KENNEDY SPACE CENTER, FLA. -- After a ceremony to commemorate the transition of the historic Operations and Checkout (O&C) Building high bay for use by the Constellation Program, representatives from NASA, Lockheed Martin, Space Florida and the state of Florida look at the banner, unfurled by Kennedy Space Center Director Bill Parsons (center), spotlighting the Orion crew exploration vehicle that will be assembled in the O&C. From left are Russell Romanella, director of the International Space Station/Payload Processing Directorate at Kennedy Space Center; Thad Altman, representative of the State of Florida; Cleon Lacefield, Lockheed Martin program manager; Parsons; Steve Koller, executive director of Space Florida (turned away); and Skip Hatfield, Orion Project manager. Originally built to process space vehicles in the Apollo era, the O&C Building will serve as the final assembly facility for the Orion crew exploration vehicle. Orion, America's human spaceflight vehicle of the future, will be capable of transporting four crewmembers for lunar missions and later will support crew transfers for Mars missions. Each Orion spacecraft also may be used to support up to six crewmembers to the International Space Station after the space shuttle is retired in 2010. Design, development and construction of Orion's components will be performed by Lockheed Martin for NASA at facilities throughout the country. Photo credit: NASA/Kim Shiflett
