the Cupola windows. Laurie Weaver, who had just started with NASA as a student intern, began to work on a series of different configurations for the Cupola. She started with Kitmacher's idea, based on the Shuttle Aft Flight Deck, in this case two Aft Flight Decks mounted back to back, placed atop a short cylinder. An inexpensive mock-up made of PVC tubes was built and tested underwater, where critical dimensions could be measured to ensure that two crew members in zero-g would have adequate access. Then she built a series of small cardboard models, looking at a variety of different alternative shapes. The different configurations and their positive and negative attributes were presented at a series of Crew Station Reviews over the next year in which participants rated each. The Cupola that evolved was octagonal in shape, with eight similar windows around the periphery, four quadrant windows overhead, and mounted on a cylinder. The module was designed to fully contain at least two crewmembers "floating" side by side in zero-g neutral body posture. About this time, Kitmacher and designer Jay Cory applied the term Cupola for the first time. Kitmacher wrote the requirements and the name into the Man-Systems Architectural Control Document and into the requests for proposals for Work Package 1 at MSFC and Work Package 2 at JSC. Later, Kitmacher went on to lead the Man-Systems group, leading the first lunar outpost and moonbase studies and the Cupola reappeared on several of his rover and module designs. 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
