Overview
The Cupola provides an observation and work area for the ISS crew giving visibility to support the control of the space station
The Cupola is important to astronauts aboard the ISS,[3] who enjoy using the module to view and photograph the Earth. Cupola replaced the Russian Zvezda for such photographs.[4] Previously they looked out of small portholes, or at best the 20-inch (50 cm) window in the US Destiny laboratory. The Cupola is berthed onto the Earth-facing port of the Tranquility module. Because of its shape and multi window configuration the Cupola has been compared to the cockpit window of the Millennium Falcon.[5][6]
Design and construction
The International Space Station Cupola was first conceived in 1987 by Space Station Man-Systems Architectural Control Manager Gary Kitmacher as a workstation for operating the station's
Once the idea was initially accepted, a number of people went to work. Human factors specialist Frances Mount began to develop the rationale and operational scenarios for the Cupola, and got considerable support from Chief Astronaut
Because of confusion between the responsibilities of the two contracts, both Boeing, which won Work Package 1, and McDonnell Douglas, which won Work Package 2, bid to build the Cupola. The McDonnell Douglas design was basically the same as NASA's, but Boeing's was smaller — a hexagon, with a single large circular overhead window, and a much shorter cylinder. The Boeing design had been considered but previously discarded, because it was unable to accommodate two crew members completely, and would instead require the crew to dangle their legs and bodies in the Node to which the Cupola would be attached. This design was the one ultimately built.
Manufacturing
Components of the Cupola were initially fabricated in California, and the windows in New York in the late 1980s, but as budgets were cut, the Cupola was a favorite target. Several times it was fought back into the program only to be cut again as not technically required. More than once the responsibilities for fabrication were bartered to one international partner and then another in exchange for Shuttle launch services and resources that the United States would provide on board the station in orbit. The Cupola made the rounds to Brazil and then finally wound up with ESA and the Italians in 1998, who completed it in 2003. Even then, the launch of the Cupola was repeatedly delayed until it finally made it into orbit in February 2010. The delivery method also changed from the Cupola being mounted on a SpaceLab pallet accompanying Kibo's external facility to being mounted on the European built Tranquility module as it was delivered.
The original barter agreement had ESA building two cupola modules for the ISS. This was later amended to just one.[8] The ESA-built Tranquility module and the Cupola together cost nearly $409 m.[9]
With final design and assembly by the Italian contractor Alenia Spazio (now merged into
The Cupola's outer framework is made from forged
Each window is composed of 4 separate layers ('panes'): An outer debris pane, two 25 mm pressure panes, and an inner scratch pane. Each pressure pane and debris pane is made from fused silica glass.[12] The panes can be replaced in-orbit after an external pressure cover has been fitted.[12]
The window shutters are manually controlled. Each window has a knob with a direct mechanical linkage to the outside shutter assembly. O-rings are used to prevent air leakage.[13]
