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects. Endeavour is targeted to launch Feb. 4, 2010. Photo credit: NASA/Jack Pfaller
