United Space Alliance Aft Technician Bobby Wright looks at the gaseous nitrogen pressure regulator in the left Orbital Maneuvering System pod on Space Shuttle Endeavour. The component showed pressure differentials during the launch count May 30, 2002, and mission managers elected to replace it after the launch was scrubbed due to weather concerns. The launch of Endeavour on Mission STS-111, Utilization Flight 2 to the International Space Station, has been rescheduled for June 5, 2002
