Involving 15 countries and hundreds of contractors, the International Space Station (ISS) gives new meaning to the phrase “high-flying, international joint venture project.” Four massive solar arrays, with a square acre of coverage, will deliver most of the station`s 110 kilowatts of electricity. The arrays will be mounted to a 360 foot-long truss assembly, supported by aluminum bulkheads like the one pictured. Here, technicians complete machining the bulkhead at Boeing facilities in Huntington Beach, Calif. The part and its associated truss are scheduled for launch with the U.S. Laboratory module on space Shuttle mission STS-105 in early 2000.
